Scotty, my wife has a 2011 Jetta. The car stared hesitating and I check the error code and it said cylinder 4 was misfiring. I replaced the plug and coil on cylinder 4 and everything was great. 3 weeks later same issue. What could be wrong?
only use oem factory coils on those, chinese made ones are junk. if not that, wiring or main computer may be damaged too
