Esp/abs

[Madvlad65]

Looking for some advice lads/lassies. Front nearside tyre has very slow puncture every couple of weeks the tmps alarm sounds .pump up to correct pressure all good. So today as above happens now this .a scan with an obd2 meter no faults. Now the skidding car/ abs/tyre  lights stay on. So the question is could this be related to the tpms or something else like an abs sensor? Thanks for any help advice  2011 mk2 fabia vrs nearly 64k

Had this once before and it  turned out to be a bit of rust/dirt stuck in the drive shaft ABS cut outs a quick clean with small soft brush and some WD40 solved the issue for me hope this helps

Hopefully this or something similar. Coincidentally on the drive home no warning lights 🤔

I doubt you'll find any such thing, unfortunately. The ABS sensor 'looks' at magnetic patches on the inner face of the wheel bearing, not at anything on the driveshaft.

That seems like normal function for an indirect TPMS; when a tyre gets soft it activates. Oh and it is triggered by measuring relative wheel speed using the ABS sensors, so it could be a slow puncture or an ABS fault.

Also possibly a porous rim allowing gradual deflation around the tyre seal.

Leaning towards an ABS sensor myself. Mind you the amount of pot holes in my area the front nearside wheel takes a battering

Quick update.  drove the car today and noticed this. On start up no warning lights driving slowly 20/30 mph f****n  speed bumps press the brakes and felt like abs kicking in and the needle on speedo starts to jump up and down  then the warning lights come on also noticed slight fluctuation in headlight brightness when reving  and idol could there be chance this problem could be battery related?

I'd check two things straight away.  1) battery, which may be getting old and not holding charge and 2) your alternator and regulator as your power (lights) shouldn't be flickering.

(0) Battery and alternator connections are secure, then (1) and (2) above.
