I have a quattro tiptronic 1.8t

I'm thinking I have bad tranny mounts. IT is the tiptronic so therefore there would be 2 tranny mounts of course. But here's my symptoms...

Idles Rough/Shakes when in drive/reverse Idles smooth when in park/neutral

From what I can tell the car seems to drive perfectly fine no problems. no clunking no rough running or vibrations.

I popped the hood and looked at the engine while someone but it in park reverse/drive ect, and I noticed that engine did indeed tilt forward and backward when shifting reverse/ drive. Is this normal?? it looked like it would move about 1/2 inch in both directions at the most. No side to side movement so i'm assuming motor mounts are all good and well.

Any thoughts?

 

Sir, it could also be transmission issues , call Ric at level 10 anytime for free advice, 973-827-1000

 

Check the snub mount to the radiator support, those rubber bushings go to pot pretty regularly. I would also take off your belly pan at look at both motor mounts, they are a hydraulic design. If there is a dried up red fluid on the bottom of the mounts they need to be replaced, i would actually think that the transmission mounts are fine.

 

Yea i agree with Auditech79..... They are hydraulic.... You would see fluid coming out of them.

The nose mount does go bad, but the motor moves no matter what when shifting and driving. If you don't feel any knocks or bangs, something more violent than just movement. Sounds like your just being paranoid

 

Yes I'm very over analytical. I'm used to v8 engines, 4 cylinder idle is totally new to me

 

Makes you miss the smooth operation of a V8 huh?

 

lol yes indeed. since I was 16 I had never owned a 4 cylinder car. I've always had small block v8s, two camaros, two trucks, and a jeep.

I deff don't miss the weekly 80 dollar fill ups though. maybe not so much on the camaros but the other 3 yes.
