With over 30 years of electrical knowledge and all oem dealer diagnostics, I can accurately pinpoint your problem.
Too often I get vehicles that have been mapped elsewhere and have pending faults, in limp mode or just not right.
One of the things I do is to guarantee all work we do. So from deleting permanently fault codes to adblue, dpf, egr and stage 1 maps is fix your car.
If your vehicle has gone to limp and your check engine light has come on then usually you would go to your local mechanic. Clearing the fault codes will clear the engine check light but yes, it might and usually does come back on. Don’t worry as I can usually fix your car the same day, roughly from an hour depending on what model, etc
I would also like to point out that servicing is crucial in any modern cars and it’s important to regularly check your oil level, at least once a week. If notice the oil level is rising or above the top full mark on the dipstick then chances are your dpf filter has a problem and as your
and as your car regenerates unburned fuel that was supposed to go through exhaust dpf filter now runs down the liners between pistons and mixes with the engine oil.
