(Side Assist) / (Blind Spot Detection & Rear Cross Traffic Alert) retrofit

I think 5Q0 and 2Q0 will work on T5.1 as a BSD, not sure about RCTA.
I know a lot of people who own T5.1 and use 2Q0/5Q0 but all of them upgraded their BCM from 7H0 to 7E0.
 
Ok, Im not worried about RCTA.. only 7E units with revision C if that works on t5.1. - standart is B and thats not tooo cheapy from OEM ( after car accident ) - im looking for my friend cheapest way.🙏 many thanks 4 help :)
 
All complete now on my t6.1. Correct datasets obtained from vctool database. Now have to go through the dynamic calibration drive I believe. Part of the self learning of the modules i guess.

yea thats make sense and only thing can be wrong is LED wiring - factory is in cluster T5.1. with green mirror on right sight - if i use 7E or 2Q/5Q i need to change clusters or its adaptable via coding or it doesn't matter ? that all i need to know.. 🙏 🙏

is your cluster HighLine or LowLine ?
 
and wiring is its same like t6 or i need on same like t5.1 to "cluster" - with 7E/2Q/5Q units . i mean still need wiring and looking on kufatec which one i need
non or RCTA is going to cluster , they use Leds (indicators in mirrors , power and proper CAN-BUS
 
Report back, have put 500miles on the van since this retrofit.
Everything seems to be working perfectly.

Scanned the van on Friday with vctools and no faults reported back on these modules. I think the dynamic calibration is probably more than likely done its thing and will continue to do so.

I had a factory fitted 7E side assist on my T5.1 caravelle with 7H0 BCM , but you will need the dash swich to turn it on/off... no Assist menu even on the 2D colour instrument cluster. I still have the originall radars with holder and the dash swich in my garage after the upgrade.
 
RTA system operates when reversing gear is engaged, brake pedal is not depressed
and "negative" speed of RTA equipped vehicle is within (1-7.5) mph = (1-12) km/h.
The speed of "rear crossing" vehicle must be greater that 2.5 mph = 4 km/h.

YELLOW zone is the area where time to possible collision is within (1.5 sec. to 2.5 sec.)
RED zone is the area where time to possible collision is within (0.5 sec. to 1.5 sec.)
BROWN zone is the area where time to possible collision is below 0.5 sec.

And again huge credit to @mmi for his involvement and collaboration ;).

Confirmed :cool:


Contrary to standard color-coding conventions, VW's Rear Cross Traffic Alert displays a red indicator in the instrument cluster for low-risk situations and a yellow indicator for high-risk situations and active emergency braking.

I really wish I had this on the 2Q0 radars 😭
 
Could someone advise on these radar errors? I installed the radars on a T5, and now I’m getting the following faults.

Do I need to perform calibration/adaptation (for example using fans), or is the problem likely something else?

P.S. There is a high chance the radars came from different cars. I made the wiring harness myself. Could the issue be caused by radar incompatibility, parametrization/coding, or should I first look for a problem in the wiring?
