• Range Rover Classic 4.2LSE 18 Aug 2004 (Forum)
  If gas, can I get away with fitting an exhaust pipe minus the cats? I intend to fit tubular headers with lambda fittings. As the probes are upstream of the cats the ECU will not know whether they are fitted or not.
• Opel or Vauxhall 15 Dec 2003 (Forum)
  What are the differnces between the Opel and Vauxhall Corsa? Is it just the badges or are there differences to the engines, ECUs etc? I am worried that if we break down in France, will the Opel dealer be able to deal with a Vauxhall? Will their diagnostics be able to read Vauxhall codes etc?
• Memory Savers 29 Oct 2003 (Forum)
  To do this I need to remove the alternator, and of course disconnect the battery. I have heard that memory saving devices are available to save the cars ECU settings. Are they really necessary? and if so what devices are available to the DIY\'er? Your advice please. Regards Andrew

• Omega Power Steering 8 Oct 2001 (Forum)
  The Haynes manual for the Omega says that there is a sensor to detect when additional load is being placed on the engine by the power steering pump - i.e. on full lock. This is only for V6 cars fitted with the Motronic 2.8.3 ECU and gives a few extra rpm to the tickover to prevent stalling. My question is - where is this sensor located? The manual makes no reference to its location.

• 51 Toyota Avensis 2.0 VVT-I Auto - Running rich/low idle 23 Jul 2018 (Forum)
  Mpg has improved after the Cataclean. I just can't work out why there's this low tick over until the engine is hot. It seems that the ecu is confused after it goes closed loop. It must be a sensor of some kind but I can't figure out which one it could be. I'm worried about failing the MOT and ruining the Catalysts. Any ideas please? Cheers

• Mazda 3 - Engine hesitation 6 Jan 2015 (Forum)
  I can "override" the factory set idle speed to mimic the cold running speed, but this of course totally upsets the ECU and so isn't a way forward. I understand that the throttle and clutch are linked by microswitches and was wondering if there was a fault with either/both of these switches, or maybe something in the ECU itself.

• Fiat stilo - Fiat stilo immobiliser 18 Jun 2013 (Forum)
  I can't believe that it has happened again. The garage gave me no paperwork last year regarding putting in a new ecu unit. Where do I stand with regard to the work they done? Surely the car which I have only had for just over a year was not fit for purpose when they sold it to me?
• Ford Mondeo IV (2007 - ) - 2.0 TDCi -- Oil Service message. 22 May 2013 (Forum)
  Rang the supplying Ford main dealer (very helpful on this matter) and they told me it's a known problem. The fix is an oil & filter change and an ECU update, they say. The service manager says it's an oversensitive sensor relating to the DPF, which reports the oil has become contaminated and is putting the DPF at risk. The ECU update is supposed to reset the parameters for the sensor.
