From what I hear the only "common" problems with the 2.4 diesel were the issue with the EGR valves and inlet manifold on pre 210 bhp cars and with the DPF on 2006/early 2007 cars. The DPF problem re-appeared on early 210 bhp cars and has since been fixed. Both issues could lead to the stuttering that you describe.
Sorry for maybe a simple question, but what is this DPF?
I must agree with others, this is an earth problem, checked the the earth on the motor to the battery earth with a multimeter, nothing. Grab the biggest jumper lead I can find and hook it between the earth on the battery and a big bolt on the motor. WOW all displayed faults gone, motor turns over and starts. (the boot also opens).
I made a temporary lead between the spare battery terminal and a bolt on the motor to be sure it will get me to the dealer tomorrow, where I will have them fix it and give me compensation for a battery I didn't need. So if anybody has these strange error messages, try the jumper lead trick, even if you had to use it to get you home.
Has anyone else tried this before and found similar results?
1. I was told to use only 50 ppm Diesel (A bit frustrating, as there are only 2 petrol stations close to where I stay that have this, but anyway).
2. The specialist said that after extensive testing and diagnosis (the car was there for 3 weeks again), he said that the car was running too cold. So they ordered a new thermostat, and all is well!!
Hey Shaun, sorry to hear about the problems. Just a quick couple of questions please. When the dealer had the car for those three weeks, I see you listed what they said, but did they change anything else during that period...? Did they clean the earths up or change any wiring? Have you had the battery changed?
The earth connection can definately be a problem, you see, if the connection has a aluminium lug or where it connects to is aluminium, if it is not cleaned really well, the aluminium reacts with the air and causes an oxide layer ( usually looks like this white chalk/dust ) and this is of high resistance. Which means that it would not be a good connection even though it looks really good.
I can't say this is the problem, but if things act up intermittently, a voltage problem is highly likely.
Shaun, where abouts are you mate?
