Hi Zep,
Sorry I may have confused things here. Basically with the original sensor, on start up the light would sequence and go off but occasionally come back on intermittently whilst driving. A quick on on off on the ignition would reset for a few days. This then happened more often until I had an mot and the test centre used a shaker deck ( to check the ball joints I'm told). After this the light stayed permently on so had the diagnostic and swapped out the sensor. This has made no difference and light still on.
Hope this makes sense?

Yes, thanks. For my money, the used sensor is as broken as your original I’m afraid.

Afre you a gambling man?
The new sensor is £85 versus cost of trip to dealer (your time + fuel + their bill).

If what your suggesting is just buy another new sensor (which nobody seems to have for available bty) and fit that, I still have the potential issue nobody's yet confirmed whether the warning light goes off automatically or whether I would also need need a dealer visit, my time + fuel + their bill to have light reset. Thing is, for all I know the used one could even be working which was why I posed the question...

Hi Matt,
Thanks. Yes I think the colour works well with the car. That said, they are such a great design I haven't seen a colour I don't like on them.
Nice to know I'm not alone down here. Do you currently have a Maserati yourself?
Yes, after regretting the sale of my Granturismo in January, we went out and bought a 4200 in, I think, April time. It was relatively cheap, for a reason, it’s a bit of a project. I’ve done many of the same things as yourself, service kit, oil pressure switch and we’ve got an x pipe to fit.

currently looking a bit sorry for itself as the heater matrix emptied it’s load in the footwells, so the dash is out!

Ours has got the suspension light on too, I might be barking up the wrong tree, but I was thinking it might be an ABS sensor fault. Not investigated it much yet though.

Indeed I was suggesting that. As stand-alone operation to cure the issue it might work.
If the sensor is surplus to requirements I am pretty sure that you might sell the sensor here.

The course of action I can see is buying the new, updated part new (as they are shared with Ferrari supply should be ok) and fit it. Based on what you have said, if the sensor is good, the light should go off on its own.

If its the abs sensor thats at fault you will normally get the msp not available light on and abs fault light on. You will also loose the hill hold facility.

Abs fault light can be cleared with torque pro app and a suitable bluetooth dongle. It will keep returning more and more often if the ABS sensor is at fault. Its around £550 a corner if the sensor is faulty although it is usually play in the bearing on the 4200.

Totally agree with you Zep.
As an ex MOT Tester and used a shaker plate which is the best way of inspection for suspension on a vehicle that didn't cause the issue as it's far gentler than the average British road.
As a Maserati goes it should be a cheap fix.
I would then get it scanned to clear historical faults.

Stangely, I have had the MSP Not Available Light and ABS warning light come - not often, just a couple of times over the last 6 months. each time a switch off and on with the ignition cleared the lights. I'm gussing as I've got the pre existing issue with the Lateral speed sensor it must sometimes upset the MSP / ABS. Given nothing other than the Lateral Sensor was picked up by Maserati full Diagnostic the other day it maybe yours could be a sensor aswell.
Would be good to meet up for a social distance meet at some point given we're so close to each other!

Hi Phil,
Thanks for your input and to everyone else. I think the MOT Shaker test probably finished off the intermitent sensor as after that the light stayed on all the time, so to does the used replacement.

I spoke to the MD today who carried out the Diagnostic. They suggest another plug in to clear codes and then drive it. If it comes back the used sensor is also faulty. Couldn't get a definitive answer from them as to whether you need to clear the ECU regardless to get the light off or whether the light goes off automatically once a working sensor is detected, so have had to bite the bullet and book her in again...

Not sure what I'm going to do if it turns out to be a dodgy used sensor as after hours on the phone and internet today nobody appears to have a new one available. Tried everywhere I can think of even the Ferrari specialists can't help. Would there be anyone on here that could supply/ source a new sensor for me should this be the case? P/N's were 232867 or 175221

I don’t know who you have spoken to so far, but Ross at Meridien Modena will be able to tell you if there is any stock at the factory. If there isn’t then you are stuck with the used option. @breakeronly might be able to assist.

As Oneball has said and given your previous experience, it should clear the light when a working sensor is fitted. Otherwise it wouldn’t have been intermittent in the first place.

Not sure I really want to go down the used route again as already out of pocket with the one I bought. Used parts seem not to come with guarantee. Good to know your light went off without need of a reset though.

Id have thought eurospares would give you a refund if it’s faulty.

The light will reset itself, no need to clear. Mine will come on if I'm on a bumpy road, more so if I have the Sport button pressed. Not sure it's applicable to your situation, but washing under the car will guarantee the light coming on. I have made mine go off by jiggling the wires going into the top of the shocks. Since you have traced the fault to the sensor, this may not be helpful.
Beautiful car BTW.

A new sensor will put the light out.
Historic faults will remain in the ECU but I'm sure a Launch X431 will clear those.
Good Luck getting a sensor.

Thanks Guys,
So from what's been said here the light should go off automatically once a working sensor is detected. Does that mean it's likely to come back on if I don't have the fault history cleared on the ECU? So far I have racked up £250 in diagnostic charges so don't want to have another if not entirely necessary.
