C180 Kompressor Indicator switch

[vijayvermajpr]

Hi all

it seems there is something wrong with indicator switch. It doesn't stay for long. It trips automatically i.e. without even steering movement. It happens only when i want to swith right indocator on.. left works fine

what could be the problem? can anyone suggest.

Probably need a new indicator switch. I had a similar problem and replaced mine. All fine now.

 

[vijayvermajpr]

i was trying to ask like is it a big work to replace it?
do i need to go to mercedes garage only becuase normal garage people said since steering have air bag we can't do it etc
and how much this work might cost?

My indie took and hour £55 and teh switch was £75. You need to remove airbag etc to get at it.

New W203 Haynes manual covers this task. Section 12.4. Disconnect battery, remove drivers side lower facia panel, remove steering wheel, remove airbag contact unit/clockspring. The rest depends on year of car.

Yes it is a steering wheel off job,has the car always been like it and is the steering level when driving straight ahead

Hi,

I've exactly the same problem now on my w203 '03 Coupe car...

I was trying to replace the switch myself today, but unfortunately I couldn't get the steering wheel off. I've successfully removed the air bag but could unscrew the allan 10 bold. It was too tight...
How to loosen this screw? (direction, method, etc?)

I would appreciate any help.

Double the length of your tool and you double the force applied to the nut for the same amount of effort, a hollow metal bar that fits over your wrench would be ideal.

Example;

How about direction?

How to loosen this screw?

Describe what tools you are using.

Hi Dec,

thank you for all your replies.

I'm using 3/8 flexi breaker bar with Allan 10 socket + extension (another 30-40cm) pipe.

I'll try to remove the steering wheel again tomorrow, but I'm not sure how to unscrew that bold. Is this a normal thread? Which way should I be trying... clockwise or counterclockwise to unscrew it?


Thanks for your help.

Counter–clockwise I should think, never taken one off before.
If you look at the seventh picture down in the link you will see the length of his tool, what I’m getting at is that if you extend the length of your ratchet you can increase the force on the nut, a vacuum cleaner metal pipe over the ratchet bar for example would do the job if it is made of fairly strong metal.

Take note of what he says in the article, turn the steering wheel all the way to the left instead of putting pressure on the steering wheel lock.

Example, see… http://202tech.mkosonen.com/howto/steering.html


Quote,
“Step 5: Now that the scary part is out of the way, Take a look at the big bolt that holds the steering wheel on. Removing it will require a big breaker bar, and two people. The bolt is a 10mm Allen driver. I used a 4 inch extension on my ratchet, and use a large torque wrench to take it off. It is necessary to have two people because one person needs to turn the wrench, and the other needs to hold the steering wheel in place. It is NOT recommended to torque on the steering wheel lock as that would likely break it. Have the other person hold the wheel in place.”
