Engine yellow warning was intermittent now permanent, no problem with the engine, car is regularly serviced and performs well. Also, when on cruise control car jerks for 15-39 minutes, also intermittent. Switched off cruise control, no problem. ABS, ECS also intermittent faults, now permanent on dashboard. Car mechanically is OK, use it every day from Arbroath to Aberdeen for work. Is there a main control card that may be faulty and creates all these electrical faults. Just an insight before I go to a sparky. Thanks
