European side, around Bahçelievler, master recommendation

My car is 2009 model. Especially when I pare it in a curved place, it gives an oil pressure warning. When I check the oil, I observe that there is no problem. Probably sensor malfunction. I also noticed white smoke coming from the exhaust. I am looking for a master, preferably near Bahçelievler, on the European side of Istanbul, in order to have both of them checked. Is there an affordable master you know that you can direct?

I wish everyone a good day.
