bad ground or bad power source behind radio and radios sometimes has fuse to the back of radio

fuse box
power wire fuse box this will be located on the power wire to radio
and then you have the radio fuse

some radios have what they call an antitheft shutdown if the code was not properly put in after so many times the radio completly shuts off or for a length of time it will also shut down the radio

recommendation take vehicle to dealer so they can show and reapply code for you to you then you would never forget how to do it

one cylinder probably not firing get rubbercoated plyers and pull wwires until you find one that doesn't change motor sound

have a load test done on the battery as it may be flat or have dead cell. Check and clean the battery terminals and battery posts (shiny clean ) as the moisture around boats causes lead sulphate to build up on the terminals which prevents current flow ( black coating)

You don't. First check air filter, if clogged, replace. Next, is your car throwing a trouble code? Try cleaning MAF sensor with carb cleaner (that's between air cleaner and throtle body), next, replace bank one of the oxygen sensor. I would start there. The problem running rich is a little generic, and the above are easy fixes. If this doesn't fix it, come back and we will move on to the next possible problem.

make sure the distributor is turning or check to see if the timing belt is broke. If those are good than check the crankshaft sensor. I would bet that along with no spark you also have no injector pulse. I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

Yes. there are suppose to be lower covers to keep water from spraying up on the belts when it is raining.I would check to make sure all covers are present and also make sure tension on belt is good as well.If all covers are present I would check into replacing p/s belt and having it adjusted properly.Hope this helps

Its either a blown fuse or the turn signal switch is faulty.

Not supposed to jump VWs. Sounds like your immobilizer kicked in. You have to connect to a diagnostic tester and clear the errors before its gona start. Go see how to do it on http://volkswagen-polo-highline.blogspot.com

Ok what do you need information for??

ok... first question... the Tach(rpm guage) does change when you rev your engine in either P or neutral? Also.. is your check engine light on? any odd smells(burnt eggs) if your check engine light is on.. it's most likely a fualty sensor.. based on educated guess idle air control valve .. ot maybe posibly a faulty throttle position sensor.. if you have a foul smell.. similar to eggs or just nasty... could be a catalytic converter went bad... reply and lemme know if i help.. or raise new questions :D

you could need a new clutch or clutch fluid or they just need to be bled

you have a bad alternator, it was put together wrong... take it back...
