Logan Vibration and Low Fuel Economy

My Logan 1.5 DLE has started Vibrating when it was 8 months old and it's NVH went higher by the day. I informed the Service center about it. But they where not able to find any fault.

As being from Nasik. I tapped some resources and Rang some telephones and caught hold of some Engineers from Mahindra. Was in the service center with them full day. They where Not able to test some Parameters. They Deduced that the ECU of my Logan is Faulty. The engineer told me that the ECU has lost some Settings it can neither be reset or reprogrammed or remapped as it is locked by Reno. It is a very costly affair to change the ECU.

Another Thing is We tested the car with another ECU from another car and the car stopped Vibrating and It's NVH came down to a very low level, It was sounding like a new car. The parameter which was not coming up on there computer showed up. The smell of the burnt fuel also changed it was not smelling of unburnt diesel. It took about 30 minutes to Do all the testing.

After that the ECU of my car was put back the NVH again went up the smell of the unburn diesel came back. But the parameters which where not coming up Previously on the laptop came on.

NVH is high cos the Ideling RPM for the car is around 950 and it should be around 810.

Now I am in a fix that the Vehical is around 30 months old and very much out of warranty.

Hope some body can help me

Why tell us this ? Tell the workshop .STAND UP FOR YOUR RIGHTS
One of your cylinders is not getting fuel .So it is a OBC problem this is why it vibrates
3 cylinders are fireing and one is being PULLED around and the one being puuled just shoots the fuel out of the exhaust pipe (What fuel it get

@ martin245 thanks for your thoughtful response.

We checked that also and but the all the cylinders are working fine. They checked the fuel level fuel pressure on all the cylinders. That is why the service center people could not find any fault.

When the ECU of other car was put in my car every thing started running properly.

MY logan is having noisy vibration under from the silencer.It starts wen i switch on the car n even wen the car is in first or second gear it is noisy underneath.How can i overcome this problem?

my logan gle 1.4 is also vibrating a lot and after my mechanic adjust the tappet setting,
