Re: Laguna 2 NSF wheel bearing replaced now ABS fault ?
....the fault is shown as no output from the Left Front speed sensor....
I didn't word that very well....DTT2000 doesn't actually say that...I should have explained it better
DTT2000 is in french and the fault description is : "Defaut Plausibilite - capteur AVG"
which translates to Default plausibility - AVG sensor
I can also see that there is no speed recorded for the AVG (Front Left) wheel, all the others have a speed next to them.
I'm pretty sure that the speedo signal comes from the Front Left wheel (NSF) sensor, I disconnected it once before and then the speedo didn't register.
Given that the ABS was working fine before the new bearing was fitted & that the speedo is still working I'm confident that the problem is the magnetic ring on the bearing, but as I said I can't understand how the speedo can work from the magnetic pulses from the bearing but the ABS can't ...who knows
