Mercedes V Klasse Diesel Fuel Filter Heater Issue

That sounds familiar I had a similar issue with my V Klasse Loss of power and rough idle suggests fuel starvation Have you checked the fuel filter A faulty fuel filter can cause similar symptoms It's like a clogged artery in your car's fuel system

Thanks for the quick reply I haven't checked the filter itself yet Do you recall any specific error codes or details from when you had the issue Was it definitely the filter or could it have been the heater circuit as the error code suggests

I'm not sure about the exact error code but the symptoms were almost identical Considering the error code points to the heater circuit a defective cable or plug connection is probable A workshop visit is advisable

Appreciate the advice It was a faulty connection to the fuel filter heater just like the error code suggested They replaced the connector and it cost me 95€ It runs great now I'll keep an eye on the fuel filter and probably schedule a filter replacement soon
