Hi All,

Driving along as normal (30ish) 5 mins after a quick

blast down the dualer. Poxy engine management light comes

on. Parked up waited a min then switched off the car. Started

it - still on . I know it could be an endless list of reasons but

is there anythin' 03 WRX's are prone for (sensors etc) ???

P.S. Booked into Eden Subaru for next week.

Craig.

Had the same myself last week.

Parked up the Scoob & started it next morning,

All gone. Mine happened after a bit of a blast also.

try switching it on and off 4 times should clear it if not then its dealership time my05Sti did it and it all came down to bad fuel and a co2 sensor picking the fault up
