Hi. Which speed sensor? There is one at each wheel, and these work out road speed and are the abs break speed sensors. Ther is a cam speed/position sensor at the top of the engine. There is also a crank spped sensor that picks up from the rear crank oil seal housing. Regards, Neil

You have a alternator going out if you get the car going pull the + cable off if the car dies right away the alternator is bad . (Ase) cert auto tech

I have a similar problem with mi Jetta 2010, I when the last week to the dealer and they didn't find anything bad, but the problem still hapenning.

Perhaps a leak from a foreign object or a damaged bead. When filling the tire use the manufacturers instructions as found on the door pillar and add 1 PSI for every 500 ft of elevation

Check the fuse. Look in your owners manual for the location of the fuse panel and the location of the fuse the works the wipers.

The code is in the owners manual. If you can't find it stop into a VW dealer. Or simple call a VW dealer.

Yes both the vw and audi have one. If it is one then there is a fault. Is there a stored fault? Do the brake lights work? If the brake lights are not working then I would start at the brake pedal switch.

I THINK U DONT HAVE ONE!!THE CARS SPEED IS RECOGNISED FROM THE ABS SENSORS AS FAR AS I CAN SEE AT MY WIRING DIAGRAMS.WHAT IS UR PROBLEM EXACTLY?

Check for child proof locks in the car many people are not aware that these come with the car. If this is not the problem you may have a seat belt caught in the door you may have to pry it open using a peice of wood and crow bar jus put the flat or crow bar in the crack put the wood on the door so you wont scrach the paint the pry ever so lightly until it opens.good luck.

to remove the hopper you need to remove the bottom pulley then you can remove the bolt. when the pulley is off so should be all the belts, to remove the belt there is a socket on the adjuster put spanner on this and push left the belt will come loose and pull it out of the pulley. same to put it back on.

fuel sensor in the tank may be warn you can test to see if it is that by turning on and off the ignition if the gauge jumps. then it is the sender in the tank. under the carpet in the boot is a cover open this and you are at the tank it has a screw on cap and 4 wire on a plug going to it, remove the wires and the pipes for the pump and push to one side when you do this make sure you use a cloth as fuel will come out, before any work is done further it must be dry from fuel so leave it for awhile till dry. then undo the screw cap, ( dont do on a full tank of fuel) the top comes away a bit and unplug the wire on the other side this will give you more rum to get the sender out , it is clipped in at the top just squeeze the top and pull out, replace with new one and make sure its in place and dont move, this is the hard part now you have to make sure the wires dont get in the way when you have put the cap back on run the wire around the fuel line and up to the fuel top and plug the wires back in and re put the tank back to the way it was, it should be all working now.

have they said were the leak is, as if it is the connector you can replace the seal for the pipe. failing that you will need a replacement, there are plenty on the market you can choose from, or even get one from a breakers yard for a good price. just remember to flush. out all the old brake fluid after you have fitted the replacement there is a kit you can buy that will push the old fluid out. and then put new fluid in. the kit will help you do this to.

the wiring plugs are on both sides at the back in the wiring loom there will be an empty plug no wires come out of it, each side has wiring for indicators left and right brake lights etc and one live wire this can be used for stable power to keep fridge in a caravan working wile you are driving up to maximum 15 amps..

fuel injector or pump relay may have over heated and bunt out they do over time then the magnet cannot move to switch the fuel on or the injectors to work. these are in the engine bay fuse box. also check the fuse in there to as this can blow when the relay goes.

hope you mean the gas tank filler pipe. as would not like to open the gas pump. in the boot you should find a plastic triangle this is for opening the filler cap. if its not there i must of been pulled off and you will need to remover the cover and pull the pin back.( it lock the filler cap). you may need to change this part as they can become unworkable after a time. or could just need a re grease.

check the throttle control box this also is for the cruise control. also check the switch on the brake pedal. if both working it could be a problem with the cruse control unit. you would need ti to be put on an obd reader to find the fault.

no horn relay, but the connector wire for the horn can be a problem, check that ti has not go green connection inside the plug wire if has be careful and clean it out also check the earth wire under the batter plate.
