clean connection at the horns.

The most likely cause of this is the fan not kicking on... and the best place to start looking is the fuse for the rad fan (under the dash). If this is good check radiator thermo-switch... Observe the engine as it comes up to operating temp... if the fan does not kick on by about 200 degrees, disconnect the terminals at the switch and connect them together briefly. If the fan comes on then the switch is faulty, if not then suspect the cooling fan relay. If the fan runs normally but vehicle still overheats, the next thing to check is the T-stat. Feel the upper hose when at operating temp... it should be warm... if not remove the T-stat and reassemble... if the problem goes away it was your T-stat, if not it is either a bad pump, or a restricted (clogged) radiator. If the pump is not noisy or weeping coolant, it's probably OK... Hope this helps...;-)

Hi if you are getting a 1 amp drain with everything switched off thats too much the maximum drain should be no more than 50 miliamps try pulling fuses one at a time to check which circuit is affected  if no joy disconnect alternator cables or plug (not with engine running!) tell me if this helps

Get the Haynes manual for a step by step. Otherwise it's a pain in the but to try to explain each step.

Replacing brakes will not shut the abs light off. You have either a bad sensor or accumulated dirt on a sensor. There's a sensor for each wheel so you have to either pull a code or visually see which sensor is bad, craced, chiped, etc, then change. As for the CE light, go to auto zone and they'll hook it up and tell you why it's on. You have to use a scanner to find out.

what kind of car first of all...and I would guess u are gonna need something in metric since most new cars are metric sizes. if metric doesn't seem to fit then try american sizes..and just to make sure in case a ratchet and socket can't do it ..then a box wrench or open end wrench..both metric of course..

When the ABS light comes on and stays on there is an issue with the Anti-lock Brake System. As long as the light is on you do not have ABS and to turn the light off you need to have the system repaired.

These are not much different from most modern disc brake systems. Once the wheel is off, you will find the caliper assembly is held on with guide pins that screw into place. Little spring clips hold the pads to the caliper. If you do one side at a time you can reference the other to make sure you get it back together right. Be sure to unhook any speed and wear sensors before pulling the caliper off. Use a coat hanger or other wire to suspend the caliper. (not good to hang by the hose) Take the cap off the brake master and compress the brake pistons with a C clamp before you try to put the new pads in place. If the master overflows you will want some rags there to catch it. Brake fluid and paint don't get along very well. To do the job right, you need a dial caliper to check the thickness of the rotors. The minimum thickness is stamped into the hubs on most VWs. If there are scores or lines worn into the rotor they need to be removed and machined. If not, you may be able to remove the glaze from the rotors with some fine sandpaper and lots of elbow grease. ( I always take mine in for machining as it also ensures any warping is taken care of.) On vehicles with 4 wheel discs it is recomended to do all 4 at the same time, but NEVER replace in less than pairs. (front or rear) Another safety note, don't breath the black dust. It's carcinogenic.

Yes it is that easy. It should be a 4 pin connector located on the transmission side of the engine head in a plastic flange. Best is to wait for the engine to be cold. Unscew the radiator cap to relieve pressure but screw it right back on. On the 2.0L engines when you unclip the coolant sensor little or not coolant loss will happen if you do this. Just unplug it, pull out the clip, pull out the sensor, and the seal which sometimes stays stuck. Install the new sensor with a new seal lubricated with some coolant, make sure it's well seated and reinstall the clip. The sensor is well seated if the clip fits right over the top, just make sure both sides clipped into position. Replug it fill the coolant with VW original coolant mixed 50-50 with water if needed and done. If you have a fault you might need a scanner to erase the check engine or fault in the cluster.

What's the reason for changing it? Eratic temperature readings?

need more info, do you mean on the dash or the controller, How do you know its not functioning? There are 2 sensors on the fox one is on the radiator and other is on the engine check to see if it has 2 0r 3 conections when replacing Im a wiz at foxes Ive had a den of them

I've done this job several times using a bench vise and an old bearing to press out the bad one. Not an easy job, easy to ruin the new bearing by not pressing the new one in straight. Most shops will be able to press the old and new for few dollars. Oh yeah, there is an internal Circlip that has to be removed first, a job in itself....

have a compression test done on the engine to check for gasket and cracks.. have a coolant system pressure test done to check for coolant system problems . check cooling fans are operational. Run fault codes to determine for faulty sensor or relay.
