From what I can see when the CEL comes on it is EGT? I have had no hasstles for 15,000 with a cat back Magnex zorst, then today went to Manchester, filled up with Tesco 99RON for the first time ever and 70 miles later for the first time ever CEL came on but car was boosting fine - I think running rich because it was backfiring.
Please tell me what I should do. Peter

 

Find someone that can read your fault code. Whats your location ?

 

The 2006 STi hasnt got an EGT sensor.

All manner of things cause a CEL - get it checked out.

 

Thanks gents - I live in Derby - should I go to the dealer? Or who is recommended?

 

Not far to Scoobyclinic. They'll know what to do.

 

Thanks

 

Anyone with a scanguage or similar can plug into your serial port and read the code, then do a search on here for the description.

 

If I reset the ECU by disconnecting the battery and pressing the brake pedal to ensure all power is drined, will this cancel the CEL or is it captured in a memory?

 

Where is the Plug for the Code Reader to be found? Thanks Peter

 

On your steering column , just feel in front just below your knees.

 

wont work on a newage afaik

 

Plus it would be good to know why it came on

 

Thanks, Gents. This is all new to me - it has never happened before. The nearest place to me is the local Subaru dealer - is it worth asking them just to tell me what the code is?

 

You need to plug a reader to your car, the ECU will have stored the code for you. The reader will detect the code and will display it for you e.g. P0303 (Cylinder 3 Misfire Detected)

Look up the code here...

Scoobypedia | Trusted knowledge for everything Subaru | Knowledge / OBDII Trouble Code Definitions

then decide what to do and where to go.

 

Thanks verty much for being so patient with me....
