Hi got this one at the moment & Autologic’s Tech is off with serious man flu, with my own knowledge of this problem I am unable to advance this problem. The vehicle drives & when accelerating the engine jolts you with momentary cutting out during acceleration.

The codes in the system are D228 [intermittent] Brake information: Coherence with redundant brakes??? & D026 [intermittent] Cylinder 1 injector control circuit: Short circuit to +12v??? The second code being the more relevant. Or is there a CAN fault cutting the engine thinking the brakes are being applied, that's a very strange code combined with the injector code, in the engine management system?

I’ve been sent a raft of information on checking the D026 code and injector testing the resistance. I assume the injector is buried deep in the cam box somewhere and is this the likely cause? There is no misfire, just momentary cutting out under acceleration. I assume there could be oil contamination up the loom? Has anyone had an injector out on one of these later Renault engines, and what sort of job is it to do? I would appreciate any help from some one more experienced than myself.
