The air conditioning compressor of the new Elektro-Mégane can fail during fast charging.
Buying a brand new model inevitably means running the risk of running out of steam, especially when the vehicle marks a technical and technological breakthrough for the manufacturer. The new electric Mégane could hardly escape the mistakes of youth.
A few weeks after the start of delivery, customers are affected by a failure of the air conditioning compressor. Renault was of course aware of the vehicle’s media importance and reacted quickly. Automobile Propre takes stock.
What’s the mistake?
Failures of the air conditioning compressor were identified, which may have made it necessary to replace this part. The number of cases listed is still small, at the time of writing these lines about twenty. The problem was brought to light by the long journeys and intense heat of this summer. Due to the routing of a valve between the battery cooling circuit and the air conditioning circuit, the air conditioning compressor can run under negative pressure and be damaged as a result.
Who is affected?
The error occurs during a quick charge of the vehicle while the air conditioning has been switched off automatically. These are vehicles that are not equipped with a heat pump. The heat pump models have different climate management software that avoids the problem.
What is Renault’s reaction?
The problem gradually became known to the dealers, who were therefore able to provide an explanation to the customers. And it became public. Renault then officially informed its customers that it had “determined a low probability that the air conditioning system was out of order”. And above all tries to limit breakage.

What is the solution ?
Renault states that a “solution will be applied remotely in September”. There is no need to go to the workshop because the update is carried out “over-the-air”.
What to do in the meantime?
When fast charging, care must be taken to keep the air conditioning on. To prevent the air conditioning from switching off automatically after a few minutes, Renault has therefore sent the following method: connect the vehicle, start charging at the terminal, then start the air conditioning!
But be careful, you have to board, close the doors BUT don’t lock them while loading! When the doors are opened/closed, the air conditioner stops after 60 seconds. In addition, if the procedure is followed, the air conditioner will need to be restarted after 40 minutes.
All this lengthy process does not affect the standard top-up.
