jetta oil pressure light

Hello,

I have a 95 VW Jett with 165,000 miles on it.
I recently had my oil changed and my oil sending unit a couple of months ago. My car had been running fine but just about 2 weeks ago my oil light would come on constantly after it warmed up to half way on the thermostat. I checked the oil and the oil level was fine. So, I took it in last week and had an oil change. I told him about the beeping and he said he would check on that. I picked it up later that afternoon and he stated that i needed to have my oil pump replaced. Is it a possiblity that my oil sending unit could have gone bad or needs to be adjusted. Just seems odd to me that this occurred a couple of months after I had the oil sending unit fixed.

Why was the sending unit replaced at first. Which sending unit was replaced? Did he put on a mechanical gauge?

I had the oil sending unit/switch replaced after an oil change because my car was loosing oil. It turned oit that the oil sending unit/switch was cracked and oil was gushing out. Every since that my oil light has been coming on but now it seems to come on more constantly. Especially in the afternoon traffic. I assume because the car is running a hotter at that time of the day. It comes on only when I slow down like when you go into curves or stop and go traffic. My mechanic stated I probably need to get the oil pump replaced. I was just wondering if its possible that the switch could have went bad. I was also wondering how I could check the oil pump myself. My mechanic said that the oil pressure is borderline right now but if I didn't have the oil pump replaced soon it could become a more serious problem.
