ABS and MSC sensor

[Sparks]

I have the above lights on.
As it’s an MOT failure it needs sorting.
Unfortunately due to a stroke and a heart bypass, I am currently unable to drive but want to make sure the car is ready when I am.
So, my question is, how much of a job is it’s to replace the sensors and would this most likely solve the problem?

If it's just the lights, first probable cause is a dying battery. So either charge or replace if it's known to be old.
Sensor is integrated into the hub / bearing so it's not cheap but not too hard I believe

Thank you.
as it’s been at least a year since I was allowed to drive a flat battery I’d a possibility.
I’ll try that first.

That would absolutely be the first stop then. In fact I'm amazed it even starts after a year

No idea where you are but if you need any assistance, I'm sure there are those around that would happily assist.

The battery is an issue. The indicator that it’s the physical bearing sensor is if the lights stay on the dash after you remove the key or when you unlock the car.

You will also get a juddering from the abs as you pull to a stop.

Fitted, mot and vat you are looking at a grand.

I’m in west Oxfordshire. Nearest garage with the right computer is in the next county.

Plenty of capable friends should i decide to do it myself.

I had this, its usually the sensor on one of the 4 wheel hubs that needs replacing it triggers ABS and MSC lights. Check these first before you rathole on anything else. if I recall correctly it was about £200 for a part, an hour labour and a reset with a Leonardo or Maserati dealership device.

usually rear inner hub, closest to the ditch, or one that hits the most potholes that goes first.

I have exactly the same lights (abs and msp) . I’ve changed the front right hub where there was a grumbling bearing and these lights came on immediately. the sensor wire is the same colour on all the hubs so I’m guessing it’s not a compatibility problem. I drove it like that for a “while” , got the front discs skimmed as they slightly out of true, drove it out of the mechanics and a red gearbox light came on resulting in not being able to change past 2nd with either the auto or the paddles. Could it be the abs pump that’s faulty , screwing everything up? I can get gears if I go to neutral, rev it and then pull the up paddle. It goes directly into the most suitable gear for the engine revs. It has no problem changing down from this. some one help!

Have you had it plugged in to see what codes are stored?
Without that it is just guess work.
The ABS system will give input to the TCU so it is a possibility that it could affect gear selection.

I get the replacing a grumbling bearing doesn't need diagnostics but were there no warning lights before you replaced the bearing with a new part of correct part number?

Yep that’s exactly what happened. Bought from sopranoeve. Brand new. today I swapped over the wire from that hub to another hub that I have which was working perfectly and a diagnostic of the abs sensors have all the wheels doing 1.75 kph Which is a default failure code. This was not a Maserati system he was using. I do have fault codes from masertell and I’ll upload them but it doesn’t say anything about the abs pump. Thanks again for any input. (Diagnosis at md £211 + vat) so I want to try and avoid this, but if I can’t get the fault sourced I’ll have to bite the bullet

A lot of hassle I know but I’d put the old bearing back on and see if the faults clear when driven above 10mph or at least plug it in and see if some faults go.

 

[Neil robinson]

the old bearing unfortunately had the wire snapped at the base with no way to join it. It literally crumbled in my hands. I put a replacement one on with the same results as the new one

Oh right that’s a shame.
I’d spend the money on some diagnostics at the main dealer, I had a ‘specialist’ try tell me there were multiple ECU faults when their diagnostics wouldn’t communicate.
The main dealer told me the faulty abs sensor in 5 minutes aswell as % clutch wear etc

Roadbed sensor is not the hub it’s the box below it behind the hub.Think it’s called the vertical acceleration sensor from memory.

I like to think that we gave good honest advice when I worked for the only Maserati Dealership in NZ when we were Torino Motors before we got taken over by the Winger group.
That then sealed my decision to leave.

Thanks all for the input. It looks like dealer time

It isn't easy to find a decent garage, another specialist have been extremely helpful and honest - Migliore in Bromsgrove, so credit where it is due.

I’m beginning to feel like Sherlock Holmes. On the way to the mechanics to replace the first hub about 50yds from his garage I hit the mother of all pot holes[ on the rear n/s wheel, taking a bite out of it. Could it be this that has caused the error and not the new hub? I didn’t make the connection until rereading this thread. This really has been an epic. QUOTE="conaero, post: 927467, member: 4"]

Does anyone know how to replace the roadbed sensor on the rear n/s of my 4200 (vertical acceleration sensor). Thanks for looking neil
