cam sensor would not stop the engine turning over as the sensor does not work until it turns over.
what is the red light on the dials doing when it won't start and if the problem happens when the engine is still warm does the engine temp gauge work or does it look like it's not powering up.

have you checked all the wiring. ifi remember it's a flat ribbon and runs up into the roof liner and comes down the passenger side windscreen pillar and behind the glove box.
worth checking it's plugged in behind glove box incase someone has removed it to stop a warning message appearing

when you say cocked to the right i presume you mean when driving in a straight line you steering wheel is sitting of centre.
the airbag system has most likely detected the jerk from the ball joint popping and logged it in it's ecu. this should just reset but will need plugged in to a computer.

three things that are guaranteed in your life are Taxes, Death and that your megane will break

when the new sensor was fitted did you also fit the new jelly seal that sticks to the screen as with out this the sensor does not detect anything and they can not be reused so that could also be part of the problem if someone before you has removed the sensor and just put it back on using the old se...

i used tamar electronics there based in devon but do a 24 hour turn around on posted items. mine cost 170 quid and thats including posting it back to you. they have a website but my ecu was not in the renault section it was in the pug and ford section and they list common failings for each car BOSCH...

car starting first time all the time.
cheers for all the input

thats my ecu been repaired and just awaiting it arrival. problem was the chip which contains the vehicle software had started to break down and needed to be replaced. they scanned my software from my old chip and put it into the new chip so it won't need recoded and the security code will still matc...

check the headlamp adjuster is fitted into the back of the headlamp properly and that the ball and socket inside the headlight are installed correctly and the bouncing you describe means the motor has run out of manual adjustment. my bet is that the ball on the end of the motor is against the socket...

must be a very clever ecu (when it works) as on a 500 mile journey it returned 54mpg which is better then i hoped for.

thats great cheers,
just found out airbag system will be fine as airbag ecu is coded to the airbags and not the uch,

the adjustment you need is where the hood actually bolts on to the car body right at the back and are very hard to get too.
you could try with the roof just open putting pressure on it to push it in the direction you need. but be careful not to break anything

thinking of doing a ecu swop on my 1.9 dci because of ecu faults. the kit i'm thinking of buying contains ecu, uch, keycard, steering lock. does anyone know if the dash clocks are coded into the ush as something has to log the vehicles mileage and i presume thats the uch and the clocks so i presume ...

on my 1.9dci i unplugged the maf sensor and it made no difference so i took it for a drive with it still unplugged and no warning light or engine symbols were displayed and it drove just the same as when it's plugged in. and it normaly drives fine. could anyone else with the same engine unplug there...

sounds like you have quite alot of free play on a steering or suspension component. at slow speeds it would not show up and at high speeds the wheels are kept under control by rotational force. in between these speeds it will travel thou the car as the wheels basicly wobble around trying to centrali...
