It's basically the "A" number, top right in your picture that is the MB part number. Get a matching one and you should be good. As a general rule, model specific parts have the platform number at the start, for example for a W213 E Class, the part numbers specific to that model will be A213xxxxxxx. For more generic parts such as parking sensors that are fitted to multiple vehicles, they will have a more generic prefix such as A002xxxxxx.

In your case, look for part A0295450632 on eBay etc. The fact it is A029 implies that the same part is used on multiple models so there should be plenty around.
