JB4 for Gen3B 2.0T VAG Group

Hi,

There is map guide in post 1 that I just updated.
Map 5 is not a tuned map that should be used.

What octane fuel do you use?

Oh, I see... I saw it but since it has 8 maps I thought it was a different configuration. Thanks for the fast reply 🙏🏼

Juangonzalezz29 it’s not gonna work by just plugging it in to the car. You need the blue tooth or either the bms data cable. Then you gotta follow the installation link on the first page.

Just got a North American 2023 Tiguan fwd. How well does the JB4 work with this? I had a 22 G70 with a JB4 and it was great. I'm wanting to get one for my new car.

What‘s the meaning of failure code P3AD2? It‘s stable, i can‘t delete it also on stock map 0. What can i do? Any suggestions? BR from Germany.

Hello all,
New member here. Spent the last few hours reading through this thread from beginning to now so I can be a little more familiar with the Group 8 and to hopefully avoid asking redundant questions. Just recently bought and installed a second hand unit for my 2018 Passat sel. Noticed considerable improvements in power. Haven’t bought the wireless option as of yet so I’m assuming I’m running a map 1? I’m I really just getting 1 psi increase with map 1 cause if it is I’m impresssed and more curious if the maps. Also, what map would you recommend for my Passat? Currently the Passat is bone stock except for a k&n panel filter and the JB. Would the wireless option to access additional maps be an overkill? Would I need the wireless option to access the additional maps? Any thoughts//opinions are appreciated. Thanks all.

Wow, I guess this forum is dead. I was really wanting to get a JB4 for my Tiggy. But if there isn't anyone here to answer questions, it seems pointless.

Many users also email in the questions so get covered via email.

Anyone ever get check engine light after installing on the passat?
I have done all the troubleshooting and even sent the unit back and no issues found, Drove the car for a year without it installed and have never had a check engine light
If I plug in the jb4 and select any map and drive then next time I start the car I have check engine light

Have to use vagcom to clear it the app wont
Vag come dtc codes p0106 Manifold/Barometric pressure sensor implausible signal

I have triple-checked the plug and even sent the unit back and no issues found. Anyone know how to resolve this? I want to enjoy the Mountains this time when I go but dont need engine issues
