I was just doing another check on ETKA and noticed something else.
Cars built up to 30/4/2010
Original tensioner 06H 109 467 N, New tensioner revision after 01/05/12 06K 109 467 K
Cars built after 30/4/2010
Original tensioner 06H 109 467 T, New tensioner revision after 01/04/12 06H 109 467 AB and then revised again on 01/05/12 to the same part number 06K 109 467 K as above
Also listed along side this with the same tensioner revisions is the CDAA engine, 1.8, 160bhp petrol used in the Skoda Yeti and the Seat Leon MK2 (1P)
