SQ5 Injector Seals

[Lee - C]

Hi All - I have a 2015 SQ5 and the vehicle had a terrible rattle / knock when at idle and below 1400 revs (approx).

Anyway had a diagnosis at Audi and informed that it was injector seals.

These have been replaced at a hefty price (seals are pennies but labour it clean injectors is very expensive!).

I was informed by Audi that the vehicle will still have a rattle / knock for a short while post injector seal replacement. Is this correct or should the engine be absolutely fine from driving away?

It is 7 days now and although not as bad as was, it is still definitely there!

Any help appreciated.
