Having had problems with this thing since the day I bought it I thought it would be sorted now after 2000€ worth of repairs...
Here is my love-hate story with 3.0 V6 CDTi so far:
January 2009 @ 238,500km - EGR valve went the same day I got it, but the fault was intermittent, so only replaced it 8,000km later when the fault light was constantly on and the car was undrivable due to severe power loss. I bought a used EGR, which broke again in just over 10,000km. There were huge plumes of black smoke coming from the back, along with the famous fault light and power loss.
August 2009 @ 257,000km - Replaced with new EGR and so far so good, no smoke.
April 2009 @ 246,000km - I noticed the car was juddering under partial throttle and smoking gray under hard acceleration. This was caused by fouled injectors.
October 2009 @ 258,000km - the car started running on only 5 cylinders, so replaced all 6 injectors with 2nd hand ones for 500GBP.
November 2009 @ 260,000km - Catastrophic power loss under acceleration. Wouldn't rev above 3000rpm. It nearly killed me once. This was intermittent.
December 2009 @ 262,000km - Cold starts were starting to be a pain. Finally diagnosed as blocked suction control valves in the high pressure fuel pump. Replaced that and the car was back to "normal".
New Year's Eve @ 263,000km - Fault light back on. Tech2 reads low boost pressure. Again, this fault was intermittent.
January 2010 @ 265,000km - Low boost pressure coming up more and more often. Diagnosed as sticking variable vanes in the turbo geometry. New turbo from e-bay.
February 2010 @ 265,500km - Annoying acceleration behaviour. Turbo feels as if it's going on-off-on-off-on. This fault was present in Jan 2009, but as now everything's been sorted, it's much more annoying.
The last problems were jerky acceleration and overall, poor performance at high speeds (over 120mph). Top speed was only 130mph as opposed to the 140+ when the engine was in top contition. Everyone suspected a faulty air flow sensor. I took the sensor out earlier, gave it a good squirt of brake cleaner and put it back in place. Started the engine up and gave it some revs. For the first time ever I could hear the turbo whistle under 2000rpm. Have not taken it for a test drive yet, because I'd lose my parking space Tomorrow is a new day
So...What do you think chaps? Is it finally sorted?
