I’m home. Around all week.When are you back in the country? Has it been an awesome trip? I think it might be pertinent to try do the scan and test then. I dunno if I should even be driving it
Trip was fantastic thanks mate.
Hmmm... Well, I have had @Bigsidavies plug his VCDS into the van and we've established the changeover valve is working. Hopefully this isn't a false positive. I'll have to wait and see.
Does anyone know if changing the sensors involves almost as much work as replacing the changeover valve? Am concerned I may have to take it back three times like others have. Maybe it's worth 'just' getting both sensors and the change over valve all done at the same time...
149ps CXHA here
I have a CXEB. I think the switches are the same part number for all engine variants.
I think the lower one is easy and the top one on mine behind the engine was a pita because all the stuff the cxeb has in the way that had to be removed.
You'll gain no benefit really by having the changeover valve done except the £150 for the part. I'm pretty sure that when it completed the VCDS test successfully it's all good. Mine failed the test immediately and said test aborted for safety reasons.
Go with the cheap pressure switches first. They were less than £30 each for genuine parts.
Fingers crossed its just the sensor. Valve replacement and labour for me was £260, after some back and forth the place I bought from has refunded this to me.

I’ve also got the p0164b fault on my 2018 t6 with 63k miles, I’ve had the sump off when I replaced the oil pump belt and stainer was clean at 60k miles had genuine oil + filter at that time. Following this thread I’ve replace the oil regulator valve with a genuine part but still have the coil light coming on when cold. Am I better to replace both switches? I don’t have vcds but do have other diagnostic machines I can use. Any help would be much appreciated. Thanks
Just to update my fault, I replaced both brown and green oil pressure switches, when I removed the brown one from the filter housing the little gauze on the switch was blocked with sludge. The problem seems to be gone now, so will do another. engine flush and another oil+filter change.
Hello,
what I would like to do is monitoring both oil switches in car scanner, but I don't find them there. As I can define a sensor myself but I have to know the pid as you see here for oil temperature (which is from this forum)
does anyone know how or where to get this pids (for temp this 22202F value) for the oil pressure switches?

Thanks for the info,For
2220a3, the response is just a byte.
with this pid I get three values in Car Scanner:
0: no pressure, (normally) engine off
1: low pressure
3: high pressure
I defined a sensor in car scanner mapping the value to 2 bar for low pressure and 4 bar for high pressure, that were the roundabout real values I measured with my gauge when I had the regulation valve problem.
If it goes to 0 a red background is shown.
engine off (or switch, oil pump not working properly):
engine running idle or with low load:
and with high refs and/or high load:
I have the impression that the pressure switches mostly depending from the load.
So for checking the high pressure working well I defined another sensor which results to a value of 1 if load is over 85% and oil pressure has not switched to high (value = 3), otherwise 0.
then I can use this sensor to visualize a red background warning (that is the black P Öl Last, here with value 0)

Witam. Silnik CXHA 150. Jak prawidłowo sprawdzić ciśnienie oleju za pomocą manometru? Wyjąłem czujnik z podstawy filtra oleju i podłączyłem tam manometr. Silnik ma 70 stopni Celsjusza, na manometrach prawie 90 stopni.
Bezczynność (~70 VCDS °C) → 1 bar
• 1500 obr./min → 2 bary
• 2000 obr./min → 2,2 bara
• 2500 obr./min → 2,6 bara
Jakie powinny być wyniki?
Przyczyną tych odczytów jest to, że po jeździe z dużą prędkością, około 150 km/h, a następnie zwolnieniu do, powiedzmy, 40 km/h, kontrolka ciśnienia oleju miga. Po wyłączeniu silnika lub dodaniu gazu, ciśnienie oleju znika.

Witam ponownie, w moim teście okazało się, że czujnik wysokiego ciśnienia oleju i czujnik niskiego ciśnienia oleju otwierają się jednocześnie na biegu jałowym
