Software Update - 'Just like a laptop'

Getting the same issue now pop up. Steering feels weird and the error is as above.

Sounds like it might be an abs sensor. It’s going into a local garage (all out of warranty) for a quick diagnostic check on Wednesday. Will report back.

I was getting phantom drivers rear side parking sensor warnings on reverse and I do know there’s a little condensation in a rear passenger side tail light.

Other than that no clues.

All discs and brakes were changed last year.

99% sure it’s wheel sensor. Had mine done last week. Caused spurious power steering activity and severe limp mode and gear box malfunctions. There are several threads about it. Seems a problem with sensors breaking down. Mine was rear OS .. but my Mertech guy says they’ve had issues with front. Exasperated by road potholes.

Not a difficult job. Several YouTube clips.

Also Febi Bilstein from EBay only £35 rather than £150 Merc part.

Are they expensive?

if you paste those numbers into eBay you’ll see options. Just need local garage or friend to read the OBD error odes and determine which sensor..

Must get myself some form of diagnostic tool. I do plan to keep the MP for a fair few years. Be worthwhile I think to cut out a step or two on the way to a fix.

It’s only got 23k on it for a 2019 v250 and tbh I really like the car.

I can confirm rear passenger side abs sensor is faulty. We have reset the code meantime and will get her booked in next week to sort it out. Thanks for the help and information.

Update car booked in for Tuesday. Tech wants to look at the wheel bearing to see if that’s causing the sensor to fail.

It seems intermittent. The alert will clear and then come back on again later.

Rear wheel abs sensor replaced, charged for part fitting, diagnostic and removing a pint of oil to stop the annoying “too much oil” alerts.

Hopefully that’s the last I’ll see of both. £190. Probably a tad more than I was expecting. Hey ho the joys of motoring.
