• Vectra 2.0 DTI 16V Low Power 18 Mar 2014 (Forum)
  think the fuel pump is not delivering full fuel, is there any way to test these fly by wire pumps without selling my house and using a vauxhall dealer as it seems with these engines they have no idea what is wrong when the ecu light is not on.If anyone can shed some light on the problem please let me
• 2003 Ford Focus auto 1.6 - Disconnecting the battery 27 Dec 2013 (Forum)
  disconnect the battery the ECU will lose the information stored in it's memory (KAM), this includes idling and operating values  and any fault codes detected, it goes on.......... Also the Ford keycode audio unit will not function again on reconnection until the security code is entered (I bought

• Vauxhall Astra G Petrol 2002 1.4 LS 16V Z14XE - Misfire Cylinder 3 16 Jan 2013 (Forum)
  Hi. I have an 02 plate Astra 1.4 16V engine type Z14XE, which has misfired on Cylinder 3. This isn't the first time this has happened (about the 6th or 7th) I've had the plugs changed twice, new coil pack, new ecu, new egr, and a software update but the problem still seems
• Peugeot 206 - Intermittent starting problem 12 Jan 2013 (Forum)
  . The same problem occurred again, and the garage cannot seem to replicate the problem, telling us that "the car starts every time". We know that it does from cold, but not when warm. The second suggestion was that we have the ECU replaced, an option that we does not appeal owing to it's cost and the fact
• Ford Mondeo - DPF and oil warning 2.0 tdci 24 Sep 2011 (Forum)
  shed any light on this, as at the moment I am not sure whether to wait to get it serviced in a couple of months time, or whether it needs an immediate oil and filter change and an ecu update.
• Vauxhall Corsa D 1.3 CDTI 90PS 2007 - Erratic revving 4 Jun 2011 (Forum)
  but have ruled that one out.  Checked the oil levels this is ok, as I have heard that over filling can cause the problem with an over revving engine.    Problem occurs when air con is both on and off. Could it be a sticking throttle response or something else, there are no ECU

  light comes on and stays on. ive had the oil and filter changed.used a fuel additive to remove any carbon deposit on the valves and had the camshaft sensor changed.the ecu light stays off after resetting until the engine is cold .When i start it from cold the camshaft ? knocks

• Ford Mondeo mk3 2ltr zeetec 51 pate - Speedo drops to zero and starts to missfire 13 Feb 2011 (Forum)
   Hi anyone had a similar experience, it would appear to get worse when the electrical load on the car is increased. Have cleaned all the earth points and had the ecu cleared and rebooted with the latest software updates but still the problem exists. This firstly started when i changed
• Mazda 3 ts2 2.0d 2008 - Sump oil rising fast 14 Dec 2010 (Forum)
  to the ECU for the DPF warning setting. Mazda refused the warranty claim saying this is a serviceable issue. I  note from the injector readings that one injector is way different to the other 3.  I note that the sump oil has risen by over 10mm in the last 900 miles
• Hyundai i20 - Hyundai i 20 10 Nov 2010 (Forum)
  the warranty went, a month later the ECU decided to die, leaving me stranded and with a £ 600 bill. This had obviously narked me big time, and I vowed never to buy Hyundai again, but the way the i20 is reviewed is making me think again. After all, I could buy a 2 year old example quite cheaply, get rid
• Ford Focus - Cooling fan problems 30 Jul 2010 (Forum)
  although they have replaced the cooling fan, cooling fan module, temperature sensor and cooling fan relay. Unfortunately it still happens. They say it's a fault however can't find it. Its due to go back in for a new ECU. I have asked for a replacement vehicle as I feel this fault has gone on long enough
• VW Polo 03 1.2s - Engine warning light on for trivial problem 27 May 2010 (Forum)
  me over £27 in the end. How can it be right that the ECU retains the warning for a blown bulb permanently and doesn't clear it when I replace the bulb? Obviously I had to get the fault cleared as there's just the one warning light on this car, for everything from trivia to impending disaster

  have a 90 bhp Hdi of the same year, so I.................... 1 Swapped the low pressure Bosh pump in the tank, 2 Swapped the relay next to the ECU under the bonnet, 3 Done a like for like swap of the vacuum solenoids on the bulk head. SO TO SUMARISE, My 90 BHP now has all of the above parts fitted
• Ford Focus (1998 - 2004) - 99 1.6 cooling fan too keen 29 Jan 2010 (Forum)
  immediate fix but since then gauge seems to have stabilised by itself. New thermostat and cooling system flush to no avail, despite careful refill and bleed to avoid airlocks as before. Have disconnected battery for a few hours in attempt to let ECU self-reset but no change. If I arrive home with fan
• Peugeot 205 (1983 - 1997) - 91 1.6 Fuse Box/Fuel Pump Intermittent power failu 8 Dec 2009 (Forum)
  , fuel pump relay and ecu, the problem still persists, when the engine cuts out i proceed to 'wiggle' the fuse box itself whilst coasting down the road, and the majority of the time, this caues the fuel pump to start working, this fault must be caused by a loose or faulty connector on the loom, ofcourse
• Peugeot 306 (1993 - 2001) - 2001 HDi intermittent lack of power 10 Oct 2009 (Forum)
  it is in "limp" mode. I have just tried linking out the switch with a piece of wire which i thought would give me a fully performing car again, but this has not worked. Is the ECU clever, and expects the switch to break and make every time a gear change is done ? (i.e. when the throttle is released) Which
• Mazda 323 (1998 - 2003) - 01 1.6 Intermittent flashing engine check lamp 7 Aug 2009 (Forum)
  that the ECU stored the fault code, but perhaps I wrong! Has anyone had experience of this problem? Whilst I owned the car I had the engine check lamp come on and it was a defective knock sensor to blame (known 323 problem). Any help greatly appreciated...he's ripping his hair out in frustration
