Turning off the Service Engine Soon Light

[Haywood Jablomi]

The SES light in my e46 is on. I had the code checked out, and it was a low coolant temperature. I want to reset the light to see if it comes back on. Does anyone know if this can be done without a code reader or other tool ?

Absolutely, Auto Zone, Murrays, Advance Auto Zone and all those other shops got the code reader.

Better yet, you can buy one from them for about $75. I have one myself and it's easy to use.

After changing my Cam Shaft sensors, my "Service Engine Soon" light wouldn't go off. I bought the code reader and did it myself.

It's important to note that the (Low coolant) wouldn't make this light to come on. I think you have other issues buddy.

You missed the key part of the question, "without a code reader..."

No, no...it was "Low Coolant Temperature" that the code reader sent back. I went to AutoZone, and they read the codes. That was the only one. They also said that they could (would) not turn off the SES light.

So, I guess there is no way to do this without a code reader ?

That is correct. You need a scanner, the best one is the Peake Research reader. It reads ALL BMW codes, not just the generic codes. It also can be used to reset the Oil Change/Service Due light.
