Hello guys,
i know this topic has been talked about a lot of times but I seem to have a rather special issue with this in my TT.
I've done all the things you may find on forums or internet to resolve this but still i get the warning light. So I'm
kinda desperate for another solution since this is quite irritating.
It's an 2000 year APX engine with 100000miles. First time I got the horrible red oil pressure warning I stopped the car and
towed it to the garage. Since car was not serviced properly with the past owners i wanted to replace every part that was related to oil pressure and do the full service on the car. On that service I've flushed the engine before doing anything else. Then i replaced all of these:
- Oil pump and the oil pickup tube
- Cleaned the sump
- Conrod bearings
- Turbo feed oil line
- Reconditioned the Turbocharger
- Oil pressure switch
- All PCV hoses (and i mean every last one) and replaced them with silicone replacements from Forge/Samco and similar
- PRV valve
- PCV Non-return valve on the T-junction
- Put in new Castrol Edge oil and filter
... the list goes on, but this is all regarding parts related possibly to oil pressure.
However with all those parts brand new I'm still getting the oil pressure warning light. It's driving me crazy... It only comes on at about 1500rpm when engine is hot (car is running at least 10min), but it never shows when car is cold. When rpms go 1800 or above the warning light goes away. It never shows on idiling if revs drop slowly so i don't know if that means anything. VCDS does not show any fault code in ECU. Engine runs smoothly with no weird noise whatsoever.
Does anybody have a suggestion what to look at to solve this ? Any other parts that could cause this ?
Could this be an electrical issue ? I've read a temperature sensor could cause it.... i did get an coolant red warning light a few times,but it never appeared again since then. Coolant is also new and level is up to specification in the tank.
Thanks
