  of smoke,it then clears itself & the van runs perfectly at higher speeds.Im led to believe the ecu & other various sensors controls the advance/retard fuel timing on the injection pump regarding this engine.Could it be a dodgy multiplug connection somewhere or has the pump solenoid shot its bolt?.One other

  have had RAC out 4 times!). Can be better after a cool down and it is always OK next day at the garage - has been back each time but not fixed.

  no difference at all. I'm at the point where i want rid of the car but i can't sell it like this! I have read a few things online where its been suggested it could be the ECU, also could be a MAP sensor?? Any help is greatly appreciated!
• Volkswagen Beetle (1998 - ) - do I need to disconnect battery whilst charging ? 30 Jan 2009 (Forum)
  whilst charging, to avoid possible alternator damage. What are the Backroomers thoughts on the need for this? Can't say I've ever disconnected the battery from the car before? Presumably this would result in the ECU resetting itself, needing to dig out the code for the radio etc. Is it really
• Volkswagen Lupo (1999 - 2004) - 03 1.4 Misfiring when cold 4 Dec 2008 (Forum)
  of the heater element in the lamda sensor, causing the ECU to think the engine is running too rich when it is cold, so it makes the mixture leaner until the mixture till the engine misfires. Once the exhaust gas has heated up the lambda sensor, the problem goes away. What do you think? If I could find out

  and I take it out of gear, re engage the gear and then lift the clutch pedal the revs increase with the accelerator and everything is as normal. Also when in heavy traffic and the vehicle is at idle for a prolonged period of time the revs will icrease to approx 1300 RPM and the ECU light will come
• Mazda 323 (1998 - 2003) - 2002 2.0 Correct way to use jump start leads? 16 Sep 2008 (Forum)
  ' in the discharged car's engine bay. My FiL followed this method to jump start his petrol Corsa C. As soon as he put the lead on the engine hanger of the Corsa it sparked. The car then started okay with the jump but it later transpired that the ECU was fried! It's possible that on trying to use a battery charger

• Reliable diesels - is there such a thing? 16 Mar 2008 (Forum)
  ECU and fuel injection problems, clogged valves...you name it.... From reading this forum, the 130bhp Mondeo seems dogged with similar problems, ditto the Mazda 6. I'm after a diesel. It needs to have a big boot for the dogs. It needs to start in the morning without worry. The Skoda sounds great
• Ford Fiesta (1995 - 1999) - 1998 1.3 - Engine trouble 22 Feb 2008 (Forum)
  1242cc 16v 1998/R reg Hi, My engine had seized up so I bought another one (exactly the same even down to the year of manufacture) and fitted it. Upon attempting to start the car it is cranking but not firing. This cant be an ECU problem because the engine is exactly the same as the old one even
• 306 hdi injectors or alternator pulley? 4 Mar 2007 (Forum)
  -would this accur if the pulley was worn My other question is if i come across some injectors (if that is the cause) i know about matching part numbers on the top of the injector but would the ecu have any problems recognising the new injectors if i get a complete set of the same number? sorry

• Allergic to Modern Cars 14 Sep 2006 (Forum)
  . However, I CAN drive old, basic diesels - MK1 mondeos are a firm favourite. However, as these are now hard to come by I'm wondering what the least complicated new-ish car might be - no ECU ETC. To be like this is very debilitating .... so, I thought it was worth a stab to pose the question on here
• Renault Scenic gone crazy!!! 5 Apr 2006 (Forum)
  no faults showing! I took my son to football this evening, as i got back into the car to go home, the following warnings came up, "ASR and ESP Failure" "Passenger Airbag deactivated" and "Parking Brake failure"!!!!! I suspect a faulty ECU, i know the car is under warranty, but was wondering what the problem

• 306 Dturbo diesel pump and immobiliser 26 Apr 2005 (Forum)
  thought id try here. Will I need to swap the pumps over? surely the code is stored in the ECU and that then sends a signal to the fuel shut off valve in the pump? The pump on the new engine is slightly different in that it has a damper and a pipe leading to the oil filler, whereas the old one doesnt have
• Alfa woes & Test of New GT 24 Jan 2005 (Forum)
  Wed. before Xmas the clutch started slipping on my Alfa 156 JTD. Its was due a 96,000 service and for the airbag light to be investigated. Actually picked it up yesterday, clutch problem turned out to be a leaking rear seal, ECU was the problem for the airbag light. Clutch takes 7.7 hours
• Servicing CD's -- are they useful? 18 Jun 2004 (Forum)
  Previous postings have told of car maintenance CD's offered via eBay and one poster, at least, was satisfied with what was obtained. My experience was not so good. The 'factory Service/Repair manual' turned out to be pretty useless. It showed me where to plug in an ECU analyser, if I had one
• Citroen Xsara Brake Lights 2 Jul 2003 (Forum)
  workshop with the ECU being replaced, prior to this it was 3 days with various switches being replaced. The fix usually lasts about 2 weeks then guess what ? Yep the 10 amp fuse goes again, the main dealer has suggested I uprate the fuse to 15 amp to stop it blowing! I'm a bit reluctant as the fuse
