E220 cdi 2002 Poor Starting especially when hot. - TRracer
Recently purchased a 220cdi estate my wife to use , It has been good with excellent fuel economy but cranks forever before it starts especially when hot. It broke down this week and as my wife is a nurse needs to be reliable. I have since purchased and fitted four new glow plugs but the old ones looked like new when removed. I also recollect finding a can of Bradex easy start under the seat after purchasing the car !!
Any ideas would be appreciated as my wife is panicking and wants her old car back!!

Similar symptoms on BIL's E46 BMW 330d couple of weeks ago. Burnt out heater relay - £28.36 plus labour.

HI I presume this is a relay which feeds the glowplugs when starting as i can check the voltage at the plugs . Thanks for any help Steve

The O-ring under the fuel rail pressure regulator has likely split, or one or more injectors have cracked and are releasing the fuel pressure when cranking.

If you bought it from a dealer - take it back. It's pretty clear why it was sold. It really needs a Merc specialist to check the injector numbers too; they have issues.

Hi thanks for your reply - the vehicle was a private purchase via autotrader. However your hints give me lots to check out myself before i have to try a main dealer.
I must say a friend told me about this website on Saturday and I think it is brilliant ..Thanks again for your help Steve

If you're thinking of having a go yourself, get a manual and read-up on the safety precautions of working on something with 20,000 lbf/sq/in [1350 bar] inside it.

I wouldn't try and remove any glowplugs - they break off and that's £1500 gone to get the bit out. If it won't start hot, then the plugs don't come on then anyway.
