• Ford Mondeo - Mondeo Glow Plug Warning Light 1 Jun 2012 (Forum)
  I've seen on the site about other people having the same problem as I now have, Glow plug warning light coming on, and was wondering is anyone has replaced the diesel injectors on their car.

• Vauxhall Astra G Petrol - Engine Warning Light - Is it an MOT fail 2 Apr 2012 (Forum)
  Hi, A warning light is permanently on on my dashboard.  It's in yellow and it's a little picture of a car with a spanner.  It is on due to an ECU fault and all the car's systems work fine. Will my car fail it's MOT on this now or in the near future due to the MOT rule changes, assuming everything else is OK?  Incidentally, It passed it'd last MOT with it on.
• Renault Modus 1.5dci - Power Steering Problem 12 Mar 2012 (Forum)
  Got a "steering fault" message on the Modus today. Power steering no longer operational. Scanner code comes up with "106" which is an ECU fault apparantly. I've checked all fuses and they are fine. I've also disconnected the battery to see if that resets anything overnight. Any thoughts on what else it could be or how much to fix if I need a new steering column (with electric power steering motor)?
• Jaguar XJ8 Sport 1997 R Reg - Stability Control Amber Warning Light 9 Jan 2012 (Forum)
  In the past switching off & on the ignition has cleared the problem but not this time. Does this suggest an ECU or ABS module fault and will it be an expensive repair given the age of the car? Does this come within the current MOT scope or will it when changes happen in April? Regards G.S.

• Volkswagen Golf V - How to spot ESP issue 18 Aug 2010 (Forum)
  Assuming there's nothing in the service about any issue being addressed, is it just a case of a warning light on the dash? HJ talks about dodgy sellers unplugging the ECU (so the warning light does not show?); where is this on a Mk5 Golf, and is it just a case of checking its plugged in?

• Volvo C70 (2000 - 2005 ) - 00 2.0 can the day running lights be turned off? 6 Oct 2009 (Forum)
  is it possible to turn off the dip beam lights that automatically turn on when the car starts.I beleive that volvo dealers can do it by resetting part of the cars ecu,however they are likely to charge £40 plus . Is their a DIY option.The function seems to irritate other drivers who often flash thier headlights.Tony
• Ford Mondeo III (2000 - 2007) - 03 2.0 Camshaft sensor 2 Jan 2009 (Forum)
  I am a fairly experienced amateur, but most of my experience on older cars with more machanics than electronics. Does the sensor need any special kit, or does it need programming into the ECU etc Cheers Petrol or Diesel ?

• Omega misfire 30 Mar 2006 (Forum)
  Some of you will remember that I had the crankshaft sensor repalced last spring as it was cutting out when hot. This seems to be another heat related problem. Is the ECU likely to have a fault code (I have details somewhere on the paperclip trick) or am I into a "trial and error" sequence with the garage?
• Passat - rough idle 9 Feb 2006 (Forum)
  (I suspect this is immediately after replacing battery and he hasn't actually driven far) Any ideas - he had some idea of ECU's 'losing' settings and having to re-learn them, but surely the idle setting is the idle setting ? Go on, get out of the car... http://www.mikes-walks.co.uk
• Bluefin 3 Nov 2005 (Forum)
  Hi, I have put a deposit down on an ST200 Mondeo. ( I couldn't find an ST220 within my price range ) The car has Bluefin. I've been told that this Bulefin reprogrammes the ECU to increase BHP by about 5%, quite how I dont know. Does anyone have any experience of Bluefin. The fuel economy of the 2.5 Duratech isn't the worlds best, with Bluefin fitted are we talking gallons to the mile?
