• Honda Jazz 2016 - Starting problem - Battery / charging system 30 Mar 2018 (Forum)
  and asked them to do a test on the battery but was told that I need to book in next month as they are too busy. 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
• Jaguar X-Type Estate (2004 - 2007) - 04 2.0D Engine cuts out..... 20 Oct 2017 (Forum)
  on to the main injection pump and it still would not start. 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

  problems, it runs perfect. The engine sounds good. 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

  the speed. 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

  .    Started it up and it started and ticked over, as soon as I put pressure on the throttle it cut out. 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

  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

  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.

• Ford Focus 1.6TDI Zetec - 2005 - Discovered DPF Has Been Removed! 28 Nov 2013 (Forum)
  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

  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. {edited

  , the rail is primed and there is loads of fuel pressure so didn't appear to be a fuel supply issue Took it to a garage, had diagnostics done, ecu reported a faulty crank shaft sensor, replaced this, made no difference (although it has cured the rough idle when it is running) Battery is good, in fact

• All - DPF regen and low EGTs 2 Jan 2012 (Forum)
  with the low engine load. With low EGTs, the ECU has to spray disel into the exhaust gas stream to raise the EGTs to a sufficiently hightemperature to burn off the soot. Clearly this is waste of fuel since diesel burned in the exhaust does not contribute to useful work. But the more worrying problem
