It is also possible to note phisically this hammering noise, putting the hand over the oil filter cover.
All the cars produced from 01-06-2007 are affected.Untill a not defined period of production.The noise is generated from the forces of the internal cylinder combustion and the distribution system.
At the moment there still not exists a remedy.They still are studying a solution that could be retrofittable.The tests are under process.
IMPORTANT: this noise is only a defect affecting the passenger's CONFORT and in no ways has some conseguences on the engine life .
This happened to the car I drove at Nürburgring. When the car was good and warm we could hear a noticeable "knocking" sound. I thought it may had been because of the extended trashing these cars had been through; but obvoiusly it is a known phenomena. I hope they sort it out.
