mk4 golf oil pressure problems

[weetoogood]

Hi i have been getting the red oil pressure warning light flashing on my 1.4l 16v mk4 golf. It only started this week so i got a new oil filter and a can of flush to try and clear out anything that could have been blocking it. But as soon as the new oil was in i let it run through before starting it then later tried driving it. It runs but oil light still flashes after about 30 seconds of driving. Next thing i will be trying is a new pressure switch and cleaning the oil strainer out. If anyone else has had the same problem and has figured it out any help would be appreciated.

Could well be a pump or pressure problem.
