Hi everyone,
Recently I've noticed that my '05 golf tdi with ~126k miles has a rough idle while the car is cold. As soon as the car approaches operating temperature the idle smooths out. When the car is idling rough, not only does the car feel rough (in terms of transmitted vibration) but the engine speed will also oscillate between ~900 and ~1000 rpm.
Within the last ~5k miles I have performed the following maintenance (admittedly not all is related to the problem):
- oil and filter
- air filter
- fuel filter
- cleaned intake
- strut bearings, tires, alignment
Within the past ~25k miles:
- alternator pulley
- belt tensioner and belt
- timing belt, waterpump, etc.
I am not very well versed in the world of the diesel, so I could use some help in sorting this out. I recently received a glow plug recall notice from VW, and I have not yet had the chance to drop the car off for the service. Could the glow plugs contribute to this issue or are they not a factor after the motor is initially cranked? Also, I do not use any sort of fuel additive... is there something I should be using that could help remedy this issue?
I would appreciate any help on this topic. I apologize if I've omitted any valuable information or if any of my questions are extremely basic. I do not have a VAG-COM but I may be able to track one down if it is absolutely necessary to help troubleshoot.
Thanks,
Lee
