benthegardener Posted June 16, 2014 Share Posted June 16, 2014 I have recently bought a TD5 pick up which seems to have a few electrical gremlins. Speedo not working at all. milage doesn't change, doesn't light up at night, no speed indicated Reverse, and interior light not working. But wierdest of all is the temp gauge which starts in the middle, at the 12 o'clock position, then as the engine runs for a bit, and gets up to temp, the gauge goes down into the blue. I also have a lumpy running engine at low revs, so does the ECU run off the same temp sensor and if so will that think the temp is high and then lowering, which would trick it into misfuelling for the engine temperature. Or will the ECU know the temperature properly off a different sensor? Any ideas, gratefully received Quote Link to comment Share on other sites More sharing options...
landy andy. Posted June 16, 2014 Share Posted June 16, 2014 I think temp gauge reading like that is a sign of Disco ECU fitted, not a Defender one. Andy Quote Link to comment Share on other sites More sharing options...
benthegardener Posted June 16, 2014 Author Share Posted June 16, 2014 Ah that would make sense. The original ECU was stolen, so maybe a disco one fitted instead. Is there a way around it? I'm guessing yes change the ECU. Quote Link to comment Share on other sites More sharing options...
landy andy. Posted June 16, 2014 Share Posted June 16, 2014 Think the tuners can sort, or new ECU. Worth getting done properly as it's possible that you have many other issues caused by wrong/different ECU. Try chatting to Garry wood at Alive tuning. Very helpful chap, can sort by post.

benthegardener Posted June 24, 2014 Author Share Posted June 24, 2014 Well finally had 2 minutes to get onto this again today after speaking to alive last week. Having removed ECU, it appears I have a Disco TD5 Auto ECU fitted. Good call Landy Andy. Changing the ECU is the only option apparently. That first then onto the next job..... Thanks for advice anyway. Quote Link to comment Share on other sites More sharing options...
