Condition

This is a genuine BMW New Old Stock component that has never been installed.

Due to its age and long-term storage, the following may be present:

• Dirt, discolouration and wear to the original BMW box
• Ageing of the original packaging and labels
• Light storage marks on the metal housing
• Minor discolouration on the screws and spring
• Age-related changes to the gasket or internal sealing components

The valve has not been function-tested. Because this is an older carburettor component, the valve movement, spring, gasket and any internal diaphragm or sealing elements must be carefully checked before installation.

Supplied exactly as shown in the photographs.

Included

• One genuine BMW/Pierburg fuel-enrichment valve assembly
• One valve spring
• Two mounting screws
• Fitted sealing gasket shown in the photographs
• Original BMW cardboard box
• Components supplied exactly as photographed

No complete carburettor, additional gaskets, fuel hoses, adjustment tools or other carburettor components are included.

Installation recommendation

Before installation:

• Confirm that the vehicle has a Pierburg 2B-E / 2BE Ecotronic carburettor
• Compare BMW number 13111289911 and Pierburg number 4.07280.00
• Check the valve housing and mounting flange for damage
• Inspect the spring for corrosion, deformation or loss of tension
• Check all sealing and diaphragm components for cracks or hardening
• Clean the carburettor mating surface carefully
• Confirm the correct spring and valve orientation
• Install the screws evenly without overtightening
• Check the carburettor for fuel or vacuum leaks
