Audi TT Mark 1 trick – Reset your throttle body

Quick trick here for Audi TT owners – when you drive your TT it learns about your driving habits and will adjust the throttle body accordingly; so if you’re a cautious driver it will not be so quick on the power when you want to drive hard all of a sudden. This sounds like a less-helpful feature but actually can help with your fuel economy.

So when you’re ready to get the best throttle response from your TT, simply wait until the car is cold, put your key in the ignition, turn until the dash lights are on then wait around 3 minutes – you may hear some clicking. After that just remove the keys and then you’re done! If you’ve not done this before you may notice the difference!

Not sure if it works on other Audi Models or the new Mark 2 TT… if readers know, please

UPDATE: This note on the TT Forum as to why this is good for some:

“there is no accelerator cable but everything is electronic. The accelerator pedal movement actually produces a variable voltage between 1 and 4volts approx which is read by the engine management system. The EMS then uses that information, plus info from many other sensors to determine spark timing, fuel injection timing/period and air flow volume into the engine, the latter being controlled by the real throttle – an air valve driven by an electric motor. Now if you use the car for lots of gentle driving in town, say, then you never get to the wide open throttle (WOT) stage, so the EMS makes the 1-4volt range of the pedal equal 0 – 75% of throttle movement…. makes pedal more ‘sensitive’ and is better for fine adjustment in traffic … TBR doesn’t actually change anything mechanical – it just tells EMS to reset and recalibrate the throttle so that pedal right down “

  1. This is unbelievable but I think it’s true.
    I’ve noticed the car was quick a while back when I wanted to enjoy the ride. But later on it was a little lazy. Now I know why.

  2. Nice Thanks…

    Some Advice please?.

    Rev counter not working and clocks have been change by the Audi main dealer.

    Any help would be appreciated.

    Kind regards


  3. Rev counter not working could either be a loose cable, but I have seen this before with dashpod failures too – suggest socialising on the TT Forum if you haven’t already… or you could buy one of those CarMD devices to see what fault codes are happening…. but new dashpod… could be under warranty or 600 nicker..

  4. Thanks Paul, its an Audi TT as the forum users could only advise as the car isn’t there in front of them.

    The blokes now sold the TT so doesn’t matter anymore but thanks all the same 🙂

  5. Yes it does. I have done it countless times to know it does. This is a common technique for the Mk1 to reset the throttle body.

    What’s the symptom to make you believe otherwise?

  6. Hi Paul my audi tt is idling like lumpy, i have charged the coil sticks and plugs, M A F , still the same any help please

  7. You’ve listed all the components I would check… I cant remember if there’s a fuel filter to check , but at this point check it for fault codes and take it to a mechanic
