I took my car to a Renault dealer and they solved the same problem by replacing the non-standard 4 prong spark plugs that the previous owner had in the car with the standard 2 prong spark plugs Renault recommends. My water pump also needed to be replaced (different issue, and was identified with a mechanical noise). I also proactively changed the fuel and oil filters along with new oil.

You might also want to look at getting the coils tested, as these tend to fail often causing loss of power, and a mechanical noise.

In most situations, it is better to take your car to the approved Renault dealer to check the fault. My experience with using other mechanics to fix faults on the car was less than desirable, and ends up costing more.

My Diesel Golf lacks power and acceleration on hills, can you advise what the problem is?

The problem could probabely be the diesel filter, try replacing it.
If there's no difference thn best would be to service the injector pump and the nozzles.

Scenic 1997 1.6e loses power

judering sounds like brakes ,but iam no doubt wrong it could be a valve allowing air into manifold not working ,loss of power is no doubt caused by the same component,best advice apart from burning it and giving the agincourt salute is take it too dealers as most renaults use a lot of software based programs ,some are readable and some are not ,new ones use encrypted software ,mechanics nightmare these cars ,another pos is the valve control on the throttle ,,,but it would be cheaper in the long run to use the dealer
