Irregular light intensity and starter difficulties in the Renault Kadjar 2017

Weak battery when starting the engine

|

Dim or flickering lights

Hey guys, my Renault Kadjar from 2017 (gasoline, 66727 km mileage) is a bit of a worry right now. The lights are very dark in places when driving and the starter is struggling. Strangely, this is particularly noticeable when the car has been parked overnight. I suspect that the temperature sensor of the vehicle battery is faulty. Have any of you ever had a similar story and how did it develop at the mechanic? My last experience was unfortunately not the best, so I would be grateful for any tips!

Hi buddy, something similar happened to me with my 2015 Renault Captur. Its engine control unit was defective. In fact, the lights were going crazy and the engine was struggling to start, especially after being stationary for a long time, just like yours at the moment. I initially thought it was the battery, but the mechanic then discovered that the engine control unit was causing the problems. The device controls many functions, including the lights. According to the mechanic, this was a serious problem that was not to be taken lightly. But after it was replaced, my car is running like a kitten again. So, ideally you should take it to a garage as soon as possible to avoid more extensive damage. Hope this helps you!

Hey, thanks for the helpful insight! Your experience sounds pretty similar to what I'm going through right now. Do you remember approximately how much the repair cost? And has anything else come up since the ECU was replaced? Would like to go to the garage as prepared as possible. Thank you in advance!

Hey, no problem! Yes, the repair for the defective engine control unit cost me €1000, but it was worth every penny. The car is now running perfectly again! And yes, the vehicle battery temperature sensor was also faulty. The mechanic found it during the check and fixed it straight away, since then the car has been running like clockwork, not a single incident. I'd advise you to have it checked while you're at it. I can't wait to see how it goes, keep us up to date!

Thank you very much for the detailed information! That reassures me a lot. It sounds like a hell of a ride, but as long as the car runs again afterwards, it's probably necessary. I will take your advice to heart and have the car checked as soon as possible and also have the temperature sensor checked. As soon as I have news from the garage, I will of course let you know. Thanks again, buddy!
