my check engine light has just come on on my 2005 wrx when I was driving home and has stayed on, I've got the manual and it says I need to have my OBD system checked, any ideas ? All I've changed on the car is the back box, I've put a prodrive one on, but that's been on 3weeks without a problem any ideas or know where I've gone wrong ?

 

You need a code reader, cheap off eBay or borrow one. You can then read the code and reset it.

 

Unlikely the back box has caused anything.

 

So pretty easy then how do you use it ? Send me a link as where to find one ?

This is the same as I bought, works a treat.

Comes with instructions, easy to use.

Read the code, reset then report back here for advice!

 

or just pop to a specialist and get them to take a quick look,cant believe many would charge you much for reading a fault code

 

Perhaps give these guys a call and explain the situation.

Maybe they will very kindly pop out with a reader if you don't want to drive it there? :

I don't know anything about the garage, but just googled Cheltenham Subaru.

 

Rang them up they charge £93, bloke I work with is going to bring his kit in tomorrow, where do you plug the equipment in though ?

 

Yikes that's steep!

Your mates kit will plug into a socket near the pedals. It will only plug in one way, see this (page 2, 3rd pic down) :

Port is under the dash half way between the steering wheel and peddles.
