Found on 2002 vw passat tdi vag-code= 01336 and also 00476. Any ideas? Origionaly the brake lights stopped working and 'abs,glowplug light,started to flash,now the brake lights work ok (same switch taken out,cleaned put back) Glow plug light is still flashing (abs one has gone off)no other faults apart from ones stated above. Been on the wikki site but had no luck......one code is on the site,the other is not. The one thats on there,i dont quite understand what its telling me.
