Issues with my Clio 200 RS and no idea where to start.



  Renault Clio RS 200
Ive had issues with my clio since purchase around a month ago, I’ll start listing them:

Cooling fan didn’t work to begin with, changed it this saturday and worked after fitting but it stopped again a couple days after.
Battery light comes on and turns back off after 5-10 seconds, got the codes and what not,
Traction control light comes on occasionally on startup and stays on for a while,
Airbag light was on consistently until last night when i drove around with friends in the car,
Scanned the car and these codes showed up (picture listed), only active one is the knock sensor

All sounds like electrical to me but i’m not no expert and I was wondering if there are some electrical weak points on these clios that I should look out for.
Anything is helpful.

Cheers

Autel shows the alternator appears to be working, worth checking it on a multimeter to see if it's erratic.

Check the earth points make sure the main earth are clean and in good condition

How olds the battery? Mk3s weren't as fussy as a MK4 with battery condition but if it's on its way out it's a good place to start.

Ive done a battery test on the autel using the battery tester, and it said that my battery itself was weak, after which I changed the battery to a new Lucas one.

The earth points should be all good considering i’ve had the engine out in the past two weeks, i’ll look more into them though for sure.

The alternator is actually napa so that’s probably the issue haha, i’ll test it under load and see what it’s like.

Do you think the alternator would cause issues with my fan? That’s my main concern, don’t want it to overheat.

As above.

With most of the codes being related to abnormal voltage, i'd start with the alternator and battery.

Do you know how old those codes are by checking the freeze frame data? They could be old.

All codes apart from knock sensor were on startup (started at 192 rpm), but i’m not sure what to make of that.

Flagging loads of codes on start will be due to low voltage. Check all your power and earths are good/tight.

Get a test meter on the alternator when running to check voltage.

Bingo, you've probably missed one! (not taking the piss, ive been there!)

I'm sure there's one down the back of the gearbox somewhere that i missed in between the ABS block and starter motor area.

Does the fan come on when you test it with the Autel/turn the AC on? or is it just not kicking in when you expect it to?

Haha yeah probably worth a check all around.

I couldn’t actually find the test on the autel which was odd but it doesn’t kick in at all for some reason, the fans brand new so it should theoretically be perfectly fine.

Only thing that’s a bit odd is the engine makes a little metal ish bearing ish sound from the belt side when it’s under load from around 2.7k rpm, which i suspected to be the alternator because of the other electricity related issues, do you think that’s potentially anything?

Another thing, I just sat the car in idle for a little while on my drive, and when it got to around that temperature when the fan would kick in the voltage dropped to around 12.3 for a solid 10 seconds and dimmed the lights as if it was sending power to something, after which it sat at 15.4. Alternator acting funny or something else you think?

The napa alternators are meant to be rubbish and means the car doesn’t run well certainly under load. Worth changing for a second hand one.

I did try one in my racecar and quickly binned it off
