2017 Clubby S All4 Spark Plugs??
 

Just picked up my Clubby S All4 w/ 33k miles on the clock. She had a slight shutter at idle so I took her in to have her scanned.(I scanned her myself which yieled no codes thrown) Turns out the plugs were fouled and she needed a software flash. Im curious if possibly the previous owner ran bad gas or maybe a bad lot of plugs ?? Seems way premature to have fouled plugs at 33k miles.

Just over 23K on the clock here and no issues yet. I have not heard of any issues related to plugs with our F54's. I am guessing crappy gas quality, maybe non-top tier gas (i.e.- less added detergents) or maybe even running lower octane, which also has less detergents.

20K on my Clubby no problems with fouled plugs at all. Just got it back from Service and they also did a flash that is the 2nd one they did on the car. I too would think maybe bad gas or the last owner run 87 octane or just drove it in stop/go traffic.
