For some time I was feeling a "clack" noise every time I shut off the engine. I though it was an air bubble on the cooling system, but no.
Today, with the hood opened, I turned off the engine and put my hand on the ICV, and after 3 or 5 seconds, I could feel a bump on the valve, making that sound.
Also, the econometer makes a little movement on its position at about 3 seconds of turning the engine off.
Could it be a bad DME? I have a 318i with M40 engine.
THanks!
