Yellow oil pressure light

[Snipes87]

Hi guys just need some advise here. I recently purchased a 2.0 tsi it had a "Service oil sensor now error". I replaced both blue and brown oil sensors next to the oil filter, then i had the sump removed and cleaned and replaced the oil pick up, put in new oil 5w30 as well as a new oil filter. After this I am now getting a yellow oil pressure light that pops up if I accelerate hard, the light flashes twice then switches of and a message pops up to say rpms limited ro 4000rpm. I wasn't getting this message or the oil pressure light before I changed sensors and the oil and sump service. Any idea what could be causing this?

Hi Snipes, I would think it’s an oil starvation issue if it’s coming on only when you accelerate hard. Was the oil pick up pipe exactly the same shape and dimensions as the old one?

We didn't measure it, though it looked the same and it was a perfect fit. Thanks for the pointer i will have the pick-up checked.
Do think the sensor in the sump could also maybe cause this as well? Wrong readings? As I did not change that sensor, we just cleaned it up when we cleaned the sump.
