After months of waiting they did found the sensor, but nothing, it still misfires even with a new sensor. The last BMW service in my country confirmed that they can not fix it, they hand me the car today and they apologized.
They know it's something connected to the VVT, when they disconnected the sensor it doesn't misfire. And problem is I can't even sell the car 
Ok so I got my car today, they checked everything and pin point the problem in the Valvetronic sensor/computer malfunction.
They checked the chain tensionaire, it was the newer one so they didn't changed it.
They checked the chain and the gears that the chain is connected to, all working good.
They checked the CCV and changed the return pipe as it was cracked.
Finally they checked the Valvetronic and found out it wasn't working at all. So they disconnected it and the car stopped misfiring.
They told me the new Valvetronic sensor and computer costs over 500EUR new but they can find a used one from Greece (Closest official BMW importer) for 120 EUR.
Ok an update to those that are following the thread.
I did take it to a trusty mechanic in my area and they looked at it and diagnosed it with DIS.
Same error code as before 274E Misfire Checksum Error
It's a little bit weird for me, I study computers and Checksum Error or Syntax Error is usually RAM/Computer problems.
According to their diagnostics the outlet, inlet and chain are probably not calibrated or chain has skipped a tooth.
They told me they will adjust the No.4 and No.5 Adjustment unit including the chain and told me to pray that they are not broken cuz they will cost over 300EUR each

Well INPA didn't show any faults, everything looked operational, no error codes.
All Cyl. were working good around -1 to 1, when I rev it all values are 0 when I let go of the gas they return to -1 to 1 except the Cyl.1 was going to 7-6 and returning slowly to 1
However when I scanned with PA Soft, everything was "No Error Codes" but the Valvetronic tab had "No Data" which is weird 0_o. And I am beginning to think that the vavletronic motor or sensor is faulty.
Just an update, I will take the car to a mechanic 40km away this week :).

Ok hmm, can you tell me which software is able to diagnose this problem? PA Soft isn't giving any good information. Says there are no error codes. However I have noticed that on the Valvetronic page on PA Soft it says "No Data" while for everything else it says "No Error Codes". I am getting INPA this week and I will record a video with all live data.

I am going to change the ignition coils tomorrow all I don't think they will cost more than 100EUR for Bosch.
According to last diagnostics the MAF is getting correct readings.
I will check for vacuum leaks as the engine is making a whining noise when cold. Same noise like a belt noise but much quieter.
The Vehicle has 127,000 km. I checked with TUV Hessen when I was buying the car they gave me documents of every 2nd year registration so I am sure they are real.
Well the vehicle previously was burning oil so a general rebuild has been done (It doesn't burn any oil now):
*Head gasket
*Piston Rings
*Valve Stem Seals
*Crankcase gasket
*Crankshaft Bearing
*Spark plugs
*CCV (Without hoses and without valve)
*Crankcase position sensor
All OEM from Germany
However my mechanic tried with a new MAF he told me it's fixed but when he took it for a test drive it began to misfire again.
I only have PA soft and it's giving me 3 errors:
*278E Misfire Detected, Checksum Failure
*Misfire detected on Cyl. 4
*Misfire detected on Cyl. 2
Interesting thing is if I disconnect any sensor like the MAF and MAP (Manifold Air Pressure) the misfire is completely gone, but then the car doesn't start in the mornings and it's really slow.
Car was taken to a diagnostics but here in my country the only thing they have is DIS and it says that there are no fault codes and Cyl. 4 isn't running right/stable.
I left the car for checking but I have no idea what they checked, they just told me they have no idea what the problem is, so I am guessing they checked the ignition coils but I am not sure about that. There is no official BMW dealer here they shutdown last year so I am left with taking the car to private garages.
I am getting INPA cable and software this month so I will post live data. I hope this forum will be able to help me find my problem with my car, here mechanics know how to fix only 320d

Hi guys, my name is Marko and I don't speak German, sorry. But I have a problem with my BMW and I registered on this forum to ask for help.
My vehicle is a BMW 316i 10/2003 with 120,000km on it and I am the second owner. I bought this vehicle in Germany and since then I have a misfire problem that no one can find.
Car is only misfiring on low RPM. From 1,200 RPM to 2,000 RPM (When it's cold it misfires to 3,000 RPM). It's shaking on idle a little bit. After the RPMs go above 2,000 it's not misfiring.

Any help is appreciated
