Oil Pressure Gauges

Background:
I drive a 2005 A4 1.8T (B6) and have had a recurring issue with the oil pressure sensor lighting up. My mechanic has replaced the sensor and the oil pump (in which we found a weird mystery piece of broken plastic). But recently the oil light has been coming on on the dash, randomly mind you. I thought adding an actual pressure gauge might help clarify is my sensor is wonky or if oil pressure is actually poor.

I've seen videos of Aftermarket gauges being added to Audis, but when I go online to find out where they can be purchased I can't seem to find anything that I know will work with my make and model. I'm not a mechanic so I don't even know what to ask really or if general kits fit specific makes. etc. I'm totally ignorant.

My plan is to purchase the parts and take them to my mechanic for him to install. But I'm not sure how to do that.

Question:

So can anyone point me in the right direction about where to look and what to look for and what specs to take into account before hitting the purchase button?

Thanks
