MMI update or not
And yes, bad coil of course means misfire, which can shake. But in practice, if yours cleared up post pump change, would be hard to prove. Still, you could turn it in on the claimed prior repairs and see what happens.
Separately my 2000 A6 4.2 got the same advance recall letter, but it hasn't been called in yet.
Has anybody received a Service Action letter from Audi regarding the ignition coils? I can't renew my registration before such inspection/replacement. Could that have anything to do with my previous thread about rough idle/engine stall which led to replacement of both fuel pumps?
Thanks
