Any ideas appreciated.
I have a 2005 passat tdi. 203,000 miles. Recently it has been hard to start in the the morning and after it has sat for some time. Outdoor Temps have ranged from 0- 68F.
Once I get it running it randomly "bucks". it's kind of like a misfire some are worse than others, it happens at all speeds and even when it's in park. Things I've recently checked or changed related or unrelated are below:
Torque converter at 197,000
timing belt water pump etc.
fuel filter x2
gaskets for tandem pump, valve cover, oil cooler.
things I've checked over:
boost hoses
wiring connections to injector harness
cam (no signs of wear)
lift pump working
replaced maf to no avail
injector cleaner.
also I've checked it on a VagCom. there are no codes and all of the numbers seem to be correct.
I've also scavenged the forums extensively and have not seenthis exact issue discussed AFAIK.
Thanks in advance for any help!!
