DB11 Problems After Spark Plug Replacement

[RAAM]

I agree regarding the spark plugs, but the dealer is simply following AM service guidelines (which I understand; that’s the best risk management approach). As to the fuel issue, AM sent the dealer some kind of diagnostic tool to assist in assessing the problem. So, this was AM’s recommendation in consultation with the dealer and based on the information they were able to glean from using the tool. This is way above my knowledge level, but to an earlier point, these cars are extremely complex (and becoming even more so) rolling computers that will continue to require extensive consultation between dealer and manufacturer for repairs.
