Question about 2001 Audi TT

2 Answers

I have a 2003 turbo charged audi tt with about 89000 miles on it. When started it idles very rough, the tack goes from 500 to about 1200 continuosly surging and will not settle into a smooth idle. The other problem is when accelerating the engine makes this high pitched squeeking noise and looses power, this does not happen all the time but has happend several times in the past week.

Clean the throttle body and reset the idle. Also check the O2 sensor. I am having the same problem with my 01 tt

A6 turbocharged. Whyu does it smoke when it covers a 120km per hour?


I am going to say 'blown turbo'. As I understand it, they needs replacing every few years. They are susceptible to heat and incredible revolutions. They have to be lubricated, the seals go, and you get smoke.

Hi I have a audi tt 2001 model 180 bhp turbo v 5 and I am having intermittent starting problems any ideas thanks


check for sure the batt and charging.that can cause lots off problem.
weak batt gifs weak spark charge chould be round 14.7 not 14.9
that toomuch also not good.check sparkplug wires and rotor,if needed,
to replace use original parts.check also pipes off the turbo.

I'm finding that you can buy Audi TT turbo charger kits if you'd like for your Audi TT to be turbo charged. -----------------------------------------------------------------------

Have audi tt, 02 reg, started billowing smoke from exhaust, had turbo replaced 1day later problem returned only worse


That is steam a sigh of a blown or leaking head gasket. For a quick fix can try a gasket sealer you put in the radiator. I do n ot like to do this , but money can be tight may get you by till you can have it fixed. Sorry for your troubles.

Removing turbo from audi tt 225 quattrro


Yep, it is possible to get turbo off without pulling engine. I had a TB break at 85000 miles and did the repair at home (2 bent exhaust valves, 1 intake valve). Getting the turbo disconnected from the exhaust manifold was the single toughest part of this repair. It is attached with 3 reduced head socket bolts (appear to made from stainless steel). Eventually had to drive out one of the bolts...

Need new Audi TT engine & want some advice...


look fo an accident damaged vehicle,the turbo alone is a fortune let alone a damaged engine.Unless you can find a old time mechanic that could rebuild you old engine.Another alternative is to use any voltswagon engine of the same type but from a different vehicle because as soon as you say TT up goes the price .Or buy a cheap banger like an old saturn or escort

I have 2002 audit quattro TT with 180k miles. When I do a normal acceleration the car surges and rpm drop but pick back up. If I accel hard it runs fine. Also at idle at times it varies 200 rpm like a


this sounds similar to a problem i had. as the rpm went over 2000 the engine would stop for a split second and then kick back in.
after a few days looking my garage finally found the problem was a faulty air mass meter.
this cost me £200 in total to be repaired.
