Apologises asking but out of curiosity plse I always assumed u shouldn’t delete the egrs fitted with a DPF , plus don’t know what the regs are in Norway
Once again hope u didn’t mind me asking , many thks

It depends on what exactly was done to the ECM and there are no easy answers without interrogation of the ECM. If the EGR's are disconnected the ECM may have been remapped in an attempt to eliminate them instead of a software patch. Perhaps it is this which has somehow gone wrong.
Can you still see the EGR's physically attached to the engine? There is one on each side just below the engine cover.
The EGR both have been phisicaly removed not only software patch.Bas Bultje

Just got a call from the garage they have not installed the sensor from the DPF when instaling the new DPF they just left it out.
After installing new sensor they need to give message to ecu that new dpf has been installed. so that might be the problem with the car not starting. and the EGR fault is not a fault that has any with the problemBas Bultje

Hi, I bought the car with EGR delete and it has been approved by Equivalent of MOT. Without any marks in return. So i hope noting is going to be of a problem therBas Bultje

OK so reinstating them is not an option for now. It might be worth having a look to see if any of the DPF sensor connections have come off (long shot!)
Beyond that, was the PCM updated to take account of the new DPF being fitted? If not you can do it with your GAP tool and proceed as follows. Just make certain you have a battery charger connected whilst this procedure is being carried out, and all internal consumers are switched off
With the ignition in the on position (engine off) Connect your GAP IID, > Main menu> select Service Test> select PCM engine> select DPF replacement> (follow the on screen instructions). Once this is done start the engine and let it run for about 2 minutes, switch off and repeat once more. Then ign on again and go back to the GAP main menu and select Service Test again, > select PCM engine> select Fuel Lift Pump Reset, and follow the instructions on screen. Once finished start the engine as before for two cycles and switch off. Switch back on and read the fault codes for the PCM!
See what that brings, you never know this might be your lucky day.
Remember though, battery charger must be connected and everything switched off before attempting this procedure. If the voltage drops whilst whilst this is being carried out it could brick the car's ECU rendering it kaput.yµ (idµ - eAµ) ψ=mψ

You beat me to it, see my last post.

My D3 came with a DPF and I was told in no uncertain terms that the DPF had to go if the EGRs went. It was explained to me that a functioning EGR system was required to perform the DPF burn off, so without it the DPF would progressively fill up and then fault.
The mechanic might have been talking out of his backside, but it certainly sounded plausible. This will be the acid test I suppose.

Update. Today with a icarsoft conected i got following error message.
Car still doesnt want to drive more than limp modus. Runs stationary good.
I did with the icarsoft tell the system DPF has been replaced.
Sensor has been installed, Original LR part.
What to do now?Bas Bultje

Stick your head in over the rear of the engine and see if you can smell exhaust fumes. If you can there's a leak in the pipework which needs rectifying. You should not smell any exh fumes from that area.
Or, it could be the other way around, and you have a blockage causing the pressure difference.yµ (idµ - eAµ) ψ=mψ

DPF differential pressure sensor where is this located the problem can be blocked line but i dont know where its located.
What I have seen (read) is there is a pressure difference between the to pipes getting not correct information.
What to look out for in a failing DPF differential pressure sensor
When the DPF differential pressure sensor stops signaling the PCM to regenerate, the DPF can become completely obstructed by contaminates and fail. Here are some signs that indicate the DPF is not regenerating properly due to the DPF sensor failing:
Poor engine performance
Poor fuel economy
High engine temperatures
High transmission temperatures
An increase in black smoke (soot) from the exhaust
Check engine light
When the DPF fails, exhaust gases can not be fully purged as backpressure pushes exhaust back into the combustion chamber causing DPM or soot to mix with the engine oil. Soot is abrasive and when mixed with oil, will cause premature wear to the engine bearings. The fuel that should be escaping through the exhaust during regeneration will also only partially burn. This leftover fuel will then wash away the protective oil film on internal engine components and cause catastrophic failure.
A DPF pressure sensor is vital to the longevity of the DPF, and if the DPF becomes completely obstructed, the regeneration process will not fix it. It will need to either be removed and professionally cleaned or replaced, both options on average costing thousands of dollars. Much more than the cost of diagnosing and replacing a faulty sensor before it’s too late.Bas Bultje
