Loss of power and thick black smoke? (01 clio 1.5d.. NOT a saxo!)

30th June 2013, 21:57

I know this is a saxo forum... But my dad has problems with his 2001 renault clio 1.5 diesel.

With it still being a 'french car', i thought someone on here could shed some light on the problem.

Most of the time, it drives spot on (very economical) but then he would have a sudden burst of thick, black smoke and loss of power.

It would go on for a while an then be back to normal?

Anyone head my in the right direction (apart from a garage

)

Its the Egr valve mate. Take it out remove the motor then stick it in the dish washer if you have one. The clios are a bastard for this.

Once its removed and cleaned get yourself some dry grease and lube the whole lot up with it then re fit. Mine use to do it every 6 months without fail.

Also in the vid it doesnt show the internal part of the egr valve the rest of it looks like this

It all needs to come out and to be cleaned and lubricated. Also if its a dci 65bhp then you would do some good running a tank of the diesel extra/ diesel excellium with a bottle of forte diesel system cleaner.

Sounds to me like the EGR valve, though dont rule out a trippy MAF sensor.
Both easily fixed.
