It is a well-known fact that almost all modern engines of today use a fuel injection system to deliver fuel directly to engine combustion chamber. Delivering the fuel in this way allows for improved engine efficiency which results in less pollutants and better fuel economy.

Modern engine tuning today is typically done automatically and controlled by the engine management system which manages correct fuel / air ratios of fuel through the fuel injection system.Due to the location of the fuel injectors, on today's modern engines, fuel injectors get heat soak when the engine is turned off.

Passed my car MOT with the horn not working before there checks and also after when I drove home I noticed it still does not work. I also had a mechanic look at my car a week after my MOT was passed by these guys and he said my front break pads were completely gone and shattered and it was very dangerous me driving my car as it was not allowing me to break and has now scraped my break discs.

Great service: we were on holiday and my car started squeaking. They diagnosed a misaligned brake pad and repaired it very quickly.

Went today, stood around like a spare part, no one in office, no one bothered to see what I wanted. Left without speaking to anyone. Obviously don't need business .

Had a particularly difficult problem with my Mercedes. It was diagnosed several times and turned out to be 2 sensors out of tolerance. Excellent service at a very competitive price. Would highly recommend.

I went in because I had an engine warning light on and turbo lag. 2 previous mechanics had looked at my car and put the diagnostic tester on, and they both told me There was 2 problems with it. So when I went… to merlin auto services and said can I have my mass air flow sensor replaced, noel questioned why, so I told him. He said it would be rare for it to be that , and likely to be a split pipe/hose. BANG ON. cant fault knowledge and work quality. Thank you team
