Bods928

Hi all , I have a 1982 928s Euro model . I have no warning lights on my instrument cluster when I turn on the ignition . I'm thinking the silver Central warning box was at fault , checked it and found corrosion inside on the joints and where the wires connect the two valves. I have fixed the dodgy joints refitted it to the car but there has been no change , still no warning lights . I have a stop light but none of the others . I also have the flashing red light on the instrument and the exclamation mark is flashing in the centre console . The parking light comes on the instrument cluster when the lights are turned , I have no parking brake warning .

It doesn't cancel anything when I press the button on the dash . Could I have some advice please as to what I should check next . Much appreciated .
