Peugeot Expert Check Engine Light

My 2006 Peugeot Expert (gasoline engine) is giving me grief. The check engine light keeps popping up. I'm guessing it's something with the air supply. I've checked a few hoses, but I suspect the connection from the pump to the valve might be defective. Any ideas?

I had a similar issue with my Peugeot Expert. Check the throttle body for vacuum leaks, that's usually the culprit. Could also be an air intake issue somewhere.

Thanks! Where exactly should I be looking on the throttle body? Any specific hoses or connections that are known to cause trouble?

Honestly, it's hard to say exactly without seeing it. The hoses get brittle over time. I'd give them all a good wiggle and see if anything changes. If you're not comfortable, a workshop will sort it quickly.

Cheers! I appreciate the input. Turns out it was a cracked hose just like you said! Cost me 175€ to get it sorted.
