VB Air Suspension 4C full air suspension with Autolevel for Mercedes-Benz V Class, Marco Polo, Horizon, Activity - incl. installation and ABE

The VB-FullAir 4C full air suspension compensates for changing loads and automatically levels your Mercedes-Benz when parked at a campsite. You benefit from a consistent driving height on the road and a level vehicle when camping, rather than a sagging rear end or a sloping bed.

Designed for your W447, with a clear AIRMATIC exclusion

This suspension is intended for Mercedes-Benz V-Class, Vito, Marco Polo, Marco Polo Horizon and Marco Polo Activity W447 vehicles built from 2014 onwards. It supports both rear-wheel drive and 4MATIC vehicles.

Not compatible with Mopf1 or Mopf2 facelift vehicles fitted with factory AIRMATIC. For these vehicles, 1sternehotel offers a separate module for manual, app-based ride-height adjustment.

Maintain the intended height as your load changes

The standard front and rear suspension is replaced by an electronically controlled full air suspension system. Sensors monitor the vehicle's ride height, while the VB-ASCU electronic control unit automatically checks and corrects it. The levelling system therefore accounts for additional loads such as a kitchen, rear pull-out storage, camping equipment or full water tanks.

A CAN bus interface connects the suspension to the vehicle electronics and supplies data, including vehicle speed, for its functions. The control system is compatible with the electronics and ESC system of the Vito and V-Class. Different software versions allow adaptation to the vehicle's intended use, and support can also be provided over the internet.

Level your parked vehicle at the touch of a button

Autolevel automatically levels the stationary vehicle both front to rear and side to side. Within the system's adjustment range, this can remove the need for levelling ramps. It benefits both the bed in the pop-up roof and the lower bed in the Marco Polo.

Choose between two ride-height versions

The suspension comes in Standard and +30 mm versions. In its normal position, the Standard version corresponds to the height of an unladen V-Class. The normal position of the +30 mm version is 30 mm higher.

The figures below are distances from the centre of the wheel hub to the lower edge of the wheel arch. They are not the vehicle's overall height.

Standard version:

+30 mm version:

Normal is the regular driving height. Sport provides a lower vehicle position, for example for motorway driving. Offroad raises the vehicle above its respective normal position and can be used up to 30 km/h. Above this speed, the suspension automatically returns to its normal position.

Make low entrances, ramps and tank draining easier to manage

Three additional settings support manoeuvring at no more than 5 km/h:

• Low-clearance mode: lowers the vehicle for low entrances and makes loading and unloading easier. Above 5 km/h, the system restores the normal driving height.
• Maximum, programmable level 1: set by 1sternehotel to the maximum height. This is higher than Offroad mode and can help when boarding ferries, for example.
• Drain, programmable level 2: raises the front and lowers the rear to help drain the water tank.

Installation and key system components are included

The package includes the suspension in your chosen version, installation, German general operating permit (ABE), Autolevel, emergency inflation valves under the bonnet and the CAN bus interface. The emergency valves allow the air suspension to be inflated from the engine compartment when needed. The spare wheel remains underneath the vehicle.

After installation, wheel alignment is carried out at a Mercedes-Benz workshop to check and adjust the suspension geometry. Wheel alignment, additional individual approvals, gross vehicle weight uprating and speedometer testing are outside the included scope. Individual approvals for other wheels or tyres and weight uprating can be carried out separately; these require an additional speedometer test.

Plan overall height and any weight uprating around your vehicle

Whether your Marco Polo remains below 2 m overall height must be checked on the actual vehicle, including with the +30 mm version. Wheel and tyre dimensions, tread depth and the selected ride height affect the result. Before entering a low car park, use the measured vehicle height rather than relying solely on the figure in the vehicle documents.

Suitable off-road/AT wheel and tyre sets can add up to a further 2.6 cm of vehicle height, depending on the combination. Together with a suitable Delta 4x4 off-road/AT wheel and tyre set, uprating to a gross vehicle weight of 3,450 kg is possible, subject to the vehicle's suitability. This is a separate modification, not an automatic part of the suspension installation.

Before choosing a version, measure the current distance from the wheel hub centre to the lower wheel arch edge at both axles. Comparing these measurements with the reference figures shows how your intended ride height differs from the vehicle's current position.
