> I use (068 919 081 A) 0.9 bar for the high pressure side on the 2.1 only next to the water pump I found that the 1.4 bar was to high and I got some phone calls regarding false alarms from the dymamic warning system
on the low pressure the sender that goes between the push rod tubes on
both the 1.9 and the 2.1 I use (056 919 081 C) 0.3 bar
