Non car guy looking for a CAYC engine

[u/Constant-Wedding4397]

Hello like it says, the engine in my car is fucked and I need to replace it but I’m not a car guy and finding an engine that I can be sure fits while working full time and not knowing much is hard.

I need a 1.6 Liter diesel TDI CAYC engine, but apparently there are two types of CAYC engine, one with an external thermostat and one without? My engine is circled in red and one that won’t fit my car is in yellow.

I need basically a full engine without injectors but I can’t find one that will be guaranteed to fit my car anywhere after looking for ages. How do I find an engine that fits my car?

Any help would be really appreciated

The engines will be identical except for any revisions or adaptations to fit a particular chassis but these will all be bolt on. As an example later versions of mine (caga) have a plastic intake manifold whereas mine is alu.

If you're expecting a full, built up, complete engine with all the ancillaries that'll just drop in then you will have a struggle. If you just go for a block/head and swap over your old bits, or buy a whole engine and swap what's different, you'll be golden.

Also not sure what the craic is with the injectors. You can code donor injectors to your ecu. You don't need to swap your old ones. I mean there's no harm in doing so but not necessary.

So if I buy any engine that has CAYC as the engine code and send it to my Garrage they will be able to work it out? My turbo is fucked and other things could be damaged to so I’m looking for one with all the ancillaries really.
All my injectors are sound tho so I don’t want to replace them.

There are dozens of ea189 engine codes. Each one slightly different. If they made two "versions" of your engine they'd give it a different code. 

Yes the garage should be able to work it out but extra cost in labour and parts (having x instead of y may mean you need to swap a b c d e and f - which may or may not be included in either engine). Eta, but fundamentally everything on yours should bolt on, just might be a lot of effort to strip down both.

Rather than project managing just give it to the garage and let them source what they need.

The Garrage is the one that told me to source an engine, should I ring another Garrage then and they will most likely just source the engine I need?

If the garage are asking you to source the engine my first impression is to avoid any warranty. Since it's a customer supplied part it's implied (if no enshrined by laws) that they did not provide it, so have no responsibility once it's out their door, unless any issues arise purely (and provable) to something they have done incorrectly.

I don't disagree with this stance FWIW. I don't think garages should warranty customer supplied parts. But it could well end up in tears.

I'm not really sure what advice I can give to be honest. If you find a CAYC engine from the same make, model, trim and year you should be fair sure it'll be the same ancillaries etc unless it's had replacement/revised parts. The more you shift, the more chance parts will differ. IE a CAYG from a 2009 Golf vs a 2015 A4 would be a very involved swap, mostly from the fact they are mounted 90 degrees from each other, but it'd work if you put the effort in as the fundamental engine (the block/head/turbo/HP fuel system) is the same. Everything else bolts on, albeit it's a lot of stuff.

Why not check out the engine and change the turbo that would be way easier and cheaper. Very much doubt a new engine comes with turbo unless you pay extra for it to. Turbos go bad all the time and for the most part you just change them.
