Configure a PIWIS diagnostic package for supported Porsche vehicles

This listing offers PT3G interface, PT4G interface, software-only and complete laptop configurations for supported Porsche diagnostic work. Available functions depend on the vehicle, software build, interface generation and account authorization. Porsche online credentials and server access are not included unless explicitly stated.

Compare the four available configurations

Shopify variant Included Before ordering
Complete set Configured laptop, selected PIWIS software and PT4G VCI Confirm laptop model, condition, software build and required Porsche coverage
PT4G VCI PT4G diagnostic interface only Requires compatible computer, software, cables and any necessary account access
PT3G VCI PT3G diagnostic interface only Confirm that the vehicle, software generation and intended task support PT3G
PIWIS 3 and 4 software SSD Software SSD only Requires compatible laptop, interface and any required authorization

Offline and online-authorized functions

Compatible offline configurations can support vehicle identification, fault reading and clearing, live data, selected tests, service functions and other software-dependent procedures. Coding, programming, component activation, security access, software downloads and protected functions can require a valid Porsche account, online connection and permissions.

Not included: Do not assume that a Porsche online account, PPN access, security credentials, server authorization or an ongoing manufacturer subscription is included with any package.

PT3G compared with PT4G

PT4G is the newer interface generation and is the starting point for compatible newer Porsche applications. PT3G can remain useful for supported earlier vehicles and software environments. Interface generation alone does not guarantee coverage: confirm the Porsche model, model year, software build and exact task before ordering.

Vehicle coverage

Coverage varies across Porsche platforms, model years, control units and software releases. Newer electric vehicles and protected functions can have additional hardware, software and authorization requirements. Send KKS the vehicle details and required procedure for confirmation.

Laptop, updates and support

The complete-set variant includes a configured laptop; interface-only and software-only variants do not. Confirm the laptop model and condition before dispatch. Software versions and update arrangements change over time, so the current build and any included update period should be confirmed on the order.

Information needed before purchase

  • Porsche model, model year and VIN where appropriate
  • The diagnostic, coding, programming or service task required
  • Whether you already own a compatible laptop or interface
  • Any Porsche online account or authorization available to your workshop
  • Your preferred package: PT3G, PT4G, software-only or complete set

Frequently asked questions

What is the difference between PT3G and PT4G?

PT4G is the newer interface generation. PT3G is intended for compatible earlier software and vehicle applications. Confirm the required interface for your exact Porsche and task.

Which option includes the laptop?

Only the complete-set variant includes a configured laptop. PT3G, PT4G and software-SSD variants require compatible equipment that you supply.

Is a Porsche online account included?

No. Manufacturer accounts, PPN access, security credentials and server authorization are not included unless the selected package explicitly states otherwise.

Can the package perform coding or programming?

Some supported procedures may be available offline, while others require valid online authorization. Availability depends on the vehicle, control unit, software and account permissions.

Will it support my Porsche model?

Coverage varies by model, year, platform, control unit and intended function. Contact KKS with the vehicle details and required task before ordering.

Still installing CarPlay Repaired NIT module works fine, still working out where to mount CarPlay module as the cables from the cluster are not that long that it gives me many options I’ll post with video again when completed Cheers Andy

Customer photo review of McLaren Carplay /Android Auto module

Installed the CarPlay module in my 675LT. Finally, the screen has its own use. I love using Spotify and Maps on the screen via CarPlay. Installation was easy and I was able to start using it right away. Very satisfied.

Customer photo review of McLaren MDS VCI - MTS 6531 Vehicle Communication Interface

I recently purchased the McLaren MDS VCI - MTS 6531 Vehicle Communication Interface, and I couldn't be happier with my decision. As a former McLaren Racing Technician, I needed a reliable and high-quality VCI for my MDS, and this product exceeded my expectations. It's a legit product, brand new from BOSCH, ensuring top-notch performance and reliability. What impressed me the most was the competitive price compared to other sellers. I did a lot of research before buying, and this was by far the best deal I could find. The interface works flawlessly, providing seamless communication with the vehicle. Thank you for offering such a fantastic product at an unbeatable price!

Customer photo review of McLaren Carplay CarPlay module

Just wanted to check back in here, the gps has been working flawlessly. That one day I had gps issues seems like an isolated glitch or maybe an iOS issue. Very happy with the unit. drove a couple hours today, everything worked flawlessly again, including gps. At this point, it seems clear to me that it’s worth $1200, given that there’s no loss of functionality and it either fully works, or very nearly fully works, and likely will improve.

Customer photo review of McLaren MDS Official Diagnostic Tool Kit - No Annual Fee, Lifetime Use, Free Updates

Just bought the McLaren Diagnostic System (MDS) from KKS and wanted to share my experience. So, a bit about me: I'm from Taiwan and I own a 720S. I love DIY stuff, so I needed an MDS. I saw KKS selling the McLaren MDS Official Diagnostic Tool Kit and reached out on WhatsApp. They replied quickly and were super smooth with the pre-sale service. But I was a bit worried it might be a scam since they’re a new account with 0 reviews. To be safe, I suggested meeting up in person to test the MDS. They were cool with it, so I made a small deposit and booked a same-day return flight to Hong Kong. KKS even offered to pick me up from the airport in their McLaren. When I got there, they let me test the MDS on their car, and it worked perfectly, reading all the data correctly. Back in Taiwan, I connected the MDS to my 720S and it also works fine. I'm still studying the MDS to learn how to use all the functions properly. 5 stars to KKS! They sell legit stuff and their service is top-notch. Highly recommend them!

Customer photo review of McLaren Carplay CarPlay module

I installed the CarPlay module in my 650S last weekend. The installation was straightforward, and the module works perfectly. It’s made my driving experience much more enjoyable and convenient. Highly recommend!

Dear KKS-Team, thank you for developing that Box for my McLaren 720 S. It is simply awesome, and works perfectly reliable. Easy to use easy to install itself by plugging in 3 cable to the car slots. Just plug it in and connect your phone, done. The only challenge is getting to the slots. Herefor you need to unmount the back wall of the interior., this is quite tricky for unexperienced DIY guys like me, but surely possible. And this is due to the car not to the box. It’s is a real upgrade for the car, because the standard IRIS system is, as owners know, not quite the best. The rest is clear you operate Apple CarPlay, which is the same as you know Thank you so much Thomas Besides that I’m writing from Germany, so please excuse misspelling…. It’s not my native language. 😉

KKS Carplay & Android Auto Module V2 Compatible with McLaren – For 650S, 720S, MP4-12C, 570S & More

Great unit, worked exactly as promised. Needed to recalibrate a power seat after replacing a faulty seat module and reset the airbag fault. The cost of having this work performed at the nearest dealership 200 miles away would probably exceeded the price of the MDS. Only reason I didn’t give it 5 stars is due to the lack of documentation. Fortunately it was easy enough to figure out what all the acronyms stand for and how to perform basic functions. Well done KKS.
