Pesky 17544 error and possible part number confusion

Hi,

been lurking here for a few years and not had much cause to complain about my 51 Octavia vRS, til now.

The story:

1) engine management light came on before trip to Lake District, so went to a local bloke, breather hose replaced; ok for 400 miles, then light came back on, back to same guy who said it was a fuel pressure problem, have to go to dealer.

2) Tried a local Seat place but they were cagey about fault codes 'may not be the same' or some crap so took it to nearest Skoda (reluctantly). Said they found an air leak (but no parts on the bill: 'only' one hour labour. Drive for 100 miles, light back on.

rather than repeating steps 1 and 2 (and using up 190 quid each time round the loop), I bought a VAG-COM lead from a guy on eBay and eventually got round to looking at it this lunchtime. 17544 error. Much Google-izing later and a poke under the engine covers, I come to the conclusion that its the (infamous?) vacuum pipe under the manifold to the right of the dipstick. I haven't removed the bracket in front of the manifold yet but the pipe feels like mush and there is what looks some tape round the hose just beyond the first bend (no wonder no charge for parts from the stealer ... or maybe they missed off that well known VAG part "15cm electricians tape").

If you look at Pic & part number help pls you find a post on uk-mkivs with some good pictures and instructions on replacement of this hose.

Anyway, the real reason for this post is that it looks like from that link (search for "Item 26 references a different page on ETKA") that the correct part number 06A 103 221 BK (was AF) may easily be confused in the ETKA catalogue with the Y shaped oil breather hose (Item 13A, same number with AH suffix). The catalog on vagcat.com refers you to another page which is one named "Ventilation for Cylinder Head Cover"). Item 26. appears in the ventilation diagram as item 10 on that page btw.

I've actually replaced that other hose (06A 103 221 AH) as well (oil fumes in the cabin), pictures Split bloody crankcase breather hose and Hose underneath engine cover! - SEAT Cupra.net - SEAT Forum

So when you are ordering these hoses, make sure you get the right suffix (AH for the Y shaped oil breather hose, BK for the kinked vacuum hose). The AH is about 27 quid, the BK 12 quid. Its been mentioned here before but it perhaps wasn't obvious that the part numbers were so similar.

Pictures of the botched tape up fix to follow and hopefully a happy end to this tale.
