Hi All

Just thought I'd share my recent experience. For a while now I was experiencing intermitent issues with my iDrive, where the screen would change by itself to various other screens. Thinking it could be a sign that the battery was on it's way out I had it checked and despite being told that it was fine decided to replace it anyway as it was getting on 7 years old. Then I got warnings all of a sudden that my DCS, DBS and Tire Monitor had failed, also my indicators no longer self cancelled. Diagnosis was Faulty DCS Steering Column Sensor quoted second hand fitted $830 New $1500 (not from Dealer). I then came across the thread below and tried it.

Problem fixed for less than 1 hours work and the cost of 1 alcohol swab from the chemist. The optical wheel cover was covered in a crystal like substance that wiped away with the alcohol swab and problems all gone. No warnings, and indicators self cancelling again.
Needless to say I am one happy guy at the moment. Also no iDrive issues as yet either.

Attached Pic is of the crystallisation on the sensor wheel.

Glad it all worked out. +1 for e90 post and DIY

Just makes me wonder how many other parts are we paying for and swapping out that might just need a simple clean.
