Audi Q7 recurring misfire issue despite new spark plugs and recent brake squeak after two shop visits on Audi Q7

Some Audi Q7 owners report experiencing recurring misfire issues, even after replacing spark plugs, which may be attributed to faulty ignition coils, spark plugs, or fuel injectors, particularly in the 2007 to 2011 models. These owners have noted instances of misfiring or the vehicle shuddering during idling or acceleration. Additionally, some Audi Q7 owners report persistent brake squeaking, which can continue despite multiple service visits and tends to worsen in colder temperatures. If these problems occur even after recent maintenance, it is advisable for owners to seek a thorough inspection by a qualified mechanic to identify the underlying causes.
