How can i remover a damper pully nut from my 2001 BMW 320 Diesel, can anyone help me please

What tool are you using to read the codes? Which country are you in?

try using the impact gun again only this time set it on do up tension as the bolt may be a left hand thread lock bolt /nut.

I would have the injection pump tested for porper function. Since we do not have diesel BMW's in the USA that is about all I can suggest. Sorry

to start you will need a 32 mm wrench and long narrow flathead to remove the fan blade,looking at the motor is releases the the right,spin off the blade and remove along with fan shroud for accesabilty,loosten the 4 10mm nuts on the water pump pully before removing the belt as bekt will hold tension but dont fully remove the bolts just release a couple of turnsuse a 16mm socket or a 8mm hex key to remove the alternator w/p belt,no need to remove fully,there will be either a hex head for a socket on the belt tensioner and if not pop off the plastic cover on the front of the pully to reveal a hex key bolt, once the belt is off remove the 4 w/p pully bolts, if the pully doesnt come right off lubricate with penetrating oil and tap lightly with a hammer while spinning it slowly and it will release,now that the pully is removed you can now see 4 10mm nuts hold on the w/p.remove the nuts and spray aroung the pump with wd40,you can try to pull and wiggle on the pump, if it doesnt come out you must obtain 2 bolts that will fit to the sides of the pump, you will see two thread holes that are empty,when you thread a bolt through with even tension on l and r sides the w/p will begin to pull away from the block. Once the pump is out lubricate the new pumps o ring with coolant to help slide it in, push in the new pump and re assemble in reverse,to fill the cooling system open the phillips screw on the overflow expansion tank,fill system with a 50=50 mixture of coolant until coolant comes through the bleeder screw with no bullbles,close the blleder screw and run the car at idle with the windsheild defroster on and heat at full. monitor the coolant level until it has sufficient flow and close cap,you can have a friend rev the engine to about 2000 rpm for this, road test the car and allow to cool, re check for leaks and fluid level when cold again to ensure repairs are correct

If you removed the camshaft cover, you should probably replace the gasket or at a minimum insure that all bolts are torqued to OEM specification.

Look here for instructions and pictures for the oil change.

The fuel filter is located on the bottom of the car, not sure which side, under a shield. Look here for pics and instructions.

Hope this helps!

Hi, the fog lamp should have a cover surounding it. this will just pull off then you will see a 8mm screw bolt, remove this and the fog lamp should then be able to be removed.

Blower relay is behind the glove box. You have to remove the glove box, you'll see three relays in a row it should be the one all the way to the left.

this sounds like the heater resistor is faulty and requires to be replaced
