Mercedes V Klasse Diesel Engine Stalling

My 2018 Mercedes V Klasse diesel is acting up The check engine light is on and the engine sometimes stalls at idle I think it might be the tank ventilation valve, maybe in the EVAP system My mechanic said it could be clogged hoses affecting the pressure sensor Has anyone else had this happen The car only has 11834 km on it

A 2018 Mercedes V Klasse diesel was experiencing engine stalling at idle and a check engine light. The initial suspicion was a problem with the tank ventilation valve, possibly within the EVAP system. A mechanic suggested clogged hoses affecting the pressure sensor as a potential cause. After inspection, it was confirmed that partially clogged hoses were indeed the issue, and cleaning them resolved the problem, turning off the check engine light.

Did this summary help you solve your problem?

Sounds like an EVAP system issue I had similar check engine symptoms with my V Klasse Have you checked for any obvious cracks or disconnections in the hoses connected to the tank ventilation valve A leak there could mess with the pressure sensor readings and cause the stalling

Thanks I looked at the hoses but didn't see anything obvious You mentioned a leak affecting the pressure sensor readings Can you say more about what those readings should be normally, and how a visual check might miss something subtle

Getting into exact pressure sensor readings is technical without the right tools If you didn't see anything obvious like a split hose, it might be a partial blockage or a faulty valve I'd recommend a workshop check They can properly diagnose the EVAP system

Thanks for the advice I took it to a mechanic, and you were right Some hoses were partially clogged, messing with the pressure The tank ventilation valve was working The repair cost 175€ to clean everything The check engine light is off now
