United-Kingdom Mini One D 1.4 auxiliary belt tensioner replacement

Hello, I am new to the forum and I'm here to seek your guidance on my topic in question,

Mini is a May 2005 build and is a 1.4D. The car is a relatives, and as I was servicing it yesterday I noticed that the auxiliary belt tensioner had a lot of play in the bearing and it 'whines' when engine is revved.

Looking at the tensioner and it seems it isn't sprung loaded or self tensioning, there was a white paint mark on the tensioner bracket behind of the outline of the wheel.

My question is: how do I properly slacken R&R the tensioner and set it to the correct tension? And are there any special tools needed?

I'm having trouble searching for this part from the big named motor factors where I am (eurocarparts) and seems the only price I can quote is from BMW at £126 just for this tensioner which in my opinion is expensive.

Any comments much appreciated.

You could use RealOEM - online BMW parts diagrams - to work out the part number you want as that might help a non-Mini place locate it.

This should get you to the parts diagrams for a 5/05 One D: * Online BMW Parts Catalog

And this should get you to the belt tensioner diagram shown below: * BMW R50 One 1.4d Belt Drive Water Pump/Alternator

The tensioner in this diagram lists at £116 (£4.25 extra for the bolt!) - you can paste part numbers into this site to get full dealer price with VAT:

I'd like to know how to replace the tensioner as well, from the alternator thread I can see replacing the alternator means removing the front bumper, hopefully replacing and retensioning the tensioner doesn't need the bumper off.

Likewise, any special tools required.
