  - even pollen filter (may as well !). But to no avail. Still hesitates just as bad. Any suggestions as to what could be causing this ? I have also used redex petrol & injector treatments too - still no change. BTW simos ecu, is dealership diagnostics next step ? Thanks in advance...
• SuperChips - Have you used or heard of? 28 Apr 2005 (Forum)
  Has anyone used or heard of the company called SuperChips? Basically what they do is re-program your ECU to improve performance etc. NB: I have a dual fuel Vectra which simply doesn't run quite as smoothly when running on LPG compared to petrol (new plugs and leads helped a bit but didn't

• driving a tacho 9 Jan 2005 (Forum)
  OK, bit of a general question so havent put any make/model. I need to find a suitable signal to drive a rev counter (aftermarket). I know on a petrol this would drive off the coil or ignition module / ecu. The car its going in has neither. I have been told before it will drive off the 'w' terminal
• Primera 1.6i idle speed 23 Dec 2004 (Forum)
  as there are no marks on the tacho between 0 and 1000. In both cases it idles perfectly stable, never stalled. ECU also seems to do its job correctly by slightly upping rpms if a/c is turned on. I wonder if this was a mistake made by a dealer who did the last service (that was before I bought the car), i.e. he

• Transit connect TDCI problems 2 Mar 2004 (Forum)
  Hi, My mate has not seen his year old transit connect for the last 6 weeks as it has been stuck in the local Ford dealer for repairs. The fault is intermitent yellow glow plug light and then lack of power as it goes in limp mode. Ford have changed the fuel pump, put 2 lots of injectors in, new ecu
• VW Passat Tdi110 Loosing Power 19 Dec 2003 (Forum)
  My sons Tdi 110 with AFN engine looses power. If you accelerate hard in say 3rd gear, as the rev counter reaches about 3000rpm, which must be about maximum boost pressure from the turbo, the engine looses power as though the turbo had been disconnected. I suspect the ECU has detected a problem
• Mono-Motronic Audi/Pug/Citroen 19 Feb 2003 (Forum)
  and they had loads of 'em, so there's the tip; Mr Bosch used the same parts all over the place, if yours appears rare, try another manufacturer. A quick question, despite the instructions on my Gunson FCR quoting my engine code (ABT), why can't I pull the fault codes from the ECU? Any other way of getting
• Golf MkIII Diesel - Starting problem 22 Nov 2002 (Forum)
  . However once started to trip computer displayed 'OEL'. This happened having started the car, driven several miles and then parking for 10 minutes. It wouldn't seem to be a battery problem, so am guessing possibly an earth or ECU problem. Has anybody else had this problem or can suggest where to start
• BMW ABS WARNING LIGHT. 24 Oct 2002 (Forum)
  to find out what the actual problem was I would have to take it to a BMW dealer and have it put on there computer (at the current cost of a BMW technicians time). I found some info on a website saying that BMW ABS problems are usually to do with a sticky ABS pump motor relay, wheel sensor or the ABS ECU
• Vauxhall Corsa C 1.7 DI GLS - Lack of Power/Gutless 18 Oct 2011 (Forum)
  . 11. The Technician suggested it could be the ECU, the fuel pump or maybe the injectors. I found a guy on eBay that re-programmes second hand ECU’s to your car at £200 and as I described the fault he thought that it was the ECU at fault and would change it and if this was not the fault he
• Peugeot 806 MPV (1995 - 2003) - 01 2.0 Fuel pressure sensor fault 21 Jan 2010 (Forum)
  cannot re-start the car straight away as you have to wait for the ecu to turn on the fuel lift pump (the one that sits in the tank) which can take 30 secs once the car has cut out. You can hear a relay switch on the right handside of the engine bay and then the fuel lift pump comes on and the car starts
• Toyota Starlet - Coolant temperature sensor and temperature gauge 31 Mar 2022 (Forum)
  for the ECU and one for the gauge. Which suggests that the ECU thermistor on the new sensor is OK but the gauge one is not. I'm not sure if it's faulty or just the wrong model
• Nissan Qashqai - Qashqai, loss of power, alarm going off etc 29 Mar 2020 (Forum)
  that is happening. So basically the car thinks nothing is wrong with it. Nissan Garage already saying they may not be able to fix it. Everything I suggest like fuel pressure ECU etc they just dismiss, yet can give me no idea at all as to what is wrong - not even suggest when asked. They did try banging on about
• Audi A4 B6 - Stuttering engine then stall - 2004 1.9 TDI 23 Apr 2019 (Forum)
  in relays under ECU which caused limp mode plus soaked carpets inside drivers and rear passenger behind driver side. Cleared blockage and dried out relays and all appeared good. 2 days later I got CEL light and code P0230 but car still ran fine. 3 days after this, as I was arriving home
