• Vauxhall Vectra B facelift (1999 - 2002) - 00 2.0 ABS & TC light on all the time. No speedo 7 Oct 2009 (Forum)
  Hi All My W reg 2.0 Vectra has a problem which at first was intermittent and is now permanent .. the ABS and TC lights are permanently on and the speedo appears dead. A mechanic friend tried to communicate with the ABS ECU with a diagnostic box but got 'no communication'. I have done a few basic things like cleaning the front wheel sensors and checking the ABS fuse but problem still persists. Searching the web for this problem suggest that it most likely to be the ABS ECU.

• Vauxhall Vectra B facelift (1999 - 2002) - 00 1.6 ECU light on- starts "missing"at const foot 6 May 2009 (Forum)
  hi I have a vectra 2000 Model 1.6 engine Z16XE. Done only 70K I just bought the car and its ECU light started coming on. I have noticed that whenever this happens the care starts to miss at constant foot pressure (accelerator). It?s better at high revs and higher speeds. The Code retrieved is P0400 EGR valve redistribution.
• Toyota Corolla (1997 to 2002) - 1997 1332 Igniter problem 22 Mar 2009 (Forum)
  Anyway, having conducted the flash code retrieval (bridging TE1 and E1 in diagnostic port) the code 14 came up. This is "ignition No IGF signal to ECU for 4 consecutive IGT signal during engine running Open/short in IGF/IGT signal from igniter to ECU Igniter malfunction ECU" according to one site, but my question is does anyone know the location of the igniter on the 1332cc Corolla (its the newer 'bug eye' shape).
• Rover 75 (1999 - 2005) - 2003 2.0 Radiator fan 14 Oct 2008 (Forum)
  In normal driving the temperature seems OK with the needle in the middle (i.e. as pointing west on a compass). Earlier in the year I had the common 75 problem of a flooded ECU. The ECU was apparently OK when dried out (although the glow plug relay was corroded and had to be replaced). I am wondering if this may be the cause of the fan problem as I presume the fan operation is controlled by the ECU.
• Rover 400 (1995 - 1999) - 1999 1.4 ECU Advice 27 Aug 2008 (Forum)
  It's in being fixed just now but mechanic called me to say there's a problem with a switch related to the ECU which means a fan is not being triggered, so he's going to fit a new switch and hopes this will resolve it. He mentioned if this did not resolve it, I should constantly keep the blower on at setting 1, and constantly have the air con switched on.
• Ford Focus Idle Problem?? 22 Aug 2003 (Forum)
  I would appreciate any help, as i feel the dealer is guessing? Will it help by disconnecting the battery to make the ECU re learn its sensors? If so, what do i need to do to put the ECU in \'learn\' mode? How long does the battery need disconnecting? How should i drive it afterwards? Thanks for the anticipated help.
• am i being fleeced ??? 10 May 2003 (Forum)
  (I suppose hours three, four and five were good and didn`t need permission) They called me back about an hour and a half later to tell me it wasn`t the relay but the ecu would have to be replaced and I would be charged for the relay, six hours labour, the new ecu (which will take two days to arrive) and two hours to fit the new ecu. All this for a grand total of around £900 .
• Do we really need or want this level of complicati 6 Dec 2001 (Forum)
  Just been reading an article about the new BMW 7 series 6 speed auto transmission 6HP26 also known as "myTronic6." Quote from Vehicle Engineering and Design Nov2001. ?At the core is an ECU from Motorola?s PowerPC family. Each transmission produced at Saarbrucken goes through a battery of tests to establish its unique characteristics, which are then programmed into the chip, *creating a bespoke ECU for that specific transmission* . ?
• Fiat 500 sport - Engine Misfire 30 Sep 2016 (Forum)
  I've tried 2 different brands of coil packs, changed all the plug leads, new plugs, serviced the car new oil and sent the ecu away to be checked out which came back ok. But still i've got this mis firs problem which causes the ecu light to come on and the error is misfire cylinder 2.

  The car wont start aftter all the basic checks put it on a code reader which pointed to the cam sensor (in the pump) so i removed the fuel injection pump for testing this came back no faults fond. I then removed the ecu for testing this came bacck no faults found so is it possible to test the can-bus link between the ecu's

• Blanking of EGRs and insurance? 30 Nov 2009 (Forum)
  When they go wrong they cause problems and they are expensive, so people just blank them off completly. Vauxhall even have a mod where the dealer will disable the EGR function in the ECU for some engines, so it seems the dealers even support this mod. There is an otion in the Tech2 software which apparantly disables this part, on some I think the ECU automaticaly detects that its been blanked.

• Ford Mondeo III (2000 - 2007) - 01 1.8 Coolant temperature sensor 17 Jan 2009 (Forum)
  Does anyone know whether the Mk3 mondeo 1.8 petrol has two different coolant temperature sensors (one for the guage and one for the ECU) like the Mk2? I know there is one built into the thermostat housing, but not sure whether this is for guage, ECU or both. The car can be quite difficult to start and lumpy when cold, but fine when warmed up.

• No fault with tyre pressure sensor 4 Jul 2007 (Forum)
  Some time ago, I put the spare wheel on the rear offside of the car and the original went into the boot as the spare. Little did I know that the sensor is read by the ECU whether the wheel is fitted to the car, or left in the boot. There is no sensor in the original spare, so the car's ECU was taking the read out from the new spare, which had become low on pressure (down to 24 psi).
