Rusty Fuel Filter

Bentley is known as a distinguished engine builder. However, there are cons to having Bentleys. Most modern Bentley models are prone to fuel injector problems. Bentleys that were manufactured from 2004 to 2008 are equipped with a fuel filter that can be easily corroded. Road salt can cause rust build-up in the outer surface of the filter. This can lead to leaks in the fuel housing. And if this is left unattended, your Bentley will lose fuel and you have a fire hazard.

The symptoms of a faulty filter are faster fuel consumption and fuel leak from the injector. To solve these hitches, find a more durable replacement from aftermarket manufacturers. Use our fuel filter replacement guide to easily replace the filter. Take note that you also need to adjust the retaining clip of this assembly.

Defective Wheel Bolts

Particular to the 2006 Bentley Arnage, there are factory defects on the road wheel fixing bolts. In selected units, some bolts are dimensionally incorrect. Defective bolts have the potential to loosen. If these bolts are not replaced, the wheel can detach from the hub, increasing the risk of accidents. Identify these defective bolts by performing an ocular check in the wheel assembly and look for bolts that appear to be insecurely screwed to the wheel hub. You need to replace these bolts with compatible units. For best results, contact your nearest Bentley dealership and try to obtain factory-made bolts. Replacing the bolts involves simple steps. First, you will need to gather the bolts, jack, and lug nut wrench. Next, park your car in a flat surface. Pick a wheel and find a solid chassis part where you can use the jack. Loosen the nuts by turning them counterclockwise using the lug nut wrench and then remove the hub cap. Finally, reinstall the cap with the replacement bolts. Refer to your Bentley owner's manual for more precise jacking instructions.

Problematic Hydraulic System and Braking System

Most Bentley models that were manufactured from 1997 to 2003 have problems in their hydraulic systems and brake systems. The main problematic parts are the brake houses and the hydraulic pipes. Aside from those, there are other common system issues. For Bentley limousines and sedans, the low-pressure brake fluid pipe between the master cylinder and the remote reservoir has a tendency to trap and retain air. This affects braking performance. In Bentley Arnages, the hydraulic hose that transfers fluid from the regulator has a tendency to leak. This will cause difficulty in steering. 1997 Bentley Azures have hydraulic system pipes that can chafe each other (specifically the pipes that connect the brake pump and the accumulators), causing fluid leaks. Different solutions are necessary for different problems. In the first problem, the hose and the brake fluid reservoir need to be replaced with better aftermarket units. The second scenario will require you to replace the hydraulic hose. For the third scenario, you only need to reposition the pipes so that they do not chafe against one another.
