Hi, my 05 Grande Scenic 1.6 (megane) has started to throw up problems in the past 3 wks, a warning light has come up "Check emissions" along with the symbol that looks like an engine since a power failure. It has failed to start - battery completely dead when I put in keycard in, tried both keys but the dash remained blank & car didn't turn over. Car was started using jump leads and ran fine - then 2 days later same again, except this time I couldn't even unlock the doors. We booked into garage but had to jump start it a 3rd time to get it up there...battery was replaced and dignostic check showed nothing, so computer was reset and I got it back...fine until next day - dead as a dodo again. Couldn't unlock doors, no power again. Called AA, new battery checked - minimal drain - can taken back to garage - fault showing on dash again. Electronics checked by mobile auto-electrician but nothing found. Car kept on forecourt for week, started each time that mechanic tried it (daily), so invited to collect it again tho nothing found. But same problems happened again 2 days after collecting it and the mileage counter may have jumped, also discovered window jerky when pushing button for it to lower. Car jumpstarted and taken to auto-electricians in town. Full check found nothing again and confirmed new battery was performing 'perfectly'. Computer / windows re-set. Found it a little heavy to press clutch when starting it to drive home...and it kept cutting out / offering to cut out as I edged out in heavy traffic, but I managed to rev it to keep going or keep re-starting it...but once I got to point of being able to drive more steadily it picked up and was fine. Am now very anxious each time I go out to car - I live in the country and have little baby with me all the time when trying to do other runs for older kids. Consultation with former Renault service manager didn't throw any light on this, he didn't know what prob could be if diagnostic checks didn't identify a fault. ANY ADVICE or help?? Am very nervous of paying even more money to get nowhere, fault still occuring and car unreliable, leaving my kids stranded, or me and baby. The auto-electrician said that renaults were an electronic nightmare since the time of the electronic keycards, which is a worry. I had a renault for 8+ years before and it was great...but also had two company vans which led to lots of problems with Dealer servicing & repairs even under warranty so have cause to doubt Renault's "expertise".

When the cam sensor fails it allows current to flow when the car is switched off. The battery drains overnight and is totally flat in the morning. Change the cam sensor, which is an easy DIY job, and the problem should be solved.

hi i am having same problems has anyone come up with the answer also how many of you at sometime put the wrong fuel in as i did wondered if this has lasting problems

Many electrical probs start with a build up of water in the bulk head just under the windscreen because of blocked drain holes within. Remove wipers and housing below windscreen to get to this and clear holes of silt and leaves.
Or it's the TDC that needs clening

A friend has the same problem, had 'check emissions' light so had it cleared, battery then went dead so he took it off to recharge it. Now car won't start and has 'check handbrake' light on along with service light

Anyone on this forum actually get a fix? I'm the exact same as Lori, and would love some info!
As the so called professional don't have a clue.
cheers,

Im having the same problem now and doing 6 school runs a day with 3 small children I am also panicking at being stranded. Did you find out the solution in the end? Would be very grateful of any advice.

Have got my 2005 renault megane booked into my local garage for same problem. Have replaced the battery & turned off all interior lights, but still the battery is dead every other day & car stalls when i come to a stop at traffic lights or roundabouts!! Will let u know how I get on! In response to jerky electric windows-if you pull switch up (when windows are closed) for a couple of seconds, then this will fix the problem!!! I found that out in the manual, after the car wouldn't start!!!

i have the same proble with Check Emmissions on the dash constantly.

I did have the major one where the battery would be drained in minutes and had to recharge every now and then. i have just today replaced the camshaft Sensor as the diagnostic check came up with this. I now have to take it back and have the system reset.

I also still got the electric windows go up in 1 inch bursts now and then, the loud engine noise at start up which disappears after 2-3 seconds and sounds quiet again.

ive been having the same problems and had 2 coils (out of 4) replaced before this all started happening, i have been to my garage who i may say are very good and they have checked it over and think it may be a lambda sensor ...so my car is booked in ill let you know how it goes lol

kezzie, June 2010

hi, i've got exactly the same problem. check emmision fault since 2 weeks, flat battery repleaced for new one, which the new one were flat next week morning. in addition some problem from time to time with drive through trafficlight - engine stall.
anyone have got any solution in this case ????

witold john, May 2010

our family car was causing only missfire like problems together with check emission warning,took it to my local garage (browns garage in Haywards Heath,they realy are good,and no im not related to them at all!!)anyway trevor there suggested it might be the coil pack,did the computer diagnoses and it was that the coil pack,it was the number 3 coil but he thought it was better to change the whole pack which he did ,since then it is good as gold....in my opinion these engines are good but it is a let down on electronics,it souns like Lori's car suffering from a faulty computer,rather then resetting the computer,i thing replacing it woul solve the problem.
