What is TS? We already had a small discussion about TS but no one gave a good answer. I know that TS is a part of the S80 vin. Example: YV1TS32G54F123456 where T identifies an S80 and S a four door sedan. But if the car has a Bi-Fuel engine the chassis code is KU or KV, if it's an AWD in the USA the chassis code is TH
TS isn't used on all S80 and I don't think it's a good idea to use it.
