Well, thanks for a great forum for a start massive wealth of great info so congrats to the regulars for a start.
I've had an A2 for a while and love it as you probably can empathise, well after a long embarrassing story irrelevant to this, I've had to buy a new one, from a dealer, with 6 months warranty unlimited miles, awesome. 72k on clock.
All was/is well as no engine management lights come on and a round town test drive was great. On way home tho, at 4000 revs (mostly and most noticeably in 5th, other gears prob hide the problem) there's a massive flat spot, kinda like a limp mode but certainly an issue somewhere. Cant say if its a misfire or not.
Called the dealer and he doubts there even is an issue with no lights on and he swears blind he's vagcom trained and i believe he's genuine.
I've researched the forum a lot and my main theory would be the throttle body needing cleaning. I'm arming my self with as much info as poss to ascertain wether, when its in to Audi tomorrow, the issue is covered by warranty. Which as its not complete failure, i doubt it is (sceptical i know but i like surprises).
My theory of throttle body dirt or something is for this reason. When i open throttle (say half way) and take it up through revs (in 5th) I hit the flat spot every time around 4000 rpm. I can then give it a little wiggle (maybe 2-3cm back and forth) I can feel it clear and back on the power and can cruise right though 100mph (in theory obviously). I am NOT a boy racer before you presume lol. There is a definate point where something (injectors i'm guessing) kicks in.
No EML lights at all but I'm sceptical the dealer has somehow maybe used his vagcom to 'turn off' that sensor as to hide the problem from the ecu...?
When the ignition is first on, computer flashes OK straight away and one by one the lights on dashboard go out. This different to the start up procedure of my last fsi, which was a year younger (late 03 plate). That would run through first and then flash OK. Although, double pressing the left dashboard button/stick does start that procedure. This theory will be put to bed tomorrow i guess with a proper scan.
Also, the cars been run on unleaded nearly all its life. I've then put Super Unleaded in with a half dose of redex. Any thoughts about that?
I'm within my rights to resuse the car under sales of goods act but reluctant as hell as id be left waiting for a refund from him while having no car as such. nightmare!
Im sorry if seems vague and thanks for reading, any response is appreciated.
KNOWLEDGE IS POWER!
