if you have a check engine light on then there should be a stored fault code and this will help point to the issue and solve the problem

to get an anti pollution message as well then this points to a fault to either the catalyst or the exhaust O2 sensors

to come out with you need a new wiring harness seems a bit strange as the 1st fix , but the price seems reasonable as the parts are about £800 and its a few days work to completely strip it out then replace the loom

I'd say its probably best to try another garage who can pull the code and work to that 1st
