Most shops won't install parts supplied by a customer because they make money on the parts they sell to you.

An advantage of having a mechanic do the job is that the new parts come with a warranty (paid for by their markup).

If they install a part supplied by the dealer (with the MB logo on it), it comes with a full year warranty.

What this warranty means is that the dealer is obligated to replace the part for you for free. Even if you installed the part yourself or by an independent mechanic, it doesn't matter.

All MB parts, with star logo on it, come with a full year warranty.
