Oil light keeps flashing

Are you hearing any ticking or knocking when the light is on? If not, then most likely the oil pressure is okay. You can check it with a mechanical gauge and check the oil sending switch. It may be bad.

Could be a faulty oil pressure switch. But yes, a clogged pickup
screen is common on the 1.8T engines, especially when the wrong
oil is used.

The good news is that removing the oil pan to check the screen is
quite easy.

If the oil pick-up is plugged, you would most likely hear ticking and knocking.

Not necessarily. Since the oil pressure warning switch system
checks for pressure at 2000rpm, you can have enough oil pressure
for a quite engine, but not enough to close the switch at 2000rpm.

I've seen this many times.

Restrictive screen should have been a better word for me to use.

My apologies to the Experts.

You have to check the actual oil pressure with a gauge then go from there. You could have a restricted oil pick up or bad oil pump. That is if the oil pressure is good.

You need to start a new question that includes your make model year engine size etc. That way other users can be helped looking for the same answer. Also answering another question on someone else's question is too confusing.

Do you hear any knocking from the engine when the lights come on?

These vehicles have problems with stock water pumps breaking.

Check the water pump for circulation.... a simple quick check:

If that is OK, you need to check the thermostat to make sure that it is opening. Find the lower radiator hose and check
how hot it is compared to the top hose. If it NEVER gets hot, then the thermostat is not opening or the water pump is not
pushing fluid.

If it DOES get hot, but the fans don't come on, you need to check the fans. However, fans are not required when driving
at a constant speed... so if it overheats while driving at steady speeds, then it is not a fan issue.

The oil light issue might be related to the overheating... oil gets thinner when it gets hot, so it does not produce the same
pressure.

1.8T engine or 2.0L engine? If 1.8T, you could also have a restriction in the oil pick-up screen in the oil pan.

Blue temp light. My bad, sorry!

Ignore the above post.

In my defense. I don't screw-up often! :-)

Hi there,

I would have both sensors tested, and get the oil pressure tested with a master gauge, this will give a true indication as to the engine oil pressure.
