The AJM is a 2002 model, and based on the "C" marking, my production date (ASZ) is 07/2002. It definitely has an "R" marking.
Regarding the AJM part, something seems strange. It looks like the original letter was removed and a "C" was later added. The "new" used replacement head I have is also marked with a "C". If it's helpful, both of these (the AJMs) have PDE numbers that end in "F".

Now the question is what's different about D, and for goodness sake, what exactly is R?

@Roger, do you have the Golf that was produced before or after mine? What letter does it have? I'm kind of curious now. It's located on the far left side of the cylinder head; just lift the plastic and move the sound insulation slightly to the side.

Okay, one more thing: I knew quite early on that my vehicle doesn't have a GSH (presumably a specific type of system). Also, my KGE (likely an engine component) is not heated. According to my documentation, all PD models should have this feature. I'm now considering retrofitting the heating element from the "broken" AJM engine... although why would I even do that?

I wasn't there when the belt broke. I don't even know the owner. So, I would have to ask, but I think it doesn't really matter much because the valve of the first cylinder absorbed most of the energy. From there, the damage will always be "less severe."

The PDEs (Partial Differential Equations) probably don't have any deeper significance here... Also, the "akte" system only shows me "...D - ZK" for MJ 02.
However, it has been replaced by the 03G 103 351 C - I overlooked that earlier.

Hi,

But I will still have this "pleasure" today...

Best regards,

My condolences to you, may you have more luck than the head I'm currently holding .

Hello,

"The head survived!! The hydraulic lifters were completely worn out, and the valve tappets have no dents or damage - but the lifters themselves are a complete disaster. Valves 2E +2A are defective; one of them looks like a question mark. Because of this, I installed new valve guides. Pistons 1 and 2 have clear "impressions" on the exhaust side, so I'll remove them and check them. I might also replace the connecting rods (I still have 4 old ones somewhere...). "
More photos will be provided later.

Does anyone happen to have a turbocharger lying around for a RA/SB engine? It's not in the best condition anymore!

Regards

. Also, my KGE (cooling equipment) is not heated. According to my university documents, all PDs (presumably referring to some type of device or system) should have heating. I'm now considering retrofitting the heating from the "broken" AJM , although why would I do that!

I'll check it out tomorrow (hopefully I'll remember }).
Why don't you have a glow plug heater? Is it a glow plug ignition system?
Mine definitely does...

"@ Roger --> Mine is from the Netherlands, and Jan6K also got his from there. It doesn't have glow plug preheating, for some reason."

I have a red car.

Okay, so the cylinder heads are the same, and "R" is probably actually real! Thanks, Roger!
