I have new air bags in the front end also a new compressor and dryer.
When the car is off and just parked it will stay up and won't sink until I sit on the front bumper then the cars front end will sink down quite a bit. Is this normal? Of course one might say "don't sit on the bumper and problem solved", but I dont think this is normal. Any comments would be great. Thanks

Sounds like you have a leak around the air bag solenoids in the front of the car. This would not suprize me if you have just had the bags replaced and the solenoids were overlooked. Do the air suspension self diagnostic test and it should pinpoint the issue.
