Hi all, new to the Audi experience having just collected a 2007 convertible 2.0 TFSI. First impressions are... I love it... what a well put together car.
It has 130k miles on the clock with full service history in the book. It didn't have any other receipts or paperwork, but it starts, runs and goes really well. MOT history wasn't anything to worry about.
But, just one niggle. The engine is loud under load in second gear, from 1300-1800 rpm. the noise is virtually un detectable if I drive like a granny, but the slightest bit more right foot and there is the noise. Is a metallic high pitched rattle but not in the heat shield sense. Plus, if im down shifting into second gear, and the rpms are in that range, when I hit the bite point and the revs go up, there is the noise again for a fraction of a second while the engine speed matches the transmission. Im convinced I can also feel it through the clutch pedal.
I didn't pick it up on the test drive, because I was being a bit lead footed to give the car a good workout. When you get up through the gears quickly, the time spent in the "noisy band" is very small.
My intuition is telling me its transmission related, but I have never had a Turbo before, so it could be something to do with that, or the diverter valve? (but is it really at boost at such low, and increasing RPM's?)
I have googled the hell out of it, but none of the noises I have listened to on youtube sound like mine. Like I say it's only under load, in that specific RPM band so I can't replicate it on the driveway. Google takes me to engine mounts, diverter valve, DMF, etc..
The other thing to note (just in case its related) is the temp gauge is variable between 12oclock-ish and 10 o'clock ish. I haven't been able to determine any repeatable logic with driving conditions yet.
I have just put in a new air filter.
Any thoughts would be appreciated.
I'm so tempted to take it to Audi because they would definitely be able to hear it, and the car is under warranty from where I bought it, so best to check it now!
