• Chrysler Voyager (1997 - 2001) - 2000 2.5 immobiliser problems 23 Sep 2009 (Forum)
  today and ecu had stored code of fault on transponder but they say transponder checked out ok and can not do anything untill code is active- got new key and fob on order as they suggested this may be the problem as we only have one set and key is worn(so need a spare anyway £200) they also say
• Ford Mondeo III (2000 - 2007) - 05 2.0 a/c fan not working 26 Jun 2009 (Forum)
  is parts people say they don't have a fan switch, Mk3 ECU does all that??? I've had it regassed, and its ice cold on the go, so it's not that. I've changed the low pressure switch, not that. On advice that it's been a cause of identical problems, I've tried a new 60amp fuse, but it made no difference. I
• Volkswagen Golf IV (1998 - 2004) - 2000 1.6 EPC / Exhaust System Light - At wits end 11 Sep 2008 (Forum)
  independent, but a couple of months ago the lights came on as I was passing the authorised dealer - so I took it in there and the ecu fault indicated the throttle position sensor to blame. An air intake hose was replaced and the accelerator pedal fault was noted as "sporadic and may return". The sensor light
• Ford Focus (1998 - 2004) - 2000 1.8 Temp gauge into red, fan running constant 18 Aug 2008 (Forum)
  couple of days it has been on constantly for the hour long, 10 mile commute across town. Then as I mentioned the temp gauge went to red. My knowledge of car engines (especially for anything controlled by ecu's) is very limited but I'm willing to learn. Any suggestions on checks I can undertake
• Ford Focus II (2004 - 2007) - 2004 1.6 - engine weak! 7 May 2008 (Forum)
  the rest? No misfiring (ie ignition) problems. Could the ECU anti-knock feature come into play and cause the ignition to retard when it shouldn't? I have been trying to record this sound to make it plain.
• Mercedes Benz E-Class W124 (1985 - 2000) - 1994 E320 Coupe - Cruise Control problem 2 Apr 2008 (Forum)
  forums which basically seem to go in the direction of swapping out various expensive ECUs to see if the problem goes away. I'm guessing if I take the car to a MB dealer they will probably adopt the same strategy. {yes, you guessed it, another edit to put the year in the subject line. That reminds me
• Rover 200 and 400 (1989 - 1996) - 216 (honda) won't start 12 Sep 2007 (Forum)
  it I can feel no click. Ruling out the inertia switch - would stalling the car have any effect on any ignition components like the igniter unit or the ecu. When I turn on the ignition I can also hear a hissing sound that comes from the region of the fuel injection components. This lasts for a bout
• The Right to Repair Campaign 31 Jul 2007 (Forum)
  systems to effectively 'veto' any repairs until the replacement part is coded (or 'commissioned') back onto the car. Some BR's will be aware that this already happens when some ECU's, dashpanels, MAF's etc are replaced, but with about 50% of cars now using CANBUS it could soon be that even very minor
• Ford Mondeo 1995 idle speed control 28 Mar 2007 (Forum)
  ? It seems to run ok, but I would assume that thew ECU will eventually "learn" this and alter the way the car generates power? Any thoughts would be very much appreciated! Ta!
• 51 Mondeo Misfire 19 Jan 2007 (Forum)
  and everything seems fine. I've replaced HT leads. Oil and plugs were changed by a main dealer 3-4 months ago. There are no warning lights and a local garage checked the ECU and found no faults. I'm not keen on taking it in to the local Ford garage without some idea of where the problem could lie. I'm also
• Rover 214 Engine Stalling ? 24 Dec 2006 (Forum)
  removed the petrol cap. I am wondering whether there could be a blocked vent somewhere which is causing a partial vacuum to develop. If so, wheer would this be ?? I have rigged up an LED in line with the 12V supply to the pump so that I can eliminate any possible electrical fault in the ECU pump Relay
• Exploding Corsa 1.0 Life (2003) 21 Apr 2006 (Forum)
  would need to pay for it to be delivered to dealership but they won't consider this until they have seen a copy of the report! Is anyone aware of similar problems with this car? I was told by manufacturers that all Corsas from this year need replacecment ECU's which the dealerships provide free under
• Italian Electrics 26 Oct 2004 (Forum)
  the ECU and cause real problems. I know Italian electrics have had a reputation for being a bit eccentric in the past, but I thought they had got their act together by now. Or is he just unlucky. (With apologies to the Alfa fans on this forum)
• Vx Omega - how do u switch auto box on? 7 Aug 2004 (Forum)
  has a new £7k piece of kit which plugs into the ecu giving fault descriptions as well as codes. As far as I can tell the auto box seems to be operating ok, altho it did clunk a little when not used for a week to start with between changes. I'd be grateful if anyone could shed any light on or ideas
• Toyota Yaris - Keys and Deal questions 15 Jun 2004 (Forum)
  , and has not opened the bonnet since he got it a year ago. Thirdly, he hasn't got the master key, only one (slightly bent) normal key, and after a bit of research i've found out that getting a new master key could cost up to £1000 due to the ECU having to be changed in order to have a new master key! My
• Xantia Misfiring 3 Oct 2003 (Forum)
  them. Today, I formally threw in the towel after checking the following, Exhaust seal - good. ECU light - off. Fans - work but not via sensor located on Thermostat housing along with a couple of others - changed sensor - no avail. poor cylinder - none were obvious, disconnected each injector
• Engine vibration, Help. 7 May 2003 (Forum)
  (with the exception of the spark plug for the number 2 cylinder, it is a bit carbonised) - Check all the hoses & ducts for leaking electrical connections, & everything seem OK - Self-diagnosis for the ECU (modes III, IV & V) & there is no error message - If I increase the engine to 3,000 rpm, there is some abnormal

• Tact or dynamite? 5 Jan 2003 (Forum)
  the warranty company who actually carried out the substandard work and risk losing 'good will' for the rest of the 6 months remaining on the warranty ( I have already claimed for a new ecu and power steering pump as they both failed not long after I had the car so that was about £600 worth)? There is a shadow

  , under a "misfire detection code." Then engine speed will be limited until you replace the plug and have the ECU reset at your friendly local Vauxhall dealer workshop. A Vauxhall spokesman says, rather aoplogetically, that his compnany is by no means alone in this and that it is "all to do
