This is a thread of “Mercedes W204 Steering wheel lock remove to repair DIY”. Big thanks to the contributor @dannyhoang9 from https://mbworld.org/forums/, shares good tips with us.

 

Here’s the story of his Mercedes W204 steering lock replacement:

 

Bought my car from the auction, run and start fine when I try to move it out of the parking so the tow truck can tow it to my shop.

 

No damaged to front end or steering wheel when at the site. After the tow truck tow it to my shop with the dolly, only tow rear wheel but not locking the steering wheel with seatbelt. The car will not start, no crank I can turn the car to all the way but no thing happen !

 

Jump start but still cant start ! Check the battery, still have good voltage

 

Steering wheel just locked, can’t move ?! Lock like something prevent the steering wheel so the key not working

 

I try to find the electronic steering lock but can’t see it because it was hide deep the back of the steering column.

 

As I know there no diy or instruction for the steering lock remove for now so I will take the picture and help people like me wont have to pay thousand $$$! In repair bill at the dealer.

 

The ESL ( electronic steering lock ) cost $500 , you will need the key $300 to sync, program new ESL to make it working with the key, EIS ( electronic ignition switch ) plus labor for remove,install and program for MB dealer !

 

my cost only $60 to shipped the whole steering column with Mercedes ESL EIS and key, $500 to repair with 1 year warranty to ESL

take me 15 minutes to remove and 25 minutes to put everything back.

 

You need 3 things :

W204 ESL EIS and car key to rebuilt, repair it DIY

 

The ESL is the one i wanna share with all: $9.9 only i paid for it, from http://www.obdexpress.co.uk/wholesale/esl-elv-steering-lock-motor-wheel-mb.html

cheap, good quality, and of course working or not is the most important! It did work on W204 as the vendor said, so i think it would also work ok on W207, W212, E series or C series, like C180, C200, E200, E260, E300, E350, GLK300, GLK350.
