battery good?? maybe ignition switch failure or fuse blown

drive it to your local dealer and have them fix it

it probably will be

This unit is located in the engine interconnection unit, below the Protection and Commutation Unit

check you battery

I know its an obvious question but have you checked the fuses? Always check the simple stuff first, It usually saves you money! The fuse box you need is behind a drop down trim panel, at knee height, below the steering wheel. Try this website. https://fusecheck.com/renault/renault-master-1997-2003-fuse-diagram I think it is Fuse 4 (15A).

Most European cars have an inertia switch and location details will be found in the vehicle handbook - or give the dealer a call.

There is an assortment of codes that on the face of things are only loosely connected, though it is unlikely when so many codes appear at once they wouldn't have a common cause and the possibility of an ECU problem should not be overlooked. The trouble is the codes are not only mostly manufacturer specific, Renault don't help matters by making some of them model specific - different meanings depending on model. You really need another code read and scan with dealer level diagnostic equipment where the model and vin can be entered and each code is displayed with the proper description of the related fault. There are few faults that will stop an engine or prevent it starting, though the Renault immobiliser system is renown for suffering from amnesia and it would be wise to check it is being disarmed as well as carrying out some physical checks that would be usual in the case of a non-start.

the key has lost its code. open the doors manually and use the central locking button inside the car. hold it down and keep pressing your key fob. this should re code the key

We had this problem recently on a 59 plate Mk3 megane we initially changed the hazard light switch inside the car after reading on a forum but we were still presented with the problem. At the same time the horn was sounding very worn and eventually stopped working so we purchased a secondhand one off eBay fitted it. At first hazards still come on everytime we started the car but over a couple of weeks the got less and less and now they don’t come on when car is started only when you press the button inside the car so I’m thinking the horn may of had rain get into it overtime and now it’s probably dried out

Depends on what is happening when you try to start it. If the engine will not turn over, the problem will probably be in the power feed to the starting motor (e.g. blown fuse, fusible link or starting motor solenoid) - easy to check with a multimeter. It could be the security system - I would check for trouble codes with a code reader.

Hi. Get a can of DW40. Spray it all over the cap and inside where the key goes, leave for 10 or 15 mins and then try and open it. Good luck.

renault scenic 1600 -- year 2004 -- runs ok but will not idle checked throttle pedal resistances all ok any sugestions?

The colour smoke an engine produces gives a good idea of the fault: - Black/dark grey smoke is partially burned fuel caused by the right amount of fuel being injected badly or by a small excess of fuel. Blue/blue-grey smoke is burning engine oil. White smoke is either steam (usually from coolant ingress) or massive amounts of unburned fuel. A few possible causes of the latter is strangled exhaust, one or more injectors stuck open or a damaged injector (broken nozzle). If there is no coolant loss I suggest you remove the fuel injectors for testing.

Could be abs target to and fault with abs pickups. Must run a diagnostic test to narrow search

You must pull the radio and look on the back

Check brake pedal switch

I have the code for my car but cannot get the other code that is needed without paying for it.

It completely depends what other underlying issues there are. But there are a few things you can check... Is the steering wheel shaking as well? If so it could be a wheel balancing issue or bearings, or something else steering related. If the steering wheel isn't shaking it could be your engine mounts, lack of oil, worn bearings, problems with the driveshaft. The Haynes manual for Renault Meganes are a good start, at the back of the book it has all of the fault finding things you can do. Almost all of what I have suggested will need to be checked by a good mechanic.
