SERVICE INFORMATION

Symptom 404000 Fuel System Concerns

ISSUE

During extremely cold weather (below minus 15 degree Celsius/5degrees Fahrenheit) Diesel engines can experience difficulties with starting due to fuel supply issues to engine

CAUSE

Formation of wax crystals in diesel fuel can lead to blocked fuel filters and/or lines in markets where winterised diesel fuel is not used or readily available, or quality of such fuel may be inconsistent. Retailers and customers may seek to use third party fuel treatments.

ACTION

Jaguar Land Rover Engineering validated DFC Plus HP Extra Cold weather performance (BG Part no 23711) and DFC Plus HP Extra Cold weather performance with Cetane improver (BG Part no 23811) additive products from BG Products. Although effectiveness of these additives depends on the base fuel and environmental conditions, their anti-waxing performance and effect on the ability of vehicles to start at very low ambient temperatures have been validated to minus 23 degrees Celsius/minus 10 degrees Fahrenheit, based on the supplied samples and base fuel used. These products may help to reduce the concern over wax crystal formation detailed in this communication, but ultimately the manufacturer is responsible for the performance of their products. This communication is not intended to inhibit the use of alternative products of equivalent quality available in the market, but it must be noted that their effectiveness on vehicle Cold Start performance has not currently been validated.

APPLICATIONS

It is highly recommended for the additives to be applied at the pump just before the refuelling.
