anybody know?

my car definitely has a torx head "male" bolt holding it in- I don't have a tool and neither do any of the easy to get to local places.

I may have to order online- this is dumb!

or- what did you make work?

It is an E8. The female Torx sockets have an E designation rather than a T. It is best to get a 1/4" drive.

E8 and if you use an allen wrench as a drive in the E8 socket you can get your hand down there.
Make sure you have the hood release tab pushed if your car has one,so that the hood is in the all the way up.Lay a fender guard or blanket on the fender and dive in
another good reference in in the resource section diy articles on www.mercedesshop.com
m112 m113 cps r/r.
I hope you got the new one from autohausaz.com,they are down into the low $50's now delivered free
I think the market has bottomed

p.s. don't use loctite on the threads,you don't need it.

if you have one near you

Harbor Freight USA
725 45TH AVE NE
MINNEAPOLIS, MN 55421 call first to make sure it is in stock at the brick and mortar store,take a copy of the ad ,they will price match their internet price.
My local hb tools carries them in stock,so so should yours.
also most big Napa part stores carry them and some sears.

I checked with my Napa and he stocks the E8 and says you have one in rochester and the one in 45th ave has them in stock also.

thanks much- luckily I have hood off and time to order the e8 as it would be too much gas money to drive up there.

Two questions; (1) is this the first time the sensor has been changed? (2) are you going with the AB Elektronik part (which is OEM I think), or the Bosch part? Thanks

ordered part from autohausaz- not sure which one they use

first time it's been changes so far as I know

MarcusF

They carry the Bosch one. After you change it, post back and let us (OK, me) know if the Bosch is the same as the AB unit.
Thanks

I ordered one from Autohaus last week*. It will be here today (strike that - Just checked UPS.com and it's tomorrow). I'll take pictures of both (and post them) before I put the new one in.

* It was $40.10 (link) Best price around. Free shipping (would have been $8) with orders over $50, so I added a pair of wiper blades for $10, so for essentially $2 more than I was going to spend I got the blades. With the money I saved on parts (not to mention labor) it paid for the tools I needed ($8 sockets and $8 for the 1/4" extensions - from my local Harbor Freight).

PS. If you buy the sockets, I suggest buying 1/4" (I don't think a larger drive would fit in the gap between sensor and bolt) "deep" sockets as it made it much easy to get to the bolt, which is located rather close to the sensor itself.

tip.You all listen up to the noob
he will be driving circles around you soon,if he is that observant

also be sure to index the new cps to the ecu.Helps out getting all the systems back to copesetic conditions.

At first I read "cosmetic conditions" and thought if anyone ever sees this sensor again I will be amazed. But now I do need to figure out how to "index the new cps to the ecu" (maybe it's in the DIY link up top).

I did remove one wiring harness bracket from the left (drivers side) rear of the engine to improve access. And I'm using a 18" 1/4" extension. On that I have a "u-joint" and then the E8 deep socket. I taped the pieces together to prevent accidental drops. I also wrapped the u-joint with a rubber-band so I can guide it onto the bolt without it flopping around...

Dang I wish UPS was coming today.

PS. I did not need the male torx, so I went with this set and saved a few (more) dollars:

If you want better pictures, let me know.

Thanks for all the help,
