  I have removed the 918T ECU unit from my Rav 4.First I could not run the starter motor until I was told to connect together the leads going to Pins 14 & 15 on the 15 pin socket. Others may be interested in this as it took me a while to find this out. I was highly chuffed to find the starter motor

• Citroen C5 (2001 - 2008) - 03 2.0 Coolant sensor question 28 Nov 2008 (Forum)
  is this, why is this fault showing if the temperature gauge on the dash seemingly works OK, are there different sensors for the gauge and the ECU? The only sensor I'm aware of is the one on the side of the head below the intake butterfly. I'd take it in to be looked at but money's tight at the moment. Thanks

• Peugeot 206 hatchback (1998 - 2006) - 02 1.1 Power loss - air leak 17 Nov 2008 (Forum)
  Wondered if you clever people could help. I have a 206 1.1L, which keeps cutting. Have had the lambda sensor changed, ignition coil changed. The ECU keeps coming up with ignition coil problems, but new one isn't faulty. The garage said it was a small air leak, too small to find therefore, too
• Volvo S40/V40 (1996 - 2004) - 98 2.0 T Climate Control Fault 15 Oct 2008 (Forum)
  the climate control ECU is and if there are any common problems associated with the climate control system on these models? The Haynes manual doesn't cover this in much detail. The car isn't worth much so I'm trying to avoid having the DTCs read. Thanks in advance.

I took it to my local garage and they reckoned it was sumthing to do with the ECU, so they just said to take it to Vauxhall. Does anybody know what the problem might be? Thanx

• Mercedes Benz E-Class W210 (1995 - 2002) - '00 E430 Automatic Gearbox Won't Respond 21 Mar 2008 (Forum)
  automatically or by overriding with the tiptronic function. In either case, pulling over, switching off and restarting the engine cures the problem for a while. My instinct is ECU - especially since restarting fixes it. Any suggestions? Thanks drawde
• Audi A8 (1994 - 2003) - 01 2.8ltr petrol (APR) will not start 15 Mar 2008 (Forum)
  started easily. Is there an ECU upgrade or fix or maybe something like a dodgy sensor that I should replace. The car is a dream to drive, but if I can't rely upon it, then its going to have to go! Any help, thoughts, ideas or indeed experiences would be great Engine details edited in

  Hi, I have recently fitted a 1.4 zetec SE engine (2001) into a mk4 ford fiesta 1.25 (1998). Upon attempting to start the engine the engine is cranking but wont fire. It appears to want to fire but there is something stopping it. I have had a diagnosis on the ECU where a problem
• BMW 1 Series E81/E87 (2004 - ) - Automotive Diagnostic Tools 23 Jan 2008 (Forum)
  Virtually all modern cars require these infernal ECUs' to be interogated using a diagnostic tool when the MIL illuminates on the dashboard. My questions are: what is the difference, if any, between a 'code reader' and a 'diagnostic tool'? I have read that in 2001, due to legislation in the USA
• FIAT Panda 4x4 (2005 - ) - 1.2 petrol, Rough running in freezing weather 14 Dec 2007 (Forum)
  explanation there is that it's due to a mapping fault on the ECU,a design fault and not remediable. Has anyone else experience of this on what is, after all, a very common engine in the Fiat range? I don't really need a cure, just interested in the cause, that's all.

• Peugeot 307 (2001 - 2007) - HDi 110 - power loss at motorway speeds 19 Sep 2007 (Forum)
  this happens but there is no real power and the car loses speed. Has anyone else experienced this? Is a diagnosis of the ECU error messages likely to help? There seems to be some read across to other people's experience with the engine giong to limp mode. Any thoughts or advice will be very welcome.

  of a button remapped by Griffin's British Touring Car team. Knowing that these engines are the Alfa/Fiat 1.9td 16v 150 BHP, and also used by Saab, but all have different ECU's.
