Chris 1971 Posted June 14, 2018 Posted June 14, 2018 Hi all, New to the forum, and new to Audis in general. I've recently bought a lovely 2012 B8.5 A4 Avant, TFSI 1.8 (170). S-Line, Black Edition, only 50k miles, great condition - very pleased with the car generally, but I am having a bit of an issue with the accelerator response, which is frankly poor, possibly even dangerous if you need to / like to move quickly. Most noticeable pulling out from a junction but it does happen overtaking too. Any 'kick' comes a long, long way down the press of the pedal, and even then it takes a hell of while to go. It's like I'm taking the car by surprise every time. When it does come, it's smooth and powerful - no complaints there. Doesn't feel like turbo lag - during the period of 'no response' (way more than a second I'd say, which is much too long for my liking) the rev counter doesn't flicker - so even the basic engine is not revving initially. I also drive a little 2015 fiesa zetec S ecoboost 125. Hate to say it, but the difference is night and day. Barely-perceptible turbo lag - pretty much away as soon as the pedal goes down. Yes - vast difference in weight and all that, but still - Audi v Fiesta? It's not all bad - cruising round where I live and around the town etc makes for a very easy comfortable drive. So what I'm kind of saying is it's very easy to drive it slowly.... (yes - exactly - you see my problem...) Some Googling results in a fair amount of similar complaints, with a 'Throttle Body Alignment / Throttle Reset etc etc' provided as a possible solution. So apparently (some?) Audis adapts to your driving style in terms of acceleration? and the 'reset' restores standard settings? Not sure how true all of this is. If it is, I'm not really sure of the benefits - seems obvious to me but surely, well, your driving style should determine how the car is driven - not the car itself?? Anyway - to cut to the chase - all instructions as to how to perform said reset / alignment don't seem to apply to my car (turn the key without starting the engine etc). So not even sure if it's an option for me. Is any of this true? Has anyone ever had this issue? Has anyone performed the 'reset', or otherwise rectified the issue? To be honest it's spoiling my enjoyment of an otherwise great car. If it's a fault, it's under warranty from the dealer I bought it from, but not even sure if it would be classed as a fault as it's quite a subjective issue. Any info / advice most gratefully received. Thanks, Chris.
