200 tdi alternator belt

Hi all hope your enjoying the weather
Iv'e got a series 3 with a 200 di engine in and the alt belt is slack but adjusted fully so i think its the wrong belt this one is 13mm x 1100 does anyone know the correct size of a 200 tdi alt belt before i order one, Im also thinking it might be the wrong sliding adjusting bracket so if the correct belt for a 200 tdi belt is 13 x 1100 then it must be the bracket thanks all Cris

It is non standard I have a 200di and this ebay item is what I have fitted currently [1050mm x 13mm], where is your tensioner bracket fitted?
200tdi original alternator was driven by double pulley on steering pump.
I made my owner tensioner arrangement.
