I have just bought a DISA from Ranski and went to fit it today. I actually found mine had been changed prior to my ownership as it was in perfect condition even though the car has completed 106k miles and has the later part number 7514874. So will be able to pass on the DISA I had from Ranski (pre facelift 3.0i 35k miles part number 7502275) £30 plus £4 P&P.
