Hi there!

I have a yellow CEL, and the codes read as follows:
P0134 : O2 sensor heater circ. bank 1 sensor 1 malfunction
P0135 : O2 sensor circ. bank 1 sensor 1 no activity detected

BEFORE I bring my beetle to a mechanic, I would like to be informed about whats actually wrong with my car. Seems like it just needs the oxygen sensor replaced? I know simple things are often more complicated with a VW, so does any one have any advice?

Is the O2 sensor something that I can buy online for cheaper and bring to a garage to have them install it?

Thanks so much, this forum has saved me soooo many times, thanks!!:D
