• Citroen C3 (2002 - 2009) - 03 1.4 16v ECU failure 13 Dec 2009 (Forum)
  Hi, C3 Diesel 1.4, 16v HDi, 92hp. 3 yrs 10mths old 55K miles, looked after, shell diesel fuel only etc. Citroen UK are 99% certain that the ecu has gone duff. £852 inc vat for a new one!

• Mercedes CDi poor performance 16 Feb 2003 (Forum)

• Ford KA, KA2, KA3 (1996 - 2008) - 2003 - Remove ECU. 8 May 2019 (Forum)
  Hi Guys. Does anyone know how to remove the ECU from a 2003 Ford KA? From what I can see it looks like you need to remove the whole dash! Surely that's not right! On that note, does anyone know how to remove the dash. I located a couple of bolts behind platic covers on the door sill, and one bolt behind the platic cover on top of the dash on the passenger side, and although the dash is looser, it still doesn't want to go anywhere.

• Nissan Navara 2.5 - Nissan Navara 2.5 which is failing to start 12 Apr 2010 (Forum)
  Hi, I have a Nissan Navara 2.5 which is failing to start, the engine turns over but there is a stored fault code "E1 NATS Malfunction"  I suspect the immobiliser unit is not picking up the transponder signal from the key or it is not signalling the engine ECU with the correct information? (Faulty Immobiliser)  If the car has a fuel cut-off solenoid at the rear of the injector pump is there a way of energising this to (allow operation) from the wiring into / out of the PCM/ECU?

  Hi Everyone, We have an 03 (Oct reg) Mondeo estate TDCi 130 that is an ex-fleet car that we purchased from an independent trader (non local) last november. We are happy with the car and have had no problems. I have read on this forum however than an ECU update was available that boosted fuel economy and improved performance.

  I took it back to the formentioned reptutable garage and the problem has now turned out to be a knackered ECU, which they are wanting the best part of £1500 to replace...parts and labour My question is, do I have any rights as a consumer to question/claim the garage as liable for the damage as what WAS an intermittent fault is now a permanent one?

• Mini One 2003 - ECU Battery? 21 Feb 2016 (Forum)
  They refused to fit an isolator switch to enable me to stop the fault from draining the battery when the car is not in use. Their reason being that "they think" the ECU has a back up battery so I will only wear that down if the main car battery is disconnected. Does any one know if a Mini One 2003 contains a back up battery within the ECU?? Or are they just trying to get me to spend the money on a new latch?
• Vauxhall Corsa D 56 Plate - ECU Problems 22 Jun 2015 (Forum)
  Fitted that, no joy, 2nd hand fuel pump, no joy, 2nd hand throttle body, still no joy. Off to auto electrician diagnosed ECU failure. After 2 attempts with another auto electrician installing and re programming ECU still no joy. Car will fire up and then just cuts out. In the 2 years I've had it, it has started and run every time without failure a few times the battery has gone flat, but always started with jump leads.
