Response To Roy Macdonald Bevel Gear
This is my 2nd XC90, my first being a first month release 2003 model., It had EXACTLY the same slow pullaway algorithm built deliberately into the ECU by the manufacturer. This only shows on full power pull away and insn't a hesitation just a slower controlled realease of the power. As I said, the chief XC 90 designer mentions the slow release ECU, and the reasons why it was required. Why would I make it up????? I went to the pre realease private viewings and read a lot about the car before it was released
Having had 2 Audi Quattros, I do have a little knowledge of AWD and permanent four wheel drive characteristics. I also had a 2.5D multitronic Audi A4 which also has a slow release torque algorithm built into the ECU, and for exactly the same reasons previously mentioned. TO SAVE THE TRANSMISSION. You should check the other forums as I mentioned, you will be surprised. I have no axe to grind with Volvo in general, I have had 3 new Volvos 2 x XC90s and 1 x V70. All until now, have been fine. I still love the car. But the spline sleeve in the Bevel Gear transfer box is a very poor design. If your main bearings failed at 50K you and everyone would be upping arms. Why is this different? Engineering will ALWAYS fail at the weakest point. Putting a spline sleeve between two gear boxes, transfering this amount of torque is definately the weakest point. Just look at the line diagrams and pictures from the US forums. |

Rockhopper.
Are they charging you for the repair or are they doing it under warranty? Please let me know. Kind regards Chris |

Although I couldn't find anything on the XC70 other than oil leaks from the bevel gear transfer box (which could obviously lead to a problem if not noticed) there was plenty on the XC90. As one American owner put it "the car has a mismatched engine and transmission" (This is on the petrol T6 with GM autobox) I saw a post that said Volvo have redesigned the bevel gear transfer box and that it is now 50% stronger. However it is also quite a bit bigger so will only fit cars with the new chassis from 2008. I think this does indicate that Volvo think that the original bevel gear transfer box isn't strong enough, but I would suspect that it only came to light with the higher powered engines of the later models, remembering that the majority of cars sold here after launch were 163 bhap D5's My guess is that it's with later models with the redesigned 185bhp engine that are driven hard that can cause the problem to appear.

No AWD - Add me to Your list
Please add me to your list of people that have found they don' have AWD in the snow. (See my other posts).
Problem not fixed yet as I object to shelling out money of something that appears to be a known problem. I have used the link provided by mixam in another post to put this into watchdog. Cheers Last edited by midge; Feb 11th, 2009 at 12:07. |

Guys,
If you have this XC90 Problem even if you car is under warranty please let watch dog know that this problem exists. Every single notification they get will help the cause. Today it's Snow. Tomorrow it will be floods! Are we putting ourselves at risk? |

Not really, given the millions upon millions of 2WD cars on the road which cope just fine.

Watchdog and Bevel Gear failure
Yes, I too have registered with watchdog this failure. And no, Volvo refused to contribute. They stated and I quote:
"Due to a lack of loyalty not always using Volvo for Servicing" I have asked for this in an email. Still waiting. I mentioned to Volvo the fact that Asgard Burntwood and Speeds at Burton have both closed, so I use Squires Midlands Volvo Specialist who are run by the ex Asgard Volvo service team. I also asked how many new Volvo's do you have to buy to be considered "Loyal". I've bought 3. May be Audi or Merc again next time. Point of Fact: It is now European law that a non-franchised dealer or service specialist can perform service work without effecting ANY manufacturers warranty. As long as the services and repairs are carried out are in accordance with the manufacturers service practices and genuine manufacturer spare parts are used. The manufacturer can stipulate however that warranty work must be carried out by a franchised dealer. |

Thats my Point... so many cars that are on the road that don't know that they have a problem due to the fact that there is no warning signs to tell the driver that they only have 2WD in a Vehicle that should have 4WD. There are no sensors to give the driver feed back that such an import problem exists until it's to late. I.E Stuch in Snow, Mud, Ice! Or even worse in a Valley where the river has burst it's banks! Yes a bit alarmist but the point is if the owner or driver of the vehicle doesn't know there is a problem then they could be at risk! |

Volvo have redesigned the Bevel Gear Transmission box for new XC90's anyway, so that should cure the problem Roy
