7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

Post O2 sensor delete

I have p0420 code so I bought the o2 simulator from magnum tuning to avoid pulling the engine to replace exhaust manifold and cats.. Anyway i keep getting o2 sensor slow response. This simulator fluctuates between 0- .95 volts. But I donít know enough about the proper behavior to know why itís pulling that code. Anybody have any suggestions?
