Starter Nothing happens when I turn the key. Where is the starter located?

Check to see if power is getting to the starter. Locate the starter and while someone is turning the key to start, hit it with a hammer. If it starts, replace the starter.

The starter is good? Try tap with the hammer.

Follow the thick red cable from the battery positive post to where it terminates, it attaches to the starter.

First thing to do is look at the dash lights when you put the switch in START position. If they blink or dim, you may have a faulty battery or poor connectivity.
Next try jumping the starter. You'll find a starter jumper at almost any auto parts. If you get no result then the problem is with the starter, If the starter turns then the problem is in the starting circuit from the switch to the starter relay.

The starter is where the engine joins the gearbox, usually on the engine side. Check that he wiring it connected at the starter and the ingnition switch. Make sure the battery terminals are good and clean and tight. Otherwise the starter solinoid may be faulty, or the starter itself.

your starter needs replacing not to hard of a job to do yourself

check to see if starter relay clicks while turning key to start position,if it does click check to see if voltage is reaching starter solenoid..if voltage at post on starter solenoid,but not cranking replace bad starter..(starter relay is located in fuse panel under hood..place finger on it while someone turns key to crank position ..should feel light click)

Starter, altinator

before replacing your ignition control module, it is a good idea to test if it is your starter/solenoid. I dont know if the solenoid is built into the starter on this car (many or most newer ones are) but either of a bad starter or solenoid could also cause a no start condition and is probably a more likely and simpler problem scenario. When you say "nothing happens to the starting section" do you mean you've already tested that no power goes to your starter or simply that when you turn the key to the start position nothing happens? If you have a voltage tester there should be a smaller red wire leading to the starter/solenoid in addition to the large one going straight from the battery box. If this is 'hot' or has voltage when the key is turned to start (12-14 volts is good) then the ignition module is not the problem. Remember that on your VW you can only hit the start point once for each key cycle.. ie before your 'start' point works, the key has to begin in the complete off position. you can't 'retap' start from the on or acc position for additional tests.

Starter relay clicks but starter is not turns over. Check the starter connections and starter itself.
Good Luck
