-
Will CGON go on my vehicle?Yes! The CGON unit goes on any fossil fuelled engine and therefore suits just about any petrol, diesel or LPG fuelled engine.
-
How often should my tyres be checked?Ideally your tyres should be inspected at least once a month and before any long journey. Tyre checks should include checking the air pressure, the overall condition and tread depth. Do not forget to check the spare or the compressor and sealant if no spare was fitted.
-
Will CGON go on my motorhome?Yes! The CGON unit goes on any fossil fuelled engine and therefore suits just about any petrol, diesel or LPG fuelled engine.
-
What should I do when checking my tyres?Tread depths should be checked to ensure they meet the legal minimum regulations. Pressures should be checked in line with the vehicle manufacturers’ recommended settings. Take care to increase the pressure if the vehicle is heavily loaded as instructed in the manufacturers specifications. The tyre/s should also be given a thorough visual inspection to look for any cuts, lumps or bulges and ensure there are no foreign objects embedded in the tyre/s.
-
What are the applications of Advanced Driver Assistance Systems (ADAS)?ADAS typically includes Traffic Message Channel (TMC), Intelligent Speed Adaptation (ISA), Vehicular Communication Systems and other driver assistant systems. The systems are as follows | Vehicle Cab | (i) Lane Departure Warning System (ii) Lane Keeping Assist (iii) Traffic Sign/Signal Recognition (iv) Night Vision System (v) Driver Status Monitor (vi) Electric Vehicle Warning (vii) Hill Descent Control Front | (i) Parking Assist (ii) Adaptive Front/Lighting System (iii) Adaptive Cruise Control (iv) Pedestrian Detection (v) Emergency Brake Rear | (i) Reverse Image (ii) Parking Assist (iii) Rear Collision Warning Side | (i) Surround View (ii) Blind Spot Detection

Will CGON affect my vehicle insurance?As with any modification to your vehicle, such as a tow bar, stickers (yes, really!) or a performance air filter, you are obliged to inform your insurance company. This responsibility lies with you. However, it should not be assumed that your premium will increase as a result of fitting a CGON product. As yet, we have yet to hear from anyone that has had their premium increased, usually the insurance company just give thanks for letting them know. At the end of the day, the obligation it yours. If you choose to inform your insurance company, the CGON ezero should be described as a fuel additive for emission reduction or an emission reduction unit. Please note that the ezero does not affect your speed or your safety and is not visually desirable (i.e appealing to thieves).
-
What is the minimum legal tread depth?Current UK law requires car, van and LCV drivers to have at least 1.6mm of tread across the central three-quarters of the tyre, around its entire circumference. For trucks (vehicles exceeding 3.5 tonnes g.v.w), current tread depth legislation requires that they must have a minimum of 1mm of tread in a continuous band throughout the central three-quarters of the tread width and over the whole circumference of the tyre. The same regulation applies to regrooved tyres. Meanwhile, for motorcycles over 50cc it is 1mm across ¾ of the width of the tread pattern and with visible tread on the remaining ¼. For motorcycles up to 50cc the law requires that all the grooves of the original tread pattern must be clearly visible.
-
When should I use the ADAS Calibration service?Under normal circumstances and to ensure the integrity of the system is maintained we would advise conducting an ADAS calibration after general repair to suspension components, geometry adjustments, windscreen replacement, bodywork replacement or repair following an accident. When disassembling or reinstalling monitoring components such as cameras, radars, and sensors, replacing the vehicle ECU, or the vehicle height has been changed, auxiliary and other systems need to be calibrated. To provide an example the Adaptive Cruise Control (ACC) calibration needs to be performed in the following cases | (i) Repair or replace the Adaptive Cruise Control (ACC) radar sensor control unit (ii) ACC radar sensor deviation angle out of normal range (iii) Adjust position of the ACC radar sensor on the vehicle body (iv) Repair or replace bumper or radiator grill (v) Adjust chassis Our technicians are certified professionals who will provide you with the necessary safety advice to ensure the intergrity of your vehicles operating systems are managed and maintained following any works that you may have done at our workshop.
