Check Fuel Tank Filler Hose
(G-Class)

Campaign Desc. :
20P0792205

This is to notify you of a Service Campaign launch regarding the inspection and replacement of the fuel tank filler hose on 2,446 Model Year
("MY") 2019-2020 G-Class (463 platform) vehicles. Affected VINs will be flagged in VMI as "OPEN" on December 04, 2020.

Background
Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz vehicles, has determined that
on certain Model Year (“MY”) 2019-2020 G-Class vehicles (463 platform), the fuel tank filler hose
may not be fitted properly, causing small amounts of fuel to leak when refueling. In this case, the
vehicle may not meet emission requirements. Contact between potentially leaking fuel and hot
component parts (e.g. exhaust system) is not possible, so a fire hazard can be ruled out.
Nevertheless, the fuel tank filler hose should be inspected and replaced if necessary on the
affected vehicles.
MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will inspect and
replace (if necessary) the fuel tank filler hose on the affected vehicles. The estimated replacement
rate is < 1%. Parts should only be ordered in the event a replacement is required.
