Ha Alex, thatís very funny too. Our controllers must not work the same. Ok, arrows up and down, yes. I just canít get it to switch to the front axle. Tried the three second press and a long press, hitting the up arrow if down was selected, nothing seems to get it out of the rear axle selection.

Silly question: Have you looked underneath to confirm that there is air suspension on the front too, and not just on the rear?

HAWK - Because the VB Air on a Sprinter chassis is only on the rear axle and not the front - unless again if you have some sort of pre-production version. Pictures would really help us, it is hard helping you without the benefit of seeing what you are seeing. Even though VB Air calls it the VB Full Air 2C (for Commercial Vehicle, not the Motorhome version), it is only a 1-axle system for the rear. You can not raise/lower the front.

It is in your manual, if yours is incomplete, download the entire manual from the link I provided previous post (coz they seem to have multiple versions of printed vs. online manuals and some are abbreviated but others are wayyyy too detailed with installation instructions). You need to read it cover-to-cover to understand the finer details of how it works (even though it does it in Full Automatic mode).

I was starting to wonder if we might just have rear air ride.
I think that might be the answer. Iíll let you know.

Titus, would like to meet again, but can you or someone explain how to PM? Not sure if Iím limping along on my iPhone. Just donít know where to find the instructions on that also!

HAWK - Sorry to read you cut maiden trip short, but storm & hail, I don't like them either. If you end up having front air ride too, you would be the talk of the forum. Don't know anyone who has

To PM:
Click on member name.
On profile, go down to Send Message and click on it.
Choose 2nd option on drop down menu - "Send private message to <name>"

Sorry to hear you have iPhone - just kidding, can't help myself, spent 35 years on the competing side of Apple, so I take my my ill-timed & ill-advised jabs on every opportunity I get

Alex AVI, why does the controller have a front axle option then? I'm not arguing, just asking. Is there a bag closer to the front? As I have said multiple times, I'm just trying to figure this out without manuals. It just doesn't seem like my controller works like the literature I've seen out there. I'm just confused! It sure would be nice to level it out for that slight slope. Nothing pressing, just curious and stumped. I might check with Titus too when we get together if he'd happen to know.

I just can't get the short push/long push to get it off the rear axle option.

HAWK - Because that's how they designed the controller, to be usable for systems with both front&rear axle air bags and those that only have rear axle bags (i.e. every AI Sprinter that has VB Air). I did not design the system, so I can not answer the rationale behind having a front axle option on a unit that only has rear bags. You have to contact VBAir USA if you insist on having a logical answer.

I think my confusion is in reading someone posting they could level or the air ride system was capable of raising BOTH the front and rear independently by 3".

Misinformation it seems. I'm getting what you are saying. They use the same controller for different systems and applications. We're good. Thanks.

I think you have to have engine running, emergency brake engaged for the manual adjustments to work. Then it stays engaged when you turn engine off...thus remaining level. I had problems and went to Mercedes to check my brake. There is a wire that was disconnected that allowed the brake to communicate with the remote. I was told the AR has to know the brake engaged to manually engage. Otherwise, you've probably noticed that AR disengages when you park and get out...you hear the air release

MANSDERM161 - Yes, the emergency brake needs to be engaged (1-click is all that is needed) for manual adjustments. But engine does not have to be running, as long as ignition key is in ON position. There is a run-time-extension where the system can still be adjusting to desired level after ignition key is turned off (approx. 5 or 10 mins depending on configuration). Then it shuts off on it's own and remains at that level. Once ignition is turned back ON, and parking brake released, the system will automatically readjust to what VB calls "Ride Height" setting - it's the dynamic setting that takes into account weight, terrain, speed, etc. to automatically keep re-adjusting many times a second as you drive. It is a very smart system - no wonder it cost over $7,000. You couldn't pay me that much to manually do that on every trip

HAWK - it depends. If in context of a Sprinter based AI, yes it is misinformation. If in context of a different vehicle, then it may be accurate. Accurate information could be misinformation if applied in the wrong context.

I only trust published information for my specific vehicle.
