Got my codes today first was code:27 MOP open or short? Second was code:05 ks/ (LH) open or short. Can anyone help me out with the MOP ( Metering oil pump) one how can i sort it? Thanks all.

either the MOP is knackered or the wiring going to it is no good..your car is probably running in limp mode...i would check wiring and or replace pump...i have a pump if u need one...its not the easiest thing to change...you can run premix i guess...kal976@yahoo.com thanks

it forces a limp that will stop the boost and fun after a time out period forcing you to turn the car on and off

you have to replace the faulty EOMP unit ,, and sometimes replace the ECU or at least repair the burned tracks and replace the chip at the end of the ECU that is dedicated for the EOMP stepper controlling

however you may be lucky and find the motor hasn\'t poled out the ECU driver and instead you have errors in the feedback system
,, ie the full range TPS and the position sensor at the EOMP may be giving a faulty resistance via unit or its plug
( which you may be able to fix with contact cleaner )

it\'d be best to remove it and block it off to run premix, you don\'t want to leave a failed part in the oil system.
