I've only had my z4 a few days now, love it but I've noticed its been pulling to the left especially above 60mph and the steering feeling intermittently jerky but not always?? Also the DSC light flashes once on startup now and again but not always I'm very confused, been looking around the forum for answers, scary stories of abs pumps costing an arm and a leg are mentioned quite often. I'll get the alignment sorted and go from there, but the alignment being out doesn't explain the intermittent jerky steering on the motorway. Any suggestions guys?
