e-C4: Check the right brake lamp / Post collision braking system fault

[sugarisbadforyou]

Hi

I'm getting the following messages in the instrument panel of my e-C4:
"Post-collision braking system fault" and "Check the right brake lamp". (Someone rear-ended me, and although it was a fair old impact, the car stood up to it remarkably well with only minimal damage and the right brake lamp is working, looks undamaged and I'm fairly sure was not touched.)

Car Scanner app finds the following fault codes (have cleared them and they reappeared):

BSI:
B1003 55 Status: Test failed, Confirmed. Defined as "air-conditioning" and "telematrix unit rtx or audio navigation" elsewhere on the forum
B1534 64 Status: Test failed, Confirmed. Defined on forum-peugeot.com as "Theme display on the handset and telematic box --> Inconsistent display." (translated)
U1EF3 00 Status: Test failed, Confirmed. Defined on mittns.de Peugeot Forum as "LVDS connection error"
U1208 29 Loss of serial communications for class 2 devices. Status: Test failed, Confirmed

Climate:
B1003 55
Status: Test failed, Test failed (current drive cycle), Pending, Confirmed

Dashboard:
B1534 64
Status: Test failed, Confirmed

Telematics / Navigation:
B1003 55
Status: Test failed, Confirmed
U1EF3 00
Status: Test failed, Confirmed

VIN: VR7**************[VIN obfuscated, can be read by forum staff]

This is the app I'm using: (is there a better one?)

Any thoughts welcome.

What are the definitions of the codes, it can help if people do not need to look them up for you.
