Hi I'm new to this forum.

My DSG tranny in my '06 Audi A3 2.0TDi (BKD engine):

a) sometimes slips on low gears between 900 to 2000rpm :( . in higher gears or when cruising, the DSG seems to be fine.

b) on idle I hear a slight grinding noise coming from the tranny. this noise starts to sound like a slipping belt when in gear or in "D".

e) i cant find any "fault codes" in my DSG tranny when i plug my VAGCOM.

could this be a faulty Dual Mass Flywheel???

Thanks in advance for the HELP!

Manny

It is possible. No way to know without having someone inspect it. But the slips on low gears doesn't sound like a bad dual mass flywheel. Bad flywheels don't really slip for no reasons, there is another reason its slipping.

It could be a bad valve body that controls the DMF. I could see a bad solenoid causing fluid going where it shoudn't be and causing slipping and the slipping belt noise.

Hi Grizzly thanks for your input.

Question: would it still be possible that my a valve body is faulty without it showing in my VAGCOM?

Here is something i just read at Myturbodiesel.com FAQ's:

http://www.myturbodiesel.com/1000q/dsg_faq.htm

The DMF is a Dual Mass Flywheel. The advantage of a DMF is smoother power delivery and less noise, vibration, harshness. But because it's two parts instead of one, it can fail. A slipping belt, soft grinding, or rattling at idle noise may be indicative of a failing DMF. There have been enough DMF failures to take notice. ....

Finally brought down the DSG today. I discovered that the circlip holding the outer clutch rings were off! So the outer clutch disc rings were out of place! Luckily the tranny housing was undamaged and we just re-installed the circlips. Waiting for the DSG fluid and Filter. Hope this works!
