Hi everyone!!

Since last friday, my car has started to develop some kind of strange symptom.
Issue is:

When I start the car after it has been stopped overnight, the engine doesn't fully go to the 750-800 rpm idle speed.
Engine starts, but it stays at around 500 rpm. When that happens, everything seems dead. i can press the throttle pedal fully, move the gearbox leveller, but nothing happens. The car just seems to be semi-dead. Engine just sits there working like a generator, just going vum vum vum vum vum almost chocking...

If i restart the engine, then everything clears out and the car is back to normal.

Anyone has any idea on what I may be facing?

Suggest you say what engine and year of car for people to advise you. BMW i3 Electric Car
2012 Full Fat RR 4.4 TDV8 (now gone)
2006 VW Touareg 3.0 TDi V6

Yeah..

2007 3.6 tdv8

First thing to do is try a battery reset....  Pete

That's one of the last things I want to do... as the car is with the steering lock problem active...
If I disconnect the battery, I'll have to be once again pour 3 litres of wd40 in the steering column to make it work. Always knowing that there's one day that, that solution won't work!

Could that not be causing the issue?.
