I would also suggest the same as CuturiloD. 99.9% sure it's a wiring problem. If it would be a SW issue, it would give an error on both leds.

Hi, I think this is NOT good.
Try this :
J770 pin 6 - - ->pin 1 left LED
J770 pin 2 - - ->pin 2 left LED, pin 2 right LED
J770 pin 4 - - ->pin 1 right LED

Pin 2 is NOT GND, pin 2 need to be +(positive connection), pin 6 and pin 4 need to be negative connection.
Try to connect LEDs in oposite way.

Is a difference between facelift and prefacelift for led connection!

According to ELSA:
Prefl: Led left and right have same pin2, and pin6 for left / pin8 for right.
J770 pin 6 - - ->pin 1 left LED
J770 pin 2 - - ->pin 2 left LED, pin 2 right LED
J770 pin 4 or (8 according to ELSA) - - ->pin 1 right LED

Fl: Led left and right have same pin6, and pin4 for left / pin2 for right.
J770 pin 4 - - ->pin 2 left LED
J770 pin 6- - ->pin 1 left LED, pin 1 right LED
J770 pin 2 - - ->pin 2 right LED

Your modules are from Facelift, your car is Facelift model > MY2015+?
Olso like CuturioD - i sugest to change pin connection 1<->2 in door T2 plug or on led lamps, depending of which is more easy for you.

Maybe one of you can help me with pinout for led lamps, i can't see pin number on the plug or on the lamp. I manage to find positive and negative pin but can't tel if positive is considered pin1 and negative pin 2 or reverse. Can any of you have a visual check on their lamp?

Thanks in advance.

If i know it right:
1. When radars are new calibration is required
2. Calibration is required when radars are used and are not from the same vehicles
3. Calibration is not required if both radars are from the same vehicle

Yes to 1 and 2. But calibration is required also if you change the radars to another vehicle. VIN changes it wipes the calibration.

Are these swa2.0 or 3.0? 3.0 loses calibration as it also incorporates component protection scheme.

SWA3.0 modules have CP. If these don't then they're SWA2.0 max.
