NO.
The EGR cooler on the M57 has a temperature sensor and an engine coolant loop. However, the cooler does not have a thermostat to control coolant flow. https://f15.bimmerpost.com/forums/at...mentid=1235091 |

Interesting. I keep getting fault P2457 Exhaust Gas Recirculation (EGR) Cooling System Performance. My engine thermostat was broken i replaced it and my EGR cooler was seeping coolant from the welds so i also replaced that. I can't think of anything else that would cause the "EGR cooling system performance" fault code.

M57 does have a EGR thermostat. 25d and 30d definitely does, but with 35d it seems like some do, others don't.
Market differences? I have found engine bay pics of 35d cars WITH the thermostat, and 35d cars WITHOUT the thermostat. Here is one with the thermostat (red ring). Ignore the yellow line. When I check RealOEM with the VIN of my car, it shows up with partnumber.

Yeah, maybe a proper BMW diagnostic tool can be more helpful. Hope you figure it out

Big possibility and i think the X5 M57 might have the EGR cooler thermostat. Wish i could just D-E-L-E-T-E everything, but i can't deal with the emissions inspection headache every 2 years in California.

Thank you. I'm starting to think i possibly have carbon build up. Most likely going to order a new intake manifold to replace and try to clean out the valves.

I can't imagine carbon build up would cause a coolant issue.

My thermostat was replaced at the same time as the EGR cooler because the temperatures weren't going up and I found the thermostat spring broken when I removed it. My EGR cooler was leaking coolant from the welds that appeared to crack so I replaced it at the same time. My coolant temperature is around 180-190F if I recall correctly checking with my Carly app.

I also wonder if the egr EUV being bad has anything to do with the cooling performance of the egr cooler.

I have a brand new intake manifold on its way. I'm going to carbon clean the valves, replaced EGR valve and the intake manifold and see what direction it leads me after.
