w124 Rear ABS sensor issue / question(s)
 

Has anyone replaced or taken out the rear abs speed sensor out of the differential before? The guy I had working on my car managed to break mine off in a rather violent attack (judging from the teeth marks all over whats left of it). He was suppose to replace it but,


once I noticed the differential leaking and saw what had gone on with trying to remove it, I'm going to take it from here. I was trying to install the new one but is it suppose to be that tight? any tricks to getting it in? more importantly, I found that the Broken HALF is still in there!! Any suggestions on getting it out?!?! anyone have this happen to them?

If that part of the sensor is TIGHT in the opening, you can drill into it & pull it out by inserting a screw into the hole you just drilled.

Man this just happened to me on a 1995 E300D. Don't be too hard on your mechanic. I was prying and wiggling and the thing snapped pretty easy. What a lousy deal. How is that thing supposed to come out? The manual says, "Remove allen bolt, Remove speed sensor, Replace O-ring" . It is just a pressed in thing with an o-ring holding it right? There was no way mine was coming out. Maybe some brake cleaner and gentle wiggling next time.

I'm wondering weather i should just leave it in or get a new one. What does that due? Sense the real wheels turning and help determine when to activate the abs?
Where does that cord go? Is it easy to put in a new one ?

Thanks

This is an Industry Wide Affliction !
 

Both Front and Rear Sensors.

Basically "Plastico" that swells with Heat and Age,cementing itself into the
Orifice.

AeroKroil applied Judiciously Over Time tends to lessen the Breakage Upon Removal.

Those suckers are tight !

Biopete,

Find the Part Number in the EPC for your "Cord"/"Sensor" and look up the Price.
You will treat it as if T'were made of Diamond!

Ha. Welded is exactly what it looks like . I'm hoping the parts car has a newly replaced one. I Read abs overview in manual. Explains it all. Except the "destroy to remove" part.
The plug for that coord is under rear seat. So at least they got that part right.
If I get broken part out it won't leak oil will it?

Fast lane is out of order tonight. But my other place has it on back order for 70.50. 200 plus list price. Geez I hope they can get it.

S.A. that I am, I've never looked at the diagram
 

If that rear "Hall Effect Sensor" seals some portion of the "Pumpkin" (Differential)
as it looks at the "Toothed Wheel" for reference...
'Removal(without replacement) MAY leave an escape route for the Diff. Fluid.

I'm seeing $58. to $60. USD for 124 540 19 17 with online sources.

Hopefully posts 3 and 4 will quell the usual chorus of " Sue! Sue! "

The swelled sensor issue also extends to many engine mounted crank / cam sensors.

Rear W124 ABS sensor
 

biopete,

I didn't find It. (?)
I didn't even know I was (Supposed to be) looking for it.
[Until you sparked my interest]

EVERYWHERE,I look except:

1.MBEspecialists (Take out the E) in the U.K.
[They have a USED one???]

2."Stone"Auto (Convert the "Stone" word to another.)

3."Peak"Racing (Convert the "Peak" to another.)

[Two + Three MAY have New ones]

are showing NLA 2/12
(Which translates into the dreaded UnObtanium)
["Someone" should call Roy on Monday and ask]

There are two parts #s:
0265002208
AND
124 540 19 17

This is a Bosch manufactured part...So first thing I'd be doing is looking for the Bosch Part Number,and
trying to track it THERE.

This is a common H.E. sensor the only possible special
thing about it is the Mounting and the "Air Gap" between the sensor and the Toothed Wheel.

Will one of the Front sensors do? If the wire is Grafted
onto the rear plug?

Do we now need to Crazy Glue our New Replacement
Sensors into the Pumpkin to prevent Midnight Auto
Parts from giving Someone else a discount on Our
New Sensors?

IF (?) the Part is UnObtanium...
 

1.Could be temporary whilst MB seccumbs to a tertiary parts supplier's advances
because some "Bean Counter" in Stuttgart didn't like Bosch's price.
[CAUTION: If a New Part becomes available soon and it's made by Delphi,Do not
even break the seals on the packaging.Return it It's JUNK!]
2.A "Standardization" of Parts MAY be in the works.
[Read: Engineer saves Bean-Counter's nether regions by determining that ANOTHER model's sensor will fit and work perfectly.]
ONLY the exciting news of the "Upgrade" has yet to reach these BeKnighted,Untermenschen inhabited shores.
3.Some Bean Counter in Stuttgart decided:
"Screw them they're only 40% German anyway,
Let them pretend they're Cuban and make their own sensors out of used coffee cans whilst sitting on the Curb."
4.#3 is True and we're really Arointed!
(I REFUSE to use Cannibalized Ford sensors on my MB!)

How and why? Delphi is a parts arm of GM.

OOH ! Finally an Opportunity to link to this problem
 

See how well Delphi understands the phrase Quality Control.

Blue Efficiency injector recall? - MBClub UK - Bringing together Mercedes Enthusiasts

'Got to be the longest post I've ever seen.

We have more than a better reason to think Bosch was the Original Supplier for the Injectors and the "System" during the Taxi testing Phase in the Republic...AND at some point before the actual production run the Bean Counters switched the "Preferred" supplier to Delphi.

All sorts of Hinky things afterward,such as the Clownista who was in charge of
CS in the U.K. got moved to CONUS AND Promoted !
[Well you've gotta admit anybody that can get thousands of Englishmen to sit
still and be Screwed Day after Day Knows his job...]

Well of course, the failing Delphi injectors are round and are ABS sensors, therefore Delphi ABS sensors will have a high failure rate too!

The piezo injectors were ( Circa 09 ) new technology and share almost no technology with ABS sensors ( well, maybe a connecting plug. )

Using your logic, all Mercedes are "junk" because of the biodegradable wiring harnesses issues from the early to mid 90's.

Oh, and so many people cry about bean counters saving pennies when making parts, but these same people search for the least expensive parts when they perform repairs.

A modern car is a incredibly complex device, many people have no idea how complex the are.

But,You did follow through and attempt to Blame the poster for everything from
the Norwalk Virus to Childhood Obesity.

'Missed the Point, Pilgrim.

Delphi's lack of Q.C. is Systemic.

(And the Proof is that they Allowed MB UK to further Sully what was left of their
reputation with it's 'Orrible handling of the Catastrophe.)

AND Contrary to what you Incorrectly Alleged my thought processes to be...
Mercedes has provided quality products for almost 100 years.
[AND has ,upon occasion, "Stepped Up to The Plate" and accepted Blame]

GM (A.K.A. Delphi) [In it's management's and Stockholder's Mind's Eye] is
without flaw...AND being without Sin they admit to Nothing.Ever.

The Problem is the Consumers of their Products have obviously
failed in their duties as Involuntary,Unpaid Q.C. Engineers
to notify the Corporate entity soon enough to avoid Loss and financial liability.
