SOURCE: 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

SOURCE: how to fit cam belt to renault megane 1.5 dynamique diesel 2004

not difficult with the right equipment ,firstly you will need a special tool to lock the crankshaft in place ,then another special tool than aligns the tdc this goes through the cylinder block at the front right hand side by taking a bolt out in the block thats just in front of the bell housing .The special tools cost an arm and a leg trust me and then the pulley bolt has to be pulled up to 130lbs ,the bottom pulley does not have a keyway so without the right tools its very easy to let the engine turn and clout the valves which breaks the camshaft bearing caps with relative ease .the kit you need can be bought and its kit number AST4390 plus the locking pieces for the flywheel .This is not a weekend mechanic type job ,yes its easy with the right tools but even myself will slacken tensioner and remove the cam before i start so valves cannot catch when i turn engine over on starter with a big bar on the pulley nut ,then change the belt then with assistant holding a snap on heel bar in the flywheel ring gear whilst i hammer the bottom pulley bolt with the air wrench ,then use the 80cm knuckle bar and have a good grunch to make sure its really tight or it WILL TURN and the valves hit and break and imbed themselves in the pistons and smash the cam bearing caps .This is not a job for the faint hearted ,their is a timing mark on the flywheel looking from the top through a elongated hole and TDC is a longer tooth ,the inspection slot is about 3cms down from the crank sensor

Did you put the new cambelt onto the cogs correctly, did you clamp the position of all the pulleys while you removed the old belt and put on the new one? if not, the cam belt will need re-aligning.

Loss of power to renault megane diesel 1.9 dti

biggest cause of loss of power on this model is the accelerator pedal module ,what happens is the car runs ok then just loses power stop and turn it off then restart and it runs ok again for a while ,time between slow downs can vary depending driving conditions.

Renault Megane 2 2005 1.6 16v keeps cutting out when i accelerate, the car will not idle correctly i have been told that its either the cranksensor or the camsensor or the idle air control valve...i...

The idle control for poor idle. The sensors are for spark timing control by the computer-cutting out at acceleration doesn't sound like those sensors are at fault-but if a mechanic told you that, I won't argue. I would have the fuel pressure tested, though, before replacing any other parts.

No accelerating

First you must make an effort to discover if it is a gasoline, electrical or air problem.
