• Fiat Panda Multijet 2006 - Suitable fault code reader 3 Jan 2013 (Forum)
  that the cheaper a OBD reader is, the less it can do, but can I get something that will identify why an engine fault light has come on so I can at least have an idea of which sensor is sending the ecu an unexpected reading? I don't like the idea of having to take it to a garage every time anything whatsoever goes

• 1995 toyota celica convertible 2.0GT Auto - Celica Charge and Catalyst lights suddenly on 12 Jul 2012 (Forum)
  . There is the charge (battery symbol) and also "toaster" style symbol (catalyst ??) both on at once. Tried disconnecting/reconnecting the battery to clear ECU but they remain. Tried disconnecting battery with engine running and it dies - does this mean the alternator is dead ? Why would that cause the catalyst light
• Citroen Saxo 1.1 starting problems 30 Apr 2012 (Forum)
  lit. Does the latter mean that fault codes have not been recorded by the ECU? 2. We have got a Haynes manual and can see that several sensors and actuators are involved in starting the engine. Anything got any suggestions about this particular fault.
• BMW E46 320D - Ignition/Starting Issue 6 Feb 2012 (Forum)
  not inclined to spend £170 or so on a pump just yet as people who have gone this route seem to continue to have problems and I get the feeling its more of an electrical issue i.e. signal to/from ecu or instrument pack etc. Has anyone found the root cause of this issue? Thanks
• Peugeot 306 - 306 rotates but wont start 7 Aug 2011 (Forum)
  called the RAC out and they couldnt find the problem but suggested i change the relay behind the ECU, which i did but the problem still persisted, i took it to the garage to be plugged into the machine and they said there were no faults and it was probably because it had been stood and needed to be run

  ), I have had the fuel filter changed, I have had the earths checked, I have had the breather from the fuel tank checked, I have had the MAF sensor replaced, I have had the ECU removed and tested twice with no faults showing.

• Astra 1997 GSi 16v 2.0 - Loss of power, and sudden jerking 24 Jun 2011 (Forum)
  any hesitation and it sounds perfect. To exclude the EGR, I blocked it off, and it is exactly the same symptoms, and no engine light, or error codes from the ECU. Thanks, Ryan.  
• Toyota RAV-4 (1994 - 2000) - 1996 2.0 Immobiliser problem 22 Apr 2011 (Forum)
  ) My options are ( if i can somehow get car towed or transported over there) 1: Have "zapper" unit re-programmed, if still dead, 2: Have ECU in car re-programmed. 3: If above fails, have all wiring associated with immobiliser removed, but noted that they do not have wiring diagrams, so would have
• Ford Focus II (2004 - 2007) - 2003 1.6 Live Data Expert? - Idle Problem 3 Feb 2011 (Forum)
  updated my ECU software?? Cleaned the idle control valve The problem is this when I stop at lights/junctions the engine vibrates, sometimes the whole car. It gets worse at night when lights are on etc and you can tell due to, flickering lights inside and out, when you have the rear heated window on, even

  drive by wire jobbie, Z18XE engine code I think, Simtec 71? ECU, certainly it needs a proper ODB code reader rather than my trusty paper clip :-((
• Hyundai Getz - Any Engine management experts out there? 15 Dec 2010 (Forum)
  air 22C. It would appear the temp sensors are ok but the lambda reads low when cold. Apparently the ECU's run open loop when cold so in theory the lambda sensor is ignored. Anyone got any ideas please?

  a workshop manual 2) what is the next step up the electrical line on this model 3) Could I have nudged an emergency/accident cut off/immobiliser if there is one fitted (& where would the reset be?) and 4) Does this car have a CDI/ECU and where would be the best place to get one?  Many many
• Toyota Celica (2000 - 2007) - 03 1.8 Engine management light and VVT controller 19 Jun 2010 (Forum)
  be affected is the fuel consumption which seems lower. I'm getting about 30mpg now. I've taken the car to two Toyota dealers who both retrieved a P code from the ECU that indicate a POSSIBLE problem with the VVT controller. They costed it around £500+ to replace this unit. They seemed reluctant to give me

  on the market as well although I'm not bothered about upping the size for any reason but availability. I think the last engine swaps I did ,apart from the Jowett, were an old Mk 1 Kadette and a couple of Ladas. No ECUs or anything there !......Points is points ! Thanks. Ted
• Ford Galaxy (1995 - 2006) - 02 2.3 Mis Fire - At my wits end 4 Feb 2010 (Forum)
  . Mechanic is scratching his head and reckons there is only so much he can do. Has suggested getting a check done on the ECU to see if that is on its way out as a last option but he isnt overly optimistic. Would that be a good idea? What else can i do to fix it as i am getting more worried about my wife
• I have an idea 12 Jan 2010 (Forum)
  that, why not combine with electronic throttle mapping so i can have a nice fast sports car, with say 300+ BHP, but when may daughter gets in, touches the keypad, BHP is limited to 90 or so, and the throttle response matched to a Nissan Micra. What a cool idea? So much can be done with ECUs, "sports

  loss in the PS and possible software changes in the ECU. I recently had the cambelt changed in the newer one (at 70k and 12 years) (no lectures please), and believe it or not this car now feels much better - almost the same as the other one! The only conclusion I can come to is that the original
