Hi I replaced like for like, reason being, the pressure switch ranges are different between the brown, that is fitted, and the grey so opted for what came off incase there was a reason. Think the part number was 04L 919 081 B, got it from LLLparts I used a deep socket to do it from under the car, don't recall removing anything to get to it except the tray on the underside of the car, bit of a pain but do-able. Cheers Mathew

Thanks for the help gents i’ve changed the brown pressure switch earlier and seem to have sorted the issue as far as i can tell under the conditions i was experiencing it. Hopefully its sorted..

It was a parts company deutscheparts,

Thanks for the info, Tried to source the brown one which is fitted and was told from my VIN that it was a grey one?? So from the research I've tried to do the brown one that is fitted 04L919081B operating range is 2.3 - 3.0 bar and the grey one 03N919081 is 2.0 - 2.7 bar. I'm sure the car runs at 2 bar normally. I would prefer to install what came off the car, but does anyone know if the grey one is a revised or updated version? why are the ranges different? would the grey one not cause issues? any help appreciated

Sorry engine code is CUPA. Had a look and found a brown One with a red plug, black/green and brown wires. Must be that its close to the other and looks similar. Is there a way to test it, what would i be looking for? thanks

Hi Got a Skoda Octavia mk3 vrs estate 2015 when driving from cold up hill so under a bit of load the coil light flashes and it loses power, i can switch the engine off and back on and it clears until a couple minutes later it does it again until the car is warmed up. Once warm i put my foot down when the revs are around 3000, it does it again, straight into limp mode Had this fault stored in VCDS 5580 Oil pressure switch P164B 00 (101) malfunction Ive changed the pressure switch (the green one) but no difference, not sure if there is another switch somewhere, for higher pressure if that would work? any ideas appreciated
