Hi everybody,

I purchased my C200 sports coupe exactly 2 years ago (September 2006) and 2 days ago I decided to go for my first Teflon + Polish at a mercedes benz authorized Valeting centre. I have to admit the guys did a great job on the exterior as well as on the interior of the car. They even cleaned the engine (somehow) and this is something I didn't know would happen initially.

However, on my way back home I noticed that my radio was unable to tune to any radio station! The other thing I noticed once I parked my car was that the central locking system was unable to receive a signal from the key from distances longer than 1-2 meters. While I could lock/unlock the car from distances even up to 50-60 meters sometimes more, now after the teflon/polish/engine cleaning procedure, I have to stand closer than 2 meters from the driver's side pointing the key to the driver's door in order to lock/unlock the car. I have tested this with both 2 keys. The batteries have been checked as well, and they are fine. Fully charged (3V).

It seems to me as an antenna wiring issue inside the engine. Perhaps somebody andsomehowunplugged a wire inside the engine! Perhaps. It is the only logical explanation to me provided theantenna receives radio signals from the radio stations as well as the key signal to lock/unlock the vehicle. Do you agree? Any ideas? Any thoughts? Any pictures showing something useful? Oh yes. There is noantenna mastmountedonthe rear glasswindow. It seems to be an in-glass antenna instead.

I have already booked for an inspection at the Mercedes Benz service centre for the 24th Sep. but untill then I still have 2 weeks to wait unless you guys help me here.

Thanks,

Sav

 

Hi, i have the same problem with my C180 sports coupe, it was very icy weather and i opened the boot and the next day when i went to open the car, both my keys woudnt work. i can open the door using the remote only if i stand really close to the drivers door, it doesnt work from a distance, also the radio is tuning properly either. Do u know where the antenna is located and can you please tell me how your problem was resolved. Thanks

 

I am currently having the same problems. I got my windows tinted and my alarm would not work. I went back to the tint place and removed the tint to see if it would work...still no luck. Now I am having to point the remote right next to the door handle to lock and unlock. This is truly annoying.

 

My c180 '03 coupe central locking with the key and radio are also not working, the windows are tinted if that makes any difference. What is the solution?

 

Anyone with any answers to this?????????
