Wondering if anyone has a known good cam crank waveform for this Audi S4 Quattro 4.2L V8. The engine code is BHF. It has a cam crank correlation fault for Bank 2 and misfires on all cylinders for Bank 2 at idle. The engine smooths out at higher RPMs. I am fairly confident the chain is off but I would like to confirm with a waveform if I could. I am looking for a Pico file so I can compare them. Thank you in advance!

I dont have a known good. However if you have a WPS 500 you could go in cylinder on each bank and confirm that way by comparing compression and valve timing bank to bank. I do this often. Very effective. You can also do an RC test with amp clamp and a sync. Then with the firing order you can see a difference of compression between banks. Maybe you already know all this lol.

Thank you Chris! You are awesome, bounty headed your way. My chain is indeed off. Looks like both cams are off, not sure why it is only coding for bank 2.
