Hello!I own a 2000 TDI Passat . The engine code is AJM and it's 116 BHP , pumpe duse type.In november I changed the hydraulic cam lifters and the timing belt kit and since then the car barely starts .
The day before I changed these parts the car were strting normally only problem was that there was idle fluctuations betwen 700 - 1000 rpm for few seconds while the cam lifters were making some noise till the oil pressure were to fill them well.
Since then every cold morning is a hell for this car .I crank the engine for 1 minute to start .
I have a list of possible causes that I have checked:
Mechanical tuning for Pump-injector - checked
Engine advance timing - double checked with my VAG COM and another Delphi tester (stays at 0 -0.5 degrees)
All filters - new MAN filters (fuel, oil, air)
Glow plugs - 4 new BERU
All actuators checked with vag-com , including glow plug relays
Electric fuel pump - my car doesn't have one
Injectors correction - betwen + - 0.8 each
coolant temp sensor - put a new one (just in case)
MAF sensor - brand new
Battery - Bosch Silver6 moths old
No error on VAG COM
Before I do this the engine were starting quickly.
Here are 2 youtube clips that I made (inside the car and outside at the same time).
The problem is that the colder is the engine the harder it starts .When is a spring temperature (4-5 degrees in the morning) I crank it for 2 seconds.At - 1 I crank it for 5-7 seconds and if tere were 10 degrees I cranked for 1 minute . At -17 degrees I had to pull the car to start.Is not about how long the engine stays . It seems to be related how colder the engine gets gets.Did I forgot to do somethig during the camlifter change?
