How can I tell if my VW starter is faulty?
1 The battery may be dead. 2 The battery terminal connections may be loose or corroded. 3 The grounding straps (including the tranny-to-body strap near the nose of the transaxle) may be corroded/loose/broken. 4 The starter solenoid may be faulty. 5 The starter motor may be faulty (see below). 6 The ignition switch may faulty.
Why does the jumper test not work on my VW?
If the jumper test causes the starter to engage and to crank the engine then the problem is in the wiring or the ignition switch, with the higher probability for the latter. If the jumper test didn’t help then you’ve narrowed the problem down to the solenoid. Fortunately, the fix is pretty simple.
Why does the solenoid stick on a VW starter?
The usual reason for a solenoid to stick is due to rust on the plunger. The proper fix is to remove the starter, dismantle the solenoid and DEAL WITH THE RUST. DON’T go pounding on the solenoid with a hammer! Yeah, this also works. And damages the solenoid in the process.
How do you replace starter switch on VW?
There are two safer ways to do this. One is to detach the starter-switch lead from the solenoid and replace it with a jumper having a female spade-lug connector on one end and an alligator clip on the other. To complete the circuit, TOUCH (do NOT clip) the alligator clip to the battery cable connector. Do NOT touch the copper stud nor the nut.

What should the battery reading be on a VW?
If you have a Volt-Ohm meter, place the leads across the battery terminals with the meter set to “volts.” A fully-charged battery should read about 12.5V; at any reading lower than about 10V the starter motor will not turn over or will do so very weakly — and the plugs will probably not fire.
