For what it’s worth, I also had a groan from the steering wheel/column area and feared the worst. Only thing that made it go away was moving the steering wheel down slightly using the adjuster underneath. Something was not happy when it was fully ‘up’.
Thanks Alec for looking. Being a diesel, then I did wonder if the throttle valve always being open (if open means 100%) is totally normal - just can’t shake the feeling that something may be off - especially knowing how most components on the intake system get carboned up.
Morning, had the app running all the way to work this morning - never showed anything other than 100%, regardless off full throttle - 100% right from engine on (cold). Double checked with the obd scanner (TP %) when arrived (so engine hot but idling) that saying the same. So at least this...
Both OBD and the Mercedes Me app showing throttle valve at 100% all the time.
Car drives fine, but rough for ~5 secs just after switch on at idle until given a bit of gas, like it’s struggling to get to 1000rpm.
Didn’t want to link 2 issues that might be unrelated, but wondered...
