Citan Coolant Level Problem
Summary of the thread
A 2022 Mercedes Citan with a gasoline engine experienced a low coolant level issue, triggering the check engine light. The initial suspicion was a faulty cable or plug connection. Suggestions included checking the coolant reservoir cap for a proper seal and considering air pockets in the system. Ultimately, a corroded plug was identified and replaced by a workshop, resolving the issue after a pressure test.

Good shout on the reservoir cap It feels snug, but I'll double-check How would I know about those air pockets you mentioned Any tricks to burp them out Overheating hasn't been an issue, cooling fan seems okay Head gasket failure symptoms are different right

Yeah, head gasket would usually mean other nasties too As for the air pockets, there are ways to bleed the system, but I wouldn't mess with it too much myself If it's still dropping coolant, it's probably best to get it to a workshop They'll have the right tools to diagnose it properly and pressure test the system

I appreciate the insight I took it in, and you were spot on about a dodgy connection They replaced a corroded plug, pressure tested the system, and it's all good now The bill came to 95€ It saved me a ton of stress trying to troubleshoot it myself

I had something similar on my Citan Check the coolant reservoir cap first, make sure it's sealing properly Air pockets can cause coolant loss too Is the cooling fan kicking in like it should No signs of engine overheating, right
