So I got in the car this morning and set off, then when to use a little boost after a mile or so and there was no boost, was hesitating and the eml blinked for a while then went out, no EML since but no boost at all and hesitation up the rev range. cars a 2007 2.5 wrx.

 

read code and report back.

 

no boost at all or around .6 bar , boost solenoid ? but as above check for codes first

 

P0301 - Cylinder 1 misfire (pending)
P0244 - turbo wastegate solenoid "a" range performance

 

Clean boost solenoid wouldn't worry about misfire yet.

 

The solenoid is vitrually brand new. ive cleared the codes and the problem appears to have gone for now.

 

did the light flash 5 times ?

 

I cant be sure.
