Has anybody changed the fanbelt tensioner on a 1.9TDi?

Had a squeeky/chirpy noise from the car. Asked my MOT man while getting 4 wheel tracking done what it was and he replied 'the belt'. A few weeks later it started shredding itself as i drove into the carpark at work. After having the belt snap on my previous Ibiza, a PD130 and knowing i could keep driving for a while due to the electric water pump etc i wasn't too worried. This one is a 160 Cupra. I fitted a new belt and then noticed a quiet occasional squeeking again. Then as i started it at work one day last week there was a very loud knocking noise coming from the engine bay. I opened the bonnet to try to pinpoint where it was coming from and realised it wasn't directly connected to the revs. At one point it was quite a riffy drum beat! Initially i thought it was coming from the top of the engine. Thought cam but then ruled it out as it wasn't a regular banging. So then decided it was injectors. Then on the way to work the next morning discounted that because the engine note or power didn't change. I should note that when i got home i went to have another look/listen and it had stopped. It was a couple of days later when i had another listen i realised it was coming from down by the alternator area. Then i decided it was either the alternator or the tensioner. Then upon closer inspection i could see the tensioner pulley moving when i heard a noise, which by this point had changed. No longer banging more more of an intermittant groaning/chirping.
Well to cut a long story short, It's shreaded it's second belt and today i tried to fit the new tensioner.
Got the old one off after moving the alternator and spotting the bolt...
I had been trying to undo it by smacking it with a chisel and getting nowhere. It's off now and i couldn't get the new one on as with it's pin installed to wind it around to max to allow the belt to fit over it easily, the pulley fouls the bodywork in the engine bay. Suspecting i'd regret it i took an angle grinder to the pin to release the tension and in my theory, allow it to fit into the hole. NO it DOESN'T!
It's closer to going into the hole but the pulley is still fouling on the bodywork. I don't know whether to release the engine mouting on the driver's side to try to jack up the engine a couple of inches or remove the massive casting that holds the tensioner and power steering pump.
Has anybody changed this annoying component?
It's an 05 Ibiza 1.9TDi PD160
At the moment i'm driving 10 miles to and from work and charging the battery up every night. It's the world's worse diesel/electric plug in hybrid! :giggle:
