Good evening,

 

The ASV on my vRS (BLT engine) is making a high pitched buzz, even with the engine stopped and the key out of the ignition.

 

The code 19558 was on the ecu but the valve works and the engine stops as it should.  All fuses asscoiated with the engine are OK and the wiring also appears to be OK.

 

I have fitted a new ASV but the problem persists.

 

Any help would be appreciated.

vacuum block? or did they get rid of this on the blt?

Think the vacuum block went but the n75 valve is still present somewhere could still buzz.

It's definately the valve that is buzzing.
