Smokey Renault Scenic Diesel - Tonyman
2001 Renault Scenic 1.9 Diesel, 50000 miles, apparently running OK but smokes a lot on hard acceleration. Is this normal for this engine? Will any petrol additive work? Are there any other cures?

Has the air filter been changed recently? Petrol additives won't help, but diesel ones might. It may just need an 'Italian Tune Up' a good thrashing in other words.

Change the oil,filter,and air filter as John says give it a good long thrashing if it still does it then it could be injectors on the way out .

If an Italian Tune up doesn't work, go to your friendly Renault dealer and ask for some 'Reducteur de fume'. Will cost you about £14 but a lot cheaper than new injectors.
