No, this is not correct. My previous car was CS 04, i ve never had this problem. i advize you to take it to your local dealer for check. Before that check from stop if this happens in sport mode,econ etc.
I recommend PDK and chrono package to all new Porsche customers. I own a Boxster S 2009 and my previous car was a Cayenne Triptronic. (Totally different cars) I don’t accept magazines 0-60 times. They are just indicators not absolute figures. In the real world you will be surprised of performance variance, positive or negative. From my experience when you engage sport+ you can easily take the lead from fiberglass toys or 3.8 triptronic/manual beetles : )
After more than 6 months of annoying noise the problem is solved. My first advice is the following: Change Dealer. I have changed dealer, he kept the vehicle for 2 working days. The problem was not a ball joint or a sway bar after all. He made the following routine inspections 1. Re-installed all carpets, upholstery and covers from passenger cabin and engine compartment. 2. Re-installed both car seats. 3. Secured the plastic storage room/cover located behind the head of car seats. 4. Re- installed roof. 5. Secured exhaust heat shield. 6. Secured window and lock mechanisms. Although he couldn’t identify the primary cause of the noise, I am pretty determined that the synchronization of 2 or 3 causes of the list echoed in the rear wheel of the car. All labor covered under warrantee. The mechanic informed me that the Boxster is the noisiest car of the current Porsche production line and it needs periodic maintenance to prevent rattling.
I have arranged a new appointment (6th in a row) for the same reason in the same dealer. I hope I will have news within next week. I found some good trails on you tube for similar mechanical sounds searching keywords ‘‘ball joints’’ ‘‘sway bar’’ etc. they sound pretty much the same as my problem. Maybe this can help other forum members to identify annoying axel - suspension sounds I hope that this time the problem will find a solution otherwise I am obliged to contact Porsche North America and cc Germany.
Thank you for your reply. I have changed the fan under warrantee and the noise is still there. I am certain that this noise is not normal and I really don’t know if it troubles the majority of Boxster owners. Is there any chance that the problem is located in sway bar; ball joints etc. and cannot be detected with a bare eye? Since I have Porsche warranty I am considering to contact the factory in Germany and wait their reply. However I don’t think that they can do anything from their location.
I have a Boxster S 2009. It’s been a long time since I hear an annoying knocking – rattling sound, near the rear passenger seat between wheel and engine section when driving at low speeds over road bumps or unsmooth road terrain. It is like driving a cheap 10 year old car that is ready to fall apart. My local dealer (not the sharpest knife in the cabinet) has inspected the car with no success. It seems that mechanics nowadays lack intuition and are mere Service Manual readers. I have done everything; exhaust ckeck, sway bar check, roof inspection but without success. I will really appreciate if you can help me on this
