• Mazda 2 - Remap? 4 May 2022 (Forum)
  It's reasonably nippy for a car in this category, with a 0-62 of 9.4 (if you give it some revs - no turbo). However... https://www.mybluefin.co.uk/Details/ECU-Remap/Mazda/Mazda2-MK4-2014/Petrol/Sport1-5-89-bhp/stage-1 An extra 39bhp! Plus a not quite so impressive 11Nm (8lbft?). And don't forget the improved economy :) Funnily enough the max power/torque figures are the same for all 3 versions (and other companies offer identical improvements).
• Take me back 23 Jun 2021 (Forum)
  I hate all the unnecessary electronic gubbins that are fitted to even the smallest of cars these days. Bluetooth this, hands free that, twenty ECU’s, numb electric steering and hugely complex automated manual gearbox all with an almost certain gargantuan bill for repair at the other end. My wife’s Volvo is full of complex electronics that fill me with fear and are never used by me if I can avoid it.
• Mazda 3 - mazda 3 1.6 diesel oil temp minus 40? 1 Nov 2019 (Forum)
  I have managed to do a manual re-gen and clear the DPF out, the problem i am having is that the oil temp is saying minus 40. i think that because the ECU is getting the reading of minus 40 degrees the DPF will not re-generate its self. my first thought was that the oil temp gauge was faulty, but i cant seem to find where the oil temp gauge is. i thought it may have been in the oil pressure switch but that only has one wire from it which i think just tells the computer weather the switch is on or off. does anyone know where the oil temperature reading comes from?
• Corsa D - Lack of power/chugging/ 21 Jun 2019 (Forum)
  - Blocked up exhaust - Burnt out valves - Clean up the throttle butterfly - EGR valve (hesitation at light throttle) - Connections to ECU (damp, or oil residue from changed filter) - Loose bolts around bell housing (causing electrical fault) - Camshaft sensor (jerking at constant speed, loss of power when idle/neutral) - Any other electrical fault?
• Honda Jazz 2016 - Starting problem - Battery / charging system 30 Mar 2018 (Forum)
  I mentioned to the service team with the above information and told me not to measure the battery voltage with a multimeter as this could damage the ECU and charging system. Is this possible?? Honda uses smart charging system, but the voltage seems variable from my observation being anything low as 9v to 14.9v. Not sure if this is normal. So please advise if this is normal.
• Jaguar X-Type Estate (2004 - 2007) - 04 2.0D Engine cuts out..... 20 Oct 2017 (Forum)
  That makes me suspect that the main fuel pump could be faulty, or some other sensor which leads to the ECU switching the pump off. Then it started again. I checked the connections on the main fuel pump and on the fuel pressure sensor. Needless to say it broke down again after another 3 miles. Any ideas gratefully received......
• Peugeot 307 CC - Peugeot 307 intermittent starting problems 28 Jun 2017 (Forum)
  The car is used quite a lot, probably 5-10 trips a day. So ~90% of the time it always runs fine. I've read the ECU, nothing major jumped out aside from a P0106 fault (which may or may not be related). I've double checked that all air pipes are looking good - no sign of any cracks/leaks/etc. The car was last serviced by a Peugeot dealer in October 16.
• Ford Fiesta (2002 - 2008) - 2003 1.4 Cutting out low idle revs 25 Mar 2017 (Forum)
  If I press the clutch in at any time or put it in neural the revs fall and it idles normally. There is no engine light on and no other faults whatsoever. I?m thinking the ecu has a problem with the new coil or was affected by the old one, or an air leak somewhere. Either way I want to pinpoint the problem myself to avoid paying the local dealer to look at it then tell me its fine because there are no fault codes!
• Puegot Boxer Van 2L petrol 1997 - Problems after Cam Belt Change 11 Feb 2016 (Forum)
  It did this for 5 minutes then started running ok  mechanic reckoned he spent 4 hours fault finding and found a dry joint on the ecu.  Mechanic reckoned it had been running rich for ages and needed a run out. drove it home and it did seem nippier and to run smoother than before. Parked it up (a week ago - its a motorhome) went to start it today;  It started and ticked over lovely, no spluttering or change in tickover.
• Peugeot 407 (2004 - ) - 05 2.0HDi depollution/additive system fault 4 Feb 2016 (Forum)
  After scanning with OBD2 scanner the following faults codes been found P1435 ? Additive system fault (unfortunately I can?t scan additive ECU) P0461 - Fuel Level Sensor Performance P2408 - Fuel Cap Sensor After cleaning fault codes P1435 only comes on after engine start, but after few more starts and other two comes again. I did research and it is linked to additive system.
