my fiances 98 beetle had been sitting for about a week or so. prior to sitting it didnt have the cel. we went to start it up for a drive and i popped the hood, added washer fluid, closed the hood and then she started it. the cel came on. i got it checked out today at autozone and the code was 411 secondary air pump flow insufficient. i saw in another thread that the vacuum lines should be replaced. is there a diagram that shows which lines and how much of what size should be replaced. what other things should i look for? also when you reset the computer how long should you leave the battery disconnected for?
