False readings somewhere in the middle will give combinations of both symptoms. Figured it was just due for an oil change since the odo was counting down on start. Depending on what year model we are talking about. As far as replacement of it goes, it's very simple. Could be hundreds of things. It was an open t-stat. Depending on your code reader, if you can get live data, look up the coolant temp reading, if it doesn't make sense, or there's no reading, there's your answer.
No error codes since I did that. If the connector is okay, then generally the sensor is at fault. If the fan is switching on, look for accompanying failure codes that could be forcing the fan on. If you have a scan tool with live data, check the engine temperature when the engine is cold, it should be close to outside temperature. The vast majority of the time, they would be right.
Were is the air temperature sensor located also what is the process for checking the operation of the air temperature sensor and fans. So you should chech it on our car models. Drive a car for 10 minutes and check the engine temperature again, it should be close to 180-220°F or 82-105°C. In other words, there is a problem with the engine operating temperature not being reached within a certain amount of time. Generally speaking, the hose should be barely warm until the thermostat opens. Another symptom in vehicles that have a gauge for water temperature is that the temperature will remain low.
Thermostats are designed to fail open so that the engine is still protected in case of a failure, but this would result in the engine being slow to reach temperature. Mine is a all-wheel drive while 325i is rear wheel drive. I had the same problem about two months back on my 330. The sensor should read close to ambient temperature at this time. No issues since doing the job, roughly 2000 miles ago. These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage. Your gas mileage will also be terrible, so you should try and fix it as soon as you can.
In terms of handling, it is very great at cornering as suspension setting is good. It will work for adults though. Also replaced the t-stat housing while I was in there. Pretty unlikely that it's a faulty assembly, but I'd start with that. I can tell that this work will take me at least 4-5 hours of work, being someone a newbie on this kinda work. When you take the old one off, look at the shaft in the middle. It comes with a 16inch wheel and that's good enough for your daily driving needs.
Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift. My gas price is lower than his even I was using premium fuel. If the hose gets hot all of sudden like it should, then the next thing to check is the reading you are getting from the coolant temperature sensor. In the past the Service light was related to a service interval. I know what is all about. By holding the special tool in the left hand and putting the wrench in your right hand, push them together. It's built into the housing with the thermostat that you replaced already.
You should also check that the spark plug gap is set properly. Pay attention to if the fan runs during this test, and if it turns on intermittently, what is the impact on coolant temperature. Mine is an auto, and I had to manufacture a tool to hold the fan clutch in order to back the fan nut off. In most cases, whenever the code P0128 is present, the thermostat is replaced. So you see I am almost a sec slower. Both times, a new thermostat fixed the P0128 code.
One is on the lower hose, and the other most likely failing one is on the block along with the overhaul. Read your codes out, is your vehicle running ok? Today I took the vehicle to O'Reilly Auto Parts and they put a code reader on it. I recently replaced the temperature sensor because it was leaking. After I replaced the sensor I started the vehicle and the light went off briefly but came back on. The vehicle would then be very difficult to start and drive when cold until completely warmed up.
