Issue with Horn Sounding
 

My horn will honk intermittently when i turn the steering wheel. It never happens when I am driving straight. Has anyone ever experienced this issue?

Sounds like either something is loose or shorted in your steering wheel.

I something similar happen when driving my SL500 hard one evening. It took a turn quite hard, felt the tires slip, corrected the steering and then my stereo went really loud. Turns out my right hand was a little too far left and was pressing the "+" volume button on the steering wheel.

I'm having the same problem on my 2004 55 .. mostly when turning the wheel.. but also if I slam the bonnet down the horn goes off and stays on until I pull the horn pad back.. To drive I managed to jam some plastic pegs between the pad and steering wheel.

Its with the dealer now who's talking about replacing something but quoting around $1000 so not sure if that's a whole new steering wheel.

How did you fix yours?

Mine is off and on, and I havent had it looked at yet. I dont drive my SL everyday, so it hasnt drove me nuts yet. I hear its probably electrical, and would be around the $1000 mark.

Same thing just happened to my '04 SL. Mechanic said the right corner spring for the horn is broken and I need to replace the whole horn center unit (air bag also) that is on the steering wheel. He is able to find an after market unit and quoted $1,500 for replacement. Any comments?

Here are instructions on replacing the air bag

I searched for corner spring but all I found was clock spring... at any rate I would imagine once you have the steering wheel torn apart and the air bag out you should be able to see what the issue is.

Hope this helps :y

Mercedes offers a repair kit (4 springs and bushings) that is an update for R230 and 209 CLK air bags. I had to use one after installing a CLK Black Series steering wheel on my 2004 SL55 to stop the horn from intermittently sounding off. I believe you have to look it up on the Mercedes EPC for a CLK. I will try to find the part number and post it.

Same problem here CLK500 2004. Went to dealer. Steering wheel horn repair kit parts 180 plus 146 labor.

Horn Fixed
 

Luckily, my indy charged $230 in fixing the loose horn wires inside the steering unit.:zoom:

OK, I BELIEVE this is the repair kit to cure random horn actuation's

SL500 Horn problem
 

So my horn has started sounding every time I turn the wheel. Pulled the relay but want proper repair. Where can I get the repair kit?

You should be able to order the parts kit from any Mercedes dealer
