| Answer:
Hi Pete - These cars have very specific faults, as the various functions are all carried out by different parts of the management. There is a temp sensor, linked to the hydraulic pressure actuator via the ECU. It sounds like that part of the system needs checking out, they frequently have wiring faults. The boost is controlled by the Amal valve as standard, but they are often modified. Bleed valves make the boost wander all over the place, so it's no surprise! A decent electronic controller might be a good plan, such as the E boost street, we sell them for £200 plus vat. |
