Engine cuts out when approaching a roundabout or junction, when slowing and clutch is down. Changed the speed sensor a few months ago which we thought had worked, problem came back yesturday

Have the clutch checked to make sure it is properly adjusted it may not be disengaging totally.

check wires to plugs and gas filter,if that fails do a tune up.

Faults like this can rarely be solved in this manner as there are many things it could be, plus you need specialised diagnostic equipment. Take it to a renault repairer and get them to look at it.

The first thing to do is have the fault codes read to determine which sensor/s are playing up. Check the condition of the cat converter as it may be broken and blocking up the exhaust system

There are times, such as approaching a roundabout, turning into a junction or coming down a hill when I have slowed down and then want to accelerate away again. When I put my foot on the accelerator, the car acts as though it has gone into neutral or that the clutch is slipping. I have tried watching the display to see what gear it is in when it does this, but can't see a pattern.

I have tried driving in ES mode but it made it worse.

Also, when in automatic mode, I sometimes get a bleeping noise at low speed but the manual says this happens in manual mode!

Has anyone else had these problems and found a way round them or do you think I should take the car back? I have done 2500 miles.

my 2003 bmw 316ti se id doing exactly same as this but also a rough idle when started from cold. it cuts out at most junctions etc when putting on breaks and pushing in clutch, starts no problem. it drives beautifully when out of town etc no overheating etc. please help. i just had a mechanic on it for 5 hours with no solution.

there was a fault came up when plugged into diagnostics (MAF sensor) but checked maf sensor and it is a new one so erased fault code and hasnt came back so assuming this wasnt erased when new part put in.

84 uses a carburetor I believe. I had this problem with an 86 corolla with a 4ac carb'd engine. Somebody noted that it may be my floats in the carb, could have filled with fuel just enough so that they dont fill the bowl with an adequate amount of fuel to sustain around a corner or hard braking.

Its probably most definitely fuel related.

clutch slipping change the clutch

could be a tp sensor.

i would start by cleaning out the throttle body. they collect soot and not have to be a lot either for it to mess up the idle speed, i had trhis on mine soon as i dipped the clutch to slow down the rpm dropped to about 400 to stall, i cleaned throttle body out ( taking air intake off and wipe round inside and the butterfly will be enough) and now it idles and the rpm dont drop below 900
