Well. It was fun. I hope everyone had a blast, I know I sure did. I vow to eliminate all tomfoolery from my life and get my shit together. No more extended idling.
For posterity and for anyone who has a similar problem, the solution:
2 underhood relays were toasted. Relay "644" and "645." The resistors inside are supposed to be 560 ohms. Mine measured unstable in the 50-70 range. I replaced the relays and the car runs. I put back the old relays and it doesn't. So I'm quite sure it is the relays. I was thinking of asking Scotty but he would just tell me VWs are endless money pits (as they age) and laugh at me.
Relays were 50 something each at the stealer. I could have found the them cheaper but I couldn't wait for delivery.
Thanks and good day.
I've been watching South Main Auto Repair and was thankfully in the correct mindset. The moment I came upon the idling car I thought, "great, what's going to be screwed." I smelled hot stuff. Not total burning. But definitely hot. The hood was very warm. So I worried about affected or melted parts. I drove off slowly and went for about 20 minutes. It smelled better when I got back.What led you to checking the relays?
Happens to the best of us. I left my car "on", not running, because I had my VAGCOM running with my laptop. It was taking a while for the FW to download/install so I went upstairs and got caught up with work. Came down a few hours later and it just so happened I went to throw out a bottle into the recycling bin and saw the car with hood open, DRL's on. Totally forgot about it, but luckily I had my battery tender on it.We got back from the store. I was going to swing inside, feed the dogs lunch then go to Autozone. I got a phone call and completely spaced on the fact that it was running. 7pm I decide to finally go to Autozone.
These relays have resitors in them as part of the circuit for various reasons. Resitors don't like heat in general.The car is also 8 years old. In the best circumstances resitors will lose tolerance over time. I just cooked them.Does anyone have a theory as to why the relays broke because of the car idling for a few hours? they are in the fuse box and shouldn't get any hotter than the rest of the components....
My mother once left her 428i with the N20 (similar motor to ours) idling for like 4-5h and nothing happened to it, I would think nothing should happen... specially outside at a chilly 45 degrees, not in the middle of summer in Miami as it happened to the BMW....
That youtube channel has helped me before too lol
you must live in a nice neighborhood... my car would be gone within the first hourWe got back from the store. I was going to swing inside, feed the dogs lunch then go to Autozone. I got a phone call and completely spaced on the fact that it was running. 7pm I decide to finally go to Autozone.
