Volkswagen Golf 1.9 TDI 74 - 77 kW

Hello, experts.

I'm currently in the process of buying a New Beetle Cabriolet with a TDI engine. Depending on the year of manufacture, they have either the older 74kW engine or the newer 77kW engine. What is the difference between the engines, and is it worth paying a significant extra price for the newer one?

Thank you in advance, and best regards.
Jens.

I only know the 74kW rating in connection with an EDC15 engine control unit.
77kW with EDC16, but I don't know if that's the case for the Beetle.

You can find information online. In 2005, the engine was changed from a 74 kW motor to a 77 kW motor, both being PD engines. This likely also changed the emissions standard from Euro 3 to Euro 4. (Source: AMS). You can find the MKB codes, for example, on Wikipedia, and possibly information about problems with specific engines here.
Whether a vehicle with a PD engine and Euro 3/4 classification is a good choice is something you need to decide for yourself.

No!

Euro 4 was available from model year 2002 with the engine code AXR, and that was a 74 kW engine .

74 kW -> PQ24 (Golf 4) up to approximately 2003/04.
77 kW -> PQ35 (Golf 5) from 2003/04.

Unfortunately, the New Beetle turned out to be a PQ24 model. During its production run, it was updated to the PQ35 platform (around MJ05, when the Golf Estate was discontinued).


The differences between the engines are minimal. The most noticeable changes are likely in the EGR (Exhaust Gas Recirculation) system and the cooling system.


EDIT: The 74kW engine was available in both Euro3 (ATD) and Euro4 (AXR) versions. These engines are fundamentally different.

Thank you, you are great, as always, one is helped very well here!

Most of the Beetles offered for sale already meet Euro 4 emissions standards and have a green sticker. If there's hardly any difference between the two performance options, it makes my choice much easier.

Best regards, Jens.

Mmmmh... Euro 4 actually came into effect on January 1, 2005, didn't it?

However, starting in September 2001, you could purchase a Golf with a D4 (later EU4) engine.

My old Golf 4 was like that.

For that, I received a few Euros in tax relief (for 2 years) back then, and later, I was able to get a green sticker without any modifications.

Euro 4 vehicles for both gasoline and diesel engines were available long before their mandatory introduction. In Germany, a unique approach was taken in 2000, with the introduction of its own standard (D4). This was later (in 2005) designated as EU4.

The AVB engine was/is a Euro 3 engine. Apparently, the electrically controlled EGR system is an indicator of Euro 4 engines?
I had a green sticker for my car (with an AVB engine) after installing an aftermarket DPF. It was a very reliable engine!
I am unable to translate "haithamina" because it does not appear to be a word or phrase in the German language. It may be a misspelling, a proper noun, or a term from a specialized field. If you can provide more context or clarify the intended meaning, I would be happy to assist you with the translation.
