W212 E250 CDI (OM651) - changed the inlet manfold after getting a boost leak and swirl flap return position errror. Also found a bolt missing from the EGR and a substantial leak that had been driven with undetected for a while.
Finally all back together and running but I now have a P0101 code (displayed as P0101 62 on my health report). I have tried to clear it but it comes back instantly. Yes it could be a leak in my inlet system or EGR but it comes back straight away and I can't hear any whistling. Engine off I get a reading of 0.16g/s, idle that rises to around 100g/s at the 3k limp mode rev limit.
I have also put a brand new Mahle air filter in. I have checked the pressure sensor immediately after the MAF - all looks clear. There is a sensor on the elbow down after the throttle body - which is pressure I think? I did visually check it was clear but could try and fish it out and recheck but googling would suggest 50% of advice is that the car needs driving or an ODB/star triggered relearn. Got it's MOT tomorrow so first time I can drive it on the road is on the way with fingers crossed. I have spoken to my local specialist who is skeptical it needs a relearn after an inlet manifold so I am planning to drive the car straight to them after the MOT for diagnosis (on the way home).
I have a Launch 429C which doesnt seem to have a relearn function. it does have a throttle relearn but I am not sure that will work while a DTC is active. I saw some people say their cheap readers had a relearn function and I do have a cheap Vgate BT reader that I previously linked to Torque so wondered if anyone knew of an app that had the relearn or are they all pretty much read data/codes only?
Any other ideas?
Oh and I did re-use my swirl flap actuator so that shouldnt need coding in.
