Hi All.

CAA Engine 2.0 tdi 2012 T5 Transporter. Supposed to have done 66k - i doubt this mucho

Issue - Red oil pressure warning light coming in between 2500 3000 rpm.

The problem started after replaceing a blown turbo. The engine came too a halt and i thought it was dead.
Anyway off to my mechanics it goes..
We replace the turbo and after a while the smoke has gone clean. all happy.

Now we have a fault we didnt have prior too the turbo - oil pressure warning light -
We have since changed the pressure switch and also the oil pump,

Obviously we changed the filter and oil - and yes we do have the correct oil -

We are also aware that this could have been the reason for the turbo failure but cannot find a fault.
at this moment we are now looking att all the connections electrical as we have 3 x light on the dash -
Cold start relay light is constantly flashing - engine manegment light in yellow - oil pressure light in red at 2500 - 3000 rpm and the oil pressure buzzer bing ..


Any knowlage of this issue and / or fix is mucho welcome as i have spent hours trying to find any answer to find not much out there regarding this issue on this model...

You need to get to grips with the electrical issues and measure the oil pressure directly from the switch location before you can say whats going on.

A wear metal analysis on the oil may also help.
