Dear all.. my normally trusted jeep 2.8 CRD limited, 2003 is playing up.. MIL light is on but my two code readers and my local garage show No codes.. took to a Jeep dealer and they told me that the turbo had failed.. so yesterday I removed the air box and a few other bits and pieces to get to the turbo. I could clearly see the compressor rotor and it span very freely by hand, no slop or damage. Clean and shiny.. having removed the outlet and input hoses I started the engine, sure enough the turbo span, I carefully put my hand near the inlet and it was definitely sucking air in and the outlet was blowing well . I put the outlet hose on , the one that would go to the intercooler, got my Mrs to gently rev the engine and it blew like a leaf blower, plenty of wind.. it did now make a wining sound at higher revs but it sounded correct considering the blades were rotating at thousands of revs.. with the hoses on you don't hear this sound. So in your expert opinions do you agree the turbo is doing its job.. but I still have the symptoms of very poor acceleration over 30 mph, it revs up when not under load almost as normal but going up any slight gradient it's really struggling to get over 40 to 50.. it's flat out and just creeping along.. all advice would be great. One point, at the start of the problem it did loose power but half way through the journey it came back to life again. So I am more thinking it's not mechanical .. I am going to look at the MAP sensor now and give it a clean .. jeep said a turbo was going to cost thousands.. stealers lol
