Safrane 2012 - Technical Fault

[Peterkk]

Does anyone a garage who can diagnose technical faults for Renault Safrane 2012 Model in Dubai, Sharjah or Ajman. I have attached the faults from the diagnostic tool. 

Please I have taken to two garages who mentioned they do know the issue and had to tow it to these garages and has not been able to diagnose it. I feel its something technical and not something mechnical. Correct me if I am wrong.

Hi @Peterkk

That's a serious list of errors, but to me they all point in the same direction: Low or no Voltage being supplied to the various components of the car.

My first recommendations:

1. Check the battery voltage and specifically the connection terminals.

2. Do a thorough check of all grounding points. Negative terminal of the battery should be connected to the chassis properly, but there are other grounding wires that will connect to the chassis body. Inspect engine bay and underneath for any loose grounding wires.

Some other questions:

1. Did this occur suddenly? Was the car involved in an accident, flooding, or what is the history of the car that brought you to this problem (did you purchase it recently for example?)

2. A typical "mechanical mechanic" won't be able to troubleshoot this. You need to either take it to a Renault dealer or someone who is used to dealing with French cars. A good car diagnostic shop could also do it, but they might not want to touch it because a Renault Safrane is quite rare in this country.

If this problem suddenly appeared, then i am inclined to believe there is just an issue of loose grounding or battery terminals. A more worst case scenario is your car ECU/ECM that failed (as this unit controls most of the car's electronics). It does not happen often, but it is possible. If there has been water damage or something of that sort, then it becomes definitely a possibility.

I recently encountered weird behavior in my wife's Trailblazer, from the check engine light to the car not cranking.

First doubt, change the battery as it was 4 months old and in warranty.

A week later same issue, so I opened both terminals and cleaned with sandpaper for firm contact and that resolved the issue, so far.

I agree with Fredy, make sure that the battery, terminals and grounding are 100% firm, then only dig deeper after that.

I agree with both Freddy and Gaurav, VWs have a similar response when the battery is dying - the instrument cluster lights up like a christmas tree. if the battery was recently replaced, test the alternator, it could be faulty and not providing enough charge for the vehicle. use a multimeter and check the battery voltage at rest (key off), if the voltage is less than 12.4v consider getting the battery checked/replaced. then to test the alternator, check the battery voltage while the car is at idle, and turn the lights on - you want to see a V of 13.5-14.7V. Any charging fault will trigger F00316 and the whole cascade, so rule this out before digging deeper.

Agree with JC_E, any Autopro at ENOC can check both within 5-10 minutes of testing.

Not only VW, but I rem seeing so many unusual faults with Porsche, Range Rover and Ford when battery isn't healthy.

I had few same lights on Yukon, changed negative wire(which was very tired) - all disappeared immediately
