• Volvo V50. 05 plate - Anti skid message brake failure, immobilser activa 30 Oct 2015 (Forum)
  thinks the work to vehicle and problems i am now experiencing are connected or just a co-incidence.I know from reading some websites this kind of problem is often attributed to CEM. Would like to explore all other possibilities first as I only had new ecu 5 months ago!!! Should say when I was at garage
• Ford Mondeo MK III TDCI 130 (6) Saloon - Alternator/ Battery charging problem 23 Jul 2015 (Forum)
  check this out and also suggested further checks on the wiring system. What I would like to know is what the likely cause of the battery light being on is, would fuse 99 have knocked something else out? Is a non-genuine Ford alternator a problem with the ECU and charging? Is wiring the likely problem
• Mk3 vw golf - Can anyone help me with my mk3 vw golf automatic?? 1 Feb 2015 (Forum)
  the gear box what gear it's in. £50 later and a new switch still not working. The only thing we can think of now is the ECU needs replacing. Is there anything we are missing before we fork out for one of those too? We can't find any wiring diagrams for a mk3 auto and the Haynes manual is useless! Can
• Independents vs main dealers, round 48 4 Jan 2013 (Forum)
  manufacturers to follow suit. “We just want a level playing field,” he said." End of article. The independent's comment about 'fallacy' of latest software is interesting. I've often wondered about this, having agreed to an ecu firmware upgrade on a past car, a BMW 120d, with a charge attached. If the software
• Citroen C5 (2001 - 2008) - 01 2.2 HDi EGR Valve and Swirl Chamber Diaphragm 22 Aug 2012 (Forum)
  the ECU faults read by a friend who does my MOT's and the only faults recorded were; 1, Glow Plug Fault 2, Mass Air Flow Sensor Fault 3, Swirl Chamber Fault The Glow plug fault does not as yet trouble me as the car starts fine even on a cold start and also as they seem to be a bit of a sod to get
• Pug 306 to 307 - Car upgrade, have I made a mistake? 11 Dec 2011 (Forum)
  for the ECU itself or something equally fatal also rotted. So I have now bought a 52 plate 307 2.0 HDI only to see many references to these ALSO having crappy wire used in the loom. So now I am wondering if as much as I like the car if the experienced professionals on here with experience of peugeots
• Fiat Punto ELX - Punto steering problem fixed! 23 Sep 2010 (Forum)
  connections, cleaned out the steering ECU, no improvement. Picked up on a couple of posts on different forums where people had solved the problem by re-soldering some of the joints on a circuit board inside the steering motor, so eventually took the plunge and had a look. Removed motor (marked
• 1999 R reg Chrysler Grand Voyager 3.3 LE LPG - Chrysler Grand Voyager 3.3 LE LPG help wanted... 10 Jun 2010 (Forum)
  overall diagnosis was that it must be the ECU that is failing because strangely the engine management light was not identifying the problems with the engine. The Chrysler garage want £95 to run the same tests that the RAC man did, and they have already started indicating quotes of over
• Vauxhaull Corsa CDTI - Black smoke 1 Jun 2010 (Forum)
  pressure coming from anywhere so that kind of rules out the head gasket. Could of course be the ECU but when its pluged in to tech 2 it works fine so not sure about that. I know the head gasket was replaced not long ago so could some thing be put back wrong like the gasket be on upside down
• Toyota Avensis (2003 - 2008) - Post-service - poor starting and fuel economy 6 Feb 2010 (Forum)
  Took my '56 2.2 (150) D4-D Avensis for its 40k service on Saturday. When I dropped the keys off at the service desk they explained that they also had to do an ECU re-program, as recommended by the factory. I'm not delighted with the results..... Symptom 1 - On the five or six occasions I have
• Ford Mondeo III (2000 - 2007) - TDDi 2002 - Fuel Pump problem ? 7 Nov 2007 (Forum)
  this money, it would absolutely 100% cure the problem :-) In addition, they have also gone a bit 'fuzzy' over my questioning around whether they have actually read the ECU on the Fuel Pump itself, which I am told is very important! The other information I want to share with the forum, is that they claim

• Audi high idling and cutting problem. 1 Apr 2006 (Forum)
  they started saying I also need a new ECU. One other thing I noticed is that when the air conditioning is on the car seems to only warm up to 75-80 degrees Celsius ( on the dash gauge). It used to always go to 90 degrees Celsius after a short drive. Another garage said it was the Lambda sensor.... Please
• Tyre speed rating surprise 28 Jun 2005 (Forum)
  in the first place. Even if ECU software is considered to be 'global' and in some markets lower rated (perhaps winter) tyres will be fitted, it's still a might odd maximum speed to choose for a limiter.
• Leon STDi - Temp Sensor & Economy 1 Mar 2005 (Forum)
  positon on the scale as it should when the engine is at normal temperature. I have a few questions... 1. is the sensor likely to be knackered providing an inaccurate reading back to the ECU. 2. I have had this car for four years since new and covered almost 100K miles in it. It has always taken longer
• VW Golf 1.8 timing question 21 Feb 2004 (Forum)
  distributor which is confusing my ECU even more? The guy who does my servicing is very honest and reasonable, and has always made a very good job of my cars before. But like everyone, he is human and humans do make mistakes. If I went back to him with some feedback that what he'd done was wrong, he'd

• Lights, Complex????? 11 Mar 2002 (Forum)
  was "are you sure there are bulbs in". I then phoned the Dealer in the Lake District that I bought my car from who informed me that they also had the same trouble and found that the ECU had to be told to activate the wiring even though there is no mention anywhere in Land Rovers information. They would do
