There is a tb on this. If the car is out of warranty like mine was you will need to DIY or pay pay pay!! I hard wired mine...problem side first then the other side shortly after.
The problem is poor design.
email me and I will talk you through it

i got the same message when my side-marker got screwed up, so check that...and seriously, dependin on the dealer and how well you know them, they will probably check it out for free, i mean youve been a loyal customer since you bought the car in 2002 right? (that wasnt really a joke...ive been with my dealer since 01)
the dealer with most certainly be able to fix it in about 5 minutes, if that.

One thing that has always puzzled me are the assemblies that are fitted with 1157 sockets. Since 1157 sockets are dual filament, I've never been able to make sense of why the blinkers are dual filament bulbs (considering the blinkers are only used for signals and do not remain lit).

Bulb number should be somewhere on the bulb base. If you still have OEM bulbs, than it probably doesn't have it indicated, but will only say 12V 55W or something to that extent. Most bulbs do have the bulb number indicated on the base though.

I had this same problem and the fix was exactly what he stated. Some of the older C-class headlights had really bad connectors from the bulb assembly to the headlight assembly, so they connect wires directly to the bulb assembly bypassing the headlamp assembly's connection all together. Not sure if I explained that 100% correct, but that's about the gist of it. Luckily, after the mechanic just bent the connectors back into place, only one of my turn signals needed this update.

Never had to change them....but I've changed out umpteen stop and rear light bulbs, headllights, and side markers. You have to laugh. The Germans spend all kinds of money on research and production to be able to let the driver know when a bulb is out and the Japanese just make it so the bulbs don't burn out. Duh.

A solution to the turn signal problem
I just wanted to add that I have a 2001 C320. Recently my front left turn signal stopped working and I got the warning message on the dash display. Interestingly enough, since then, the display always stayed on even when the car was turned off. I am thinking this is related to my recent battery drain problem if the car wasn't run for 24 hours+. Anyway, reading this thread, I was depressed that I would have to take the car to the dealership for such a small and seemingly inexpensive problem. So, I went out one last time to the car to check it. I was able to locate a small handle on the back side of the head lamp assembly that you can unscrew and easily pop out the turn signal lamp holder. I swapped left and right and then of course neither worked! So I took the bulbs out of each and slightly pried up the contact in the bottom of the holder and swapped the bulbs for good measure. Popped them back in the head lamp assembly and wa-la! Both were working again, and as an added bonus, the dash display does now go off when the car is off. I can only hope this solves my battery drain problem. Next option there seems to be the seat control modules based on what I have read. My other thought is the Tele-Aid/SOS feature which I dont use and seems to always emit a hum from the SOS button even when the car is off. Does anyone have experience disconnecting this so the hum (and consequently power draw) will stop??

There is an engineering change for the front turn lights. They add wires on both sides...I believe it's to give it a more positive ground as the socket assemblies have poor internal grounding. It causes intermittent (and solid) front turn signal problems. The hum is normal...there's a little fan in there that runs for a while after the car is turned off.

Thanks for the quick comment. Have you heard of the display staying lit all the time due to one particular fault and in turn, being a battery drain? I still have one fault, the SOS not being activated but the display goes off now. We'll see over the next week if my battery drain problem is gone also.
