GSDMAN999 Posted January 15, 2008 Share Posted January 15, 2008 Hi I am writing this on behalf of a pal who owns an 02 TD4. Recently he has changed the tank fuel pump. He disconnected the battery first and carried out the job himself. Now, after succesfully installing the pump, engine starts fine and drives good. However, there are no instruments in the binnacle working at all!!? Tried locking the doors and giving time wait to see if, but still the same. Taken the ECU plugs off and refitted them exactly but still nothing?? any ideas?? Most appreciated TiA Quote Link to comment Share on other sites More sharing options...
BogMonster Posted January 15, 2008 Share Posted January 15, 2008 I think the Td4 instrument pack communicates with everything else on a network like many modern vehicles. I guess it has lost the signal somewhere, may be time for a visit to somebody with a diagnostic computer. You could try disconnecting the battery and leaving it overnight but other than that I don't know. I think it is probably coincidence though, no reason why disconnecting the battery should do that!

Ally V8 Posted January 15, 2008 Share Posted January 15, 2008 Does the car suffer any water ingress problems ? Quote Link to comment Share on other sites More sharing options...

Ally V8 Posted January 15, 2008 Share Posted January 15, 2008 Blimey - one of the few then ! If it still wont come back to life then first off its a feeds and earth session with a multimeter,(assuming all fuses are OK) If this brings nothing then a Testbook session to see if you can force any outputs.Then its repair/replace the instrument pack.

jules Posted January 16, 2008 Share Posted January 16, 2008 I've had something similar but it was due to a trapped section of wiring harness chaffing a load or wires but that was in the engine and it was the head lights that's wiring was trapped causing problems. are you shore you haven't trapped some wires around the fuel tank area.
