Hi, help needed please. Done searches etc and been under the bonnet 2-3 times and asked a mexchanic even but cannot get to this torx securing bolt to get it off. I can't put in the new tensioner and adjusting bolt till I do and it should be such pi$$ easy job.Belt is screeching, been like it for yonks and knackered old adjusting bolt and drilled into tensioner so cannot salvage that...although it's holding firm cos the torx bolt can't be moved. I can't fit a torx on the end of a socket to get between panel and bolt.
I've tried sticking the torx in and turning it with a spanner but I'm never gonna get the elbow grease behind doing that. I must be missing something as it seems to be real bad engineering or someones put a wrong bolt in...if it was a hex it'd be off easy. Is there a tool or spanner that will fit it. I can't bring myself to go to a garage just yet as kint and I can see easily how to do it all...any advice appreciated ta..
I know it's known to be a dodgy set up, from searches and it's different to VTR's etc..

It's the one in the middle of the pic to the right of the belt and pulley and nearer the grond than the others...a torx bolt and can't get any tool on it..
