• Peugeot 307 HDi 110 52 plate - Diesel additive at minimum level 12 May 2012 (Forum)
  Ive read a few threads on here and i think i'm going to buy the refill kit and take it in to get the ecu reset. I'm a hgv mechanic and am i right in thinking its the same as an add-blue system on a wagon? Add-blue sysytems just inject add-blue (pig p***) into the exhaust cat to reduce emissions. My main question is if i leave it will the engine go into limp mode and could leaving it cause any damage?
• Ford Fiesta - Ford Fiesta 1.4TDCI EAC FAULT 20 Mar 2012 (Forum)
  Hi, am new to this and need some help with my  ford fiesta 1.4tdci its driving  me crazy, It all started when I changed my Injectors after changing my injectors my turbo failed to work there was no EAC fault coming up on the dash, just the the turbo would not kick in. After rebuilding the ECU turbo worked fine but there was another problem the EAC LIGHT flashes on the dash and the battery  light is very dim. Am assuming its down to the battery light i think it may be alternator or PCM module wire ..
• Vauxhall Vectra B, Jan 2002 - Service Light 27 Feb 2012 (Forum)
  I had the car serviced only last September, so it isn't in need of a service. I'm told it could be because I have changed the ECU ? Any suggestions or help will be greatly appreciated, as it is a real pain.

• Vauxhall Vectra B 2002 Z18XE - Loss of power 3 Feb 2012 (Forum)

• Disconnect battery to trickle charge? 20 Jan 2012 (Forum)
  Is it vital to disconnect the battery during charging or will the vehicle cope OK, i'm fairly sure the engine management ECU has to 'relearn' following reconnection but i may well be totally wrong. The car is running so perfectly i'd rather not disconnect if possible. Whats the proper procedure?
• Golf 1.6 auto 2002 - Won't start from hot or after short journeys 2 Aug 2011 (Forum)
    I've spent so much but I am ready to admit defeat.  Could it be anything to do with the ECU sensor or wiring (?), read something on the internet.  Please can someone help!  Thank you

• Rover 75 CDT - ABS Problem 5 Apr 2011 (Forum)
  From start up and moving off the ABS system kicks in then after about a minute it goes off and the light appears on the dash, normal braking but no ABS, changed the front two wheel sensors but no difference.Car has done 160,000 so i'm guessing now it's a more serious problem, i don't think it's the pump but in the book it shows ECU attached to side of the pump so i was wondering if anyone else has have a similar problem with either the Rover 75 or cars with similar ABS systems at can point me in the right direction, would a plug in at the garage indicate with a fault code what the failure is?
• Vauxhall Vectra C - Battery Drain 26 Jan 2011 (Forum)
  Tested for a drain using my multimeter in  series with the battery earth cable, doors locked, waited for the ecu to close down, and got a read of 0.2 on the 10A setting. Am I right in thinking this current draw is too high? I read somewhere to expect 0.05 maximum, otherwise it might be a diode fault in the alternator?
• saxo furio 2002 - Lambda sensor problem or not? 8 Nov 2010 (Forum)
   Please can someone tell me the least expensive way of diagnosing whether i have a fault with sensor 1 sensor  2 or the cat itself. The ecu light has been on and diagnosed  vaguely by the garage as the emmisions but these have been tested separately to be ok. i can do the work myself i think as i have already removed the post cat sensor thinking i might sleeve  it it as mentioned elsewhere but am not sure if that will work or even if its legal.

• Ford Mondeo III (2000 - 2007) - 03 2000 tdci injector coding, can anyone help me? 5 Feb 2010 (Forum)
  my glow plug light is flashing and my 130bhp mondeo is underpowered. Im certain its a faulty injector, but i think maybe the ECU has lost the code, and it can be recoded. What software would i need to do this myself? Or does anyone have it and can do it for cash? I dont want to take it to ford because i would rather pay an enthusiast.
• Peugeot 206 hatchback (1998 - 2006) - 01 2.0 HDI remap to 150bhp safe? 8 Jun 2009 (Forum)
  I have had my 206 ECU remapped to 120bhp by someone. When he remapped it, he said it could've been done to 150bhp, but it would've wrecked the clutch and I would have had repair bills every week. However, after speaking to a Peugeot mechanic today, he said it wouldnt be a problem as he has seen one done and he said it drives well.
• Mercedes Benz C-Class W202 (1993 - 2000) - C class 240 27 May 2009 (Forum)
  It has done 100k+ miles but looks in good condition. I am concerned about reliability. The review on this site says the ecu can fail after 12 years and can't be fixed - the car is a 99 so 2 more years? Plus, there are also potential rust issues, it doesn't drive as well as the previous model. I've always like the classic solid look of the older mercs (esp c class).
• Peugeot 406 (1996 - 1998) - 98 2.0 Misfire/stalling 20 May 2009 (Forum)
  Any ideas as to the next steps I should take would be much appreciated as the mechanic seems to think it may mean a new ECU (ouch) which I would like to avoid if possible
• BMW 3-Series E46 (1998 - 2005) - 02 2.0 diesel - fuel timing question 15 Apr 2009 (Forum)
  I was about to check the piston/valve clearances on a dry build when something occurred to me. The crankshaft has a position sensor but I can't see one for the camshaft. How does the ecu know that it should be injecting at the end of a compression stroke TDC for a particular cylinder rather than the exhaust/inlet TDC? Sorry if this is a bit long winded but how do I know it will not be 1 crank turn out of sequence?
• Toyota RAV-4 (1994 - 2000) - 94 2.0 Immobiliser removal and loss of ignition 9 Apr 2009 (Forum)
  I have removed the 918T ECU unit from my Rav 4.First I could not run the starter motor until I was told to connect together the leads going to Pins 14 & 15 on the 15 pin socket. Others may be interested in this as it took me a while to find this out.
• Peugeot 306 (1993 - 2001) - 1999 2.0 hdi very very poor mpg 7 Mar 2009 (Forum)
  Iv'e checked for leaks and there arnt any. The other day i had it diagnosed by an electrician with a modis first it showed ecu error he then cleared it and told me that the egr is not working shows no othr fault codes apart from a break in the glow plug circuit which is strange as it starts fine. I have had the fuel rail changed a couple of months ago as it developed a leak other than this no other parts or sensors have been changed.
