I have a leak from the attessa system above the rear diff but i cant quite determine where its coming from. Previous forum posts suggest the pressure switch but mine looks more likely to be the accumulator(from the last image). Can the accumulator be removed and refitted
Easy swap off the car. A very big socket and a lot of extensions on the car. Most of them are busted after 30 years.
When they have lost pressure you will hear the ATTESA relay in the boot clicking every minute or more with the ignition on.
