Where to buy a Catalytic converter and rear silencer for 2006 Passat B6 1.6 Fsi? Have been having a few problems lately. Engine holding back. EGR light flashing etc when under high load. Replaced plugs and plug coils. Knew exhaust was dodgy though as had to be welded last time it went in. Recent symptoms worsening. Engine now at half power, EGR light on permanently, engine wont even rev out of gear above 4000 rpm. I am assuming it is in some sort of limp mode? Culminating last night with engine running on 3 cylinders (number 3 pot out - can't understand that one) loud banging noise from exhaust system. Feels like exhaust is blocked. This morning runs ok initially - all 4 pots working - but still lacking real power - exhaust is blowing quite loudly. I take the view that I should replace the exhaust first and then see what else is faulty. Seems a simple thing to replace the exhaust but no, the mechanic says I need the Catalytic Converter and the Back box. He says it's a dealer part only. If I get the parts he will fit them, but he won't supply. So I ring V-dub and they tell me the Cat alone is £748 + Vat. I didn't bother asking about the back box! It is possible the exhaust may be more than the value of the car at this rate! and there may be other issues to solve yet. I come away with the intention of sourcing the exhaust myself on the internet. But after 2 hours trawling I haven't found one. Does anyone know where I can get these parts, either new or a reasonable condition 2nd hand. Your assistance would be welcomed as always. I don't want to part with my much loved B6.
