ok, 3 weeks
I've spoken to several dealers about it and they all told me that I had to make my claim directly to the Importer.
They apparently don't get paid enough for warranty work (aka the time being allowed and paid for warranty work is too low to do the actual work).
And honestly, I do not trust dealers. I've beem disapointed (and sometimes deceived) too often.
I've already replaced the bashplate myself.
