Fredde Posted April 9, 2016 Share Posted April 9, 2016 just got my self a Ford Transit Connect -08 1,8 tdci. One morning it didnt start and the immobiliser flashes error code 23. After googling I got "23 - ECU ID mismatch (duff ECU)" I have had a company to rematch my key with the ECU, the programing worked and the key info was saved. But the error code remained and the car didnt start. Can I fix this problem using a other ECU and its matchning key from another Transit Connect of right year? Can anyone confirm what the error code means? Quote Link to comment Share on other sites More sharing options...
mrtn Posted April 9, 2016 Share Posted April 9, 2016 Doesn't it start anymore at all? You may have a broken reader coil around the key barrel. Mine flashes some code every once in a while (worn key/barrel) but always starts at the next try. Quote Link to comment Share on other sites More sharing options...

103west43rd Posted April 10, 2016 Share Posted April 10, 2016 Hello Fredde, try the UK Transit Connect forum, http://fordtransit.org/forum/viewforum.php?f=54, since you have a diesel (no diesel's here in the US) there may be something specific to the diesel. Good Luck. Quote Link to comment Share on other sites More sharing options...
103west43rd Posted April 10, 2016 Share Posted April 10, 2016 Fredde, I noticed you tried the UK site but got no replies. Thanks G B L and mrtn for responding. Maybe the UK forum will come up with something. Quote Link to comment Share on other sites More sharing options...
mrtn Posted April 10, 2016 Share Posted April 10, 2016 The UK forum has gotten considerably quieter lately as most interaction is taking place in facebook. Looks like the error code is Ford-wide. Another model solution should work in your case as well. Quote Link to comment Share on other sites More sharing options...
G B L Posted April 10, 2016 Share Posted April 10, 2016 There are several ways shown on U-tube to buy pass the Immobilizer, Several from the EU and applying to the Diesel Transits. If you put Ford Immobilizer Problem lots of info appears. Quote Link to comment Share on other sites More sharing options...
