Renault Scenie II - problems after cam belt change?

Had cam belt changed on 5-year-old diesel Scenic. Ran beautifully before. Straight after, made new noises which are getting worse. Also on motorway, accelerating hard, there's a slight pause after putting foot on gas pedal and then car lunges forward. Dealer says there's no problem, and noise is caused by engine mounting (but there was no problem before the cam belt change). Anyone else had this happen? Was it resolved?Renault Scenie II - problems after cam belt change?I had similar problem after cam belt change, bolts had not been tightened correctly resulting in engine seizing up, I then had to have a new engine fitted, so I would suggest going back to whoever fitted cam belt and ask them to check it again.Renault Scenie II - problems after cam belt change?I'd say it sounds like the belt has been put on a tooth out. Go back and tell them this and that if any engine damage occurs you will hold them responsible.Renault Scenie II - problems after cam belt change?well truth is my car has over 300,000 miles still riding with same belt and truth is if it wasnt bad before and it is now then the job wasnt done right and you should take it back and last you shouldnt have gone to a dealer to have it done would have been the highest place and the least likely to get it done right... is why they have auto shops all a round to work on cars they have dealers to sell cars so tak eit back say its not right or go to a better shop and have it check most likely job wasnt done rightRenault Scenie II - problems after cam belt change?I just changed the cam belt on my brothers dci 100 bhp, and the bottom cam belt drive pulley does not have a key way which makes it very easy to get the timing wrong, That could obviously have an effect on the way the engine runs as timing is very critical on modern diesel engines. (Some of the 1.5 dci engines have key ways on all their pulleys, and that makes belt replacement much easier). A good dealer would take the car back and re check the belt timing, and ensure that all the locking pins used during the belt change fit correctly in there retrospective positions.

Scenic's do suffer from engine mounting problems, but if everything was ok prior to belt change then it is more likely the engine mounting is now incorrectly positioned as apposed to being worn out. Also the dealer removed the mounting so if it is worn out they should have noticed it !
