Mercedes A Klasse Stalling at Idle Resolved

My 2003 Mercedes A Klasse gasoline, with 261860 km, has the check engine light on, stalls at idle, and has reduced power. I suspect the fuel pressure regulator after a fuel filter change. Any ideas?

Summary of the thread

A 2003 Mercedes A Klasse was experiencing stalling at idle, reduced power, and a check engine light. The initial suspicion was a faulty fuel pressure regulator, especially after a recent fuel filter change. After confirming the issue, replacing the fuel pressure regulator resolved the problem.

I had similar issues on my A Klasse: check engine light, rough idle. Did you inspect the fuel rail pressure after the filter change? Could be air in the fuel system. Also, when was the fuel pump last checked?

Fuel pump seems okay. How did you resolve your fuel rail issue? Was it the regulator itself?

Yes, it was the fuel pressure regulator. The car ran poorly until I replaced it. Given the error entry after the filter change, and your symptoms, I'd advise getting it checked professionally.

Thanks. It was indeed the fuel pressure regulator. Replaced it for 45€ and the problem is solved.
