I bought my first GS a few months ago and I took a bit of a punt on getting it ULEZ exempt for riding in central London. It’s a year 2000 so it isn’t automatically exempt and everything I read suggested that if it was pre 2003 ish BMW wouldn’t be able to help. So I emailed BMW for a certificate of compliance and the sent one back in German and there were no emission details listed. It apparently isn’t available in English. So I emailed back explaining what I was trying to do and got a very nice email back detailing the emissions for the bike. I sent the emails on to TFL and they have accepted that my bike is ULEZ exempt so mission accomplished! Hopefully this might help someone in a similar position keep their bike. I guess it could also make a bike more saleable to some which might be worth the effort of a couple of emails.
Cheers
