I bought mine in 2009 new of Wren and changed my plan and had no home for it till 2011 at that point I was aware of the issue regarding the compressor and got onto Wren about it I send the turbine back to them unrun and got them to carry out the upgrade of the compressor and the diffuser at a nominal charge as technically the turbine was now out of warranty the whole issue was dealt with in a very professional manner by Wren
