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?

Cheers,

Michael.
