Audi A4 1.8 - Turbo Lag?
Hi,
I've recently purchased an used A4 1.8T quattro Avant (2002). I've
noticed that if you put your foot down whilst in second and I guess at
about 1700 rpm it'll start accelerating and then there'll be a pause
(which feels a bit like a lurch) then it'll carry on accelerating. Not
having had/driven a turbo before I was wondering whether this is
"turbo lag" or should I be concerned abut this? It doesn't seem to do
it if you're more progressive with acceleration and I've only noticed
it in second and third.
Thanks
Bob

That's normal. The turbo doesn't really kick in until above 2K rpm.
You really shouldn't be accelerating hard at such low rpm like you do.
You're just lugging the engine and it doesn't do any good. The real fun
starts above 3k rpm. If you're at 3K rpm and floor the gas pedal,
you'll notice that there is very little lag.

Does not sound like Turbo lag to me. You should not get a pause just a kick
when the turbo starts to spin up. To get the 1.8T to shift the only ay is
to keep it above 3000 RPM.

That sounds like a faulty Air flow meter like the diesels have.
It's pretty much the same symptom.
Do you have low mpg as well?
I'd believe that turbo engines are generally sensitive to wrong AFM
signals, no matter if it's a diesel or a petrol engine. If it gets the
wrong air flow reported, the control box just will not pour in
sufficient fuel.
Maybe worth checking.
