• Seat Altea 1.6 - Security Code Engine ECU 20 Oct 2014 (Forum)
  Any way the dealer said it needed a new dash control panel which i agreed to , but they cannot code this to the engine ecu . Now after weeks in the garage  its been decided that the security code has been removed from my engine ECU , the garage are waiting on further advice from Seat Technical , but i spoke to the garage technician who says he can put the car back to the way it was with the original control panel but i wont have a spare key and goodness only knows what they'll charge me as my quote was to replace the control panel .

• Chrysler Grand Voyager 3.3 LX - Voyager 3.3LX starting problem, no spark at plug 4 Nov 2011 (Forum)
    The crank case sensor, plugs and leads have all been changed and had no effect.  Last week an auto electrician examined the car and said he thought it was the ECU, only problem is that the ECU is part no. PO4727158AJ and I am told that this particular ECU cannot be test.  Although I have sourced an exact replacement part no. I am told that Chrysler can charge £1000 to reprogramme one of these (I'm waiting for a call from Chrysler to confirm this).

• Golf 1.6 16v Performance probs... 24 Jan 2003 (Forum)
  Curiously, the warmer the engine when the car is started, the worse the problem is but performance never deteriorates if the car was started from cold! It's as if the ECU makes some kind of decision on how to setup the engine when the car is first started. The car is an import so is now out of warranty but three ECU,s, two EGR valves and several other sensors later and nothing changed.

• SEAT Ibiza III - Seat ibiza 1.2 tdi CFWA 31 Mar 2018 (Forum)
  The codes are not really important here as it was a short cicuit.  Anyway after searching for a whole day I found the issue right by the ecu just as I was about to take the ecu out to test.  It was on the main loom under the ecu and had rubbed on the metal bracket. Hopefully could save someone some time. Included pictures of the fault.
• Vauxhall Astra Twintop 1.9 150 Design - Spanner warning Light 23 Sep 2011 (Forum)
  Long story but I've been back and forth to Thorney Motorsport, they have carried out diagnostics, regenerated the PDF, changed a PDF sensor and updated the ECU. As far as they are concerned all seems to be working OK but I still have the spanner light on. The garage passed all their findings on to VX technical and the response was, 'It MAY be the ECU'.
