Before the end of this year I want to sort out the following problem.
When I start the engine (cold) is running on 6 cilinders (fine) but after several minutes it is running very erratic. One exhaust (driverside) is warming up the other one is cold. No faultcodes on the display and laptop (!?)
What could this be?

Worn spindles
Leads/plugs
Fueling -reset adaptives and throttle position

looks fine, no problems here. Adjusted the valves, new leads, plugs etc. Bought the car as a salvagecar. Now running for the first time after standing still 2 years. Did only 13 000 miles. Ignitioncoil suspect?

The coil normally gives different symptoms, misfire at 3k ish.

Could just be it needs a clean, reset and the tbs balancing.
