A8 Tire Pressure System
Can anyone tell me if the monitoring system is morereliable then a hand held gauge? I have two medium grade digital gauges and they both agree the system in my 2004's MMIis understatingby about 3lbs. I'd like to think the one in my car is more dependable but I just don't want to ware out my new Bliz's any sooner then I have to, ya'know?
sounds like a case of two against one, to me. me, I'd take teh on-board system as a thumbnail reading, and trust the handheld, if I had one to use.
