Hi i have a 2003 roadster & it went for it's MOT last week & pasted but after about 20mins of driving her the TRC Off, VSC & Engine light came on. Took it back to the garage & they said that the only problem that registered was an O2 sensor, they cleared it drove it about & it didn't come on. I drove it home & yes they all came back on again.
Back at the garage they said that i need new Lambda sensors & if that doesn't work then it could be the CAT. My car was fine until it had it's MOT.
Has anyone else had this problem or has any advice about what it could be, they quoted £80 each for the sensors aswell.

Thank you

Em
