Thanks for answering Blownvette. As a V10 owner, you were automatically included in the request.
You only had a single glow plug fault??? For some silly reason, I was thinking you had a multiple glowplug fault. That is 100% My bad. I didn't read your reply carefully enough. I see you stated it clearly.
I was thinking that an electrical or controller fault usually had a pair of the glowplugs go out together and assumed that a single fault usually meant that the glowplug itself was bad. <<Not necessarily true.
Well, I am glad I asked for further input. Something seemed off, so I wanted some more input. Little did I know that it was going to be me that was off. lolz.
To the OP: Blownvette is part of the core group of helpers on this forum. Or, to put it simply. If Blownvette says to he has seen "this" and that you should check "that", then you should check "that."
The sad part is that tracing and checking for electrical faults is beyond the scope of many owners. It is a specialty. But, lets make it really easy with a checklist. The OP or the garage the OP went to could check (if the OP can not).
Actually it might be pretty simple. Please double check this Blownvette. (thanks!)
1. Check every fuse under the seat/near the battery.
2. Would you recommend checking both the left and right hand fuse box and and the ones under the hood also? I am just double checking myself at this point. One goof a day is enough!
3. Check the relay in the trunk. I would assume we would want ohm's checked and the contracts visually verified as clean and non-pitted.
