ABS & SERV light on but not always?

[MonacoDan]

hi everyone, basically my ABS and SERV light sometimes comes on while I'm driving but if I stop the car and start it again the lights disappear, any ideas what's causing this?
P.s I had the N/S abs sensor replaced about a month ago

Any help would be very useful, thanks

Needs plugging in again to say for sure mate. Sounds like a target issue to me

I have this sometimes when my OBD dongle is plugged in

As above but more than likely to be the target on the driveshaft, they are well known for cracking causing ABS problems

Right so i found some time to check it out, i figured out that the ABS light only came on when on full left lock or going over a bump when turning left, so the first job was to get my neighbour to do a diagnostics test (he owns a garage ), it said there was something up with the O/S ABS and he said to check the rings and give em a clean, so today i jacked up the car and the rings looked mint...

i also checked the cables weren't loose etc, all fine.
since i took the car off the jack the ABS light is now on permanently, what's going on? anyone any ideas?

Btw it was the O/S ABS sensor that was replaced not the N/S just check the receipt.

Does cruise control still work? Could be the brake pedal sensor.

EDIT: Whoops. presumed it was a 182.

hi,

I have similar problem ABS, SERV and TC comes on if stuck in traffic for longer than 20 mins with lots of brake and go. Once the lights are on the brake pedal is kind of stuck at top. I simply switch off and start again and warning lights vanish. How expensive to replace ABS rings?

Thanks
