  This car has the AN 55/50 gearbox Having got the fault code.... P0748 Pressure Control Solenoid "A" . This code indicates an electrical fault meaning the fault may be TCM (already swapped out), ECU (already swapped out) Solenoid itself (swapped out
• Ford Fiesta 1.25 - Servicing 18 Aug 2010 (Forum)
  that they will update the ECU software - is this a reason to stick to the main dealer? I should add that I normally do all my own basic servicing (oil, filter , brake pad changes etc) but normally with cars out of warranty and we usually reckon to keep cars for a fair number of years.    
• Jaguar XJ Super 8 Auto 4.2 2003 72k miles. - Gearbox malfunction ? 3 Jul 2010 (Forum)
  body with a bill north of £4k. A mechanic friend suggests the gearbox may be getting misinformation from the ECU (???) since the problem only occurs when crawling in traffic queues or similar situations. Needless to say my confidence in the dealers solution is undermined by their indecision
• SpeedSpike Camera`s - you know it makes sense. 21 Apr 2010 (Forum)
  feeling it`s an opportunity missed though. Surely the technology exists to govern cars speed direct from the ECU - via global positioning and also regulate the gap to the car in front? Somehow, you just know that`s the future and an election winning policy for the first political party to embrace it.  
• Peugeot Partner Combi (2001 - 2004) - 03 2.0HDi starting problems 22 Feb 2010 (Forum)
  system helped to start the engine. The dealer has also re-checked the valve timing. After a lot of testing the dealer believes the fault lies with the ECU (a Siemens model). It is giving strange readings (when the engine is not running) and it appears that it is not allowing the sensor on the camshaft
• Vauxhall Vectra B (1995 - 1999) - 99 2.5 Car running like stink 24 Jan 2010 (Forum)
  I picked it up it ran really well. After leaving it over the Xmas period, it runs like stink and its missing on cylinders 1 and 4, all leads and plugs have been changed and the coil pack has also been replaced to no avail, I've now been told by the garage that I use, that its possibly the ECU
• Audi A8 (1994 - 2003) - 97 4.2 S8 refuses to start 7 Nov 2009 (Forum)
  on it so it stopped on LPG last night. I have tried to VAGCom it but I cannot establish communication with the ECU (not good). I thought it may be the fuel relay but that it is not where it is supposed to be according to the manual which is in the fuse compartment in the RH footwell, there are no relays
• Citroen Berlingo Multispace (1998 - 2010) - 09 1.9 1.9 diesel - engine cuts out intermittently 12 Sep 2009 (Forum)
  filter housing and replaced the fuel filter - I don't think fuel supply to the pump is a problem. I've taken it in for a diagnostic check at the local Citroen dealer and no fault was apparent. The mechanic suggested that the problem could be a solenoid on the diesel pump that communicates with the ECU

  the system works ie. from ecu to relsay to sensor , pump etc etc
• Citroen Nemo Multispace (2009 - ) - Cruise control 30 May 2009 (Forum)
  system was that various things could be added and the ECU programmed to work the new addition. If I cannot have an OEM unit I will have to go with an aftermarket CC. Does anyone know of a reliable aftermarket unit? The engine is the 1.4 Hdi. Thanks for any help you can offer.

  relay, the brown one near inner wing. Had all codes checked - there are no codes in ecu. The only thing i haven't changed is the pump in tank. Could this be the problem? Oh and checked for air leaks just in case, none there either. please can someone shed a light its doing my head in, thanks
• Mazda Mazda 6 (2002 - 2007) - 03 2l td oil pressure light on 28 Mar 2009 (Forum)
  or anything the engine seized.Got a recon engine but when engine was put in and started everything seemed ok but over 1000rpm the low oil pressure light comes on,pressure switch was changed and no leaks but still the same.Garage say it could be the oil pump ? Could the ECU need reset after the engine seizing

  Hi can anyone help me I have a E46 2ltr which has started intermittently cutting out & will not start for about 30 min. When it cuts out all warning lights light up. it went on diagnostic & came up with numerous errors including camshaft timing - too late, engine speed sensor - no signal, ECU
• 12 volts really 14 volts? - Just a query. 17 Feb 2009 (Forum)
  all the electrics are rated at 12v, so howcome the altnerators always tend to read more? I thought the output was supposed to be heavily regulated unlike the old dynamos. I am right in thinking things like the ECU have further regulation to ensure it has exactly the correct voltage? I know on a PC
• Volkswagen Golf V (2004 - 2008) - Retro-fitting Cruise Control/PDC 3 Feb 2009 (Forum)
  that claim to be VW parts, which look to be effectively a new indicator stalk, with the associated buttons/switches on. I had a 1991 BMW 730i for a short period, and the previous owner had fitted Cruise himself, and told me it was as easy as installing the new stalk, and plugging it into the ECU under
• Vauxhall Vectra B facelift (1999 - 2002) - 00 1.8i Fault code p0352 - Ignition coil 2 and 3 11 Dec 2008 (Forum)
  !! Anyway, I have used the paperclip method and have retreived the following code from my ECU :- 0352. Via google, I have found that this is listed as 'Ignition coil 2 and 3' What does this mean ? What do I need to do to resolve ? Cheap options are preferred, we have just had a second child and cash
• Citroen Saxo (1997 - 2003) - 99 1.6 Engine suddenly dies while travelling along 9 Dec 2008 (Forum)
  suggesting it was fuel linked. My garage have checked every circuit etc. using their diagnostic computer and failed to find a fault. The ECU has been checked and found OX. All manner of suggestions have been proposed but their attitude seem to be ' lets replace this' (ie throttle housing' or crankcase sender
• Peugeot 306 (1993 - 2001) - 01 2.0 HDi starting problem 24 Nov 2008 (Forum)
  plug light to come on it still doesnt start straight away. It will turn over but not fire up. Theres only a couple of occasions where it starts and stops straight away. Im just hoping theres a simple obvious fix rather that the immobiliser or ecu etc. Are there any obvious faults on these cars
