I had the owner on the phone saying, it's got another light staying on (ignition lamp).
Got it back and it had communication problems with alternator to PCM, found the problem was a corroded wire in the loom.
When this was fixed I decided to check DPF, found it at 95% soot.
I took it up the M1 until it decided to do a regen. I could see the vapouriser was powered on and soot level came down to 9% before it switched off.
So this van had a bad service history (old blocked fuel filter), mil on so no regen (145% soot), blocked up vapouriser and a broken wire on rear temperature sensor.
The charging fault is nothing to do with the initial problems but if not addressed would possibly cause yet another DPF non regen situation.
It's a good thing my customer trusts what I do because I could see this sort of thing could cause a lot of problems.
One other thing is I found IDS can prime the Vaporiser but not the early versions.
Nice to get to the bottom of things!
