When it cuts out does it restart up straight away or any engine management lights pop up when it does?
What do you mean tb? throttle body?
Was it a camshaft fault/dephaser fault code that was diagnosed to have the pulley replaced and t-belt?
Customer: replied 2 years ago.
No it wasnt they done the t belt and pulley because of the classic rattle on start up and 3 attempts to start that's now gone however the citing out remains as I'm slowing to a stop

All sorry not oil
Expert:  Robert replied 2 years ago.
If the check injection light is means fault codes will be ideally you would need to find out what those your description of events and the car cutting out at slowdown sounds like classic CKP sensor issue dropping out and thus this can cause the car to cut out on slow down..the only way to know that for sure is to live data test it - plugged in drive the car to see which sensor either crank/cam position is dropping out or not sending back info..have they done a fuel system pressure test just to be sure thats ok and within spec..givin what you've had done already upto now..then as above would be a few other things to have checked out..if not already done of course which you dont mention..I do hope this helps
Customer: replied 2 years ago.
They haven't done a fuel pressure test as I know he did clear all the the codes but this injection one has come back they ran a test and cam sensor had flagged as the only fault it's in now waiting for Renault sensor to be fitted to it I hope it works is the ckp the cam sensor ?
Expert:  Robert replied 2 years ago.
No the cam sensor monitors the camshaft timing - the crank / ckp sensor monitors the crank timing via the flywheel..the ecu uses those to work out engine timing,tdc or positon when to fire the coils/injectors at the right the sensors have to work together or run in sync.if one of those sensors drop out..then the engine wont run or cut out..If they've diagnoses a cam sensor fault..they need to be sure that the crank sensor is ok too..sometimes a faulty cam sensor could mean a fail on the crank sensor..But yes the sensor from dealer would be ideal and hopefully that should sort it..I do hope this helps...Please dont forget to rate one of the answers above..most appreciated..
