got a odd problem with my acd/ayc

2 weeks ago after starting the car all 3 lights appear(not everyday somethimes its fine)
and last week everytime i started the car after 2 seconds all 3 lights go on but if i let the car run on the turbo timer the lights go away(only tarmac is on and i can cycle through the other modes no problem).

and now its suddenly working properly and i can cycle through all the modes so its working(somethimes after stopping at a place and starting the car again the 3 lights go back on and go away when it running on the turbo timer)
anyone know what could cause this issue?

 

it is probably the pump loosing pressure due to corrosion.. When the ambient temps go up you will get 3 lights more often..

 

Definitely the pump acting up with temperature change. You can test it by holding the gas pedal down and turning the key to the on position. (Don't start it). The pump should activate and run for approximately 10sec. If it runs longer than 20sec then it's losing pressure.
