Car Died while driving

Wife was driving 2000 Jetta TDI this evening. Engine shut off while she was driving. Engine will not start. However it will crank over.

When I tried to start it, I noticed that the GLOW PLUG LIGHT WOULD NOT COME ON. Any ideas on what might be the potential culprit? Thanks

Relay 109 failure. $20 relay from dealer. Easy replace yourself.

Thanks N1das. I appreciate your valuable input.

Is there anything in particular that makes you think it is the 109 relay? Where exactly is the 109 relay located? Do you have a photo pf where it is located?

If, by chance, this isn't the problem, got any other ideas what might cause this scenario? Thanks bud.

This shows the location,try removing it then reinstalling it.

The indication of no glow plug means the ECM is not powering up, this is typically relay 109, if you change the 109 and still not working you have a power issue related to powering up some electronics (like the ECM) needed to run the car. chances are relay 109 will fix it, they were high failure rate in early mkivs

AND be sure to followup on this thread with the outcome, thanks

Relay 109 or you have a crappy master battery ground. Both have been the cause of a crank-no-start scenario for me.

Changed 109 relay....problem solved!! 2000 Jetta back on the road!!!

Unfortunately, now I have another issue.

The relay I used to fix the Jetta came out of my 2001 Golf. After I pulled the BAD relay from the Jetta, I put the bad relay in my Golf to see if I might get lucky.

The golf did NOT CRANK OVER!!! It was completely DEAD!!

So, I then put the GOOD relay back in the Golf. Still DEAD!!! The Golf will NOT CRANK OVER at all!!! ....even with the good relay in it. The golf is now COMPLETELY DEAD IN THE WATER!!! What the &*$#?????? Anyone have any thoughts???? I am very confused and frustrated!!!

Did you knock off the clutch signal or something while down there? Shouldnt have caused an issue like that, are you getting dash lights, but no crank?

Thanks Steve,

the car has automatic tranny.

All the dash lights come on. Will not crank over.

I will take a look and see if something appears to be knocked off.