-
What are the fines for driving with illegal tyres?Drivers who fail to comply with the regulations face a fine of up to £2,500 and three penalty points for each illegal tyre. Do not risk a fine, points or your safety, contact us without delay for all your vehicle requirements.
-
Will CGON affect the warranty on my vehicle?Having a CGON ezero system installed will not impact on your vehicle manufacturer's warranty unless a defect occurs and it can be proven that it was a direct result of the CGON modification. This is the same for anything you install, be it telematics, aftermarket products or additives used in fuels or tank cleaners etc. CGON's ezero systems have been installed across the world in hundreds of vehicle applications and have been tried and tested for millions of miles in various atmospheric conditions. CGON are pleased to state that none of the vehicles or engies have suffered as a consequence of installing the ezero products.
-
What does the ADAS front view camera do?The front-view camera captures what is in front of the vehicle. It is used in a number of ADAS systems, including Lane Departure Warning (LDW), Lane Keeping Assist (LKA) and Traffic Sign/Signal Recognition (TSR) systems, often in conjunction with other sensors, cameras or sensing systems to provide input data.
-
What does the ADAS 360° camera do?The 360° or Surround View Camera System uses multiple camera views to create one 360° top-down (bird’s eye) view surrounding the vehicle. This system is used in both passive (displayed instructions) and active (autonomous) vehicle parking assist systems.
-
Why is tyre tread depth important?Adequate tread depth is essential for good grip on wet roads as the tread pattern helps to remove water from between the tyre and the road surface. Drivers with insufficient tread depth face longer stopping distances, reduced grip and an increased risk of aquaplaning.
-
Can I get a refund on my vehice tax from DVLA?As far as the DVLA are concerned, that is a legislative matter and one that unfortunately we have no control over. They have yet to release anything to deal with retro fit technology.
-
My vehicle has been chipped / remapped, can I still have a CGON unit fitted?"Yes! You can however you may not see significant emission reductions due to the remap considerably increasing emissions.
-
What does the ADAS radar sensor do?ADAS radar sensors detect fixed and moving objects at different distances around the perimeter of a vehicle. Different Radar types and frequencies are used in various ADAS systems. Ultra short-range radar (USRR) and short-range radar (SRR) provide data for blind-spot detection (BSD) and lane-change assist (LCA), while systems including adaptive cruise control (ACC) use longer range radar.
-
Why is correct tyre pressure important?To ensure your safety on the road your vehicle needs to have the correct tyre pressure. If the tyres are under or over inflated then handling and grip will worsen, potentially causing irregular or unpredictable car behaviour. Tyres with insufficient air are also more likely to suffer from a sudden rapid deflation and will suffer premature wear on the outside edges of the tyre. The wheel rim and tyre will be more susceptible to impact damage. Over-inflation results in less comfortable ride, a reduced area of contact with the road giving less grip in the day and accelerated wear on the tread centre . The benefits of a properly inflated tyre, include reduced running costs and longer tyre life.
-
Where can I find the correct tyre pressure for my tyres?The vehicle manufacturers’ handbook contains this information. It is also often displayed inside the fuel filler cap or driver’s door sill for your convenience. We are able to provide this information if you do not have access to this information, contact us with your enquiries.
-
Is the CGON unit guaranteed?We guarantee the unit for twelve months.
-
Why do I need to calibrate the ADAS system?Your vehicle relies on the cameras/radars/lasers used by the ADAS being in the correct alignment to function properly. As the system is not automatically self adjusting it is important to ensure the ADAS is calibrated to maintain the integrity of the vehicle's safety system. The consequences could be devastating if not.
-
How many different types of ADAS calibrations are there?There are two types of calibration available: static and dynamic calibration. Depending on the vehicle make and model, either static or dynamic calibration is required. However, some vehicles will require both static and dynamic calibration to properly calibrate the system. Static calibrations require specific targets or patterns unique to each vehicle manufacturer. These types of calibrations must be performed indoors with the vehicle stationary throughout the calibration process. Dynamic calibrations are performed by driving the vehicle on public road under specific parameters such as vehicle speed, road condition, weather, and duration of time.
