It's to your benefit and is much easier for members to see your car (YEAR SLK "MODEL" and nothing else) details in Vehicle Details

so the best method to update is:

click and follow the instructions FOUND HERE to update your profile.

If you have problems figuring out how to update your profile, just click

"REPORT" (3 buttons top right in this post)

and we'll help you out.

Once done, let us know and we can re-locate this thread to the proper area.

Still need the model (SLK200? SLK?? whatever)

Like this:

2002 SLK200
2002 SLK230

whatever you have. NOTHING else is needed, nothing else will help.

BAS/ESP light, speedometer and roof stopped working. I’ve been told that I need a A170 545 02 32 ESP Control Unit. Where can I get a replacement? Do these modules need to be coded to my car or are they plug and play?

You didn't change anything that I can see. OR if you did, did you remember to save the changes?

Hi,

I am looking for a replacement A1705450232 ESP Control Module for my R170 SLK (2002). Any ideas where I can get one and if it needs programming to my car?

Thank you

eBay and no it doesn't need coding but needs to be exact part number

Yay, replacing A1705450132 ABS pump and K40 relay finally fixed my ESP/BAS issues 🥳🙏🏽

I may need to make the same repair on my 2004 SLK320. Did you replace just the 170-545-01-32 module or the entire assembly including the ABS pump? If just the module, was it difficult to separate from the aluminum block once the four screws were removed?
