Overall, a mega maintenance weekend with an extensive replacement set:
Engine oil & filter
Transmission oil (Pentosin MTF2)
Differential oil (Castrol SAF-XJ)
Valve adjustment
Air filter
Cabin filter
Other inspection II 'inspections'
Engine coolant
Vanos filter & 'o' rings
Spark plugs
Alternator & air conditioning belts
Engine mount bolts torque check
Front & rear brake rotors & pads
Parking brake springs
Stainless steel brake lines & brake bleed with ATE typ 200
CDV delete & clutch bleed
The car now feels stronger and smoother than ever before!

That is quite a few tight exhaust valves, valve stretch or seat recession I guess.
