Hello

Does anyone know location of front oxygen sensor and its control unit? Spent few hours but couldn't figure out where is sensor or control unit. I got new sensor and need to replace old due to sensor fault. Mechanic wanted to charge me $200AUD for work and $1280 for part. so I got brand new part for $240 on ebay and will replace it as soon as i can locate it
there is a DIY on this topic and it refers to photos. but photos are not attached so its hard to work out where is it. Car is Golf Sportline FSI 2.0 Australian model so its left road side model if that makes any difference.

cheers
