General Information: MISFUELING: Notes

WARNING: This page is about a different car, the 2015 Volkswagen Beetle, 2014 Volkswagen Beetle, and 2013 Volkswagen Beetle. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Misfueling can cause insufficient lubrication which can lead to irreversible damage to the high pressure components, especially the high pressure pump. Damage in the form of seizing and particle abrasion can be expected. These particles will cause further damage in the pressure control valve and the injectors. If not sure, test the fuel quality. Analyze the fuel using the Fuel Identification Unit VAS 6774. Refer to the Operating Instructions. This analysis device does not replace the analysis made by a laboratory for warranty claims.
