Help! E32 problems after jump starting (hazard lights blinking)

[bayerischeNT]

I was in London for a few months and finally got back up to where my 94 740il was stored as I plan on doing a 6 speed swap this summer. I jumped the car and the hazard signals stayed blinking as soon as it turned on. I looked over the relays and noticed the blinker relay was ticking and because I needed to drive the car back at night, I removed the hazard light fuse which solved the problem temporarily. I am wondering what could be the source of the issue as well as if anyone has encountered this before?

In addition, when I pulled out of the garage space I noticed a rubber ring that looked like a donut sitting on the ground which had broken and fallen off sometime while I was away (I'm guessing due to the old age). I attached a picture of the piece and am wondering if anyone knows the name of it as well as what it does?

Thanks for any input!

Hi. My guess is the "crash relay " part 1388 533 has given up. I had same issue a few months ago. Either that or the indicator relay is a goner. That part that has dropped off looks like a support ring from the rear muffler. Hope I'm right and that helps a bit. Good luck

After reconnecting the battery on an '86 E32 we've also had the hazards blinking. That was fixed by locking and unlocking the driverside door with the key..

There was a series of defective crash alarm relays, the brown one in the fuse box left hand side https://www.bimmerforums.com/forum/s...ating-flashers
The 'donut' could be this one on the rear muffler http://bmwe32.masscom.net/sean750/dr...ng/Image28.jpg

Thanks for the replies! And as for the donut, it looks a bit rounder, almost like a really thick 2" o ring

I agree that's likely an exhaust donut. It's possibly even a non-BMW exhaust donut that someone made use of, when the stock item couldn't be found.

On many older BMW's, after reconnecting the battery cables, I've often had to push the hazard switch twice, to shut them off. I'm sure locking and unlocking would accomplish the same....unless, of course it's a bad relay, as shogun suggests.
