Hello guys! I got my dad’s clk for a month now and whenever i start my car cold the rpm stays low as if the car was warmed up already even after 2 days of sitting. Also sometimes the rpm needle will go up 2k rpm and then go down again many times for the first 3 minutes then goes back to normal. Why could it be?

you have issues with the ECU and the emissions system----get a scan for details and faults

Alright, what cheap obd scanner would suggest me buying ? so I can scan fault codes myself because I have a w211 myself as well

I picked up a Bosch 1150 for $55 and use it on my CLK430 2003. Works great and I love the graphing and record features for diagnostics.