• Ford Focus II (2004 - 2007) - 05 1.6 Instrument cluster fault symptoms 10 Jan 2016 (Forum)
  Other forums suggest there is no diagnostic for the cluster anyway. Further suggestions have included the ECU and dodgey electrical connectors or wiring. Apparently the alternator is regulated via some part of the engine control system, so this may not be the root cause. I am reluctant to have to pay £280 speculatively for a replacement alternator with no guarantee this is the real problem only to face further bills for who knows what!
• 2003 Renault Megane 1.4 16V Petrol - Megane II 1.4 16V Idle and starting problem 3 Feb 2015 (Forum)
  I have replaced coils, plugs, TDC sensor, coolant temp sensor and cleaned the electronic throttle body twice and even ran some Cataclean through the fuel but have not managed to resolve the problem. My code scanner has found no codes in the ECU and therefore I have no idea where else to look. My only thought was the throttle body O rings may not be tight enough and there could be an air leak? There are no other air hoses that would cause this issue and there is no idle control valve on the throttle body as it's electric.
• Fiat Panda 1.1 Active 2006 - Cold Start problem with idle RECTIFIED 5 Jun 2014 (Forum)
    The fix appeared to be something with the battery !!! There was enough charge for the cranking of the engine but not enough juice to power ECU whatchermecallits........ Anyway, I took battery off (original since new) and recharged overnight. Replaced in the morning and car started perfectly   :) This is clearly a battery issue although just doesnt seem right that battery can start car but affect other crucial parts - which is why I didn't even suspect it in the first place.
• nissan almera - diagnostic tests 27 Dec 2013 (Forum)
    i returned to the garage and again they tested and got the same result, the technician suspected an ecu fault, i sent it off to be tested where it was found to be faulty and was rebuilt for me. (It was diagnosed as something to do with ignition coil).  On putting it back on the car as soon as car was started the needle started bouncing again and the car felt as though it was still struggling struggling for fuel.
• Ford Focus 1.6TDI Zetec - 2005 - Discovered DPF Has Been Removed! 28 Nov 2013 (Forum)
    Upon learning that the DPF has been cut out, and the fact it can ping on only at 70mph (when the DPF would usually regen?), would you guys think that the ECU hasn't been remapped properly when the work was done?   Seems to me that the EML is being pinged because it's forcing the DPF regen, when there isn''t a DPF there?   I'm not overly technically minded, so please forgive any ignorance with the above - any help would be massively, massively appreciated as the car goes in tomorrow for a new clutch (ouch!)
• Vauxhall Vectra B facelift (1999 - 2002) - 00 2.0 16v Stalling - cutting out 23 Nov 2013 (Forum)
  . - When this problem first appeared I took the car to a garage who ran diagnostic test by plugging into the ECU, and they found no fault. - I've checked hoses and breather tubes - no leaks observed currently. Could this be anything to do with a Mass Airflow Sensor ? I welcome any suggestions to get to the bottom of this problem.
• Volkswagen Caddy Maxi 2.0 tdi bmm engine code. - 2.0 tdi bmm engine broken crankshaft. 21 Aug 2013 (Forum)
  Would it work if we tried to pipe these to make fit are or we just going to hit block Wall regards to ecu etc etc. I am told that the bottom half is the Same on both but this is also not 100 And if I take apart a good engine and does not Match can't send back. What should I do any advise would be great.
• VW - Intermittent Throttle problem - Main Dealer Servic 12 Jun 2013 (Forum)
  Some days it didn't happen and others it happened lots. It would clear if you let the pedal off and pushed it down again as you were driving along. No ECU lights came on when it happened. No other problems with tick-over, etc. Anyway after trawling the internet and changing pedal and coils, I saw one obscure post about a similar problem on another make suggesting that a brake pedal switch could cause a problem.
• Ford C-MAX 1600 TDCi - Ford 1600 TDCi diesel performance issue 6 Apr 2013 (Forum)
      The 2 main dealer finds no fault code & have updated the ECU software coding to the latest version but this has not resolved the above. (it did resolve another issue)     I note the following engine characteristic - might this boost be malfunctioning?
• VAUXHALL SIGNUM 2.0 DIESEL 2004 - SIGNUM ELITE POWER LOSS 4 Feb 2013 (Forum)
  I have done lots of research ever since and there are stories of WELL known faults in the VAUXALL and SIGNUM because the ECU, EGR misconfiguration, as well as hose leaks and oil gung. Finally i went to a dealer garage and they quoted me an $$$ and a £££eg for a new diesel pump, which also differs with the other five garage's stories.
