• What car next? 6 Jun 2010 (Forum)
  to the ECU - earth pin on number one cylinder injector. Much as I love the old barge, I don't have faith that this car won't fail me again. It has a small oil leak coming from somewhere behind the engine block (gear linkage?)  and drips occasionally on the garage floor so I am thinking
• 1.9 TDI 115PS - Ford Galaxy Turbo Problem 20 Mar 2010 (Forum)
  pressure which smoothes out at higher revs. Have just had the codes read which give a code of P1557 (turbo pressure control) and P1570 ( engine ECU blocked). I am suspecting the N75 pressure control valve but having taken the the engine cover off this a.m., there is this'unit' bolted
• Volkswagen Passat (2001 - 2005) - Use independents? Yeah, right! 7 Feb 2010 (Forum)
  to know the exact cause. Went down to the local VAG "specialist" (according to their website) who quoted £60 + VAT just to pull the ABS fault code from the ECU - more than a VW dealer! When I asked if it might just be the switch, I was asked if the coil light came on at the same time. It didn't, so
• Ford - How to approach Dealer after repair that wasnt fix 29 Jan 2010 (Forum)
  Evening, My car (2001 Ford Focus 1.6 Zetec) has a very annoying problem where it is "stumbling" at idle. I had a local mobile mechanic come and have a look and plug in his computer - but the ECU was registering no codes. He thought it might be the Idle Control Valve so put a new one
• Volkswagen Golf III (1992 - 1997) - 95 2.0 GTi electrical fault 4 Nov 2009 (Forum)
  12v when ignition on, this appears to incorrect, i put earth using power probe when cranking and it started, but i'm stumped as to where the feed comes from so i can find the fault, is it an internal fault with engine ecu? only faults present using ethos scanner is throttle position sensor fault
• Vauxhall Corsa B (1993 - 2000) - 99 1.2 Car keeps going into limp mode - causes? 26 Jun 2009 (Forum)
  The error code is lambda sensor low voltage. Basicaly I have made a post a few weeks ago about my car loosing power but no error code was recorded. Today it lost power again this time more scary than the other ones. I took it to my mechanic who had it on his expensive ECU tester and found an error
• Toyota Avensis (2009 - ) - 2009 model - details released 24 Oct 2008 (Forum)
  as an option in the UK - All petrol engines have been updated 1.6 - 132 HP - 160nm 1.8 - 147 HP - 180nm 2.0 - 152 HP - 196nm Some rumours say that the petrols can be ordered with 6 speed autos too. We'll see.... Diesels apparently stay the same but have updated ECU maps for better economy. Toyota have
• Renault Clio II (2001 - 2007) - 01 1.2 cutting out at junctions etc 18 Sep 2008 (Forum)
  right and also not putting the fault right. This partiucular clio has had a map sensor, lamda sensor, wiring to ecu repaired, coil pack, brake switch totalling £600. I got it today, and after some time spent on it, i am convinced its the throttle body. the fault is intermittant, can run perfect
• Toyota Previa (2000 - 2007) - 2002 2.4 Engine Malfunction Light 15 Feb 2008 (Forum)
  / Picnic. DESCRIPTION OF PHENOMENON ? Engine MIL ON. ? Code P0420 or P0430 in the engine ECU. ? No influence on driveability or engine performance. The above Toyota Service Bulletin was issued in May 2005, as you can see it not only affects the Previa but a lot of other models as well. The fact Toyota
• Vauxhall Vectra C (2002 - 2008) - 06 1.9CDTi automatic gearbox - jerky changes. 13 Feb 2008 (Forum)
  time it has a new gearbox, a new ECU and then another new gearboxes fitted before the dealer believed that the problem had been fixed. All of this work was done under warranty with guidance from Vauxhall technical support and included about 180 miles of testing. Having got the car back I am
• Vauxhall Cavalier (1988 - 1995) - '89-'941.6 (c16nz) fuel mixture problem! 29 Dec 2007 (Forum)
  on the uptake (after the injection gas jet). the same problem I cleaned the injection. The same problem I changed the ecu and i still have the same problem! The motor light is still flashing (like a bad electric contact) what else i must check?? Thank you Hi I guess you're posting from abroad ! Hope you
• Vauxhall 14XE engine - a lemon? 10 Mar 2006 (Forum)
  told that there is an ECU upgrade for this engine; anyone know anything about this? Thanx in advance.
• Peugeot 406 stalling during warmup 20 Jun 2005 (Forum)
  thought that the ECU is perhaps getting incorrect temperature information from the coolant temperature sensor, but when I trakced it down, there is a nice new shiny sensor already screwed into the housing, so someone has tried to fix this before (yep, we?ve just bought this car?.) I might be in luck
• Renault's insane design 12 May 2005 (Forum)
  wire running from the crank sensor to the ECU. The wires are really thin and the plastic had gone hard and fractured - this on a car only four years old! Anyway I test drove the car and noticed that it was missing slightly and the gearbox was crunching a bit due to 'clutch drag'. I have discovered
• Focus TDCi injector fault / power loss 29 Apr 2005 (Forum)
  particularly prone to damage)which feed back data to the ECU, which shuts down the fuel delivery, presumably to prevent further damage. it's not a critical fault, so the glow plug light does not flash. I am told that the best you can expect to pay for an injector is around £300 from an independent, but you
• Peugeot non start 3 Aug 2004 (Forum)
  start! The relay clicks when iginition is turned on but cant hear the pump turning on. Is it the relay which could be faulty cos of my water antics? or is something more severe like the ECU (have checked it and only a small water mark on it which is dry now, shoke it to check theres no water inside
• Vectra 2.0 DTI acceleration stutter 17 Apr 2004 (Forum)
  . However when I unplugged the AFM my ECU light came on and I couldn't rev the car over 4000 RPMs. So I'm doubtful that could be the problem. The problem is that when you accelerate between 2500 - 3500 revs the car seems to loose all power for about 1-2 seconds. It then picks up and continues
• 306 XSi Engine behaving oddly... 11 Jan 2003 (Forum)
  comes on for a few seconds goes off. Throttle can become jerky, like an on/off switch. When it's in this mood and I put it in neutral and take my foot off the throttle normally the engine sinks below idle and dies. Sometimes the ECU revs the car repeatedly and the revs bounce and sometimes it recovers

  to taking out a fuse eg, but do I run into further problems with petrol contamination of catalyst? or loss of ECU settings which can be even less desirable? The plug leads are not immediately accessible in the dark! PS For info - Alarm on same car. Having had intermittent alarm problems I finally
