hi everyone
Has been some time since my last post. Hope you are having a nice ride with your mercs.
I am having a tiny issue with my w211 220 cdi MY05. For two weeks now when i start the engine and it is cold the RPM are fine and the idle is smooth. When it gets to operating temp. the RPM vary and idle it`s not smooth at all and goes up and down a bit and it`s very irritating. Have read some threads that say it can be the fuel pressure regulator. Is this the issue? What else can make the idle unstable when engine gets at operating temp.?
Any idea is highly appreciated.:smile
