The car overheated last night, I want to disable auto code clear. I'm about to go take a look, but the car started fine this morning. I did notice that I couldn't see any coolant in the recovery tank. But see no leaks. Thanks.

I added about a 1/3 gallon and that looks to have cured it! Not sure it got a little low, though.

when coolant overheats the pressure release in the cap opens. It probably came out of the cap. You over heated because you need a new water pump.

Dealer just found a leak in my expansion tank today. Might be something to check out.

Do these water pumps fail all at once, or start failing intermittently? I can find no evidence of leakage anywhere.

I have a few months left on warranty.

Can go either way, with or without codes and with or without warning.

why are you still running autoclear ? it is such a bad idea.....

[AirbusPilot]

I didn't even know I had it. Would like to know how to disable it.

have you not heard ??

the N55 DP FIX ? the io2v3.0 catsim ?

allows autoclear off, and no codes with a catless dp setup.....

its all over the place!!!!

Fwiw, my auto clear ALWAYS goes back to showing it turned on in the menu. It's like it doesn't save the last position. Has anyone else seen this?

Took the car to the dealer. I'm not going to gamble on this.

Would like to know the results of the visit to your Dealer. My expansion tank split at the seam and only leaked intermittently. Never overheated but I saw the evidence and tracked it down, from what I have read it's somewhat common.

I feel like my water pump is a ticking time bomb.

The service guys seemed a little surprised it could be the water pump with only 32k miles. We'll see what he comes up with.

The service rep said they found no codes relating to an engine overheat, but a code that said the battery was bad, so they replaced that. He stated it could have been a error message created by the bad battery voltage.

My water pump went at around 40k. There were a few signs.. coolant level was low (but not extremely low), engine overheat minor came up on iDrive. The next day it failed and showed the same message but followed by a critical failure telling me to pull over and stop immediately.

Had it towed to the dealer, replaced the pump under CPO.

Btw- even with autoclear on it will show a check engine light that WILL be visible, but it will reset itself and disappear. The menu to disable autoclear is 1>4.

Thanks!
