If you bike is out of warranty and you need to buy just the switch part, I have several on hand all brand new. $100 shipped .. BMW does not sell just the switch part that is defective. they want you to buy the EWS and the switch part. that is about $185 and you have to wait on it from BMWAG. USA dealer cannot program a EWS4 module. I can, but there is no need for you to have a EWS4 to fix the issue. Its just the switch part that has the defective nylon push button that is causing the problem.