-
What causes irregular tyre wear?Irregular tyre wear can be caused by a variety of contributing factors. Repeated scuffing of tyres against kerbs, aggressive driving, the over or under-inflation of the tyre, worn suspension components and most commonly misaligned geometry, to name a few. We offer a free health check that will provide you with the necessary information to address these issues to eradicate irregular tyre wear and prolong tyre life, saving you money long term. Philips Garage Limited are a leading geometry specialist offering a geometry check free of charge to all customers that will verify any need for adjustment. Component replacement and geometry adjustments are priced on individual requirements following investigation.
-
Does the CGON unit store hydrogen?No, the system is not pressurised and only produces hydrogen when the engine is on, once the engine is turned off the cell stops producing.
-
What lifespan can I expect from a tyre?Tyre life is very dependent on the way that they are used. A set of tyres well maintained and used exclusively on motorways can return a much higher mileage against tyres badly maintained and ill-treated in a city centre and urban environment.
-
After collision repair, the vehicle did not have any MIL or DTC codes related to ADAS, do I still need to perform ADAS calibrations?"Depending on the repairs that were done, ADAS calibrations are highly recommended in the interests of safety. Some vehicle manufacturers require ADAS calibrations when certain parts (sensors, cameras, brackets, bumpers, etc) have been removed and installed regardless of any active MIL or DTC codes. The force from the collision could have bumped the ADAS sensors out of alignment. Performing the ADAS calibration will ensure the vehicle is returned to its pre-collision condition.
-
How is the ADAS calibration verified as being successful?Once the calibration process is complete, a post-calibration diagnostic scan is performed to confirm any existing diagnostic trouble code has been cleared and a calibration certificate is issued along with any other necessary documentation following the workshop appointment. If the calibration was not successful, this would be investigated, communicated and addressed as necessary.
-
Is the CGON unit dangerous?No, the system is not dangerous in anyway.
-
How far / fast can I drive with a Run Flat tyre in a deflated condition?Recommendations in the area may differ from tyre manufacturer to manufacturer and drivers should always consult the vehicle manufacturer’s handbook for the distance that can be travelled and speed driven. Please note that standard tyres should not be run without air or this will cause irreparable damage.
-
Are pre / post diagnostic scans performed?Yes, a pre-calibration diagnostic scan is performed before any calibration. This verifies the vehicle’s equipped ADAS system and checks for any stored diagnostic trouble codes. After a successful ADAS calibration, a post-calibration diagnostic scan is also performed to verify all diagnostic trouble codes have been cleared.
-
What are winter tyres?Winter tyres are designed to specifically cope with snow and ice, as well as cold and damp conditions. Below 7 degrees celsius the tread compound in normal tyres begins to harden, providing less grip. Winter tyres use advanced silica compounds so they remain pliant in cold temperatures, giving more grip and shorter stopping distances. They also have specially designed tread patterns to give superior grip on ice and snow.
-
How long will the CGON unit last once it is fitted?The life of the unit depends entirely on the environment and application it is kept in, but on a normally used domestic vehicle we would expect the box to to last indefinitely. As there are no moving parts, it really is a question of whether the box is damaged in any way such as in an RTA.
-
How long does an ADAS calibration take?ADAS calibrations can take up to 4 hours, depending on the vehicle make, model, and ADAS system to be calibrated.
-
Should I fit winter tyres in the winter?In the UK it is not a legal requirement although TyreSafe recommends they are fitted from October to March especially as they are the safest option in snow and ice, plus cold and damp conditions. UK drivers travelling to certain European countries may be required to fit winter tyres and this information is available from the Department for Transport.
-
Can I get the CGON unit put on another vehicle if I decide to change my vehicle?Yes! The unit can can be tranferres to another vehicle by a trained CGON installer.
-
What do the sidewall markings mean?The sidewall markings provide descriptive information about the tyre. The most important markings for drivers in the UK are size and type, aspect ratios load and speed rating. This sequence of numbers on your tyre (for example 255/55 R16) indicates the size of the tyre. This is important as you will need to ensure that any tyres you fit to your vehicle are the correct size as specified in your vehicle handbook. These tyre numbers mean (in relation to the above example): 255 – Tyre Width This indicates the width of the tyre in millimetres from sidewall to sidewall. 55 – Aspect Ratio These digits express the height of the tyre sidewall expressed as a percentage of the tyre width. In this example, the tyre height is 55% of its width. R – Tyre Construction The letter ‘R’ indicates that the tyre is of radial construction, as most tyres manufactured today are. Other types of construction include ‘B’ (bias belt) and ‘D’ (diagonal). 16 – Wheel Diameter This figure signifies the size of the wheel rim in inches that the tyre is intended to be fitted to. When contacting us to order or request an estimate for tyres please ensure you have this number sequence noted from your vehicle to advise our team.
