• Volkswagen Golf IV (1998 - 2004) - 99 1.9TDi turbo not working, could it be the ECU? 26 Feb 2009 (Forum)
  My local garage had a look and couldn't see anything 'straightforward' wrong that they could fix straight away. They said they would need to replace the whole thing (expensive). They did ask about the new ECU I had fitted two years ago at a VW dealership. They said to check that they put in the turbo one, as if they didn't then there wouldn't be a signal to tell the turbo to work. could this be right? I called VW and they said the model they put in (WO38 906012 L) was the right one.
• Vectra ECU Fault 22 Aug 2005 (Forum)
  The car was sometimes relunctant to start if on a slight incline but would eventually start. Recently the ECU light has come on and the engine has went into emergency / limp home mode. I toook it to an independent Vaux specialist, who ran tech 2 on it, but could find no real reason for the fault. He suggested replacing the crankshaft sensor which was done but this hasn't rectifired the error as when I go above 3K revs the light comes on and the limp home mode arrives!
• GM ECU Fault Codes-Life-Span? 12 Jun 2003 (Forum)
  I thought that all fault codes were lost when the battery is disconnected - in this case it appears that the error message was held in the ECU memory, even without battery power, until a correct signal was received from the sensor. Can anyone clarify this?

• Honda Jazz 2008 EX - Changing battery 25 Apr 2016 (Forum)
    I have rung a couple of places for battery prices and some tell me that I will need to set up a 'trickle charge' to the leads as I change the battery as it will mess with the ECU, radio and clock settings - the clock and the radio I am fine with the ECU ???, and others tell me that it is a simple "on and off" swap. Could anyone set me straight with this please?
• VW Golf TDi Mk4 - Convenience unit 30 Apr 2013 (Forum)
  I have been told that the "convenience unit" has blown , i believe that its attatched to the vehicle's ecu. Does it just plug in, do i have to have the ECU reprogrammed after it's been replaced? Do i need to remove all of the dashboard in order to get to it?   Many thanks

• Vauxhall Monterey ABS Fault Codes 29 Sep 2004 (Forum)
  Hello Folks, I suspect that it's a "yes", but does the ABS ECU store the codes? I have an intermittant sensor fault. My Vx franchise thought that the fault might need to be present when the ECU is read. Does anyone know of a gadget that reads them? I suspect that it's "Isuzu Only".

• Vauxhall Astra G Petrol (1998 - 2004) - 01 1.6 - cutting out after startup 3 Jun 2008 (Forum)
  If I started it and revvved it then it would be fine. The garage said they could not get it to stall and there were no error codes on the ECU. They then proceeded to upgrade the ECU software from v5 to v6. I went to the garage to pick it up. It started fine. As I had to fit the child car seat the engine idled for a while before I drove.
• Peugeot 406 - Immobilizer light on, car fails to start 12 Apr 2014 (Forum)
  I can hear the fuel pump priming, the engine turns over but it won't start because the injectors are disabled by the ecu. I have replaced the complete set of identical ECU, BSI unit and lock and key with transponder and no joy, exactly the same symptoms. ECU diagnostics check suggested the Comm 2000 unit could be at fault.
• vx corsa 2005 1.2SXI twinport - none start also no lights 5 May 2012 (Forum)

• 2 litre zetec in mk2 fiesta no spark 7 Aug 2011 (Forum)
  i have a mk2 xr2 to which i have fitted a 2litre zetec from a mk1 mondeo along with its engine management loom and ecu, everything is finished but there is no spark at the plugs, i have tried another coil pack which has made no difference what i would like to know is what does the ecu rely on during cranking to fire the plug, is it simply the crank position sensor or or other sensors involved?
• Rover 200 (1995 - 1999) - 95 1.4 engine starts but cuts out after 1 second 8 Dec 2009 (Forum)
  I have tried the door key code many thousands of times but it does not work, so i bought a second hand ecu, immobiliser and key fob. I think the ecu may have been the wrong one as, although the immobiliser was no longer a problem, the engine will not start, the starter motor is engaging and engine doesn't sound like it should.
• Volkswagen Passat (2001 - 2005) - 02 1.9 diesel tdi turbo loss eng code avf 9 Jun 2009 (Forum)
  After starting engine solonoid valve actuates. This valve has a 2 pin feed red/white 12v feed. Earth return to ecu brown/yellow.

With ecu plug re attached and connecting multimeter across solonoid valve 2 pin plug ign on voltage at this point is only 9.8 volts any feed back greatly accepted
• Peugeot 306 (1993 - 2001) - 01 1.6 ECU lamp -how do you clear it? 9 Dec 2008 (Forum)
  The other day I put new battery in, took it for a spin but the positive terminal was loose so it brought up the ECU light as it juddered for a few moments. I reconnected pos terminal and car runs no problem I've tried disconnecting battery for 10 mins and reconnecting but the light stays on. Car is running perfectly and I don;t have time to take to dealers just to get light extinguished (I have recent diagnosis of serious illness and am currenly undergoing treatment).
• FIAT Punto (1994 - 1999) - 1998 1.2 no spark 2 Aug 2008 (Forum)
  He wrote on the breakdown report " live feed to coils and injectors no switching" He said it might be either the crank sensor or a relay or the ECU. He said to change the sensor first and if it doesnt work to do the relay and failing that, the ECU The fuel pump primes but there is no spark, my local (30 minute drive) scrapyard has the same model in but i have a mate who is an experianced mechanic says it is bound to be the ignition pack , saying the fuel wouldnt prime if ECU/crank sensor is faulty I dont realy want to buy the wrong bit/s for it obviously and i only have free car hire from AA till saturday lunchtime.If its the sensor or relay it would be handy (cheap).
