Left the battery removed overnight. 7. Checked immobiliser fuse and it is intact All of these did not work , run out of ideas, Should I track down the ignition immobiliser and see if it is defective.
• Toyota Celica (2000 - 2007) - 00 1.8 Window Wiper / Washers problem 4 Dec 2010 (Forum)
  Front window wipers switch on for no reason whatsoever even when they are on intermittent, they go to normal sweep, also my windscreen washers are not working front and rear, checked fuses, all seems in order, thought it may be the wiper stalk so managed to take it apart, all contacts seemed ok, cleaned it up and away I went, scooshers still didnt work then 5 mins into journey wipers switched on.... aaaahhhhh Purchased a used wiper stalk on ebay cos a new one from the dealer is a small fortune, same happened again, now unless I am extremely unlucky and have 2 faulty stalks I am thinking its the pump (cant find one on ebay and not buying from dealer)...but why is it shorting the wiper..... or is it the ecu? has anyone had this problem or can anyone help, thanks
• ford focus estate tdci 115 03 - rough running focus that garage cant explain! 7 Nov 2010 (Forum)
  hi not sure if anybody can shed any light as my local garage dont have a clue! my focus started playing up about 4 months ago so i took it to my local garage to get the ecu read. the fault stored said the waste gate solenoid was at fault and so changed but this did not solve the problem. 4 months on and they still dont know what is wrong. it starts and runs fine for about 2 mins but then runs lumpy and rough and will not rev past 2000rpm and kicks out a hell of alot of smoke as a result. if it is switched off and restarted straight away it will run fine again for a few mins and then starts running rough again. i suspect injectors but it is an expensive trial and error, and have lost faith in my local garage.
• Ford Fiesta 1.25 Zetec-SE 2000 - Fiesta running lumpy and down on power. 31 Oct 2010 (Forum)
  I have been reading similar problems on the internet which mention lambada sensors, MAF sensors, ECU's. Can't work it out! Any help would be greatly appreciated. Thanks
• BMW E34 cold start problem 12 Oct 2010 (Forum)
  Help please 1990 520i with 88000 mls and full BM service history,for the last 3 months is very difficult to start first thing in the morning. 3 visits to BMW and 3 further visits to BMW specialist has failed to resolve the problem,in fact it is getting worse. At first they said it needed a full service - no improvement,then it was a faulty ECU unit,had this replaced - it did not resolve anything,then they replaced the thermotime switch which apparently controls the cold start injector - no difference at all,and finally the filter on the fuel line (it must be partially blocked)the car has still got the original problem.They now admit that they do not know what the problem is.

• Ford C-MAX (2003 - 2010) - 03 1.8 Unstable Idle when slowing 17 Feb 2010 (Forum)
  The problem has gotten worse over time and now the car is nearly stalling with the battery light coming on. I have scanned the ECU for but there are none registered. The car is also often a pain to start normally when been standing overnight the car will start then the rev's just drop off to 0 causing a stall. I was wondering if anyone on here has had this problem before I start spending £££'s on parts that do not need changing.
• Peugeot 307 (2001 - 2007) - 02 2.0 diesel. HDi Limpmode 21 Jan 2010 (Forum)

• Renault Scenic (1999 - 2003) - 99 1.6 failing to start MK 1 10 Jan 2010 (Forum)
  The only thing I did notice when I first checked it was the water level in the header tank was fairly low, there is no water in the oil or cylinders and the engine temperature was indicating normal with no change in performance(is there a engine cut off if the water level gets to low) any thing else I can check before I have to get the ecu read thanks
• Volkswagen Passat (2001 - 2005) - 06 1.9 Hydro hybrid fuel improvement for better mp 18 Dec 2009 (Forum)
  Does anyone have any experience of how well these work and if they last? For an investment of several hundred pounds (including the EECU to combat my ECU) I think I'm looking at a 2 year payback if I get 20% imporvement in fuel efficiency (25,000 miles and £1.05/l) Has anyone had any insurance issues? Are they removable to move to a replacement car when the current one finally pack in, hopefully in 8-10 years more at least.
• Peugeot 306 (1993 - 2001) - 98 1.6 wont start 24 Oct 2009 (Forum)
  had a look at my friends 306 as the electric windows wernt working, i disconnected the battery and began to search for the problem, i noticed a fuse had blown and a few wires had broken, i put in a new fuse and reconnected the wires and the windows worked fine. i then reconnected the battery and tried to start the car but it wouldnt go and the central locking had stopped working. i looked in my haines manual as i didnt no where to start i followed the instructions and cleaned and sprayed all the connections with wd40. i then took one of the plugs out came to find there was no spark. ive was told the immobiliser had shut and wasnt allowing the ecu to send power and cause a spark becuase the key wasnt being recognised. so i tried the spare but still no joy. just wondered if anyone had any idea as my friend is desperate for the car. many thanks.
• Volvo 850 (1992 - 1996) - How important is ABS? 8 Jul 2009 (Forum)
  Hi all, I recently picked up an 850 T5 estate. I'm in the process of repairing the ABS ECU (a known fault with this model- dry joints need resoldering), and consequently the ABS is disabled at the moment. I'm hoping to have it done and refitted by the weekend, but things are rather busy at the moment and that might not happen.
• Volkswagen Golf V (2004 - 2008) - 06 1.4 abs esp arrr! 28 Jun 2009 (Forum)
  This is a regular problem with VW cars I am told . I read on a forum that turning the ignition on and off many times should clear the fault and ecu will eventually recognise the new ABS pump.
• Subaru Forester II (2002 - ) - 02 2.0 Cutting out 31 Jan 2009 (Forum)
  It has been regulary serviced and I have recently swopped the sensors from another vehicle and the fault persists. No code is held in the ECU and only once has the engine management light briefly appeared but the memory holds no info? The car has been fitted with an inline computer whilst driving and this again shows as no fault.
• Vauxhall Astra F (1991 - 1998) - 1998 1.6 Engine Revs by itself 23 Jan 2009 (Forum)
  There is the throttle position sensor by the linkage and I am wondering if this could be the problem or is it the ECU ? Any other suggestions would be welcome as everyone that I have spoken to does not have any idea.
• Ford Focus (1998 - 2004) - 04 1.8 Slightly Poor Fuel Consumption 18 Dec 2008 (Forum)
  I have had an engine tuning (proper tuning, not boy racer job) to try and improve the fuel economy. The ECU settings were changed and new spark plugs were fitted. It has made a different to engine, feels a lot smoother, but the economy hasn't really changed. Anyone got any tips of what modifications i could possibly do to improve the economy.
• Ford C-MAX (2003 - 2010) - C-Max 1.6 TDCI engine cut out 13 Dec 2008 (Forum)
  She ALWAYS restarts after cut out and electrics do not seem to be affected. Is this a sensor issue (throttle?), ECU update issue or Fuel Pump issue, my local mechanic has tested the system twice and a fuel pressure problem appears (among others), the filter has been changed by him, but not fixed problem. PLEASE HELP, D

  If warm and i stop the engine it starts again fine. Economy is unchanged and recent full service has made no difference. No codes to read from ECU so i am wondering if anyone has any ideas? thanks
