| | Phil This engine uses Piezo Crystal type fuel injectors. The fault code P2146 can indicate a problem with one of the injectors going short circuit to earth internally. If you remove the engine cam cover and check the resistance of all the injectors between the two electrical pins, then check each pin for resistance to earth, you may find one of them has a problem.

| | Hi Andymac That sounds familiar, we had one a few months ago, replaced 1 injector, all good. Car came back a week later on towtruck, needed another, which was replaced, but we didnt even make it to road test before the third one went down. Luckily for customer the fourth one hasnt gone yet !!!! Still waiting though.
 I would rather be sailing |

| Yes, the moral is replace all four but if the owner is a taxi driver with limited English you try explaining that one…

| Breath man breath, you have gone purple! Yes, you know exactly what I mean. I had a chap in just before lunch, cam gone on his 150PD, I said it will cost about £1300 which did not seem to register and his reply was “can’t you just fix it?”, like what I was saying wasn’t to fix it!
