I have a 99.5 jetta that has been intermittently cutting out and stalling.
If I wait 20-30 min it will restart. Some time it doesn't die on the road if I keep the
Clutch ingaged in gear for 5-10 seconds while it's cutting out
It will then resume like nothings wrong. It's been getting more
Frequent. Use to start after about an hour of cruising but now it's
Doing it on short trips around town. The pump timing fluctuates
From about 54-68 and is not stable like my other 2 tdi's.
Could this be a sign of the injection pump going out. Is ther a way
To check the pump with vcds? No leaks on the pump.
Are these rebuildable? The fuel quanity runs at 3.4 at idle.

This is classic relay 109 symptoms. Take off the plastic knee panel under the steering column and look at the relay box. If relay 109 is black, replace it with updated relay 109 that is gray.

Relay

I think I rememeber replacing that relay a couple of years ago, But I'll check agian when my son gets home.
Is it normal for the timing value to flucuate + - 6 or 7.

Ground loop

Were are the main chassis ground. I like to rebond this connection just to be sure.
