Engine hickup on startup

Josparky · 09-15-2018, 06:27 AM

Hi Guys

Trying to find out an issue i have been having on and off.
Anyone has had similar issues pls let me know...this only happens on hot days.

2011 E92 M3
Mileage: 40k

Drive car for about an hour.
Park car
Come back after about 30mins
Start car and engine starts fine then rpm drops below 500 up to 700 then drops down to about 200 then continuos rough idle then engine light comes on.

Turn off car.
Wait 10 secs.
Switch back on and it’s fine...
It seems like heat soak is causing this if the engine gets very hot whilst car is switched off...

Anyone had similar issues?
