Gen 2 991 Turbo S - DAB problems

[Simond]

Hi,

If anyone can help here it would be surely appreciated.

The DAB choice sometimes falls off the Source menu even though my RS6 parked right next to it receives DAB fine and dandy. I did comparative tests literally side by side so that the RF signal to both cars was similar. Ok, the 200 Mhz DAB signals are subject to fade and vagaries but I reckon the tests I did are showing up a problem in the Porsche that's not happening in the Audi...

The Source options in the Porsche are sometimes only FM, AM and TV. No DAB. The Radio push button shows DAB stations and when I punched in DAB Capital the speakers were sounding out the Archers from radio 4. If I leave the car for a while DAB comes back & all's well for a couple of weeks. The telling point is that my RS6 PE never fails to display and present DAB in the menu. In this respect RS6 is fine & the Turbo S isn't. Both cars are exactly one year old.

A SIM card error that showed up after an OPC update had to be cured by one of their techicians coming out to me and resetting it all.

Anyone else had this DAB weirdness?

Thanks,

Simon

I would say DAB reception seems a little erratic model to model. It's almost perfect in our current car, but was diabolical in a new 718 Cayman loan car we had recently over the same roads, on the same day and with the same level PCM - there were problems similar to those you describe. Presumably you've checked the tuning etc is correct?
I would certainly advise having the system checked out your PC. You have a flagship model there and everything needs to be working properly.

Hi Clive,

Thank you for your help. I have checked the tuning, or I think I have as well as possible.

It's going back to the PC. On a porsche assistance AA trailer. They can keep it for as long as they want. Yes it's the flagship model but niggling faults like this are real spoilers & frankly I'm right cheezed off with the thing.

Thanks,

Simon

Niggling certainly and something that needs sorting, but not anything that should knock the gilt off the gingerbread. []

If you have owned other supercars, you will know none is perfect. I'm aware of many paying infinitely more and inheriting far worse defects than you are suffering. Nobody buys a 911 (certainly not a Turbo 'S') for the quality of its sound system! []

Enjoy the immense qualities of this model, which in comparison to its competitors, far outweigh any minor inconveniences.
Regards,

Clive

Hi Clive,

Good points. Thanks.

Hi Simon

My wife had similar problems with terrible reception on her Land Rover Discovery when we bought it new just under 2 years ago. The dealer had the car sveral times, changed the side window with the aerial and did various other things on warranty to no avail. At each visit they told us the car was fixed, but it was not. I cant calculate the number of hours they must of spent trying to sort it out. They even blamed our dog crate for the interference.
We had fitted from new dash cams at the front and the back. The front was hard wired but the rear was powered from the "cigarette" lighter. In desperation I disconnected the rear dash cam and hey presto the interference stopped only to return when repowered. A friend had a similar problem on his VW Phaeton. We never told our local Land Rover our fix but they were aware of the dash am all the time!
Did you have a rear dash cam?

Mentioned the problem during a visit to my PC today and the general thinking was it happens when station search is carried out in a weak signal area and retuning when in a strong signal location, should resolve the problem.
No idea if this will work, but I pass it on for what it's worth. []

Hi all,

Update: My OPC exlplained they've carried out tests and they're fitting a new PCM to the car.

Obviously in warranty (1 year old) but it would have cost me circa £2K2 + VAT had it not have been.

Thanks Clive too for asking about this problem at your OPC. I thought it might have been a weak signal problem and that's why I parked next to my RS6 and did side by side comparisons with outcome = DAB RS6 OK, DAB 911 not ok. Those tests and the photos I took & submitted helped them to decide to order another PCM. Let's see. Thanks.

Hi Simon,
Thanks for the update. That's a good result if it resolves your problem. Maybe you could let us know how it all works out in due course.
It's all useful information for the benefit of other members.

Hi,

Update as promised but nothing startling: The new PCM has been fitted and so far i've not experienced those DAB problems.

Thanks,

Simon

I took collection of a 991.2 GTS this weekend and I have suffered DAB weirdness. But also I have noticed the PCM has a constant 'connecting to google earth message' too. DAB was set by the Porsche centre and all was fine. Until the day after. Then the DAB wouldn't work. It's there as an option it's just every channel has no signal. Then for no apparent reason I can make out, it comes back and works ok. If I think about it I think I stopped the car, took the key out and took some photos. Then it was ok when I got back in. Today in the morning no issues. Got in the car in the evening and the DAB won't work. I do not want to go down the road of having the Porsche guys keep it for days to attempt to diagnose something and argue the toss about this and that. I just want that fixed, the unbelievable rattles, buzzing and creaking interior sorted and the wobbling passenger seat addressed. I have been absent from Porsche for 9 years and the quality is disappointing so far. I hope this is a blip as I want to love this car.....

Try retuning and storing all the DAB programmes at your own location. Maybe different settings are required to those at the PC.
Can't suggest any magic cures for the loose seat, rattles or creaks, but your PC should be able to address these.
As regards quality, I'm pretty sure your new GTS will outperform any Porsche you were driving 9 years ago! []

Thanks for the suggestion on the DAB.....unfortunately I have set some of the channels in my own location and these dont work. There was an issue with loading the PCC on my car too, so maybe its all linked to a ghost in the machine. At the Dealer tomorrow so hopefully a solution beckons. Bet a software update sorts it. As for rattles...who knows!!

Thanks, Brin

Still suffering problems with my DAB. Car is back in at Porsche for the second time....for a software update as a precursor, if that fails to rectify it, a replacement unit. It appears that after parking the car for a couple of days, there are no DAB channels with any signal and this continues for the whole day (my others car's DABs work, so it's not related to location). Clearly with no DAB signals the unit searches to find FM but the signal on FM is variable and constantly cuts out. And then the DAB returns "as if nothing wrong".... usually after parking for a few minutes to go shopping,say. Sometimes when starting the car, if the DAB is working, the DAB station defaults to a radio station I have never listened to. It's like it "forgets"....

I bought the car at one year old and the car went through the 111 point checks.... it is frustrating to have owned the car for just a month and for a total of ten days the car has been back at the dealer (radio, rattles, buzzing, creaking noises). I cannot fault the support of Porsche Retail Group after sales - they have been great. And the loan cars have been like for like (some of their own rattles and buzzing!) so I haven't missed the fabled Porsche driving experience. I expect my car will be back with me during next week after a few tests and fingers crossed it won't need to go back into the garage until the regular service.....

Thought I'd be closing this topic off from my perspective.....but I can't quite. DAB is sorted but it is strongly suspected (by me) that the software updates made to the PCM unit have knocked out the telematics. Vodafone say the car is not being tracked as a result. I found this out almost by accident since I couldn't get the Porsche connect app to communicate with car so phoned Vodafone. OPC didn't check all functions operat normally? I guess in theory there is no collaboration with a DAB and Nav upgrade and the tracker? The car is going back to the OPC for the sixth time since I bought it 6 weeks ago....statistically so far, this is the 'worst car I have ever owned'.
