Hey guys,

just a quick question ref Lambda sensor... I have a fault, vagcom 17526 which i believe is oxygen sensor b1 s2 which i have found out is the post cat sensor.

Went on eurocarparts after getting code from Welly's thread (LEGEND) for 20% discount 'SERSAVE'. Only issue i have come across is wiring, the seem to have for sale a pre terminated and non terminated version with a 20 difference.

Question really is ... How difficult is it to re attach non terminated cable?
