After cleaning out the boost solinoid and fitting an K&N induction kit.I had filled up with optimax so a thought I would do an ECU reset, no fault codes just 1/2 sec engine light flashing. Finished reset took car back out for a run but would only boost to 0.5 bar I have checked all pipes wires all seem ok. Need help as Im going to Santa Pod on Sunday.

 

What did you use to clean the solenoid, you may have gummed it up. Make sure that the actuator is connected to the side port of the solenoid.
What MY car do you have as the solenoids are different according to MY.

 

Hi Bob my computer give up the gost so im on my mates it`s a MY99 car, i cleaned the solinoid with Wynn`s fuel injection intake cleaner. If this helps i removed the wires to MAF to fit the K&N, the car runs ok but just low on boost.
