Hello!
Here is the quick and dirty on what my car (2003 Jetta, manual, stock) is doing:
After sitting: Cranks too much and coughs some white smoke every time. Temp doesnt matter. First drive it starts off fine, does well in first gear and below 2400rpm and easy driving in the lower gears. Then, when I can open it up on the highway, it coughs up more white smoke when getting on the throttle at 2200-2600 rpms, lugs badly, loses acceleration, actually makes a sound from the engine compartment, and then passes the smoke like a kidney stone, and from there on out drives and responds just like a TDi should. Snappy, responsive, no issues whatsoever. It's like it has to do this thing once every drive and then it's cool. I only drive it 15 miles to work and back so I don't get stranded, not sure how it would fare on a longer trip.
It will be good to go until it sits again, then repeat this process.
Here is what I have done to it. All within the last 1,000 miles while trying to figure out this issue. Bought it as a project car, it had issues when I got it. Nothing seemed terminal.
Replaced timing belt, water pump, pulleys, etc
VAG COM Timing set
New MAF
New coolant temp sensor
New injector nozzles, calibrated by KermaTDI
Replaced the IP with one from a wrecked tdi. Absolutely no difference, problem is not in the IP!!!
Tested glow plug resistance - all at 1.2ohm
Cleaned the intake and EGR
Tried another EGR off a parts car, no difference
I am almost out of ideas. Help! I'm not the greatest mechanic so I probably missed something or skipped a diagnosis step.
Thanks!
