    Mercedes Diesel Cold Starting

    I have serched High and Low to get a recomendation on Cold starting the new BlueTec Mecedes Diesels....

    I have found nothing...except they may possibly need a diesel antigel agent???

    Anyone?

    By cold I mean -35 C (- 31 F) without wind chill.

    Does it have a block heater? if so plug it in for 2-3 hours before use a good fuel supplier and maybe some Anti-Gel and you should be fine. If no block heater check with your dealer and see if the offer an OE heater kit. What does the owners manual say?

    Just looking at possibly getting one.

    Mercedes provides a block heater with all its cars up here so no problem...

    The issue arises when I go XC skiing and park the car where there are no plug-ins....and potentially no one to jump it either.

    Merecedes does have a Anti-gel product and that may help...I beleive the winter diesel up here is made so that it does not gel at -35 C.

    Yeah I guess I probably have to read what the owners manual says....and maybe find some people who have tried them out up here.

    if it has been ran during the day you should have enough residual heat for a few hours of sit time . If it sits over night it may be a different story. if you get one try it a few times over night with out plugged in. see how it does

    That is what I am hoping for....the dealer says no problems....

    but I would have to wait until it gets cold to try one out on the lot...

    Just hoping someone else has already been there and done that.

    I am speaking from typical diesel engine experience so that VW should react the same.

    Most diesels will not reliably start if left out at -35 C for 4 plus hours without a block heater.

    the lowest I started my old TDI was -17C (0F)... it took a couple cyclings of the glow plugs to start plus using Anti-gel. I personally used PowerService All-Season Formula (white bottle). The Germans like Stanadyne products.

    the VW community seems to prefer a recirculating coolant heater vs a block heater.
