Car makes loud noise when i turn it on

The only way to diagnose is electronically by asking an auto electrician to scan it with a pro grade scan tool computer. They can also record what is happening on a drive! It sounds a mess for sure, mechanical and electrical and the computer can diagnose both.

I GUESS that the speakers are driven by an after market amplifier. An amplifier needs to be connected to a power source that is only on when the radio is on, through a relay.

So I GUESS that:

1. The wiring is incorrect. Or
2. If is has a relay, the relay is stuck.

Gave the CV axle joints checked.

Sounds like a wheel bearing .

Have the wheel bearings been checked?

I HAVE THE EXACT SAME PROBLEM! DID YOU FIX IT?

Check front tyres & wheel bearings espesially the R/H/F. Feel tyre for high / low spots on inside & jack up & spin wheel if you get noise while jacked up it is not the tyres but wheel bearing or brake pads but more than likly a crook bearing by the sound of it. It needs to be tended to ASAP

Ok, so are you saying NO LIGHTS come on to tell you what issue is on the dash? The beeping you hear is a low oil pressure warning beep. Its telling you that you are either low on oil or that the oil pump is not delivering oil properly to the motor (car is sensing low oil pressure but on these cars there is no oil pressure gauge on dash to look at). Check your oil level and make sure you are not low. Best time is in morning on flat surface start car and let run 5 minutes. Stop car, let sit 5 minutes and then pull dipstick and check level. Also make sure you are using the correct oil and viscosity for this motor. VW's require VW certified oil and a certain viscosity. You can go to www.mobil1.com to find the correct oil available in the states for your vehicle. Too thin or too thick a viscosity could cause similar issue. Otherwise please clarify the light comment as I have never heard of the lights coming on automatically after a beeping noise and I will research.

the right outer tierodending needs replaced.

If you are using the smart key and you do not have it in the ignition, it will send a signal thru the car speakers to let you know that the keys are not in the ignition(beep,beep,beep,beep), and that they are to far from the sensor. Next time you are driving and the keys are in your pocket, pull them out and wave them around the speedometer. It will notice keys in car and the beeping will go away.
