Is it possible to reset the “air dryer service” dash message, on a V4 FH, without plugging a computer in to it?
Simple answer: No.
It’s a dealer only reset,and can only be done at the dealer, as the laptop need to “talk to Sweden”
A load of ■■■■■■■■, but it’s what it is, a pain in the backside.
Needs new cannisters, and exhaust, then a 5 minutes with laptop, to reset all limits. Mainly due to the cannister not being changed enough, £11 filter, leave it and it costs a lot more.
