renault scenic 1.9dci rough idle - zephyr6boy
hi, i am new to diesels. other cars '66 Zephyr and 2.8 Capri. The scenic drives great and smoke free but it has a rough /lumpy idle. i put some millers diesel + in and it cured it for a while. Blocked injectors or time for a glow plug change???
Any ideas appreciated. Cheers.

Could be the EGR valve getting a bit gummed up. You could just take it for a hard drive to clear out the cobwebs.

Exhause Gas Recirculation. They get a bit gummed up especially if the car's used mainly for town driving. Often an Italian Tune will help, otherwise take the valve out and clean it. Fit a new sealing ring though.

SFAIK glow plugs are only for starting the engine and can have no effect on how it runs after this. Changing glow plugs is not going to help a lumpy idle.
