• Storing fuel injectors 7 Oct 2002 (Forum)
  I have just had a Saab performance upgrade kit fitted to my 2.0 Saab 9-5 which consists of a new ECU plus a set of different fuel injectors. I plan on keeping the old ECU and injectors in case I decide to migrate back to the original setup (e.g. on change of car). My question is, what is the best way to store the injectors to avoid any problems when they are refitted (if ever)?
• Mondeo 1.8 Pinking 16 Jan 2002 (Forum)
  Further to a thread in the past my 99 Mondeo 1.8 is still pinking on normal unleaded (fine on optimax) I have replaced the plugs and HT leads, ran three doses of VAG fuel additive through the system and reset the ecu by disconnecting the battery for half a day. Incidentally, since disconnecting the battery and resetting the ECU the pinking seems to be worse (I might be imagining it though.) The pinking occurs mainly at 30mph in fourth gear when I floor the throttle.
• 05 model - Volvo 50 diesel estate 14 Mar 2015 (Forum)
  Next morning car would not start at all. Towed to local garage who spent three weeks looking at it, they thought it was an ecu issue. Car towed to main dealer who after one week also said it was likely to be ecu issue but they couldn't be certain as may need new throttle. Cost for new ecu extortionate and as delayer could not be certain I was not prepared to write an open cheque.

• Volkswagen Polo III (1994 - 1999) - 1998 1.6 Engine cuts out and will not start 10 Mar 2011 (Forum)
  A local garage read the fault codes and these showed problem on all 4 injectors, but as garage said it is unlikely they are all playing up, they also cleaned throttle body but could find no other faults. The garage did suggest it may be an ecu fault or wiring problem. I did speak to an ecu repair specialist who thought it was not likely to be ecu as they have no ability to self repair like the symptoms would suggest, but rather was a wiring or relay problem.

• Citroen ZX (1992 - 1998) - 1991 1.9i petrol Engine problems 2 Jun 2008 (Forum)
  The mobile mechanic put an indicator box on one of the plug leads, and earth, the car started and ran until the engine was turned off, there were sparks jumping across the coil leads to ground, replaced the coil and amplifier, engine will not start, had the ECU checked by a garage, 14 faults registered, sent ECU away to be checked, OK no problem with the ECU. There is no spark at the plugs or fuel into the injectors when the engine is turned over with the ignition on.
• BMW e36 318iS engine cutting out 11 Jul 2003 (Forum)
  Two questions. 1) Any experience/advise on what might be causing the problem and best PD method ? 2) This is the first time I have had a problem with an ECU controlled car. I have always been able to resolve problems on older cars, but feel somewhat at arms length without access to the failure codes out of the ECU. I have been looking for ECU readout equipment online, but there doesn't seem much available for the home user.
• ECU/ Diesel ! 14 Apr 2003 (Forum)
  Four miles...it started cutting in and out (again inc rev counter flicking on/ off)- I parked up, ten minutes later started fine and drove home. Is it an ECU thingy problem ?? If so where located/ how many of them/ where to get one ?. LAST question - I `like` diesels, and would wish to convert the car. Which would be the best/ simplest diesel conversion ??
• Vauxhall Calibra V6 Auto 4 Feb 2001 (Forum)
  I reported the problem to my local dealer and when they attempted to diagnose they were unable to read from the ECU. They advised that the ECU unit would need to replaced before any further diagnosis. I was discussing the problem with a friend who suggested that this might be a simple problem of low fluid levels in the automatic gearbox.
• MAZDA 3 1.6 PETROL 2010 TS2 - abs LIGHT 4 Jun 2018 (Forum)
  At first it was intermittent but eventual stayed on permanently. My local garage checked all the wires and found no fault. They then sent the ECU away for examination and they could find no fasult. When the ECU was refitted the light remained off for approx five days but is back on again. There was a recent 24 hour period when it did not come on.
