Hi,
Dealing with our first set back with a used 2011 CMS all4 - w/68K - we have put 15k on it in about 8 months and not had any issues.

Car entered Limp Mode last friday morning (yellow engine lights etc..) for no obvious reason. Read OBDII codes and they came back as Misfires in 1,3 and 4. Replaced plugs - no change. Have 1100-1800 psi in fuel rail.
Moved coil from 2 to 1 and vice-versa, misfire moved to 2 (and continued in 3 and 4). Going to replace coils - I live in rural Colorado so dealer/specialist is out of question presently.

Has anyone used any of the aftermarket coils, and do you have an opinion on them. Parts shops are limited in my area, so I am seeing BWD coils at O'Reilly's and Echlin, Delphi, Bosch and Altrom through NAPA.

Thanks and apologies if this has been discussed, but I did not find any specific information regarding replacement coil brands in previous threads.
