Hi, My turn singles have quit working. I replaced the four-way flasher on the console and what I understood to be the flasher as well but no fix. The four ways work fine. Is there another relay I should be looking for or perhaps the turn single switch at the column is the problem? Thanks for your suggestions. Bill

My 98 E00 is hard to start, shaking, smoking, and losing power I have to pump the pedal and downshift to keep her going also shows battey on the engine screen! In the last 5k mi. I`ve had installed all fuel lines and filter, mass airflow senser, fuel shutoff vavle? and a new waterpump and battery.
