ML270 CDI glow plug lamp coming on

[Staffs ML270 CDI]

Help!!

My ML270 CDI 2002 has a problem, first start in the morning ignition on, glow plug light goes off, I start engine and after a few seconds light come on again and stays on for a minuite or so, then goes off and stays off........

Any suggestions?

Cheers all

Hello

Probably a faulty glow-plug. If the ML systems works like the C system then the cycle goes something like this:

Ignition on starts pre-heat
Light goes off to signal end of pre-heat
Start engine
Glow-plug control module initiates after-heat (to improve post start running) for up to three minutes
Glow-plug control signals faulty plug by keeping light on during after-heat

You can confirm by checking wth a basic multi-meter.

(I've only ever sat in an ML once, but this sounds so like the other glow-plug problems that ever read about that I'm venturing a guess!)

David,

Many thanks for your reply, I will organise to get the car in and get the glow plugs checked out. she done 70,000 so maybe its worth having the lot done................lets see what the cost is first O)

Precisely the same symptons that my ML displayed...........It was one of the glowplugs that had failed, i renewed all of them and have kept the old 'good' ones as spares.

From memory....they are about £12 each from MB and easy to renew.

Stockists for Beru Glow plugs

The GSF branches are found here - http://www.gsfcarparts.com/contact/branches.asp

Mercedes spares price for these same parts (with the MB logo and additional part number on them) is £13.77 +VAT. Roughly double the OEM part cost.
You may find it easier to source these locally once you know exactly what you require which is Beru GN003 type.

I have also posted a reply with useful links on the other thread by the way
Best of luck anyway, it's no harder than changing spark plugs I found.
