Could you elaborate on the specific aspects of the fuel injection system you inspected Were there any particular diagnostic codes that pointed you towards the injector issue, or did you rely on physical inspection and component testing

I didn't get too deep into it myself The symptoms were similar, and based on past experiences with other vehicles, I suspected the fuel injection I took it to a workshop and they confirmed it Saved me a lot of hassle

I had similar symptoms on my B Klasse Check the fuel injection system thoroughly It could be a faulty injector causing the rich mixture
