Just some feedback. I took my X to BMW and they had it for the whole day. Their recommendation was to replace the Turbo as it is faulty. BMW quoted just over R14000 to get this fixed. I then took my X to Stallion Turbo's. They had a look at it and they resolved the problem. The catilitic converters were blocked and this caused a back boost on the turbo. This also caused on of the boost pipes on the turbo to burst. The turbo actually had no problem on it and R1500 later my X is going like a rocket again.

BMW is ripping off their clients and I am sure they did not investigate the problem I had with the power on the X5, or else they would have seen that the one boost pipe was burst. I am really upset with the bad service from BMW.
