Dealer stripped my bolt too. They try to tell me it was my fault. They had car up on lift. Showed me the bolt that had little hairs hanging off of it. I said "you JUST stripped it. Look fresh metal". They said no and wanted to charge me an hour labor to get it out. I told them to lower my car and bring it around front. Went to parts counter and bought new plug and oil. Went home and got it off right away. Used vice grips. Got plenty of bite so it was no problem.

I hate the dealer.

I replaced my bolt just as a precaution last year. Some people haven't a clue what torque specs are and why they're important. They either finger tighten things or beast them on. Then you have the complete noobs that add loctite red to everything, on top of stripping every bolt.

Back to the OP, user error.

If anyone should have stripped, it should have been mine 2 weeks ago. I haven't drained my oil in 4 years ever since I started the oil extractor. 2 weeks ago i decided it was a good idea to actually do a full flush. Came off fine, went back on fine.

My Ride: 325i
Thanks Flash,

A stripped hollow bolt was my problem (BMW 325i), as you stated is typically the problem with these cars. Your pointer proved invaluable for me.
I backed out the top half of the bolt by applying some pressure under the head with a thin screwdriver while using a socket wrench to unscrew it.
Then I stuck in an inexpensive bolt extractor from Canadian Tire and eventually got the bottom half of the bolt out.

I initially assumed the pan threading was stripped too, but nope, it was the bolt. But not so obvious, since it just spun round and round without dropping out, loosening or tightening. Who'd have guessed it?

Needless to say, I'm breathing a big sigh of relief right now! I'm glad BMW uses a hollow bolt!

Oil Drain Plug stripped - ****ing kidding me BMW engineers?

Why not just leave it in for now and drain the oil from the level sensor?

When I purchased my M3 pre-owned from a dealer, the oil drain was leaking due to semi stripped pan. They tried a heli coil first and it kept leaking, so they replaced the entire pan under warranty. I was very nervous about the helicoil and the little metal bits that it generates. Ever since, I change it myself and use a great torque wrench to 18ft lbs. Also very important to use the metric allen socket wrench bits. I've heard some using vice grips and an L allen wrench (bad)...

-good luck...

I was under the impression that this method is deprecated, because not *all* the oil is remove and (thanks to gravity) **** stays at the bottom? 4 years seems a bit long, but I suppose that's why we have an oil filter.

OP I had a post literally a week ago about my bolt being stripped. I ended up taking it somewhere and let them deal with it lol!
