ABS/ESP

Since car always said ABS and ESP not working and I cleaned the wheel sensors and the steering angle sensor I started looking for something else, this can’t be good:

Need new bracket also:

Bought the whole Traction system hydraulic unit(A7/3), but then did some reading and when system is just woken it is 60 bar of pressure, when working 160 bar, so gave it a shot just swapping the control unit:

They are “identical” but different part number, mine comes off a E500:

Magically ESP warnings gone, ABS warnings gone, Adaptive steering is back in working order and Cruise control started working. Case closed.

Rough running

Engine is running kind of rough, especially when idling and can stutter from time to time, but never with a heavy foot on the pedal. Saw that I forgot to connect the airpump to the airbox, gave me the idea to look for other hoses that might be loose.

Off with the airbox, saw the conntector to the LMM was a little bit strange, and yes, LMM has been replaced, it has junkyard writings:

Then noticed this:

Since when is it ok to repair large wholes with tape? Also a lot of cracks and not fitting well, loose:

Ordered a new one:

In place:

LMM back:

Check engine light gone, still a little rough, pulled code and got misfire on Cyl 5, changed ignition coils between cyl 5 and 6 to see if error moved. But unfortunately no more errors and still running same, might need to drive more.
