About Bentley
Bentley builds gloriously comfortable grand tourers with hand-stitched cabins and enough torque to tow a small country house. Under the walnut and leather sits a lot of VW Group electronics, which don't always take kindly to a car that's been left sitting for weeks.
AutoECU helps Bentley owners with spare and lost keys, key fob repairs, diagnostics, module replacement coding and retrofits, using the VAG know-how that underpins most modern Bentleys.

Bentley questions
Can you make a spare key for my Bentley Continental GT?
For many Continental GT and Flying Spur models, yes, as they share a lot of VW Group key technology. Newer cars vary, so we'll check your car first. Send AutoECU your registration.
My Bentley keeps going flat and throwing warning lights. What's wrong?
Bentleys carry lots of modules, and a weak battery or a module that won't go to sleep can cause drain and odd warnings. Diagnostics will pinpoint the cause. Get in touch with AutoECU and we'll help track it down.
Can a replacement module be coded to my Bentley?
In many cases, yes. Replacement modules usually need coding or adapting to the car before they work properly. Contact AutoECU with the details and we'll advise.
Need something done on your Bentley?
We'll fill in the make for you. Just add your reg and what's wrong.
