Evening Team,

Well my trusty 2006 XC90 D5 has developed a bit of a problem over the weekend. The car has 147,000 miles on the clock.

The engine management light came on for the second time in as many months, the first time the garage could not find the errors as there were too many in the system to isolate the cause. The engine management light was re-set along with the reams of codes. This Saturday the light came on again so I went straight to our garage as instructed. The engineer plugged in his test equipment and pulled the following codes - 6662, 6663, 1600 and 1000. I have looked up these codes and see that they appear to be sensor pressure issues. Initially no adverse effect was felt from the car until we went out in the afternoon. On the was back from town the gear changes became aggressive and then appeared to go into limp mode as was unable to maintain any speed above 50mph. On the way in to town it was fine.

So my question is, do we know what could cause the error codes 6662, 6663, 1600 and 1000 to appear all at once and to also affect the gear changes and to put it in limp mode.

Thanks in advice Team
