Hey all!

Hey all new member here, first time poster too.

Have a slight issue and I'm hoping there will be many of you here that can shine some light on it.

Purchased a Mk5 GTi back in February absolutely love the car.
Recently though it's developed a intermittent issue with the oil pressure.

Basically when the engine temperature reaches 90 degrees the red oil pressure light comes on and beeps warning that I pressure is low and to stop the car.

I've only had it happen twice first one happened around a month ago and the other just yesterday.

Also I have noticed that the engine does take quite a long time to get up to 90 degrees too (possible thermostat stuck open maybe?)

On long journeys it's all fine the pressure issue tends to happen on shorter start stop trips around town?

Could this be a Oil Pressure Switch issue?
Or an oil pump issue? Anybody experienced this kind of problem before??

Also yes I have checked the oil levels and levels are all good car also had a full service a week before I purchased it, any information welcome.
Thanks in advance.

The oil light coming on will be the pick up pipe in the sump that is blocked and not letting oil up and needs looking as ASAP
The temp could be a thermostat not opening

Thanks for your reply Andy.

I did forget to mention in my original post that the sump was taken off and pick up pipe was cleaned a few days before I bought it had this proved by the previous owner.

I am confused as to why i do get the low pressure warning still

As for the thermostat, I have also noticed that my engine temp does fluctuate goes up to 70 then goes down again. Is this a definite thermostat issue?.

Should of replaced the pipe in the sump. Need to get the oil pressure tested
