Just had a new H&S exhaust system and TEK3 remap carried out on my 02 Sti-uk prodrive. Was planning on going to a rolling road meet in Norwich tomorrow that I signed up for a little while ago but the 'Emissions Control System' (?) light has come on.

Just rang scooby clinic who carried out the work and they said they'll have to take a look next week. Disappointed as I can't go to the meet now!

Anyone know what might be wrong? Heard it might be related to the downpipe for some reason?

Sorry to post in general, but I'm hoping that if someone knows what causes this I might still be able to go down tonight.

Cheers,

Michael.
