My car is juddering alot at the moment and has loss of power. My mechanic suggested it could be the EGR Valve. Changed that no solution.
He has stripped the car and found out its the catalytic converter. He has quoted me £600 to fix the the issue. He said the catalytic converter would would cost £400. I told him i have seen cats go for about £100.
He has said as i have a Astra 2001 1.4 16 valve, vauxhall made a special one for that model as its part of the maniold. Is that true? Do that particular one cost that much as been looking around at they go for £100 on the net for a general Astra cat.
He has suggesed he can modify the cat and charge me £200. No idea what he will do. He also said it wont pass the MOT if he does.
What do you think he will do? and will it cause an issue for when driving? do you think it will go wrong again in a few months if i have this done
Any help appreciated
