Bad news, just had my S70 in for service and asked that they check out my very loud! door clicks - interestingly - what a coincidence, when I was waiting for my service to be written up another customer came in with same complaint - customer had door welded was told it was a "design flaw" the weld didn't hold and I don't know what the final resolution is or cost - I believe the service tech said new bolt system was needed. Anyway, I was quoted $300 USD for the weld job but I appealed on "design flaw" - Keystone Motors in Doylestown, PA told me they would "contact their rep" - bottom line - 4 days has gone by and no one has followed up with me - I'll have to give them a call. I too tried the lube, etc. - lube won't fix the design flaw.
