Bosch (Leaded Fuel) 4 wire oxygen sensor PB-11

["Paul" <paul@vb.co.za>]

hi guys

I see that the VW GOLF VR6 sold here in South Africa, has 
a Bosch 4-wire sensor marked something like PB11 instead of
LM11. This sensor is ok to use in leaded fuel, anyone know
how this sensor can withstand leaded, or any further info ??
