What could be the cause of my engine's loss of power?
I own a Renault Kadjar Dynamique Nav DCI with a 1461cc engine on a F plate. It is in what I believe is known as Limp Mode. There are 2 warning lights showing...'check injection' and 'check anti-pollution system'. My local garage has changed the oil and filter done a DPF regeneration and checked the working of the sensors. The garage can turn off the warning lights but they very soon reappear.
The car is underpowered and struggles on inclines....it seems that the turbo does not want to engage. The cost of a new turbo is likely to be something approaching £1000 and so I do not want to spend that sort of money if that is not a guaranteed solution. I wonder if anyone has come across a similar issue with a Renault diesel and if so how they were able to solve the problem.

Although a blocked DPF is one possible cause of the problems it may be that there are other faults which are contributing to your issues. We would suggest trying a local independent Renault specialist who may be able to properly diagnose the issue and offer a solution, as replacing the turbo would be the most expensive outcome.
