• Ford Fiesta - Ford Fiesta (Endura-E) over-revving on startup 25 Nov 2013 (Forum)
    I've put in a new air filter, new IAVC, used electrical cleaner on all the sensors' plugs and sockets, new breather cap and reset the ECU... All to no avail. Bearing in mind that the car had new oil less than six months ago, has only done 20k miles and is generally treated like a king, what could be up with it? Is there anything I've missed?
• Peugeot 406 hdi - MAF sensor faulty 20 Jul 2013 (Forum)
    I have a 406 HDI 2000 model (90hp) which has lost all power up until a week ago the car was going find and then all of a sudden one day its just lost everything its so flat you could almost walk faster. i have checked all the obvious things replaced fuel filters etc.  I did have the ecu codes read and it was showing MAF sensor short so we cleared the code but still no power.  There is no checklight on the dash.  i decided to clean the maf sensor but again still no change.
• Volkswagen Golf V - Misfire only on subsequent journies 11 May 2013 (Forum)
  Diagnostic check throws up fault code N242 on Cylinder No3 'P1267 Regulation Range Exceeded-Intermittent' yet it can't be a mechanical fault as the car will drive perfect all day as long as ignition is left on. Is there a sensor which feeds to the ECU only on ignition? The cylinder No:3 and its wiring loom was replaced by VW only a year ago (£850) after their own Diagnostic check  threw up the exact same fault code. I am beginning to think that the cylinder and wiring loom was fine and that the fault is elsewhere but manifesting itself on Diagnostics as cylinder 3!.

• Mazda3 - MAZDA diesels DPF problems still 31 Jan 2012 (Forum)
     Now Mazda Australia will not warranty the unit as; the the ECU cycle was NOT reset at each oil change (10K).  I have a valid reason for this, its because I did the oil changes myself, Mazda serviced the car at 40K, 60K 80K and 120K, the DPF blew after the 120K service (that service cost me $1300.00AU)   at no point was I ever advised that this needed to be done or warranty would be denied, I even bought the oil and filters from the dealer where I bought the car.

• Citroen saxo 1.4i auto - Sluggish acceleration problems 8 Feb 2011 (Forum)
  I'm lead to believe in thinking it could possibly be the Throttle potentiometer, as these can wear out??? Any thoughts from anyone would be a help...O and also I have had the ecu checked out and plugged into a gizmo, but no fault codes were shown.

• Citroen Xsara Picasso 2002 - warranty 18 Jun 2010 (Forum)
  It is not part of the power steering unit. The power steering unit consists of the pump, reservoir and ECU. The ram is part of the steering rack but has no input into the vehicles steering. It is a safety device to stop kickback during small accidents such as hitting kerbs. This is why it is not listed under the "Steering" section of coverage."
• What car next? 6 Jun 2010 (Forum)
    It has just this week broken down (again) with no warning and left me stranded on the A14. The fault this time is electrical necessitating a repair 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?)
• 1.9 TDI 115PS - Ford Galaxy Turbo Problem 20 Mar 2010 (Forum)
  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 in the manifold just prior to where the manifold joins the cylinder head and underneath the front vacuum unit which is part of it, there are signs where oil/oil vapour has been leaking which would explain the smell of burning oil in the cab.
• Volkswagen Passat (2001 - 2005) - Use independents? Yeah, right! 7 Feb 2010 (Forum)
  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 this bloke assures me that it's not the brake switch.
• 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 on and it didn't fix it - so he put the old one back on. So last Monday i took the car to local Ford main dealer.
• Volkswagen Golf III (1992 - 1997) - 95 2.0 GTi electrical fault 4 Nov 2009 (Forum)
  hi there, i'm new to the site, i have a 1995 mk3 golf gti 2.0 8v engine code agg i recently parked up the car over night and returned the next morning to find it would not start although it was cranking, got plenty fuel getting to engine but found no spark, changed the obvious coil but to no joy so changed crank sensor, dizzy cap and rotor arm, still no joy, all relays are correct and present. after some head scratching and testing i found that the 3 pin connector that goes to the distributor was at fault as all 3 wires had a 12v feed, the brown/blue wire is earthed when ignition is off but becomes 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, if this if at fault would it cause this short? any help on this matter would be greatley appreciated, if i put a permanent earth to this wire it runs sweet as a nut but i know this isn't correct and has to be rectified, regards jakey
• Vauxhall Corsa B (1993 - 2000) - 99 1.2 Car keeps going into limp mode - causes? 26 Jun 2009 (Forum)
  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 code low lambda voltage. He was not sure how this could cause my power loss so he looked deeper into the history and found my engine keeps going into limp mode. EGR valve is apparantly fine or at least no errors codeded there.

• Renault Clio II (2001 - 2007) - 01 1.2 cutting out at junctions etc 18 Sep 2008 (Forum)
  Heard so much about this problem for a long time, read all the forums, nothing definate to fix problem, throttle bodys being replaced putting the fault 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 for a good while the suddenly at the next junction, stalls, light flashes on, revs up nad down.

• Vauxhall Vectra C (2002 - 2008) - 06 1.9CDTi automatic gearbox - jerky changes. 13 Feb 2008 (Forum)
  On one occasion I used manual override to change from 6th to 5th and I was left with no drive to the wheels, the engine on maximum revs (it was in cruise control) and doing 70mph in the outside lane. The cas has spent 4 weeks with the Vauxhall dealer in which 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.
