            Good luck with that, you'll not find one.

            What electrical problems and which loom? There's 2 under the bonnet and a few sub looms as well.

                That little bit of info helps - not an engine bay wiring issue at all by the sounds of it..

                Now maybe a few more clues.... what was van originally, what engine has it been converted too? Was the loom swapped, clocks?

                The led lights - oil/temp/charge/glowplug ??? which ones are lit up?

                Are there wires to the sensors on the engine?

                The rev counter and LED lights could well be explained by the loom to the alternator not being plugged in?

                The speedo....not related.

                  Wiring gremilns on a TDI conversion?

                  Is your loom still running the big round multi-plug on the engine side of the harness? (Front of the block, right hand side?). If this isn't fully 'home' and earthed you'll get no end of issues...

                  Get some pics up of your messy wires - just for a laugh! [emoji16][emoji106]

                          Not sure vagcom will be much help here - just needs a methodical going through the wiring and eliminating possible faults systematically.

                          I can send you a wiring guide and help you read it if required.

                          Do you own a multimeter or continuity checker?

                          Start by telling us what wires are floating around the bay and what wires are connected to what sensor - also the connections on the back of the alt.

                          Photos would help. a lot.
