Well, DPF is in a very good condition. Keep an eye on the gauges a little bit further.

About cam chain...I suggest you to also keep an eye on it. My last 6 has around the same value. You will see that the value it's not always the same , it varies (in your case) from 9 to 9.7 approx.

So what I am trying to say is, maybe this is it, and you will have the same value for 3 more years. Maybe this value will become higher and higher. Then you will have to replace it. Critical value is around 10.5, at that time the MIL will show up, and it will be time to invest some money.

A little update. I didn't saw REG_DIS gauge. Hm, IT seems that DPF is filling a little too fast, since it has 0.5g/l and only 8 miles. In kilometers this would be around 150km when active regeneration will take place.

Add a gauge to check the injectors values, then name starts with 'FI_LRN_01', FI_LRN_02' and so on.

Thank you I have some of the injector values here but I also ran the injector calibration cycle so hopefully it will improve.

I only do motorway driving I work in town which is bumper to bumper slow traffic in the week as did the previous owner who did not use it on a weekend.

Before injector calibration (sorry couldnt get the other injector figures... this also shows an oil dilution of 76.3. What does Oil change 1 & 2 mean, I know 1 is obviously the miles since last oil change since it was reset but what is 2?

PM_ACC would also have higher values that PM_GEN and so on..

If PM_ACC is triggering the automatic regeneration then something is not ok. This would be the first alaram.
Since a while the automatic regen on my car is triggered by PM_ACC when it reaches 6.0, where instead in the past the regeneration was triggered by PM_GEN.
The issue is that now regeneration Interval is about 250/300 kilometres instead of 450/480 kilometres.

Any idea if about the cause if this?

My car have 225.000 kilometres.

Hi, it could be that egr is the cause, but I think that filter is partially clogged.

My forscan data show negative value for cam stretch (-6.99). Is it normal?

Hi guys, a have a problem with the chain or somewhere else. I replaced it with all related components and after start the dpf light still flashing and after a short drive engine lamp apears. The stored trouble codes are for difference between cam and crankshafts and for EGR flow. Engine works good but the lamps can not be switched off. The difference is 8,78° and is in the specifications. Please help with opinions.
