E89 K-Can issues and EPS fault - nick9one1 - 09-19-2023 I wonder if anyone here has suggestions on how to troubleshoot this. This is what happened; Waterpump failed - was replaced. Car slipped on jack and damaged EPS motor. A water leak was also discovered a the top of windscreen where the bonding had failed (may not be relevant). At this point the EPS motor obviously needed replacing. 80A EPS fuse in boot blown - replaced. Replaced EPS motor only, PS was back but intermittent. Then I replaced complete steering rack as I thought maybe that was damaged too. EPS better but not correct. So this is where I am now; When you turn the wheel the force seems to vary. e.g. in the video I'm quarter turning the wheel and it is very easy, but when I get to the bottom it gets harder. The EPS is working the whole time but it isn't smooth to turn. There also seems to be a problem with the CAN line. Sometimes modules dont respond, and when you read live data e.g. vehicle speed it flicks between on and 'not available' as if there is a communication problem. This is the same with every module.
