Audi A4 B8 Engine Management Light

So driving into work this morning and the engine stuttered/juddered and the engine management light was flashing.

I’ve had this issue a few years ago and turned out to be a faulty coil pack, so hoping if it doesn’t sort itself out it’s the same again as it’s a relatively easy and cheap fix (hopefully)

Does anyone have any thoughts on the above? Guessing Audi’s go through coil packs for some reason??

I got a cheap Bluetooth code reader from amazon, might help you investigate your issue, as well as unlock some other functions before heading to the garage?

Ok so I ran a scan tonight and got the following code under engine 05646, I reset it (maybe I shouldn’t have?)
