Car Forum / Mercedes-Benz Cars / August 2007CDI starting
Hi, I noticed I can easily start my E 220 CDI (W210) without preheating although instructions recommend to preheat. Is it ok to do so or do I risk damage in some motor part? Thanks! Kind regards robert >Hi, > [quoted text clipped - 5 lines] > > robert I never saw anything about preheating, no do I ever preheat, never had a problem starting up, I have a w211 e320 Glow plugs are there to provide easy starts AND less smoke upon start up. Your car's motor may seem to start with out waiting for the glow plugs' cycle to complete but the glow plugs are heating anyway. In fact the new motors continue the "glowing" for an additional minute or so after the motor is running to reduce emissions.  Signature© 2007 T.G.Lambach.

Even if the GP's are heating they might do so for a shorter period of time if the engine is also running (I guess they are temperature controlled). Thank you for clearing this up! Kind regards robert PS: the manual then is probably a bit dated. :-) I just had a (Fiat) td on hire for a fortnight. I kept forgetting to look at the pre-heat light and started like in a petrol-engined vehicle. Only had a hiccup once because I turned the key further immediately immediately, as opposed to just 1 - 2 s immediately. Complete difference to my old regular non-turbo (Merc) diesel of 25 years ago...
