I have been using my bluetooth in my vw golf with my iphone4 for a while. all of the sudden it will not connect and the phone says to make sure the vw bluetooth is turned on...but i pressed the bluetooth button in the car. so my phone bluetooth is on, and the car bluetooth seems to be on...but they won't connect to each other. how do i fix this?

Alot of European cars are made with the older basic 1.0 version of Bluetooth, where as phone's these days are being made with the later version 2,0 i think. To get around this if taken back to manufacturer some will have a patch to run over the bluetooth in order to upgrade or just simply buy a new bluetooth carkit and install.

Without knowing the model of radio fitted to your car I would make the following assumptions

The CD Player is Locked Out:

Either

Because the battery has been disconnected and the clearing sequence in your handbook was not followed correctly you may have to wait several hours between attempts to unlock it and you will need the original code at hand as a fail safe

Or

The CD player is from another VW car and the on-board code in the memory does not match that one.

Resume:

You need to look out the little book that came with the car and read up on clearing the code for that particular model.

Last resort is a VW Dealer who should provide assistance free of charge , according to the handbook

check spark plugs and distributor. look for bad wear and missing parts. It must be a faulty spark plug which is not igniting fuel in one cylinder. If you decide to replace the plugs its best to change all of them.
