mneth1986 Posted June 2, 2015 Report Share Posted June 2, 2015 (edited) Evening all, I have a strange DSC issue with my 330 that's driving me mad! It started a few weeks ago when exiting a roundabout the dsc light flickered, I didn't think too much of it as I was driving reasonably hard, my rear tyres are pretty low so put it down to that. Since then the issue has got progressively worse with the dsc light flickering and causing hesitation (like your doing a massive wheel spin) whenever I'm turning left (never right) or under hard acceleration in a straight line. It's been at my local garage for a week, no fault codes when scanned. We've also done a live test on the wheel speeds and seem to be normal. The car drives perfectly when the dsc is completely switched off, could it be a module problem? Help please!! Thanks in advance Edited June 2, 2015 by mneth1986 Link to comment Share on other sites More sharing options...
mneth1986 Posted June 3, 2015 Author Report Share Posted June 3, 2015 Bump, anyone had this at all or any thoughts ? Link to comment Share on other sites More sharing options...
Jay. Posted June 3, 2015 Report Share Posted June 3, 2015 Have you had your tyres replaced since the initial Occurance? Link to comment Share on other sites More sharing options...
mneth1986 Posted June 3, 2015 Author Report Share Posted June 3, 2015 Hi Jay, I haven't done yet, they're not completely down to the tread bars but certainly pretty low. My mechanic kind of suggested that it would be unlikely them, but I guess I should eliminate that. Link to comment Share on other sites More sharing options...
Jay. Posted June 3, 2015 Report Share Posted June 3, 2015 dsc is most effective with tyres that are half worn or better. I've certainly noticed on mine if the tyres are down on tread the dsc is very controlling. Link to comment Share on other sites More sharing options...

I've certainly noticed on mine if the tyres are down on tread the dsc is very controlling. But as bad as undriveable? I literally can't go left with the dsc on, it thinks the wheels are constantly spinning, revs all over the place and just won't go. Thats what makes me think it's more than tyres. Cheers for your help though dude, might as well change them as it's got to be done Link to comment Share on other sites More sharing options...
Jay. Posted June 3, 2015 Report Share Posted June 3, 2015 hmm can't say its been undriveable as such dood. maybe a wheel speed sensor on the limits of its values whilst stationary, or could be the pressure sensor in the engine bay. neither are particuarly expensive to replace.

mneth1986 Posted June 3, 2015 Author Report Share Posted June 3, 2015 Yeah i have to turn it off everytime, which is fine, but i can't sell it like that, which i'm looking to do in a few months. Definitely seems like a sensor type problem, the DSC kicks in even at 10mph without any acceleration. Weird that no fault codes show. Link to comment Share on other sites More sharing options...
Megadodo Posted June 4, 2015 Report Share Posted June 4, 2015 As long as the sensor is giving data within a valid range then there will be no errors, doesn't mean the notched part of the hub hasn't got a problem leading to the sensor misreading the wheel speed!

mneth1986 Posted June 5, 2015 Author Report Share Posted June 5, 2015 A BMW specialist local to me picked it up at 7.30 this morning so hopefully should get a diagnosis later today Link to comment Share on other sites More sharing options...
mneth1986 Posted June 5, 2015 Author Report Share Posted June 5, 2015 Heard back from the garage, it's the driveshaft corroded and rubbing against the abs sensors, similar to this thread http://www.e46zone.com/forum/topic/50383-rear-drive-shaft-repair-please-advise/ Quoted as follows Driveshaft end overhall x 2 £450 Rear ABS sensor x 2 £195 Labour £360 + VAT=£1200 Thoughts on the price?
