Trailer indicator telltale

[MrFlibble]

Hi all,
I've just fitted a towbar to my 2012 Mk7, and it has a 13-pin socket for electrics. I used a specific, custom towbar wiring kit not a generic one.

Are there any indicator telltales on the Mk7 instrument cluster? I can't see any, and the wiring kit relay box doesn't seem to include a buzzer (and buzzers technically don't meet the legal requirements anyway).

I believe this is an MOT item, so am I going to have an issue with non-existent telltales when MOT time comes around?
