DPF And Carbon Cleaning in Tonbridge
Poor Servicing and Carbon buildup
The images above are just a Small selection of what we see in the workshop and endeavour to clean to restore correct operation of the engine.
The problem today is that due to long service intervals recommended by the manufacturer based on trying to sell the car to lease companies, and the short shop start driving done by the majority of us today leads to the enclosed.
In an effort to bring emissions down and make for a environmentally better world the engines are designed with what is know as lean burn technology, which in some cars involves 4 different fuelling strategies based on throttle position, engine speed, road speed and many sensors and flaps, so this in turn requires better maintenance which unfortunately does not happen.
If you are doing approx 10,000 miles a year with a great amount of motorway work as per the reps then generally all will be well but with high street driving school runs and shopping this does not happen and so the cleaning processes built into the vehicle known as regeneration does not occur as the catalytic converter (Cat) or the Diesel Particulate Filter (DPF) never reaches the required temperature of 350 deg +.
This then leads to build up of carbon in all areas of the engine and exhaust system and causes some serious problems, which leads to EXCESS fuel consumption, poor running, and disintegration of components. Picture 8 is a manifold on a BMW that melted.
ONE OF THE BIG FACTORS IS OIL
There are numerous grades of oil and manufacturers are constantly changing them so there is NO ONE OIL for all cars and even the same model could have different oil based on engine code, which is why we check every time and offer a lifetime guarantee on the oil we use, in fact in our workshop last count there were 20 engine oils alone.
SERVICE EVERY 6000 miles even if only an oil change and BG Flush
Here at Nev'll Fix It we have spent many years and hours researching a product that will assist with the cleaning and prevention of the above and the product we now use and have done for some years is made by a company called BG (https://www.bgprod.com/) This is an American company that has had phenomenal success with their chemicals because THEY WORK.
The products that you buy in places like Halfords etc are NOTHING like BG because of the chemical compositions and H&S.
When you book a service with us we ALWAYS recommend a BG service pack, this is not about us making money as we make very little, its about us caring and wanting to offer our customers the best out there. The company is that confident in their ability that they are prepared to offer a free 100000 mile warranty if you maintain as specified and continue to use the product at each service.
