Hi, this is my first post so please be gentle. I’ve had my 2002 1.4tdi (75) A2 for coming up to 6 years now and I’m very keen to make sure she’s around for another good few.
Unfortunately about 12 months ago she began developing an issue on cold start up. Basically one of two things happen.
1 - On turning the ignition the glow plug light comes on for 2-3 seconds before going out. On start up the engine will rough idle at about 1000 rpm (or just under). It feels and sounds like the engine is choking/panting and is about to cut out. If I give her some revs (around 2000 rpm) for about 10 seconds she’ll then dump a load of grey smoke out the exhaust. Following this she'll idle smoothly and run perfectly.
2 - On turning the ignition the glow plug light comes on for about 6-8 seconds before going out. On start up the engine will then idle at about 2000 rpm for about 3-4 seconds on its own before settling back to around 1000 rpm with a smooth idle and no grey smoke. She then runs perfectly.
The vast majority of the time scenario 1 happens. This is becoming increasingly annoying as I’m now regularly smoking out unsuspecting passersby, neighbours and work mates.
had her in a few different garages and so far tried the following:
- EGR valve cleaned in situ with aerosol based cleaner.
- Glow plugs replaced twice.
- Glow plug wiring loom checked.
- Glow plug relay checked
- Injectors removed and sent off for testing, refurbished and reinstalled.
- Injector loom checked.
Diagnostics have also been checked but I’m told that no fault codes are showing up.
Any advice or help would be really appreciated as I’m running out of ideas and getting fed up of spending money without seeing any improvement.
Thanks in advance, JT
