HI there

I've got a Peugeot 206 hdi 2.0 litre on a 55 plate, engine management light came on the other day read a p0401 code. Garage says it's probably the egr valve. Only thing is my car runs perfect idling acceleration etc. Could it be something else. I've read other posts and they have had driving issues. I definitely dont want to blank it but if I could clean some gunk out of the valve would that work. Many thanks in advance.

Best wishes

You could try using a can of Wynns egr cleaner on it. Be prepared for iit to sound like every bolt has come loose and is rattling around inside while using this stuf though. It's not as good as stripping it down and manually cleaning but it made a huge difference to my 2.0l 307 HDi.

The information I have for that code is : Exhaust Gas Recirculation Flow Insufficient Detected. You have nothing to lose by trying the egr cleaner except a few quid but it could make all the difference.
