Engine Light & low coolant temp

So Maisey’s Check engine light popped on the other day and I brought it to the local auto parts store to have them read the code. The electronic tester showed a low signal at the coolant temp sensor. 95k on this 2010 justa Clubbie. A few years back The thermostat housing cracked and has it replaced. Beside replacing the coolant temp sensor, is there anything else I should check out?

Was the code P0117 or P0128? If P0117 you can get a new temp sensor at Rock Auto for $5.80 + shipping; it's easy to change. If you have P0128 you need a new thermostat it's sticking.

I did not get the code on Saturday so I will need to return today for a rescan. I found where the temp sensor is located and looks like an easy fix. They want $39.00 for the sensor. That’s a big difference.

Now I have to see where the thermostat is located. Hoping that is fairly easy as well.

I did check the coolant level and it did appear a little low so I topped it off.

i need to drive 300 miles tomorrow to upstate. Will I be safe to drive her?
There is no temp gauge so I can’t tell how cold or hot the engine is running.

Thanks

Only slightly off topic, but a scan gauge will solve the lack of info part of your concern. You can pick one up when you go back to the parts store and scan yourself.

The Scan Gauge will also allow you to monitor engine temperature.

Hard to say if it's safe to drive. Rescanning won't do you any good unless the check engine light is on. I'm speaking of DME faults only.

Well the check engine light is still on so I should be able to get them to rescan and get the code.

I checked my records and see that I had the Thermostat housing replaced just over two years ago and only 14,000 miles.

Hoping it is the sensor and not the thermostat since you tube showed the housing replacement and looks like a royal PITA.

The only problem I have with getting the codes scanned at a parts store is that they cannot read all of the codes. There are some BMW proprietary codes that their scan tools will not see (I know from experience), so getting them read at a shop that works on BMW/MINI is a good idea too, you should be able to find one that will do it for no charge.
The thermostat can be a PITA if you let it, lol. They really aren’t too bad to replace, just make sure you have the water pipe that runs between the thermostat and water pump, it will likely be brittle and will usually break when you remove the thermostat.
A hose clamp tool for the spring type hose clamps is a definite help, for knuckles and sanity!


Something like this.

Craven Speed makes a great mount for the scan gauge, and then you can watch oil and water temp in real time.
