ABS cut-off switch

[Porker]

you might have really hard springs which would make this happen more htan normal (something like 140F/70R)

I should check with Intrax what springs they have fitted. That would clarify the harsh ride as well.. How does yours ride with dampers halfway?

If there was something wrong with a wheel speed sensor you'd have a light on I think.

Mine are 120/60 and springs are hardly any more harsh than 100/50. Damper setting s don't really change the ride much at all and at half way they are at a good road setting, spring rates are where it's at.

If I were you I would get the suspsension looked at

A cracked or damaged reluctor ring can give you ABS that jumps in too early. Not common on BMW's though, I must be honest.

[shimmy]

where is your reluctor ring Gareth?

For you Shim, it'd be my reluctant ring...

I am running 130/80 springs. No issues with ABS and mind you I have -3.5 front camber.

As shimmy and others suggested, check your suspension setup.
I would prefer to know exactly what my suspension has, the "nordschleife setup" is too vague.
But then again I compiled my suspension on my own.

Correct, I've contacted Intrax, hope they can find which spring rates they have fitted to mine. Thanks for the advice!

Unfortunately my car is in Belgium and I'm in Switzerland.

Got this info from Intrax, doesn't seem too hard to me?

Front 120kg +1006 (helper spring)
Rear 60kg + 1006 (helper spring)

Length of the spring:
Front 150
Rear 220

Same as mine......no Abs issues my end.

I have 140 kg/cm front springs & RS29 on my e46 m3and abs only cuts in if I drag the brake off the take off of pflanzgarten. This activates the abs if I go for a 2nd dab in the compression as wheels lock for a moment when you leave the 'jump', hence abs having a fit.

Just came off brakes a little earlier and all sorted.

Only road I have ever really had it on is a Scottish road at glenshee but it has very big crests/jumps so same as above and not a problem with abs system
