Hellow all,

I have recently developed a strange problem with the glow plug light on my 1997 E300.
After I start the engine the glow plug light sometimes comes back on and stays on for a minute or so and then goes off. The engine starts fine, but once in a while in extreme weather it will sputter at idle. Any chance this can be caused by a faulty glow plug relay? Where is the glow plug relay on the W210 (1997 E300)?
I really hope this its not a sign of bad glow plugs. Again the key thing to note is that the glow light will go off after a minuite or so.

Any ideas would be greatly appreciated.

Thank you,

Alex
