...to the oil level/temp sensor, (see here U1019 Oil sensor location help! ) fixed that and U1019 went away. But now, after a 8 week absence P164B is back when the engine is cold.
So odd, P164B was a daily occurrence with a cold engine until U1019 appeared, then once U1019 was fixed P164B is...

So I’m a year on now with this issue (p164b flashing coil light when cold , loss of power)
After 4 different garages including VW main stealer, all the oil pressure switches and regulator being changed twice, the problem still kept...
