Got a squeaky noise when turning wheel and first job will be to try changing the belt (A6 2001, 110bhp 1.9 tdi)
 

Looks like there is two belts, one wrapping around the main shaft and powering the AC with a tensioner and another wrapping around the main shaft and driving the alternator, power steering and a fan. I obviously want to change the drive belt but it looks like I'll have to taken the AC one off anyway to get that one off - not sure how I'll deal with the fan. Has anyone changes this without taking the front off?

take  front off  bud  if  not  it is  pain   kev

Had my cambelt and water pump and lower pulley changed this year. Front end should come off for best access. Plus it's worth checking the pulleys etc when you do change it.
