2001 Beetle TDI - 80k miles
Question for you all. My Beetle is hard to start once the temperature
get down below say 50F. By hard, I have to keep the starter engaged
quite a bit long, probably like 10 seconds. I have a history of
diesel ownership and this is the first one where I don't notice the
glow light on the dash staying on longer when the temperature drops
(which I find odd).
Anyway, my initial thoughts turn to the glow plugs not getting hot
enough. My other thoughts are maybe the starter isn't turning the
engine fast enough to build up compression.
I've tried cycle the start switch three or four times, in an attempt
to heat the glow plugs up more, and then engage the starter, but that
doesn't seem to make much difference. I don't know if the glow plug
dash light is a true indicator of glow heat. The glow light in the
Meredes I used to own would stay on for 15 seconds or better when it
I don't want to burn up the starter and don't know what the duty cycle
of that would be.
The engine has, and always has been serviced with synthetic oil. I
thought that stuff wasn't supposed to thicken up like regular oil when
I guess as a testiment to the battery, it is the original battery.
The battery has given me no problems, but does drag a little when it's
cold. It might be time for a new battery.
My guess are either glow plugs, battery or this new low-sulphur diesel
Finally, I have NO troubles with any of this when the termperature is
above 50 F or so.
Anyway, any suggestions would be appreciated.
