Mercedes Vito 639 111cdi long

[Andrew Roberts]

Good day allI have
Introducing myself but could not find how to do itSo I am in north Wales on my third Vito
Bought this one as an mot failure on some easy jobs been standing for three months

Done the mot work ,I had to snap off abs sensor to take front hub off to dismantle the wishbone off
Cleaned out hub for new sensor(eBay)
My problem is after putting back together is after driving 50 mtrs ,abs and traction lights come on,two second after brake warning light stop engine,same thing again ,I have replaced ABS pump with same Bosch and Mercedes numbers,
Cannot bleed brakes ,correctly,with are intermittent
My important question if someone can help is. Does the pump need to be programmed?
Thanks in advanceandy

Was it a genuine Mercedes sensor you fitted?
Quite a few decent diagnostic systems will read the wheel speeds. Sounds like you have at least 1 giving duff info

 

[Andrew Roberts]

Thanks for the reply blobcat,no not genuine Mercedes sensor,one from eBay £18
Then tried local parts shop £30
I have had my son's mate with a foxwell Mtlook at it it did read right hand wheel
I have it going in to a mechanic ,he has a computer to read etc.
I have seen it mentioned here before,about should be Mercedes sensor?

 

[Andrew Roberts]

Ok thanks blobcak,no one sensor itried £18 from eBay then tried another £30 from local stockist onto right wheel,where the area of repairs weremy lads friend looked at it with foxwell my reader,mentioned right wheel,

 

[Andrew Roberts]

I am just wondering if ishould collect another abs sensor from Mercedes vans which is 80+ miles drive one wayor pick one up from eurocarparts 20 miles away ,Bosch for £62
Any advise much appreciated thanks

 

[MinionBob]

can you not swap L and R sensors??

 

[Andrew Roberts]

Minionbob,
No the end is welded in there with corrosion,mind you icoul try soaking it thanks,I have a spare cheaper one now

 

[Andrew Roberts]

Is it right then presuming the old abs sensor on the left is original that only the front right has to be a genuine Mercedes sensor,
And I could put aftermarket on other wheels?

[Big Cheese]

I had the same problem with aftermarket sensors,fitted a genuine sensor & all was good.

 

[Andrew Roberts]

Oh right thanks big cheese
I am presume that a Bosch one will do from eurocarparts originally £90 but with discount £62
Big cheese,was abs traction brake warning and no speedo?
Thanksandy

 

[Andrew Roberts]

Hi all again,
I am wondering if someone could shed some light on the issue I have with abs light /traction light/brake warning and no speedo.
I have busted original abs sensor taking the old hub for taking a ball joint of
Put an aftermarket abs on then probs with abs pump (blockage)
Then was advised on here to put original abs on (front right)
Question is I can get one from eurocarparts locally for £62 collect tomorrow ,
This is Bosch.
Would anyone know if this would be the correct one?
Have been told by eurocarparts it is OEMthanks in advance. AAR

 

[Big Cheese]

I ordered mine from Mercedes in Birmingham so not sure if the Bosch one would be oem but it cured all the faults that you list above.

 

[Andrew Roberts]

Thanks big cheese,yes I've had another think and ordered the genuine from Mercedes deeside they're getting today I'll collect it,

 

[Andrew Roberts]

Here we are .
I have collected the abs cable from Mercedes deeside this morning,about 3.5 hours
But up to now worth it,
Usually came on after 50 mtrs drive but today took it a few hundred yards
Speedo works and no lights abs traction and brake warning
I. Would like to say for the advice
It booked in for mot on Thursday may have a little walking on both inner wings and steering column universal joint ,I have that piece ready

There is a chap on youtube; Diagnose Dan. Is early videos are very good. In one of them he compares the output of a genuine and aftermarket sensor (MAF, perhaps, cant fully remember) and shows although they both work, the outputs given to the vehicles are very different and this will result in different levels of vehicle performance. Its worth a look.

Perhaps ABS sensors suffer a similar problem.

 

[Andrew Roberts]

Right thanks,
Like I said before a local person was going to put it on a computer,he's not cantacted me yet,so I put that on today,so mot Thursday so go from there,I'll book them to bleed brakes
