• Ford focus engine warning light 5 Mar 2006 (Forum)
  The car ran fine for a while but now the engine warning light is coming on again. He has taken it to the ford dealership who hooked it up to the ECU analyzer and told him the catalytic converter needed replacing, however, it passed its MOT with flying colours on the emissions test 2 weeks ago. Is there any way that the catalytic converter could actually have degraded so badly in two weeks or is it more likely that there is an issue with water/moisture in some sensor connector giving a false result to the ECU, if so which sensor is the likely culprit?
• Renault Clio 1.4RT 98> 25 Jul 2005 (Forum)
  Peeps, been having intermittant problem for far too long now, i'll explain: My clio 1.4RT runs fine, starts fine, all ECU sensors fine. However if you go out for a run and the engine gets hot, then you sit on low idle for a while (for example sitting in a queue for a car park, far to often where I live) the ECU "dumps" its throttle setting and starts to Idle at 1400rpm.
• Superchip's Bluefin 5 Mar 2003 (Forum)
  Has anyone had any experience of the Superchip Bluefin, this is a small device similar to the diagnostic kits that plug into your ECU and give you a view of whatever error it might have. The difference in that case is that (as well as doing the above), it will also change the settings on your ECU to increase performance etc (A DIY chip upgrade).
• Alfa 156 Selespeed Gearloss 21 Mar 2002 (Forum)
  The loss of gears occurs at any time, warm or cold, stationary,pulling away or cruising I calculate the dealer (under warranty) has received the car around 15 times - 6 of which were tow ins. I have had a new gearbox, lower ECU, higher ECU, gear box oil pump, numerous diagnostics. Apart from training the children to operate the hazard warning lights has anybody had and cured a similar problem. P.S. Am I the only one having major problems with "service" at Reg Vardy's - and can anyone explain to them what a courtesy cars is ??

• Ford Focus Zetec - ECU failure not covered by warranty 21 Mar 2018 (Forum)
  It was taken to Liss Garage Services, who have been servicing and repairing our family’s vehicles for many years.  Stewart Roberts, the proprietor, suspected a problem with either the ECU or a fuel injector, but told me that the engine was so badly damaged that it would need replacing, which he did at a cost of over £3,000. On testing the car following this, the replacement engine failed and a third engine was installed.
