An engine control module (ECM) is a computer that controls various engine functions in a vehicle. It receives input from sensors throughout the vehicle and uses this information to control the fuel injection system, ignition system, and other engine functions. If you are considering replacing the engine control module in your car, it is important to make sure that this is the correct repair for the problem you are experiencing. The ECM can be a costly part to replace, and replacing it without properly diagnosing the problem first can be a waste of money if it does not fix the issue. If you are unsure about whether the engine control module is the cause of the problem you are experiencing, I recommend taking your car to a mechanic for a diagnostic test. They will be able to determine the cause of the problem and advise you on the best course of action.

I'm sorry to hear about the noise your car is making. It's difficult to diagnose a problem without hearing the noise or being able to see the car in person, but I'll do my best to help. It's possible that the noise you're hearing could be related to the transmission work that was recently performed on your car. It's also possible that the noise could be caused by a problem with another system in your car, such as the engine or exhaust. To properly diagnose the problem, I recommend taking your car to a mechanic as soon as possible. They will be able to inspect the car and identify the cause of the noise. In the meantime, try to pay attention to any other symptoms or changes in the way your car is running, as this may help the mechanic to identify the problem.

Im guessing you tried to bypass the key in the ignition/steering column. This is ok unless the actual problem was in the TDM (theft deterrent module) In this case, the 2 wire bypass does nothing. There is another way to bypass this. Check out this link for tons of info and some DO IT YOURSELF options. Ive done several key bypasses and tons of full bypasses. They both work well, it just depends on what part is failing. I think you need the full bypass to eliminate that TDM.

If it works only in the max position, the resistor thermal fuse has gone, a common problem in Passats. Napkin sell for 50p. If it also plays up on maximum then it could be a faulty switch or wiring.

if no codes fuel pump , fuel pump relay,,fuel filter,,====cat converter clogging egr valve carboned up ---these are some problems that sometimes will stall and allow vehicle to restart with out setting off a code

Yes

You will need to replace the crank angle/position sensor near the crank pulley. A photo of the sensor is attached. The sensors wear out due to heat and cold cycles and internal corrosion. MasterPro Ignition - Crankshaft Position Sensor Oreilly's Auto Parts part number is: Line: MPI ' Part # 2-96054

Do you know what a O2 sensor looks like ? It's on the exhaust pipe .

CAN ONLY BE REPLACED.

Well code 171 means the computer thinks the fuel mixture is too lean on bank one. Bank one is the side with cylinder one. The problem could be low fuel pressure, or a faulty O2 sensor among other things.

This is a code for cylinder #6 misfire. Most likely a bad spark plug or ignition wire for that cylinder ( most common repair ). There are various other reasons for a cylinder misfire as well.

A heater core replacement on any vehicle is a very hard job. It would most likely involve taking the whole dash out of the car just to reach the heater and then you would have to open the heater box just to get to the heater core....If you have never done it before I would take the car to a service or repair center of your choice (it doesn't have to be a dealer). The money you spend will give you peace of mind because the job will be done correctly and if it gives you trouble, you have a warranty to fall back on. Much good luck

blue to gray and red to white,black to green

you have a rod going out on the car i wouldnt drive it too far

that could be transmission issue/ front end issue/ with out driving the vehicle hard to say. my 88 had overdrive shudder going up hill transmission need a rebuild. that all i got with out driving the veh srry. when trying to figure out what going on with the veh you need to isolate the cause of the vibration , front. rear of the veh.put the veh on jack stand and drive it see if you can figure were that vibration is comeing from

The sensor in the seatbelt is definatly not working, Sounds like an expensive repair for just a chime,
as a joke I would find the chime and unhook it. But seriously you might be able to find the wiring under the seat for the seatbelt and unplug it depending on the year but after 20 minutes of research all seatbelt replacements ive found say they come without electronic sensor anyway.
Good luck and hope I helped you out some....
I tried my best!
