Changing Turbo on XC90 2007 185 HELP
I'm in urgent need of information from someone that has done this change on a XC90 185.
For the life of me I cannot see how to change the turbo without either dropping the engine or taking apart most of the car to get access to the relevant fixings. I have taken most bits of for access from the bottom and have started to remove parts from the top but I have hit a brick wall now because of some components I want to remove but physically cannot get to the fixings. I would like to check for play on the turbo and end float before I go any further but cannot even get to the jubilee clip on the inlet to the compressor side of the turbo. Background is excessive oil consumption, Flaky power delivery for a couple of weeks and now no boost whatsoever, Plugged up VIDA which shows a couple of glow plug faults and an o2 sensor fault. HELP |

02 sensor would cause a lack of power and glowplugs could put engine light on,
I have a feeling just replacing the turbo is a waste of time and probably won't cure your problem, Have you checked for boost leaks, ie had the intake system smoke tested, Is the swirl flaps on front of engine ok

the turbo is a B***h to do... to get at the pipes and jubilee clips you need a really long flexible drive best to get a 1/4'' 7mm socket then lie on ground under car and feed this up from behind cross member whilst looking vertically up at the clip.... you will also need this to remove the oil drain pipe, cut the rubber water pipe just at the turbo and do not bother trying to open banjo bolt... you need to take the transfer box off which involves taking the Prop shaft off, and the drivers side drive shaft.. if the drive shaft is stuck in the hub then take the whole hub off..... also drain the oil and take the oil cooler off( or at least let it hang free. I advise taking the DPF off first, then the Prop shaft, you might like to cut some metal off the car to make things easier. there are some pictures on line of where to cut, but it becomes obvious when you try to slide the transfer box to towards the drivers wheel to allow it to drop off the collar it is almost impossible to get back in without this (alteration) I have had mine off three times and replaced eventually with a span new turbo and today I am taking the car for its last spin, it has used 5 liters of oil in less than 600 miles. Current thought is that it is the pcv or rings is causing the loss of oil, in any case I am giving up for now.... |

Swirl flaps are not in operation but have been like this for the last 15000 miles without issue. I have purchased all parts to repair this but they don't arrive until Tuesday.
The glow plug faults have also been there for atleast the last 15000 miles. The o2 faults are new though. PCV system is not blocked I will try with live data and see if it throws anything up. I have put the car back together for now because I myself am not 100% convinced its turbo but thought I would change it if it wasn't to big of a job as I have a spare good turbo that cost me nothing. It is clear though that it Is a big Job. Thank you for the input |

The turbo will come out without cutting any water pipes or metal off the car

Cutting the little rubber water pipe that costs about 6 euros and which is extremely difficult to get out is worth it, getting the turbo out is not the issue, it is getting the transfer box out that was almost impossible, and was impossible to get back in without the little notch. also be sure to disconnect the bracket that holds the metal pipes from the DPF pressure sensor or you will have more money to spend... |

Update
Fitted new glow plugs which has cleared that fault. Did a regen on the particulate filter because of a high pressure reading. Now this was interesting because during the regen I had yellow fluid dripping from the exhaust. This is the first forced regeneration that I have done or seen. Is the yellow fluid from the exhaust normal. I can only assume it is two things and that would be engine oil or a by product of all the fuel being shoved through the motor during the regen. The yellow fluid didn't have any obvious smell. The regen wouldn't complete (tried several times) although I got the pressure readings down to an acceptable level I will be fitting the swirl flap assembly hopefully over the next week or so. No fault codes from this even though it is not working. All I have now is an one o2 fault but the car is driving again and appears normal. I have had no dash messages other than soot filter full which is normal for us because of the type of driving that the vehicle does but this gets cleared again through normal driving. The message is becoming more regular probably because of all the oil being burnt. |

Normal driving will see the car regenerating the particle filter by itself, all it takes is a 30min drive on a motoryway once every 2 tanks of gas. If you don't do that, then you should plan a 30min outing with the family once a month and use the XC90 for the journey.

Like I said with the type of driving my wife does this message is normal (school run) and gets cleared when she goes and does the shopping although even then I don't think it is completing a full regeneration but it has been working like this for the last 18 months without issue. Oil consumption is a problem though which had only raised its ugly head over the last 2 months and is I believe causing the clogging of the DPF. I need to get the o2 fault sorted and I will fit the new swirl flap assembly along with a full clean of the egr and throttle body(still feels weird saying that a diesel) After this work if I still have high oil consumption then it will be a turbo change. |
