Has that car been up on blocks since new? It sure looks like it.

That does look a little strange are you sure that bolt is in the right place? I thought the "weird" bolts were on the upper part of the compressor. I'll have to go look at mine in a little while to see if it's like that.

Just in case you honestly don't know, it's one of the A/C compressor mounting bolts. Mine is like that, too. Makes it easy to access all three of them from the top. Why? I have no idea.

it is....

Since it is my car, I will reply

It is on the A/C compressor (fairly new) and it is one of the three bolts you loosen before attacking the adjustment screw to adjust your belts (something I just did recently)....

The car is on jack stands in the picture.... and it is not new, it has 183.9K miles on it (I took the picture Saturday).

I should have expressed myself more clearly...I know its on the a/c but I was wondering if anyone knew definitively why the doggone thing is so long. Ya know, like the cigar hose...it has a purpose for being, well, a cigar hose. I was hoping for a similar 'splanation for this. It's probably some attempt at German humor.

And, I have it on my wagon and sedan as well...and just did a belt change-out so, I don't think it's to make it easier to access from the top since you can only get on that thing with a wrench from underneath the car.

My guess is that Hazet or Stahlwille makes a unique tool that costs $96.00 and has something to do with this...

BTW a diesel engine that clean looks absolutely OBSCENE!

Ok then, how about this? MB got a really really really good deal on those extra long bolts, so they had to use them somewhere. Better?

Most likely the bolt this that long to add more holding tension, a shorter bolt may break from the vibration, or come loose.
I have seen this on other applications also.
More stretch better holding, usually by adding spacers.

A little German humor: it is a Torque Capacitor, i.e. holds excess torque until it is needed...

Russb, Do you remember what other items you have seen this application on ?
I can see a THINNER bolt breaking ... but your impression of a longer bolt holding tension better works with things like head bolts... but hanging the ' extra ' length outside the clamping area does not seem to comply with that type situation. And, if this were a thinner bolt it would introduce a better chance of vibrating... particularly hanging out unsupported that way...
I think there must be some other explanation....
