Sounds like a Little leak in the fuel pressure System
Check the fuel Lines and tubes

 

Thanks will have a look

 

does it smoke heavily when it starts?

 

Yes it does smoke I thought this might be the fuel that had built up whilst it ws trying to start. It runs clean after the intial belt of smoke.

 

I have the same problem, I think it's a glowplug problem on mine, but I haven't had the time to look...

 

Thanks for the imfo I was thinking like that but expected to get some form of error code. My dealer is about 100 miles away so I was trying to get as much info as possible before driving over there just for him to tell me he cant find anything wrong unless I leave the Jeep with him, and then he can start to build up his holiday fund for next year.

 

You have an OBD2 code reader?

 

Not at this moment but I will have very shortly. Have not picked out what to buy yet but am reviewing post in the forums. Thanks

 

oh, ok because not all codes throw CEL

 

read my codes today, no CEL but gives glow plug modul fault.

If it was fuel pressure related it would also do it when warm.

 

Recived my code reader today and shows simmilar U0106 (lost comunication with glow plug modual)
So now will visit dealer and see what the fix is going to cost me. This will test my 2 year waranty.

 

OK fixed I hope, started OK this morning

One Glow plug number 6 Mercedes part number CK 68102087AA 32.30 Euros
Glow plug control modual Mercedes part number MA 642 900 28 00 145.28 Euros

Dont know how the parts prices compare to US or rest of world, I am in Spain
Two hours of dealer time including 20 minutes diagnostic time.

Thanks for all the imput

 

I have a 2008.5 CRD. And it gets pretty damn cold in Calgary. About the same temperature as you state. the manual says you should plug it in (block heater) whenever is gets below freezing... I do that and have had no issues like you are mentioning. I turn the key to on, watch the glow plug icon light and when it extiguishes, I start her up. The only times (x3) it has ever taken more than a few seconds to start, it threw a code... and the engine was hot.

 

I have never plugged my 08.5 in. I am trying to see just how cold it can get for starting issues. So far here in Ontario Canada the coldest day which was around -45 with windchill it started just fine, now my transport it had a problem starting that day.
