The turn signal is always on when the ignition is turned on and goes from left to rig
hey quys.I have a problem, I have a W203 from
2002/04 and as soon as I turn on my ignition, my indicator to the right is always on sometimes it switches to the left. the lever o the steering wheel seems to have no influence, at first I thought that was the problem, so I disconnected the connector from the lever, but this makes no difference. my next suspicion is the Sam module in the back of the trunk. Does anyone have experience with this problem? thank you in advance!
Update: turns out my EZS had a software fault. I replaced the EZS and the fault disappeared. To this day 2025-11-28 i had no problems anymore. Still dont know what caused the corrupt software

Time to use your scanner to troubleshoot that with activation test.
Big chances one of your SAM was involved with moisture and will eventually need to be replaced.
Scan + test things first.
