Hi,

my 53 plate impreza sti has stopped boosting fully at 4k.

Acceleration is very smooth, but just doesnt have the kick anymore.

Had it on a diagnostic, and it had the code for the boost solenoid.

I bought a 2nd hand one off Ebay, but pretty sure it's wrong part, as part number is different from what was on the car, and it has a blue sticker rather than an orange sticker (can anyone confirm correct part number and whether it's different between WRX and STI or classic / bug / blob?? )

Once I do get my hands on the correct one, will I need an ecu reset once fitting, before the car will run normal again? Im thinking if the car is in limp mode.

THanks!

 

no-one got any ideas here?

 

Try cleaning your boost solenoid valve with carb cleaner mine was only boosting to 0.5 bar not sure wheather that comes up on a diagnostic check or not.If you connect the two green terminal blocks under your steering wheel and turn on your ignition but don't start your car will go through a number of checks listen to the boost solenoid valve if it is clicking it maybe needs a clean if it doesn't click it's f##ked.Not sure if there is a difference mine is fitted with a 3 port boost solenoid valve
