Hello Guys We own an old 2007 A4 (since2010) cabriolet. Recently the doors/windows have started ‘rattling’ when driving with the roof off (especially speed bumps or rough road) It’s getting on my nerves now. We really look after it service wise etc but our mechanic is good at servicing but ratttles etc……….really doesn’t want to know. Any thoughts please

Do the doors and boot lid latch reliably when the roof is off?

Any comment on the above response Paul? I know you have seen it.

Older cars have rattles because things are worm out or loose. It's time consuming to fix but there can be easy gains. Putting aside the likelihood window guides are worn out , start instead with checks. Wiggle everything you can from doors,hinges catches handles etc. You'll likely find one is loose. You have to be the investigator. Try also shining a torch into door interior with window fully down ... which may help you spot internal parts loose. I've often taken off a door's interior panels to find parts loose behind ..., spare bolts dropped inside doors and other rattle causes. Next is door alignment. If hinges are worn doors may have dropped and guides on bodywork may rub a lot. You may find a need to relocate guides. A trick to correct worn hinges allowing a small drop , is to loosen the bolts holding the bottom hinge to the body. Insert one cardboard shim between hinge and body and all the slack from wear may go. Its crude but works. Oil hinges and catches next. Finally the worn the fur/felt inside door guides may also be matted and gummed up. If you decide you may renew them anyway, you can take risks first. On a hot summers day a strong washing up liquid and water solution can be run down window edges to clean guides inside doors. Await 24 hours for all to dry out afterwards. Then a light clear silicon machine oil can be run into guides , just a little , and you may all then seems perfect.

I hope some ideas work. As always take your time.
