engine check light on!
Driving home from work and the check light has come on.
Done a diagnostic and it's come up with code 45 - Pressure switch
Just googled it and found out it's caused by overboosting, probably because I put a decat downpipe on almost 2 weeks ago and it's surging.
It hasn't come up beforehand, probably because when the car hit around 5000RPM, it missfired. Now I changed the sparkplugs last Sunday it's been running fine again and tonight, had some woman in a vectra driving up my chuff so gave it some beans to pull away and it's been flashing on and off since.
Just as well that my brother now works with me and it's his turn to drive next week!
Best I keep it off boost until I can get it booked in for the remap

thats strange i didnt get any problems when i had it fitted mate
i keep getting the engine light come on with the bug too, but it keeps coming and going every couple of days
was told it might be detecting a non existant misfire by Paul @ Xtreme, still running fine so aint gonna worry.

It's a 6K mate
It's probably just boost spike mate due to the cold ambient temperature (though not hitting boost cut), nothing too serious

Unit would monitor this & in turn tell you the fault code

Best get it in for a check up then if i was you , must be throwing a cell light for some reson or other , get it plugged in , there must be a fault code showing somewhere

i havent had these issues and im not going into what i got fitted and havent. but check all your boost pipes around the turbo. and clean the boost solinoid. may just need cleaning or a fault connector.
i have an 08 boost solinoid fitted to a classic sti and i did have this light. turned out it was a loose connection on the solinoid. as your issue is related to pressure i would definately check this area first. pipes off and give them a clean with come carb cleaner or brake cleaner
