The factory-fitted plastic dipstick guide sits right next to the W12 engine—a powerhouse that generates intense heat. Unfortunately, plastic isn’t ideal in such a demanding environment. Over time, repeated heating and cooling cycles cause the plastic to weaken, become brittle, and eventually break.
To make matters worse, Bentley doesn’t sell the dipstick guide as a standalone part. Instead, you’re forced to purchase the complete dipstick assembly at £129.99 plus VAT. Replacing the assembly also involves significant labour costs, as anyone who has worked on a modern Bentley will know.
We’ve engineered a precision-made brass replacement that eliminates these issues. Unlike plastic, brass won’t degrade with heat and time, ensuring long-term durability. It also secures the dipstick more firmly, allowing you to replace just the guide without needing a full dipstick assembly.
Installation couldn’t be easier: remove the old plastic guide and replace it with the brass version. No specialist tools or advanced technical knowledge required—just a quick, reliable upgrade that saves both time and money.
