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.

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!

No, it's not

Top extract and fill is, in fact, a recommended oil change method at Mercedes-Benz. It's why I bought an oil extractor for my 2006 E320 CDI years ago. It works fine as long as you do your change with warm/hot oil. You NEVER get all the oil out, anyway. What you miss with a top-loaded evacuator is miniscule. Recall that the oil drain bolt female flange is NOT flush with the bottom of the pan anyway, so a shallow pool of oil stays behind when you bottom drain.

MB tech bulletin:
************************************************************ ***

Date: March 2001
Order No.: S-SI-58.00/118
Supersedes:
Group 58
SUBJECT:
ALL ENGINES
APPROVED OIL EVACUATION EQUIPMENT
The purpose of this Service Information is to inform dealers that Approved Oil Evacuation Equipment, which is used to extract used engine oil from the engine via the oil dipstick tube, is now available for order. Mercedes-Benz engines are designed to allow the extraction of engine oil from under the hood via the dipstick tube. The engine dipstick tube has an enlarged cross section, plus a formed extension at the top end where the dipstick is inserted and the approved engine oil evacuation equipment interfaces. The opposite end of the dipstick ends just short of the oil pan bottom, thus engine oil can be extracted via the approved oil evacuation equipment by using the dipstick tube. Additionally, the engine dipstick tube itself is the conduit through which spent engine oil is moved to the oil evacuation equipment.
In addition, service and repair components for existing approved oil evacuation equipment is also available.
Note: Because the engine oil dipstick tube is the conduit through which spent engine oil is extracted, inserting tubular probes through the dipstick tube is NOT recommended.
Special Note for M-class:
Due to the location of the vehicle frame and suspension components, the draining of engine oil via the engine crankcase oil drain plug is not recommended, since this can lead to engine oil coming in contact and subsequently be damaging to the rubber suspension components. Thus, it is strongly recommended to use the approved oil evacuation equipment contained in the Service

************************************************************ ***

Now I get to use it on the 2006 E46 M3 I bought used Fall of 2012. I just did my first oil change (only do a few thousand miles a year). Had the car up and only then discovered the yahoo engineers at BMW had installed a 6 mm hex head nut. Had no such wrench (just a metric Allen wrench set), so off I went to buy a set. Then I discovered...a stripped oil pan bolt. This was followed immediately by speculation on the questionable ancestry of (1) the BMW engineers who specified such a stupid thing and (2) whoever over-cranked it and caused the strip.

Put the car down and used my oil evacuator to suck the oil out. I measured what I got out. Right at 6 quarts.

The plus side is that getting under the car is a big pain with my ramps, anyway, so top-side is easier. I may replace that idiotic hex head bolt with a proper bolt some time, but I will be in no hurry to do it.

By the way, a few years ago the Greens in Germany were proposing that oil drain bolts in all oil pans be eliminated. Their concern was that a few people were just driving their cars out somewhere and dumping the oil on the ground instead of recycling. They wanted to make it harder to do that. It never came to pass (yet), so the drain plugs remain.

For future Readers of this post....Thw Moral is never do this (the quote) !!!!!!
I AM SUPRISED THE OP WAS NOT FLAMED FOR THIS........

And the Pearls are : before proceeding.....read a DIY oil change write up on your vehicle, always use METRIC tools on your BMW....and get a couple torque wrenches then torque to spec!!!!

You can order a oil change kit that comes with a new plug
http://www.ecstuning.com/News/BMW_E4...006/ES2550022/
Change the pug at every oil change.

With the kit I go to the local gas station and pay $20 to replace the oil.

I do this now because I had BMW change the oil once and they stripped the oil plug.

Good Luck.
