Active Diff Code Out (GHAS) for BMW F / G Series
Swapped your Active M Differential for a mechanical LSD? The car still expects the factory diff and fills the dash with faults. We code out the GHAS module so it runs clean on your new diff. Done remotely, about 20 minutes.
✅ Codes out the factory active rear diff (GHAS / GSD)
✅ Built for mechanical LSD swaps like Drexler or OS Giken
✅ Clears diff faults and dash warnings
✅ F and G Series cars with an electronic rear diff
✅ Reversible if you refit the factory diff

FAQ
What’s GHAS? It’s BMW’s electronically controlled rear diff, sold as the Active M Differential on M cars. A motor locks it up based on what the car is doing.
Why code it out? A mechanical LSD has no motor or sensors, so the car thinks the diff has failed. Coding it out stops the faults.
Can I go back? Yes. If you refit the factory diff, message us and we’ll code it back in.
Will it affect my tune? No. Engine software isn’t touched.
Will a dealer update undo it? A dealer software update can reset it. Let us know and we’ll sort it.
Pick a time for your technician session, then you'll go straight to checkout to lock it in.

LOYAL BMW ENTHUSIASTS
Had the NBT EVO ID4 to ID6 upgrade done on my 2016 M4 and the difference is huge. The new iDrive interface looks much more modern and having full-screen Apple CarPlay makes the interior feel years newer. Process was smooth and everything worked perfectly.
My X1 came with the newer EntryNav2 system but didn't have Apple CarPlay activated from factory. Bimmer Drive enabled it remotely and now CarPlay works wirelessly exactly like OEM. Very easy process just connected the ENET cable and they handled the rest.
My G30 5 Series already had factory Apple CarPlay but it was stuck in the smaller split-screen layout. The fullscreen activation made such a big difference. Looks cleaner and uses the whole display like newer BMWs. No aftermarket hardware needed.
I was looking at aftermarket CarPlay screens for my F30 but decided to keep the factory system instead. The NBT EVO CarPlay activation gave me everything I wanted while keeping the original BMW interface, steering wheel controls and sound quality.
Got CarPlay and Android Auto activated on my G20 3 Series. The whole process took around 15 minutes and now everything works exactly like it should from factory. Great service and saved me a trip to BMW.
