Thermostat Replacement without Coolant Drain
Got the dreaded P0597 - Thermostat Stuck Open error code a few weeks ago. Unlike other cars, modern BMWs have the sense to design the t-stat to fail open. This prevents your precious engine from going KABOOM in a short time span. A call to my local BMW dealership they quoted me $223 for the t-stat alone plus another obscene labour rate of $300. So…. DIY it is. Picked up a MAHLE unit from Amazon for $90.
The interweb has a few of BMW thermostat change instructions and videos. However only one youtube video pertians N20 on a 528i. And it was a bit grainy. Also I was a bit stingy wanting to minimize draining the fresh (less than a year old) coolant. That required some out of the box planning. That said, if your coolant is old enough, you should just drain it. Be forewarned, this is a messy job. There's no way around it. Tools needed: - 8mm socket wrench - T30 Torx with extension socket - Pliers - Flat head - Nitrile gloves - Big drain pan - Funnel with small hose attached into a bottle (I used to this to capture the inevitable coolant hose splash)
That's about it. |

Got the P0597 code this week just over 80k KM's. I'm also thinking of doing myself after a call to BMW Canada to see if it still may be covered. But I doubt it

I got the p0597 code for my 2013 X1 2.8 x drive. IS it possible that:
A. Coolant leak can cause the code and/or old expired coolant running in the system B. Failed T-Stat/needs replacement c. Possible loose/faulty connection from wire to unit What is common with this vehicle? Has Approx 125k miles. Also has a P0442 small Evap leak, is that most likely an easy fix with a new gas cap? |

Replacing the gas cap would be the easy/cheap fix that I would try first. Not sure how much they cost..... maybe $10-$20? I would buy a new gas gap and install, then clear codes to see if it reappears again.
