Re: New Noise - Engine noise while in Drive - '02 1.8T Quattro
 

Thanks Tony. I am also puzzled. Incidentally, MIL illuminated as I
was driving home last night. Performance (acceleration) seems "soft" -
noise is still occuring.

Re: New Noise - Engine noise while in Drive - '02 1.8T Quattro
 

My 1.8TQM with APR 1 bar chip had another issue due to the wast gate actuator on
the K03 Turbo failing. When that happens you loose boost >> loss of power :-( It
is typical to hear a rattling in mid range engine RPM. I wouldn't call the sound
a buzzing but more of a high pitched rattle.

You can test this by looking beside the engine and above the turbo to see a
shiny rod running parallel to the length of the engine. It is quite difficult to
see or reach but can be done (when engine is cool). If you can reach it try to
move it with a stick to see if it is loose. If it is this may be your problem.
The K03 turbos have this happen quite often at 60 - 100 K. Fix is to either
replace the turbo or the just the waste gate assy can be found for around $200.
Labor will be three or four hours. DIY is possible but a bit challenging.

If this is your problem, you could also think of it as an opportunity to justify
a K04 / chip upgrade for more smiles.

Re: New Noise - Engine noise while in Drive - '02 1.8T Quattro
 

Thanks Tony,

I am bringing it in tonight. I will have them scan the ECU (I think
that is what it is referred to) to get the code (since the MIL is
illuminated there should be a problem code associated with this). I
will also mention checking the Waste Gate Actuator.

Incidentally, I have never worked on cars (other than a 1980 Chevy
Citation) so a lot of the terms that are used are a little foreign to
me.

Thanks for the tip.

Cheers
