• Ford Galaxy Zetec, petrol, 2009 - Can throttle box problem damage ecu? 19 Apr 2016 (Forum)
  Hello I had engine malfunction messages so took car to the Ford dealer. They said needs new ecu, £1450!. 20 mins after adding new ecu they tell me that new code indicated needs new throttle box, £450! Now should the diagnostic test have shown up the faulty throttle box first and had that been corrected would the ecu have been OK and not needed to be replaced?

• Carlton and ECU problem! 6 Nov 2002 (Forum)
  I own a good automatic '90 Vauxhall Carton 2ltr with genuine 48k on the clock. Thought ECU was faulty but jumping diagnostic output plug reveals a stream of code 12s - code for ECU initialisation (with engine running) and code 12s plus 31s with engine off (31 = no crank rpm!)so in theory - ECU seems OK!

  Can anyone advise here please. I need to do an ECU swap on a clio 1.5dci (delphi)   I can download the old units data with clip and upload to the new unit but this does not transfer the immo coding so it won't start.

• Hyundai Santa Fe - ecu 15 Mar 2014 (Forum)
  my timing belt adjuster was loose so i put the car in to have a new one fitted. 8 weeks later and (after driving the car into the garage) the list of repairs are.... 4 new valves new camshaft ecu re programmed..... Apparently, as i turned the ignition off, the timing belt must have slipped and caused all of the above?   Any thoughts on how (especially the ecu) this is possible as im baffled and skint

• Daewoo Lanos (1997 - 2002 ) - 08 1.4 resetting ECU 12 Feb 2010 (Forum)
  ive seen on other motoring fora a tendency to reset the cars ECU when rough running is present....i think the proceedure is to disconnect the battery for 5 mins put the ignition in the on position,then off and then re connect the battery...then the ECU re learns all the settings and timing etc etc........does it actually work?

• Peugeot 306 (1993 - 2001) - 99 1.6 OBD version ECU in an XTB 1 Jul 2008 (Forum)
  I have a Peugeot XTB 1.6 1999 modell . Does anybody know which OBD version the ECU is using for this model? (OBDII or earlier..) The plug is J1962 , but a OBDII/EOBD reader I tried ,could not communicate with the ECU , so maybe the french has got their own protocols for pre 2000 modells, does anybody know ?
• self learning ecu on HDi 21 Jan 2007 (Forum)
  Can anyone tell me if a 2001 306 hdi would have an ecu that learns the drivers style? I was wondering whether it is possible to increase mpg by 'resetting' the ecu? I have just replaced the throttle position sensor too so would it learn about how the car is driven over time or is there a way of kind of clearing the data to start from scratch forgive me if this is a daft and/or vaugue question cheers
