Peugeot 406 1900 TD - Pug406
Hello Lads/Lassies

Just bought a Pug 406 1.9TD.
A couple of times the Engine dianogstic light has flashed on for a few seconds then goes out.
The car seems to run fine and it only seems to happen when coasting down hill
I did clean the engine so maybe its water but that was a while ago
Any ideas?
