I recently took my car into the shop to get the fuel filter changed. Later that afternoon they informed me that I had to have a fuel regulator also. And charged me over $110.00 dollars for the filter and regulatory. I told them I wanted to parts they took off my car but when I got there to pick up my vehicle something didn't seems right. 1st. How much are these parts? 2nd. I haven't been able to find a fuel regulatory anywhere I have looked online regarding BMW's..
Please advise
