Renault troubleshooting - Cars & Trucks

It sounds like you have an electrical issue with your Renault Megane. If the problem occurs when you turn on the headlights, wipers, or power windows, it's possible that the additional electrical load is causing a drop in the voltage supplied to the engine, resulting in a temporary loss of power.
Here are a few things you can check to troubleshoot the problem:

1. Check the alternator belt for proper tension and condition. A loose belt could result in an alternator that's not functioning correctly, causing a drop in voltage.
2. Check the alternator's charging system for any signs of damage or wear. If the alternator is not charging the battery properly, it could cause the voltage to drop when additional electrical load is added.
3. Inspect the electrical connections and wiring, looking for any loose or corroded connections. If any are found, clean them and tighten them as necessary.
4. If the issue is still not resolved, it may be necessary to have the vehicle diagnosed by a professional mechanic who has experience with Renault vehicles. They will have the proper equipment to diagnose the issue and make the necessary repairs.

I hope these tips help you resolve the issue with your Renault Megane. If you need further assistance, feel free to ask.

no not the dreaded renault ,best advice is to trade it in quick ,This vehicle has electric power steering located under the dash ,Now what happens is that some little unskilled youknowhat in kwikfit or wherever has realigned the tracking so the steering wheel is not level as they only adjusted one track rod end ,this upsets the software on the power steering motor ,this causes the unit to fail which means a reconditioned unit about 600euros but it can only be fitted in a renault garage as they are the only people with the software to reset the unit after it has been fitted ,no re-programmed then it will go wrong within 500kms .go and get a ford focus or a VW /skoda ,never no problems with these cars but this make are hell for us mechanics .try changing the clutch ?? its quicker and easier to lift the g/box and engine out in one
