Hi guys, Took my A4 B6 into dealer today to get looked at ref 12 year corrosion warranty and when he drove it round the back he said he could feel juddering and said it'll be my power steering pump!? I know theres a judder when I turn but didn't know what it was exactly. Does anyone know if this is a big/expensive job? I'm starting to worry a tad as he made out it was urgent and was pricey to get fixed. Cheers!
