I also had this same error with my 2015 TT cabrio about 2 months after delivery. My rear deployed fine but it was the front that did not inflate. Dealership replaced pneumatic pipes and seams to have fixed the problem.

 

There is a Porsche bulletin about the pipes. Apparently they can get kinked. This was the first thing the dealer tried on mine before replacing the compressor unit which turned out to be the fault.

 

thanks for your replies.
Porsche Colchester had my car for 3 days but could not replicate the fault.
I spoke to them a couple of hours ago and they suggested bringing the car back to me and for me to drive it until the fault recurred. They would then want me to drive it back with the fault showing. I agreed as i want my car back, although not overly happy. Spend well over £100k for a car and within a month been back to dealer twice and still broken. They called me an hour ago saying that on the way to my house the fault appeared so they've taken it back to try and fix. Getting quite frustrated now!!

 

Same problem here. Still under. Car still under maintenance.

 

sorry to hear that GR-NL. Porsche are driving my car back today. Apparently they have recalibrated the car with a software update. They believe this has cured the fault. I'll post again when I've had a chance to test it.

 

Problem solved.
(I also had a software update: did not solved the problem)
The problem was the airduct from the generator to the frontspoiler.
The airduct of the frontspoiler was pinched: therefore the frontspoiler could not blow up.

 

glad your all sorted now GR-NL. Mine also seems fine now. Happy motoring!

 

Thx Mike,
Same to you!

 

And dysfunctioning again....!

 

This is the same problem I had, same order of events and fixes which didn't fix anything, they should be looking at the compressor next.

 

Thanks Dragon RR,
The car is going to PC next Friday. I will tell them to look at the generator..!

 

My 991tS has the same continuos spoiler failure seconds into post 75mph and message does not relent until below 45. Dropped a dealer yesterday. Anyone report to NTSa? Also had an electrical smell after prolonged 120 plus travel. Anyone else?

 

My dealer exchanged the complete set: tubes generator etc.
No problem any more.

 

How long did the dealer have it?

 

Within two days. ( But I live inThe Netherlands).
Good Luck!
