Yes changed full kit only thing not changed is inlet vanos Timed up by pin crank locked the vanos's then fit the cradle and set tension on chain with tensioner replacement. Changed the 2 seals on no 1 cap with BMW fibre / rubber replacements and soaked in oil before fitting.
Reset the adaptions with the autel, the readings were perfect middle of tolerance when adapted. I'm inclined to think oil pressure but if you start it and hold the revs it still does it.
I wondered if there was a software update that had a bit more tolerance.
i do believe there is a update for that remember someone else on here had same issues they said took it to mini mini downloaded a software update,,
after you reset adaptions did you start car leave on idle until up running temperature ie fans come on then go take it for a good drive,, i do that on the peugeots alot and they play up a bit in the beginning i start first part of drive to 3k then build up to rev line over a few miles it helps the ecu to relearn slowly so dont get confused if that makes sense.. but before any of that need to know what oil pressure is doing..
another thing i have found try locking the car off again with the tensioner in and not the pre;load tool, i have found just a tiny bit to much preload bends the chain guides and makes car run retarded,, i have stopped using a preset torque on preloads now i now do it by eye and feel and when its correct i can lock cams and crank off with chain tensioner in place,, honestly try it,, its so weak and flexible that dont take much force from preload tool to throw it all out,, i done a 207gti 175 the other day or should say redid it as another mechanic had a go at it and did not go to plan,, i tend to get these now as just done enough of them and get them right 9 times from 10 the first time now, but in the beginning had a few failures where not until road test you find timing out,, proper rubbish is what it is
