Intake manifold compatibility 2.0tdi

[T07]

Have tracked down a coolant leak to the charge cooler (camera through IAT sensor and wet inside). 
 

I’m trying to track down a compatible part, new genuine is around £800 so looking for second hand or eBay. 
 

Anyone know how to confirm compatible part numbers? Latest revision according to the dealer is 04L 129 766 Q

 

There are lots of other revisions out there so not sure what fits. A few AJ revisions on eBay, but can’t track down whether they will fit. 
 

thanks

Searching for that suffix Q part on Skoda Parts.com gives the following part numbers listed along the top the page Škoda part number: 

04L 129 766 BA

04L 129 766 AM

04L 129 766 B

04L 129 766 H

04L 129 766 N

04L 129 766 Q

04L 129 766 S

 

Intake Manifold Škoda 04L129766BA (skoda-parts.com)

 

I think that indicates that all are interchangeable.

 

What's the part number of the one currently on the car?

It’s a 04L 129 766 Q on it

[Breezy_Pete]

@varooom may be kind enough to confirm/deny whether those other numbers from the skodaparts page are all supersedences of one another.

04L 129 766 Q --> 04L 129 766 AM --> 04L 129 766 BA

 

This is how your part changes to the latest version

[T07]

Thank you!

[Breezy_Pete]

Yes, thank you @varooom.

I was able to confirm using OEMwolf.com that B>N, N>Q, H>Q,  and strangely unalphabetically S>Q (where '>' is intended to mean was replaced by).

But that site isn't up to date enough to cope beyond Q.

 

 

[T07]

Any way to check cross compatibility across Vw group? Can seem to find these from golf’s or Leon’s but struggling for an Octavia one

[Breezy_Pete]

If the part number is the same, it's the same irrespective of brand.

[T07]

Ahh not ideal then. Can find a few that don’t match the codes on skodaparts. Different modification letter so not worth the chance. 
Thanks 

[Breezy_Pete]

 

To my eyes the last letter of the part number engraving might be an N rather than an M though?

Was trying to source newish but looking like that might have to do. 
 

Anyone aware of a weakness in the earlier versions that was rectified? Or was it just one of those things to go. Done about 120k miles

[Breezy_Pete]

You'd definitely not want that one if it is really an -AN, that could be quite different.

Stick to one of these 3x values to be absolutely sure of a compatible fit

[varooom]

The link that @Breezy_Pete linked to earlier (removed extra crap) should be good enough to replace what you have.

Ideally find a BA version, but probably hasn't hit the eBay market yet for being too new

 

Thankfully AN is not a legit part, so contact the above seller to confirm that it is AM not AN

Best of luck!

[Breezy_Pete]

Could also be AH. I just can't see dots where dots should be to make that last letter read as an M?

True, worth getting them to wipe the grime off it.

[T07]

Yep it was a typo, was actually AH. 

 

Any idea where the aj part comes from? Can’t find much info on it but the below eBay description seems to say it’s compatible. Waiting on a response from the seller.

The weld on that looks very suspect, looks like its had a new core welded in the middle of it.

Any use?

[T07]

Unfortunately I don’t think so. The version ending L seems to be slightly different around where the Egr valve is than the version ending Q. 
 

Think I’ll have to take a punt on one

[Phil2013]

OK so Dark side developments are selling new latest version coolers says for the MQB platform but doesn't mention the Octavia in the list and the part number is slightly different 

 

https://www.darksidedevelopments.co.uk/products/genuine-mqb-charge-air-cooler-04l-129-711-ab.html

 

Supersedes part numbers

 

04L129711AB - 04L129711 AB - 04L 129 711 AB
04L129711D - 04L129711 D - 04L 129 711 D

[T07]

dark side were very helpful when I was in touch, but they couldn’t be certain that the one they stocked would fit. Seems to be a couple of different versions around which are all slightly different. 
 

Have ordered a second hand part so will try and pressure test it when it arrives and fingers crossed it’ll last another few miles!

[Phil2013]

I sent them a query on the part number 

 

Quick responses as ever and the correct part for (in my own case) a CKFC 2.0 cr tdi  is 04L 129 711 AB 

 

only from VW @ £795 +vat.....

So by the looks of it the AB version has an opening on the right hand side that on the Q version isn’t the whole through the casting. Don’t know what the difference is on the engine itself
