bad tire

Could be your rear wheel speed sensor(s) not super pricey but it is a BMW. I would replace those as your speedometer is electric not cable.
Average price is $270.00 USD I do believe. If that dosnt fix your problem you may need to replace the wiring as it may have been snagged and broken.

i think you have thrashed the life out of it and now you have a problem with piston rings ,could have a broken top compression ring on this no2 cylinder ,i done the same thing to my astra when i took on a BMW 3 series at some lights last year i beat it away and humiliated the driver but i broke the rings on no3 cylinder

Welcome to the world of BMW's. return the car to the seller. you got a bad one. You got an electrical short draining the battery. Bring a blank check and sign it over to the dealer. They're going to have to run through the entire electrical system to find the short. That work alone is worth more than the a used up 2001 325i.

remove the intake manifold to gain access to it, it's on the driver side.

You need to determine if it losing electrics or fuel. Does it sputter as it dies, or just dead off? Dead off usually means spark circuit has been interrupted. Think of things such as bad coil, crank sensor, ignition module. These items have electrical coils inside, which can develop a crack in a wire which heats as running and fails, then cools and will run again. If it seems fuel related, first check for bad gas cap vent, then use fuel pressure gauge situated so that you can see it while driving and see if pressure drops just before car dies. This could mean bad fuel pump, dirty filter, bad relay.

that's normal when hot, but should't run down the battery. if severly overheats ffnd/fix that problem. the other will probably dissapear . if not excessively hot then the fan heat sensor is faulty....

if you have a bmw 325i 2001 model try this solution:
if you have one key , go on to the next step. if you have more than one key, like two or more than follow this procedure.

step one: unlock the doors with your key and get in and close the doors but do not lock them
step two: put your key into the ignition and turn it but not to start the engine, do this less than 5 seconds

step three: take the key out of the ignition and put it near the shifter. press and hold the unlock button while pressing the lock button 3 times. you have 30 seconds to do this. the doors should lock and unlock automatically signalling that it the key has been reprogrammed. if you have more than one key follow those steps for each one except for step one. remmember you have only 30 seconds for each key. that should help you.

Take it to the dealor

Check the codes

• Disconnect the battery. And recheck , how's the plug ?

Check the codes and check for spark

Get a boost or Try a next key then check for codes or maby your starter is bad

driver footwell towards the left on e46 model later models have it under the glove box it is a white contol module screwed on.

take it to a mechanic to check the timing. if the timing is off then it may run at a idle an a little above but once you rev it up then the timing will truely show an it will run like ****. have you checked your air filter that may be another cause. hope this helps
