<br>I have been dealing with vibrations when my MKIV tiptronic Jetta's engine is cold.<p>The vibrations that I'm experiencing are listed below after a cold start, happens chronically:<p>- Reverse (Almost always apparent when the engine is cold, but once you are in 1st gear and give it a little gas the vibration goes away)<p>- Idling (it occasionaly happens in park, and sometimes just goes away as the idle settles down...never happens when engine is warm)<p>- After Initial "take-off" (goes away and doesn't come back until engine is cold again)<p>- As might be expected, the problem gets worse in the winter months.<p>- One time the vibration was so bad the engine just stalled on me & had to turn it back on again (It displayed a check engine light briefly then went away) - This was months ago and hasn't happened since.<p><br>I have been told this may be an engine mount problem. If anyone has input on how I can tell if this is true without lifting the engine off & seeing if a mount is worn, I am all ears. I doubt worn engine mounts would make my engine stall out, but It definitely could be part of the problem.<p>I have recently (after stall problem) been to a shop where:<br>- Flushed all fluids (brakes, trans, power steering, etc.)<br>- had the Mass Air Flow sensor MAF cleaned/checked<p>After the service, I didn't have any problems for a few days, then it started happening again. One other note from the service, my trans fluid was almost black, though at 85K miles I'm not sure it was ever changed.<p>Thanks for your wise VW knowledge and reading my long post!
