I have written before about DIY fixes for the SLK – mainly because there are people out there (and YouTube videos) that say its really difficult.

A few years ago (actually, it was 2010), my wife broke the nearside (passenger) indicator on the SLK. I have put off repairing it as I thought it was expensive and difficult.

This week it failed the MOT because the broken indicator was filling with algae and the LEDs were no longer orange. It appears that the orange colouring has worn off. As long as the indicators were orange, it didn’t matter that the lens was broken.

I bought the part from PFS Parts Ltd www.partsformercedes-benz.com. It was about £25.

Firstly, use the electric adjuster to move the mirror glass as far down and to the left as you can. This will expose a small gap between the top of the glass and the plastic surround. In the gap you will see a small wire clip. Remove it with a small flat-bladed screwdriver.

Next, lever the mirror glass out. It’s only clipped in. Scarey though…

Also, put something soft (softer than concrete anyway) on the ground just in case you drop any of the expensive plastic and glass bits.

Using a Torx 10 screwdriver, remove the six screws that hold everything together and remove the motor and the covers.

… and the front and rear plastic covers (no photo…sorry, got carried away and forgot – damned if I’m going to take it all apart again!)

Ten seconds to take out the old and put in the new indicator unit. It is clamped by the screws already noted and there are only two wires to connect.

Screw it all back together.

Job done.

£25 + 30 minutes.
