BMW E36 Forum

Hi,

I have a simple question.
Last week I changed the cooler. Started flow, because on the cooler was two small cracks. Everything is okay now. My question is The BC still reports check cooling system. I thought of the BC Check error correction on and off permanently. I had before E46 and I know that E46 errors is all deleted over the diagnostic. It is also necessary for the E36? I have a small BC.

Thank you for all tips.

I take it that the message goes out after about 30 secs ..
You need to bleed the cooling system sometimes you have to do this a few times I given up on mine just check the level the same way most other people do.. (look at the reservoir)

check the sensor it self, i had the same problem i tried to clean it but i (broke it) ended up buying a new one for about $27.99 after that never had a problem also, as davidaln9 said, its very recommenced to take a look at the reservoir

It was a coolant level sensor - 17€

Thank you for coming back and confirming the resolution. We all learn from that
