Withy Posted February 14, 2019 Author Report Share Posted February 14, 2019 1 hour ago, Greenman said: That’s not how VTS works. It shouldn’t prevent starting. You carry the fob with you (if you have the tracker activated). If the car is started without fob been present then tracker calls central control centre who contact you to tell you can is being driven without fob, they then track car to tell you/police where it is. There should be nothing that prevents the car being started that I am aware of. Thanks @Greenman i’ll give the Indy a call in the morning and get the latest. They did say they weren’t done troubleshooting It does seem odd that both fobs are in the car, and it hasn’t been activated /subscribed to anyway.

Withy Posted February 18, 2019 Author Report Share Posted February 18, 2019 Got the car back today after having the rather pricey VTS control until replaced. Was great to be back in the car (if a bit nervous since it's had some electronic work done). Anyway, stopped in at the shops on the way home, came out with a bag of shopping, put it in the boot, started the car, it fired into life, and then died. Now it's doing the same as it did as it was last week. all electrics are OK but a pathetic attempt to turn over if the key is turned quickly, but if ignition turned, paused then started it does nothing at all. Indy has been good, came out to where I was, gave me a lift home, and is now waiting at the car for his recovery guy to take it back to the garage. They have it for a few days as I'm away. Disappointed for sure.. but just want it back and working preferably without me being nervous about it doing the same again. 😧 Link to comment Share on other sites More sharing options...
Greenman Posted February 18, 2019 Report Share Posted February 18, 2019 What rationale did they use for justifying that the VTS was the issue? There is no where in any documentation that I have seen that might suggest the VTS has any relationship with the immobiliser or might somehow prevent the car starting.

It was the only error which was shown, and replacing it did indeed seem to resolve the issue if temporarily.. Bearing in mind what has happened tonight I'll be requesting that they just revert to the original, and refund me £666 of the total bill. I'd hate to think that my car was blowing this module though.. that would be very uncool. Won't know anything else until they plug it back into diags tomorrow Link to comment Share on other sites More sharing options...
Greenman Posted February 18, 2019 Report Share Posted February 18, 2019 Right, so understandable I guess. So maybe you have got an issue with VTS but it’s not that that’s causing the starting issue. That’s the problem nowerdays it’s just following the ECU error codes without any real other diagnosis. Link to comment Share on other sites More sharing options...

Withy Posted February 19, 2019 Author Report Share Posted February 19, 2019 There are some reports of similar issues https://www.pistonheads.com/gassing/topic.asp?h=0&f=231&t=1740679 https://www.pistonheads.com/gassing/topic.asp?h=0&f=231&t=1428976 i’ll reply to those to see if there was any more info I also dug out the VTS documentation from the paperwork that came with the car and called the control centre. Car hasn’t been active on a subscription for some time, so it’s nothing that they’ve triggered remotely. Good to rule that out. (There is a note in the VTS documentation which says : The Security Operating Center (SOC) can prevent the engine from starting if the vehicle has been stolen Although this is from a Macan VTS manual http://www.porscheownersmanuals.com/2017-macan/14/231-37032/PVTS-Porsche-Vehicle-Tracking-System-Operation-with-driver-card Link to comment Share on other sites More sharing options...
Skidd Posted February 19, 2019 Report Share Posted February 19, 2019 Agree with others, VTS feels like a complete red-herring. Good luck getting it sorted. Link to comment Share on other sites More sharing options...
fat haggis Posted February 19, 2019 Report Share Posted February 19, 2019 I hope you get it sorted in the most painless way mate. Keep us informed. I just noticed my fobs are in the docs folder and I keep that in the safe not the car 🚗? Link to comment Share on other sites More sharing options...

Yeh me too, I’ve never activated the tracker (there seemed no appreciable reduction in insurance premiums for doing so) and fobs are just tucked away in a drawer. It is worrying if a VTS fault can immobilise the car, though in Withys case the car does seem to turn over and splutter into life, would seem a strange way of going about immobilising it! Sounds more like fuel pump, coil packs or similar to me (but I’m no mechanic😉) Link to comment Share on other sites More sharing options...
topradio Posted February 19, 2019 Report Share Posted February 19, 2019 Slow turnover points towards a battery / motor / earthing issue. If it was an immobiliser of some kind it would either turn over normally but not start or just not turn over. You have changed the battery so that leaves the motor or wiring/earth. It started yesterday and then died - I would be checking all the earth straps on the engine. As others have said, its not the VTS. I should think the indi just read a fault code and replaced the one thing that it said there may have been some kind of fault with. Link to comment Share on other sites More sharing options...
topradio Posted February 19, 2019 Report Share Posted February 19, 2019 Can anybody point me at a wiring diagram for the 981, I only have one for a 987 and it differs quite a bit. Link to comment Share on other sites More sharing options...
Withy Posted February 19, 2019 Author Report Share Posted February 19, 2019 Spoke with the Indy today. Definitely is the VTS, and when he spoke to Porsche this is something they’ve seen a few times, they said that they also have a high number of replacement VTS units having further issues. Apparently there are 65 versions of the unit for 981/991 depending on age, model year, which way the wind is blowing etc... findings today have shown The new replacement VTS unit installed has also gone kaput, and they’ve tracked it down to some wiring loom issue feeding the VTS. I asked them to put in the old VTS just incase we could remove some of the ££ damage from my wallet , but it was reportedly completely dead. Porsche are replacing the (replacement) VTS foc, so the car will be sorted tomorrow. I’m away at the moment but will pick it up later in the week. i just hope that this is it sorted properly. Digging out the paperwork was also good to do last night as I realise the car needs an MOT (can’t you get electronic reminders of that nowadays??) appreciate all the advice and wishes to get sorted. I still love my 981! Link to comment Share on other sites More sharing options...

The car only turned over if you immediately went from ignition to start. if there was any delay between ignition and starting there was no engine movement at all Link to comment Share on other sites More sharing options...

Nobbie Posted February 19, 2019 Report Share Posted February 19, 2019 These are complex and expensive beasts when they go wrong🙁, think I'd better stick with a 986 on my budget. Hope they've nailed it now🙂 Link to comment Share on other sites More sharing options...

Withy Posted February 22, 2019 Author Report Share Posted February 22, 2019 Just picked the car up. I think I actually missed not having it! All working perfectly so far, and the Indy put it through MOT as that was due too, sailed through no advisories. Indy explained the setup/diagnosis/fault and I'm very very happy with the explanation and the service. I wouldn't hesitate to recommend Geo Morrison to anyone up this neck of the woods - they really know their stuff and customer service is exemplary. Roof down on way home as there was a sliver of sunshine, so @fat haggis I have that smile back already. Link to comment Share on other sites More sharing options...

Yeah sure is @Greenman So far I can't stop using the car whenever I can, and at the moment it's like an adventure if it'll start or not (just me being paranoid I hope for the moment)... reminds me of when I owned Alfa's !

Can this not be by passed so not to happen again & leave you stranded? Especially if not subscribed to the service anymore! In your case, it happened with 2 different VTS. Or, was something else the culprit that caused the 2 VTS fail? Link to comment Share on other sites More sharing options...

In hindsight this was probably drain holes, causing the vts unit to fry, and hence not start Link to comment Share on other sites More sharing options...
