2ef7 Map Thermostat Activation Lock Seoccseoof Is the code 2ef7 general to the cooling system and not specific to the water pump or thermostat or coolant sensor? does that mean i have to replace the thermostat and if it doesn’t solve the issue, replace the water pump and the sensor?. It would seem like thermostat has failed. could be the water pump as well. if you are using just regular obd scanner, you most likely will not see a waterpump code if there is one. retrofits: 322, 609, 6fl, 6nr, 6vc, 2tb thank you in advance but my car started throwing this code late last night.
What Is Map Thermostat Activation I have a 07 bmw with a codes 2ef7,2ef4 answered by a verified bmw mechanic. those codes are both for the thermostat, so it likely needs to be replaced, or possibly the temp sensor is bad or there is internal leakage in the rad. You likely have bmw code 2ef7, which points to a map thermostat activation error. this is a very common issue on n51, n52, n54, and n55 engines found in the e90, e60, and e70 models. This code signifies an issue with the map thermostat activation. it may indicate that the thermostat is either stuck open or closed, or that there is an open circuit in the heater control. Bmw code 129202 (or 2ef7) points directly to a fault in the map controlled thermostat. this is a common issue on n52, n54, and n55 engines found in e90 3 series and e60 5 series.

When i clear the fault codes the map thermostat one remains so this leads me to believe this is the main fault and causing the oil pressure to activate? i've changed the timing belt, checked the oil pan and pump, changed the solenoids , changed the hydraulic valve, changed the oil and filter 3 times and changed the oil pressure switch. I replaced both the water pump and thermostat last year with oem parts. recently i hit a puddle with my car (my car is lowered) which did some decent damage to it. i didn't think the puddle would damage the thermostat but a day after driving over hitting the puddle my fault code 2ef7 came on. The dme is msv80 and you're correct the code does mean map thermostat activation. i suppose i was looking to see if op found another solution to the problem other than replacing the tstat, because i have a feeling it might be an electrical issue all together. using inpa, i got some impossible values for the engine and coolant sensors. Scanned codes on snap on zeus: 2f6c: exhaust valve, actuation 2ef7: map thermostat activation 2c77: 02 sensor after catalyst, signal 2ca8: 02 sensor heating after of catalyst, function 2aaf:fuel pump, plausibility ( i was on low fuel for this not sure if that what caused it) 2ef8: map thermostat activation other useful information and questions:.
