Hello

I have just theoretical question regarding Traffic jam assist in VW passat 3C, MY 2017.
What all needs car to have to be enable this feature? It is DSG, has ACC, Traffic sign recognition, EPB. Auto-scan is not possible to get, car is far away and is not bought yet. Just to guess or keeping me thinking, are there any chances to enable it or sorry...

Thanks and br

AFAIK, this can be enabled, but not through VCDS. You’ll need ‘that other tool’ to load a different dataset into the A5 module and possibly other modules too.

With the mentioned hardware you should be able to unlock Lane Assist and with this Traffic Jam Assist and Emergency Assist is feasible in the way MasterTommy mentioned.

OP most likely means B8 Passat? 3C is not manufactured in 2017 anymore.

The TJA depends on camera version. If the car has 3Q0 654 camera, it should be fine.

Actually the B8 still has "3C" in its VIN for some strange reason. MY2017 should have a 3Q0980654 camera for sure. 653 was used on early B8-s.

Not true.... Camera 653 is used for VL3- extended pedestrian protection. Early b8-s had 653 for both vl1 and vl3.

Later ones had 654 for VL1.

Thanks. Guess VL3 is not very often ordered from the factory because all of my example autoscans of 2016+ B8-s have 654 but ETKA reveals 653 is still used.

Thanks for support. First I have to upgrade my old Hex-Can to Hex-Net. Then we'll go on. But other tool was mentioned also. I do not know which tool is this supossed to be, will Uwe let us talking about it here. I think he should, since this functionaliyi, probably firmware upgrade, is not supported by our interfaces. Or I'm wrong? When I cet car, I will post auto scan.

Thanks and br
