Good evening guys, I’m hoping somebody can point me in the right direction here I am a bit of a novice when it comes to the latest technology of cars being of the ageing generation lol, my engine management light has come on on my Audi A4 2L TDI (B9) 2017 45.000 Miles When I run the scan with my basic OBD scanner, it brings up the above error code, now the car performs fine it doesn’t do much in terms of mileage probably 12 to 20 miles per day but every other weekend it does an 80 mile round-trip which may not be sufficient for the error its bringing up, I’m not 100% sure, hence why I’m asking you folks in the know, I’ve had the car just over 2 1/2 years and I’ve only had to do a driving re-gen twice in that time I keep it regularly topped up with ad-blue etc also don’t use cheap grades of fuel, but to cut along storey short, I have managed to turn the engine management light off once and it’s been about 10 days and my wife was out in it today and it’s come back on now. I have had a little scout around on the Internet, but it’s all new to me. Can anybody shed any light on it for me please? And if there’s any information that you need I shall be only too glad to pass this on.. Thank you all in advance for any advice Paul

Hi from many years of experience this is a wise choice you have made, personally I would have left the review, trouble is not many of the positive posts will admit something went wrong at a later date as for them its embarrassing to admit they got it wrong and spent hard earned £££££ to get it wrong, your car is plenty powerful enough, and a word to the wise insurance companies when faced with a total loss with a performance car will have the ECU analysed to check the mapping and if its not standard and undeclared as a modification they will walk away, leaving you with a law suit from the other parties insurance. Steve.

The points made are obviously correct. I won't be remapping my car. The point still remains though about plenty of good reviews for remapping services. I was tempted to leave a review when my turbo decided to implode to add balance to the overwhelming positive reviews.

Thanks for the update peoples

Hi I would have thought your prior experiences would raise a flag about this enterprise, the Turbos fail because the remap strains engine components to a higher level than they were designed to take especially on performance cars which have an even lower built in reliability factor than the standard model, BUT on a performance vehicle like the S3 the parts for a regular problem are eyewatering so imagine a full rebuild of the heads and timing chain system at about 40k five grand plus, they don't develop these cars and leave loads of room for some Herbert with a dark web program to make themselves rich.
