Glow Plug Lamp
Hi Folks,
I've been through the archives but can't find an answer. Our tintop is a Renault Scenic with a 1.9TDi engine. It starts and runs fine.
However after around 20 mins the glow plug lamp comes on. It stays on for around 5 minutes or so then goes off. This happens randomly through a
journey and does not seem to affect the car. We have a 4.5 hour journey to Sheffield this week so I'm keen to find out if I should be worried
about anything. I put it down to the very cold weather.
Has anyone had this problem or can they shed some light on it?
Thanks in advance,
Donny.

The glow plug lamp on these doubles as a Malfunction Indicator Light (MIL). It should have a fault code recorded.

Hi Mike,
thanks. Long story short - the battery was flat / gubbed and this was low battery voltage indicator. New battery from the helpful Tony at qwiklube
in Edinburgh (friend's recommendation) fixed it. They also hooked up a diagnostic tool to confirm and reset the fault codes.

Glow Plug Lamp - Update
Hi all,
just a quick update. It was not only the battery that was causing this lamp to come on. Apparently there is a known issue with the exhaust gas
recycle (EGR) valve. Mine was sticking and eventually failed. ALso, the disk in the valve which regulates flow is only a push fit. When this works
loose, the valve passes. This will end up being so bad that the exhaust gases poison the engine and it will not run.
There is a temporary fix (should the AA have known this?). The valve can be rotated 180 degrees and used as a blank to block the flow - to get the
car running again. This is not a cheap part. The new valve has a modified connection to the disk so this should not happen again.
Cheers,
Donny
