Thanks again for this site, very educational, thanks for sharing your knowledge.

I had this same problem for a year and half and have been meaning to get round to fixing it but have only been using the van on local roads. I tried fuel filter and then read this article went straight to mercedes and paid £52 for a sensor and it’s cured it . thankyou

Great writeup!

Hi Steve! I must say that this is the first page I have found that’s giving straight answers about the diagnostics of mb. I’m wondering if you would know about a tool for my car, it’s an v-class -99 220 cdi w638 (38 pin). Im about to get the Autel MD808 Pro but i get different answers from the seller’s about the compatibility, my primary need is to read/erase codes and get rid of the service lamp.
Best regards

thanks for great info. helped alot.

Super good tutorial on this pain in the butt repair!

Thanks for yet another informative and helpful post. I recently had a problem which was presenting itself as a glow-plug issue – the ‘wait to start’/glow plug light on the dash wouldn’t go out, engine wouldn’t start. The problem was intermittent (80/20) but we were sometimes in some remote, extremely cold locations (e.g. Switzerland in February), so glow plugs seemed a reasonable diagnosis.
Finally got to a MB dealer in Zurich who diagnosed the fuse box as the source of the problem. Easiest course of action since we were pushed for time and far from home was to replace it with a new one. Cost 300CHF – considering everything is so much more expensive in Switzerland, I had feared it would cost more. Being a dealership, they gave me the old box: I plan to use this thread to see if I can resurrect the old box.

This is the best write up I have ever read and I am extremely grateful for all the great advice. Thanks so much, how do I join the club…

Hi again.
Paul here with an update on the 2006 sprinter no start.
Well it’s been 15 months since the Sprinter refused to start. Thank goodness I had the old ‘W’ reg one. That old sprinter now needs lots of welding so back to getting the 2006 started.

Update.
Took the injectors to local specialist for testing. Could not test as all injectors ‘contaminated’ £5.00 each for looking.
Bought 3 injectors of ebay (one had been sold already) fitted them, primed the fuel lines, bit of diesel in the intake manifold!!!!!! It started. Rough running but put that down to the odd injector used to make up the 4. Used clean drum of fuel to avoid possible rubbish in the old tank.
Drove it from farmers field to his workshop.
Stripped the front bodywork to get to all the bits needed. Started it again and drove it into yard to power wash. Started again (roughly) but started, and driven back into workshop.
Stripped out all the injectors, fitted new seals and stretch bolts. Bought a refurbed injector £112.00 and fitted that.

No start.
Tried everything .
Talking to a friend about an Iveco van he had about possible purchase and he said it had taken 7 months to get his running. It was a faulty wiring loom to the injectors on top of the engine. Replaced with a S/H one and it started.
So back to the 2006 Sprinter. Stripped out the old injector wiring loom and rewired the cables to the injectors. All soldered joints and shrink wrapped.
Van tries to start but still no luck. Wondered if I have the location of the injectors wrong. I did take care but may have mis read the wiring colours due to all the black muck around them
From the front cylinder the leads seem to have these tracer colours on the old wires.
1 Green
2 Brown
3 Red
4 Yellow.

I’ve tried to find a wiring diagram on the net but it’s a needle in a haystack. Any help or suggestions would be much appreciated.

Cheers

Paul
