Wing Mirror Turn Signal Lens (R231)
I have a 2014 SL400 (R231) and I have recently noticed a crack in the turn signal repeater light in the left hand wing mirror. I would like to replace the lens / light unit / door mirror shell - the smallest of those options that I am able to buy...
So, does anybody know the part numbers for any of these? I am having difficulty tracking it down.
Thanks in advance!

Replying to my own note, after a bit more research it turns out the smallest part sold is the entire mirror shell - MB part number A1978100164, and paint code 9197....
I can't seem to find one for sale here in the UK right now though.

Google the American version of your question, "sl400 side mirror turn signal replacement". You can replace just the turn signal lens.
Here's a video that will get you close to what you need to do.

Thanks,
That's all do-able for me, so now I just need to find the right turn signal insert. There seem to a lot of variants that al look identical - or maybe it's just the same insert used across multiple Mercedes models with different part numbers.
Google and eBay to the rescue....

You may want to try part number 1978100379 (R) or 1978100279 (L). Or check with your local MB dealership.
