Just thought i'd share this with the community, particularly those in the UK/Australia with the CRD. I've just had my first 10,000km service, and boy is there a difference in the throttle response! The dealer didn't mention any updates were available with the scan tool, so in short a simple oil & filter change did the trick.
When I bought my Compass CRD, I was told the grade oil used was 0W 40 Full synthetic. I can only assume they used this for the cars engine brake in period only, because when they serviced it - they replaced the oil with 5W 30 low ash oil for diesels. Acceleration is much more responsive, and a lot smoother across the whole rev range.
For those of you with the CRD, you might want to make note of this if you come across it too. Since I bought the Compass, on cold start it would make this knocking sound at the front of the car. I of course asked the dealer to check it out when I dropped it off for the service, and it turned out to be a missing bolt for the intercooler. This was replaced and the noise is gone.
I can't fault anything with this car, I love it!!
