hi everyone, I recently put Larini exhaust part for my XK, and yesterday I wanted to try the dynamic mode but unfortunately the error code appeared. the snow mode didn't work either. I haven't tried these 2 modes for almost 2 or 3 weeks after the installation so I just noticed this problem. the exhaust part was installed by one of my friends cause the 4S stores never replied to my inquiry.

anybody knows why and what to do? is it a serious problem if it can't be solved?

thanks

 

The 1st question is did they work before the exhaust change. if so then retrace the steps of the installation and check to see if wiring or mechanical damage was caused. My guess is something was damaged or disconnected which is causing the problem.
