I took my 96 328 convertible to a "German Car" shop, (BMW, Mercedes and Audi), for a simple oil and filter change. I go to pull out of my garage the next day and there is a fair size puddle of oil on the garage floor. I look around under the car and it seems to be dripping from the oil drain plug. I take a rag to wipe it off, and the plug spins in my hand!!! They did not tighten the plug!!!
I don't have any ramps, but was able to wedge myself under the car enough to hand tighten the plug with a 17mm box wrench. The leak seems to have stopped.
My question is - Is hand tight ok? Do I need to use a torque wrench?, (which I don't have).
Needless to say I won't be going back to this "German Car" shop. Thanks in advance for any help.
You'll be fine tightening by hand. What a bunch of bloody idiots!
I'd be going down there for a refund on the oil they charged to to put in!!!
If it was an inspec1 service, then stick to BMW dealers. If it was just an oil and filter change then it's pretty easy to learn how to do this at home.

Wow, what morons. I dream for the day someone does such. I get bent over by my mechanic so often, I would love to have a reason to return the favor.
At any rate, when the shop changed your oil, they should have changed the copper washer that goes on with the drain plug. Take a flashlight, get under your car (best you can) and make sure it is present. If so, you may tighten down until your heart's content, as this should prevent over tightening. Then go down to the shop, and kick some a.
Thanks a bunch for the help guys. I will check for the copper washer. It didn't leak at all last night after I hand tightened the drain plug....
This was just an oil and filter change, so I felt ok in trying out an independant shop.....Oh well.
Last night I was pretty pissed off, but have calmed down today. I will be visiting the shop to voice my displeasure, as well as writing a letter to the owner. We all make mistakes, its human, but this is pretty lame.
This is my first BMW, so I was hoping to establish a long term relationship with a good shop. Looks like I'll be going to the big dealer in the area for service. They do a good job, but as a small business owner myself I try to support the little guys if I can. You live and learn.
Get this: I had my oil changed and the next day was scooting down the interstate at night in freezing weather. Then my oil light came on. So I pull over, and see oil splattered all over the engine and NO OIL CAP! Buncha idiots! Luckily, the cap had slid down to a lower part of the engine, so I fished it out and scooted on home, of course, a quart or so low.
Juffy lube did this, tightened it too much, so it snapped. Thankfully, it's a hollow plug, so it's easier to remove than a solid plug (solid plugs requires drilling and you'll probably just end up taking the oil pan off...)
I wasn't aware of a washer, and I thought of adding a rubber one myself next oil change, but you can certainly strip threads or break the head off the plug if you overtighten. REALLY FINGER TIGHT, or really lightly with a wrench or plyers is plenty.
two is that you dont undertighten , hand tight might be too little
three the correct way is to hand tight plus a half turn, no more no less, the reason is so you dont break the bolt as shown above and two is because you can crack your oil pan, trust me ive seen it a couple times on cars, (not in person, but ive seen what it looks like when they have to repair it)
