Hey all I know I don't own an octavia, but seeing as we're all part of the vag group I was wondering if I may have some assistance as i need some advice after doing some of my own research on the switch between the BMN plastic manifold to the alloy bkd manifold.

So I have a 2007 (57) seat Leon FR 2.0 TDI PD170 and unfortunately I have a nasty leak coming from the inlet manifold (around the actuator) there is a loud hissing sound that comes when you rev, also there is oil of some sort which has sprayed out around the area and underside bonnet. After doing some searching I found you can pretty much bolt on a 2.0 TDI BKD alloy manifold onto the BMN engine. From what I understand the part number for the bkd manifold is 03G129713 however when looking for this part I came across 2 types of manifolds; one with 03G129713, and one with 03G129713AF... Now I'm confused on which one will fit onto my car as from what I've seen the 03G129713 seems to be alloy and the 03G129713AF looks plastic... So a bit more research and a come across people saying after 06 your require AF while other say the alloy manifold is fine. Also when installing the bkd manifold will I require a gasket and if so which one to accommodate the bkd setup. Another confusing question I need answering is the bolts required for the fitment... Some are saying I can use the existing BMN bolts while others say I require the bkd manifold bolts? If I require bkd bolts where can I get these from? Lastly as the bkd manifold has no flaps and the original BMN manifold does what am I to do with the vacum pipe that initially went into the swirl flaps?

Please advise before I run into bigger problems :( :( :(

Thanks in advance guys

I posted on Facebook recently about this, you can use the bmn bolts but they need spacing with washers or else the manifold will be loose. Bkd ones are the proper ones for the job

Cheers for the reply mate... In terms of the vacuum pipe, how can I bypass the function as there are no swirl flaps for the bkd also can I use the bkd 03G129713? Or is the 03G129713AF required? Also have you got a link to your Facebook post so I can read up on the switch

Regards

How much did the bolts need spacing up and what size washers did you need? Or is there anywhere to buy the bkd bolts?
