• The end of rust? 4 Sep 2006 (Forum)
  Makes you think that if you look after the bodywork and service them regularly you can easily see 20+ years in a modern car. Probably an ECU or electrical fault too expensive to repair would not signal the trip to the scrappy rather than rotten chassis. I can it now, mixing the resin to do some fibreglassing at the weekend, and the fun in putting too much hardener in!
• Vectra overreving and kangarooing! 30 Mar 2006 (Forum)
  when I pull away.Plugs very sooty.Cleaned throttle chamber and all vacuum hoses,renewed Idle Control Valve,Air filter,h.t.leads and plugs.Renewed O2 sensor,changed coil pack for a known good one and renewed Temp sensor (to ECU)This fault is present hot or cold.No mil light comming on,so no faults stored (only have access to paperclip test)I cant find any Intake or exaust manifold leaks.Funny enough,I first put a second hand O2 sensor on and it ran fine for about 2 miles then back to normal(mil light did come on-Lambda Sensor Malfuntion).I thought it must have been on its last legs so I bought a brand new one-still missing etc but no light comming up.Anyone had this problem or knows of a fix please-I'v been on the Vauxaull Forums, seen similar faults but no fixes-Its doing my head in now!
• Help, flying oil cap. 1995 Skoda Favorit 11 Dec 2005 (Forum)
  Called breakdown to start it - firstly, managed to connect their starting battery the wrong way (smoke came out of his leads before he noticed) and then failed to start it mumbling probably the ECU or injector need replacing(?). Well, not trusting his competence, Hubby down to Halfords and a new battery. Tried to start again - was turning over much better but still didn't catch. Then, after a long period of trying the oil cap, I kid you not, flew a couple of feet away (plus puff of whitish smoke from oil cap hole).
• Another 306 diesel problem 3 Jun 2005 (Forum)
  This pump has been connected to the dead engine for about 6 months in the garage unused, is there a chance the valve has seized? What will happen if I fit the pump that was supplied with the engine? will the ecu communicate with it ok or will the solenoid remain closed because the codes dont match? Help please! Jon
• SAAB (mostly) cold starting problem 4 Jan 2005 (Forum)
  Does anyone have any other suggestions if changing the coil doesn't help? Apparently this one year does not have a feature connector on the ECU so they can't even plug it in and see if any faults have been registered... Does anyone know if there is any other way to find out? (I don't know what sort of injection but I can find out if necessary - I believe it's the newer B202 [?]
• Chipping etc 9 Dec 2004 (Forum)
  Likewise an Audi A4 TDi 130 Quattro tested at 147bhp in standard form, this being more than the 2WD TDi 130's, the comment is that the Quattro ECU is set differently to the 2WD by the factory. However a Rover 75CDT tested at 116bhp, spot on stanadrd spec. Makes me wonder how many cars are infact more powerful than that quoted by the manufacturer.
• Peugeot 106XR Quiksilver 19 Jul 2004 (Forum)
  I immediately contacted the garage once I finally got home and the car was collected by the garage. After 1 month I was told that the car was ready for me. During the period in the garage the ECU board was changed, the car was subjected to computer diagnostics at a Peugeot garage ( not the garage that I bought the car from) which showed no faults. The throttle sensor was also changed. When I finally got the car back it drove beautifully for about 150 miles, over a period of about 3 days, and then the same fault occured.

• VAG - EURO5 DPF info 6 May 2017 (Forum)
  Due to this soot is burned-off and is converted into a smaller amount of ash. Active ‘regeneration’ is when the ECU intervenes when the soot loading in the DPF is calculated to be 45%. The procedure lasts for about 5 – 10 minutes. Specific measures are taken by the ECU to raise the engine exhaust temperature to above 600°C, these include switching off the exhaust gas recirculation and increasing the fuel injection period to include a small injection after the main injection.

• Mazda 3 - Engine check light codes 15 Jan 2024 (Forum)
  A sensor fault i) The sensor's heater is faulty (burnt out) and it or the whole sensor needs replacing; ii) A grounding issue or 12V connection to the battery; iii) A wiring issue - often caused by heat (it's near the exhaust [where the sensor is] and CAT) and/or physical damage via some means or age-related. 3. A fault with the car's ECU. - - - - Any of the causes of the fault may put the ECU into a 'safe mode' for the air-fuel mix and lead to poor running or mpg and even possibly other faults if not fixed. Needless to say, the test drive (25 miles, 2x 12.5 mile trips within 2 hrs) did not register the fault again, and so I'm keeping an eye on it.