-
How often does the CGON unit need to be topped up?You should schedule a visit to our workshop to top up the electrolyte liquid every 6'000 miles or so, or when indicated on the wireless key fob that comes with your ezero as standard.
-
Are your technicians certified to carry out an ADAS calibration?Yes! We have invested in training, certification and equipment to provide this service.
-
Are you Insurance Industry Requirements (IIR) Compliant?Yes! We meet requirements and are compliant with industry regulations.
-
What is tyre labelling and what does it mean?From 1st November 2012 all new car tyre labels will display three key measures that will rate the tyre’s fuel efficiency, wet braking performance and exterior noise emission characteristics. The labels will help explain to motorists how tyres perform in these three key areas and help them make a more informed choice about safer and more environmentally friendly driving.
-
Does the CGON unit need to be serviced?No, just topping it up with our electrolyte solution every 6'000 miles or so, or when indicated on the wireless key fob that comes with your ezero as standard.
-
How will I know when the CGON unit is working?You will have a wireless device which will indicate your cell is on and when it requires a top up.
-
Should I fit four new tyres at a time?It’s better to fit all four tyres at the same time but if that is not possible then fitting two tyres at a time, and as a pair to get the best handling and grip on each axle, is the next best option. As a last resort, then a single tyre can be replaced. In all circumstances, seek our technicians advice before replacing any tyres.
-
Which is the best axle to place new tyres on?New tyres on the rear axle provide better driver control on wet roads. This is because tyres with deeper tread are better at displacing water and give better grip. If the new tyres are fitted at the front the car, then it is more likely to oversteer when grip is lost in wet weather, which is much harder to control than understeer. Oversteer is when the rear of the car slides sideways, and understeer is when the front of the car slides.
-
Are there any guarantees on savings?This depends on the vehicle you drive and how you drive it. The system will provide you with a fuel enhancement of up to 20%% and will reduce your emissions by up to 80%.
-
How long does it take to install the CGON unit?Most installations take between 1 and 2 hours.
-
Can I fit the CGON unit myself?No, this is a specialised product and requires to be installed by qualified, certified personnel. Our technicians at Philips Garage are certified, authorised installers.
-
Where will the CGON unit be fitted on my vehicle?It is normally installed within the engine bay, however if the room is limited we will install the unit behind the front grill of your vehicles. The unit will not be visible.
-
I have seen similar systems before - what makes CGON different?It utilises the latest modern technology, is CE marked, manufactured to ISO 9001 and has been proven to work by Emission Analytics in real road conditions.
-
How has the CGON unit been tested?Extensively, both with real world driving and by Emissions Analytics in real road conditions and against 7 British Standards.
-
If the CGON unit runs out of water can I still use my vehicle?Yes, your vehicle will return to normal asipration if there is not enough water to operate. Schedule an appointment in our workshop to get the electrolyte liquid topped up at your earliest convenience.
-
Can distilled water be used in the CGON unit?It is NOT solely distilled water that is added to our system, included is our electrolyte solution which makes the hydrogen. Just using distilled water will degrade the electrolyte concentration. When a top up is required, schedule your appointment at Philips Garage, our trained, certified technicians will top up your CGON unit using the correct electrolyte liquid.
-
How does the CGON unit affect BHP or torque?It does not increase the BHP, however for those towing or carrying heavier loads you will find a slight increase in torque allowing for less gear changes and a smoother drive.
-
Does the CGON unit have an on / off switch and where is it located?The system is switched on and off by the vehicle's ignition. You also have a wireless fob which indicates on / off. To switch the system off completely (e.g to carry out mechanical works etc) theree is a fuse connector holding the fuse which can easily be disconnected.
