    Hi guys

    I recently changed (forced due to someone driving into it) my car from a 2001 A3 1.8T Quattro to a 2006 A3 2.0T and have my doubts as to whether the new car is driving as it should. In the 1.8T booting it in 2nd would result in being pleasantly pressed back in my seat and very rapid accelleration, however doing the same in the new A3 is not like this at all, which I am very surprised at given that the 2.0T has more power than the other. It doesnt really feel like a turbo car at all. I have had it checked over by my usual Audi specialist and the only issue found was a faulty coil pack that was on its way out. Since the fix there has been no change in driving characteristics.

    So my question is: does this sound normal (just different driving characteristics to the nature of the engine) or could it have some underlying issues that are not immediately obvious?

    Thanks in advance.

    check for your MAF mate, maf wont come up on vagcom as you need to log it while on a run to see what its pulling in so it could be a maf or an N75. both easy fixes, MAF is around £100 and not sure about N75 but maybe cheaper maybe not who knows. try and find someone around your way who has vagcom and is competent with it so they can check for you, other way of checking is unpluggin the maf and then see how it runs.

    I suspect its a weight thing, the 8p is so loaded up with junk its never going to pull like a lot of early cars. I think i read somewhere that the 250bhp 3200cc 8P has roughly the same power weight ratio as a Mk3 16v 2000cc 140bhp Golf give or take a few bhp :)

    on the contrary I've just bought an 07 2.0T and love it! I realise that I've been driving a 140 TDi for the past year but have had an Impreza STi, REVO'd S3, REVO'd Leon Cupra R etc before and I'm contemplation not mapping the 2.0T. Maybe I'm just getting old :laugh:

    That engine is superb remapped, then it DOES feel pretty quick.

    I went from a 2003 1.8T Golf GTi 180bhp to my A3 and the engine is a lazy engine compared to the 1.8T 20v lump. Once you change your driving style a learn to hold the gears further up the rev range then they do shift, but I know what the OP means by the lack of push back in the seat... Just a different style of engine as time goes on...

    I found the 20T super responsive for a Turbo lump, went from a VR6 to 18T to VTEC to 2.0 T, and reckon the 2.0 T was the best comprimise.
    Remap is your friend here.

    I had a A3 2.0T Quattro for a while as a loan car and i was not taken aback with its performance either !!! I averaged 26 MPG with it and for that i would expect blistering performance, think i will stick to the 1.4T and 45 MPG, Quattro takes a bit away but it does not have the get up and go that other 2.0 Turbo's have.
    Once had a drive of an Audi W12 in a Bentley now that did frighten at a tad over 600 HP, felt like i was in a Eurofighter.......................

    You should notice the difference - I went from a 2000 1.8 TT 225 Quattro to the 2.0 TFSI Quattro and thought it a smoother drive and as quick. If you're a bit underwhelmed get it Bluefined and I promise you won't feel the same after a few days - Fuel economy even goes up. (a bit)

    what are the best maps these days for the 2.0T obviously for my S4 there are only 2 people who i trust and that is MRC and Rich(Viper) so do you boys have the luxury of having people like that around who can custom map you cars or is it just generic maps from the likes of REVO etc?

    the 2.0T is meant to be a very progressive engine. i don't get a shove in the back either, but my car certainly does shift. slow is certainly not a word i'd use to describe it

    Thanks for all your responses. I think I just need to get used to the different driving characteristics by the sounds of it, although I will get the MAF investigated just in case that is playing up.

    I would have thought diverter valve would be a good place to start as they are known for going and make the car feel non-responsive on the boost front,there is replacement one done by the factory as the old seal used to rip apart

    No shove in the back here either, but I know that I'm accelerating fast because the cars that I could once see through my windscreen always end up in my rear view mirror.

    The A3 is very good at disguising to the driver how fast it is really going. Sit in the passenger seat and get a mate to take you for a little blast in it, and then see if it feels any quicker. Bet it will.

    The easiest and most concrete way to see if your car is performing/accelerating as it should do is to do a quick 0-60 test on a dry day.
    If it takes any longer than 7 to 7.5 seconds then there probably is something not quite right. (if it's DSG then you should hit 60mpg in a fraction under 7 secs everytime).

    I still think for peace of mind i would check the diverter as this is before they did the revised one,obviously if it has gone its holding no boost
