Question

I got the engine code P1327 on my 2003 BMW 745i, can I still drive the vehicle? Check engine light is on

Answer 1

if the engine is not knocking or low on oil and there are no driving issues you should be fine.

P1327 is for knock sensor 2 on bank 1 (the passenger side of the engine is bank 1) 

the intake manifold will have to come off to replace the knock sensor
