Tiptronic change under warranty

Recommended Posts

Hi everyone,

I am approaching 80 Kmiles with my 2006 tip C4S and add enough of the high frequency noise that the car was making on the motorway at roughly 70 M/h, thanks to a Porsche official repair notice I found on the web, I learned they would replace the gearbox without creating issues if the car would have a warranty so I tried and I have a new gear box now, though the garage first tried to change the oil, sent oil samples to porsche and had to record a sound file of it...

another issue that I thought was related to the differential is not change though, when I travel at low speed (city) and I give gas and decelerate, I hear a "clunck" from the back, not loud, but all the time, the garage told me this is differential play and that 1 car out of 3 has that, but my differential is now new with the gearbox and I find hard to believe that this is normal, I was thinking of the rear Cardan shaft ( my central cardan has been replaced less than a year ago), but the garage say it is not possible, would you have any idea about it ? another garage said it could be engine mounts, but it would make the noise when I rev the engine on neutral

Warranty is really worth it, I realize that at 80Kmiles there are a lot of parts that get worn out on a sports car that would not normally wear, I hear this is normal on a 911, here is a list of what was done on my car this year

_IMS sealing ring (complete engine removal), I had a leak and negotiated this at purchase

_Front suspension (entire suspension with bearing...) I had a very bad "spooky house door" noise when I would turn the steering wheel

_Sway bar bushings and tie rods

_front coffin arms

_Central cardan shaft ( when they removed the engine the first time, they noticed the rubber part was porous and since porsche does not sell it separately they changed the whole shaft)

_new tiptronic ( again engine and tans removal)

My warranty is getting to an end, and I am going to take it again, though I think, there is not much that can go wrong now (the engine if I am lucky)

And despite all that and considering selling the car several times, I figured out that "there is no substitute " in the market, I guess one must deserve its cheaper 2nd hand 911, this might be part of the 911 learning curve, and changing for what, a M3 or M6, RS4, not the same fun
