BMW 8 Series Forum - Technical Talk on the BMW E31
Hi guys,
Have had sports 200 stainless cats on my 850 but still fails emissions.
I am working abroad and the car is at a local BMW specialist for the MOT, so I am at a slight disdvantage.
They say that the nearside exhaust is blocked???, and the L bank is firing ok.
Any thoughts of wisdom, this...
