Hi Andy. Sorry I can’t help with the location of switches. Nor would I know if the filter has caused the problem. I’m not that mechanically minded. Mine is due for a service in October so will hopefully investigate more then. Mine hasn’t even come up with a code yet but the light is starting to come on more frequently. Please keep us postedHi, watching this one with interest as my 2019 T28 has just started displaying the same fault. Same P164B00 code and symptoms. Mine started 2 weeks after an oil and filter change and its first 300+ mile long run towing in a year. I potentially made the mistake of fitting a cheapy GSF brand oil filter but I did use the reccommened Castrol oil.
Does anyone know if you have to drop the oil to remove the oil filter or can you take the filter it out for inspection without? Also any heads up on where the two oil sensors are located? - Thanks!!
Information should be in here:where the two oil sensors are located?
UPDATE
Eventually ended up in VW for this issue as nowhere managed to fix it, I had an engine mount broken and a damaged wire, this they thought fixed it, then it came back again, they checked the oil pressure switches again which were new, they then thought one of the switches was faulty, this worked, BUT ONLY FOR TWO MONTHS, then back to flashing coil light and loss of power, they now think the sump is gunked up and causing the oil pressure switch to stop working and causing the issue to return.
They now want to do an engine flush , take the sump off etc!!
So since about October last year I still have the issue, I hope this helps others if you have this problem!!
I’ll update again when it goes back in , in a couple of weeks!
Hi P1les have you had an update with this issue? I have the same faults. Coincidentally I have had the issues since having my front engine mount replaced so hopefully it’s an issue with a damaged wire.UPDATE

Mine hasn’t done it in a while, had my checked with a diagnostic machine. Had a few errors but nothing major. Cleared them all and now seems fine. Drives perfect, just letting it fully warm up before I think about giving it some. But I drive like a granny so fingers crossed will be fine. Hope the issue has been sorted for yourself.So I have had the exact same issue, 2018 T6. Glowplug light comes on when engine cold above 2500rpm, turn off and on when warm it disappears. First garage replaced the oil pressure switch, that fixed it for 1 month then back on. Went to another specialist who diagnosed it to the oil pressure regulation valve. They said this valve closes a bit when warm but had jammed in position. He said this part had been superseded by VW, perhaps as they were a known fault. Reading this forum it seems like its around that age vehicle that gets the problem. They unfortunately fitted a faulty valve, and red oil light came on after 5 minutes of driving, returned to the garage and they rectified with a new part. All seems to be working fine again now, but only 1 week in. Will report again in 2 months. Thanks to Vee W services in Bristol for great customer service and professionalism in fixing this
Hi,How we getting on another week later?
Collected my 2017 T6 T32 yesterday and it has the flashing coil. Read this thread with interest, particularly as mine also seemingly has a ‘stop/start’ fault. I assumed this was due to battery charge level as the van was stood for 6 months but perhaps they’re linked
Check the wiring on top of the engine, I had the same issue and found that a wire going to a sensor on a water pipe had worn away, I fixed it and haven't had an issue sinceHow we getting on another week later?
