D5 (2005 on) XC 90 D5 Euro 4 limp mode

[AUS T5]

Hi guys
I have a recent purchase which is giving me a bit of strife. It's a 2006 XC 90 D5 Euro 4, one lady owner from new with 220,00 K's on the clock. Her local authorised Volvo garage wrote it off so she stuck it on Ebay and thats were I picked up from. It was locked into limp mode and so I took it into my local indi Volvo garage and they found it was the turbo actuator at fault (see image) As can be seen, it must have had quite some pressure on the arm since it looks to be quite badly bent! Anyway, they replaced this (with another used one) and it was fine again, so I sold it on to my son.
That was last Xmas so here we are 4 months later and it might have done the same thing. I have started to strip it down to see if I can fix it myself this time and save $675.00. I am also thinking the engine mounts could be faulty too, no service records so no idea if they have ever been changed. Since I was getting the "tug boat" noise from the oil filler hole I did do the trick of blocking off one of the pressure lines to the mounts which stopped the noise, but I don't think this is relevant for the E4 since I understand it is not linked to the turbo like the E3 is.?
I have checked the EGR for soot accumulation and it's very clear, just very fine layer. I have also pulled out the MAF and sprayed it with special cleaning fluid.
I do have a new plug in fault finder and amongst other numbers it did give me a line of English script saying the #5 injector is faulty but being a novice at these machines I did manage to delete this but can't get it to re appear. Looking at the engine from the front, is #5 cylinder on the right or left.
Looking at the engine mounts the front looks a doddle to change but the back looks like the whole engine has to be pulled out aaaaahh.
As yet, I still havent been able to get a visual on the actuator or even the turbo, from the top or underneath
Any tips on shortcuts much appreciated. Also, how does one go about getting Vida printouts.
Thanks
Phil
