Hi All

Newbie to VW's here

Recently I bought a 2001 Passat TDI Automatic with 66000 miles on the clock.
After about a week the brake warning light on the dashboard kept coming on, to which i assumed the pads had worn ?? upon taking the wheel of the pads looked OK but seeing as ihad bought some new pads i decided to fit them anyway. and Hey Presto no more warning light but now the brakes are very spongy (displaying all the signs of air in the system). although I cannot fathom out how this has happened as there was no fluid used,spilt,accesed or leaked.

Has anybody had similar problems/ is this common/ is there a cure other than bleeding the brakes (read somewhere about possible code error but not sure if that would affect the brakes)

Please help

Many thanks
