Volkswagon Jetta Oil Pressure Q. I own a 1987 Volkswagon Jetta. Since I did an oil change all of the sudden the oil pressure warning light goes on as soon as the car gets warm. The oil level is okay. The oil I used was the one indicated in the manual. Please let me know if there is trend in this cars to do this and how much do you think I have to spend to fix it. Orlando

A. It's probably a bad Oil Pressure Sending Unit. This engine has two OPS's, a low pressure switch and a high pressure switch.

I would put a mechanical oil pressure tester on it just to make sure the actual oil pressure is within specification. If it is, I would replace both switches since they are cheap and easy to change. Just make sure when you change them you don't get them mixed up.

The 0.3 bar pressure switch is located on the oil filter flange and the 1.4 or 1.8 bar pressure switch is on the end of the cylinder head.

On 16-valve engines, both switches are located on the filter flange.
