• Vauxhall Zafira - ecu problem 15 Jul 2011 (Forum)
  I have a i.6 zafira 2001 the engine light came on the dash a while ago and i had a friend check the codes with his snapon reader, it came up lamba sensor, hed removed the codes and all seemed to be well a day or two later the engine seemed to be running a little lumpy and the rev counter stopped working also the cooling fan kept running all the time although the engine was not hot at all, then the next day it would not start at all , my friend did another check with his reader but it came up with an error message " conection failed, we tryed several times but cannot seem to connect to ecu , does this mean my ecu is shot? Would anyone have any ideas on whats causing this problem please, I would be most grateful if anyone could help before i splash out on a new ecu, many thanks
• Vauxhall - Vivaro - 03 1.9 ECU location and removal 20 Jan 2009 (Forum)
  (dont have a clue how they have managed that one as it was only in for a week!!!) a Vauxhall dealer has told us it was the ECU so im going to take it out and send it away myself to get sorted as its much cheaper than they have quoted. The van is still in the garage but im just going to go and get the ECU out myself, so want to do it as quick as possible.
• Renault Laguna II (2001 - 2007) - 2001 1.6 ECU problems 13 Aug 2008 (Forum)
  Should this screw have been adjusted as I believe it is factory set and surely the ECU controls the idle speed? Could this adjustment have caused an ECU fault? Anyone had a similar problem? Appreciate any help. Cheers!
• mpg and 'learning' ECUs 26 Sep 2006 (Forum)
  The thread by Westpig got me thinking. In modern ECUs, some of which are purported to be of the 'learning' type, how long does it take for fuel consumption to stabilize at the new driving style? If my Mondeo TDCi 5-speed has such an ECU (correct me if I'm wrong), then I have this evidence: If only I use the car for commuting for several tank-fulls, I will get just over 50 mpg.

• Toyota Yaris - DPF cleaning require ECU reprogramming ? 27 Aug 2016 (Forum)
  Does anyone knows if the Toyota ECU require rreprogramming to reset the DPF loading level after the DPF is cleaned? I have asked one of the DPF cleaner garage and they are unsure. They are charging £200 to remove, cleaned and refit to the car.

• ECU reset on Laguna - Dealer only? 1 Mar 2005 (Forum)
  Took my Laguna to the garage today as airbag light is continually on - abs has switched itself off so that light is now on as well. They diagnosed a fault with the ecu and advised me to take car to a Renault dealer to be reset. Is going to the dealer my only option and if so, how much do you reckon it might cost? Thanks

• Vauxhall Meriva B 2011 - New airbag ECU - advice needed 16 May 2012 (Forum)
  I have a Vauxhall Meriva B 2011 that isn't under warranty. The airbag light was on so I sent the ECU away to have the crash data cleared - but it was lost in the post. I bought a new ECU new from Vauxhall but I think this has to be re-programmed to the car. This is where I get confused with what to do next.
• 2002 Laguna faulty ecu connector block 31 Dec 2006 (Forum)
  So my question is.... is this possible, or do some of these wires have built in resistances where the values may change and upset the ecu? (even if the wires are the same lengths?) Your help is much appreciated. Thanks
• Corsa 1.4 ecu fault codes 12 Jun 2003 (Forum)
  Hi - Can anyone please help? Have a 98 Corsa 1.4 single point injection 38000 miles- (all short journeys) ECU light has just started illuminating each journey after about a mile. Can I read the fault codes in any way without buying a gismo? I seem to remember being able to do this with a cavalier- by shorting terminals in the diagnosis port you could read the fault codes from the number of flashes on the dashboard ecu light?
• Vauxhall Astra G Petrol 1.4 16V (2001) - Astra G 1.4 16V Petrol (2001) questions. 15 Oct 2014 (Forum)
  So I can find out the correct part numbers I need for the replacement parts I need including the correct part number for the ECU unit I need. Could the ECU its has fitted be flashed to a 1.4? because the ECU fitted is for a 1.6 not  1.4. would this mean the ECU could give out incorrect fault codes? Qould I have to but A qhole new ECU kit. or could I buy only the main ECU unit. then re-use the other parts (tranasponder etc) to work with a new 1.4 ecu?

• Mitsubishi Carisma (1995 - 2004) - Where do they hide the ECU in a 04 1.9 D-1D 29 Nov 2007 (Forum)
  I have a 2004 Mitsubishi Carisma 1.9 Turbo Diesel Where is the ecu? I've looked in the engine bay,under the dash and removed the centre console. Have i missed the obvious? (probably!) Hope someone has some ideas :)
• Peugeot 306 meridian (S) misfire 15 Apr 2021 (Forum)
  Has anyone experienced similar problems, and have these been rectified by replacing or reprogramming the ECU? I suspect a fuel pump or ignition electrics problem could also be possible and I see many people mention coils affecting the ECU can I discount any of these? In addition if a new ECU is required is it particularly unwise to try and pick one of these up from a scrap dealer?
• Citroen C3 1.4 Auto 2002. KFV Engine - BSI Dead / ECU Replace 7 Sep 2014 (Forum)
  E.g. Wipers, light, radio post, speedo etc. i'm looking at replacing the bsi unit along with an ecu and transponder set, but my ECU is sagem. I can't find anywhere another Sagem ECU with the bsi and transponder set. But I can find bosch, Magneti Marelli and Siemens sets. The BSI and fuse board is Siemens.
