E350 W212 Turn Indicators and Blind Spot Assist Fault

[ozibunge]

Hi All

During a recent trip from Canberra to Melbourne return, I lost my indicators and Blind Spot Assist (BSA) on at least 6 occasions. Not sure which fails first but 'Blind Spot Assist Inoperative' display message appears so I suspect it is BSA. The short term fix is to pull over when possible, turn the engine off and restart - like a re-boot. Grateful for any suggestions or easy fix solution before I commit to leaving the car at the local dealer to hopefully get it fixed under the extended warranty.

I just found a guy who had the EXACT same symptoms on a US forum, and the culprit was the STEERING WHEEL MODULE.
