Hi,
Both this and last winter I've had real trouble with the glow plugs on my 2003 ML270. The glow plugs have been changed, and so has the rely. In the summer the car starts perfectly, in the cold it really needs to turn over to generate enough heat and if below zero will not start at all.
Previously people have mentioned it could be fuel starvation but I believe that's not the issue.
What's the best way to both test if the glow plugs are getting power and also are there common places that fail that could be preventing them from heating up?
I've taken it to a few garages, some have said live with it, some have said they can't find a fault. The issue now is when it dropped below zero last month it wouldn't start. It started fine the next day after I opened the hood and let the sun warm it up a while first.
Thanks
Louis
