Brutal...looks like they were only interested in a sale and not supplying the correct turbo...fail.
I warned him that there are MANY iterations of the K04 and he had to be absolutely sure he knew precisely which one he wanted because of the housing differences. And this is why.
If by "him" you mean me, then absolutely yes we had that conversation and I very much appreciate your advice. However, you have to trust the vendor when, after collecting your engine code, VIN, car model, etc., they tell you that the turbo will fit no issues. The only thing they warned me was that the inlet pipe was 5 mm shorter. I'm not a cynic by nature, but I feel they were interested in my money and they hid the fact that they weren't sure of the fitment. So fail it is.
