Serpentine tensioner .

[Sunny43.5]

Has anyone changed the serpentine belt tensioner on a 2012 T5.1 2.0 turbo , mine is rattling and I thought it was just the bearing in the pulley but sadly not .It seems that the actual spring that holds the tensioner has weakened as it wobbles around when idling . I tried my best to remove the whole tensioner but some sick sod in VW decided to put the head of the bolt in such a awkward position that I was unable to remove it . I even unbolted the air con compressor but still no luck its stuck right up against the block and the only way you could get a socket on it was to remove some huge engine part as it has a bolt blocking the access to the tensioner bolt . Maybe VW have some sort of very long ratchet ring spanner the can be used , any suggestions would be helpful .

Update time , I ended up paying my local VW specialist to do the job . Ok it was expensive as they had to remove Aircon pump and then the whole front engine mount had to be removed just to get a lousy 13mm socket on the tensioner as the bolt was blocked by the mount . They also replaced the serpentine belt as a precaution and the alternator pulley assembly as well as it was worn badly . They also did the 130000kay service as part of the job $1450 was the end bill but was worth it for peace of mind .
