Thanks i took it for another spin and light didnt come on again false alarm im not sure but not to post to many threads im going to ask some more questions.
When the engine not switched on i get EDC light show with symbol for catalytic converter once ignition on it gone take it that fine? also driving tonight never had all this light business salesman said to put light setting to auto but i got flashed by car wonder if this correct setting to have.
Feeling a few misfires on car not sure if this is normal or what first proper decent car so ultra paranoid at moment if something wrong.
