AMF Engine Loaders: Part Numbers & Info

Unfortunately, my turbocharger is broken.
VW wants 504 euros plus VAT for a replacement charger.
The part was completely flooded with oil.
Could it potentially be repaired (with a flat rate of 300 euros for the TÜV inspection, including new bearings, seals, and balancing)?
The VW part doesn't seem too expensive... but I'll never see the old one again, and I won't know what the problem was.
What would you do?

Regards,

Olaf.

Thank you...

Based on the title, I understand that you are looking for the part number?

Hi!

So, rebuilt turbos with new bearings, seals, and balanced shafts are practically brand new... what else could possibly be broken?

If the shaft and blades of your turbocharger are still intact: Take it for repair and save €200!

The replacement part from VW is also just a reconditioned one, so you will likely have to return your old one as well .

Factory-new Garrett turbochargers are certainly more expensive than €500.

Actually, I'm looking for the Garrett part number, because the turbocharger rebuilder mentioned that he's had bad experiences with the part numbers provided by the car manufacturer, specifically that it sometimes turns out to be a different turbocharger in the end. I'd also like to know the price they're asking for a replacement turbocharger, as that would include a precise diagnosis of the problem with the previous turbocharger.

Apparently, it's just disappearing at VW (the thing is unfortunately located at VW, because these kinds of things always seem to happen when you don't have time).
How can I determine if only the bearings and seals are broken? How am I supposed to check if the shaft and blades are intact?
The savings aren't exactly 200 euros, because there's approximately 40 euros of shipping costs to consider (round trip) plus the cost of parts, in case the loader isn't in perfect condition anymore.
"My main concern is to determine whether the turbocharger failed simply due to a lack of oil, or whether there are significant signs of contamination on the exhaust side that might indicate a need to modify the engine's control unit (chip)."
While the loader has lasted 100,000 km, it probably could have lasted a bit longer.

Sure, here's the translation:

"Just for information:"
I checked out my loader today. It's actually in really good condition; there are no significant deposits, the turbine blades are fine, and there's no noticeable play in the bearings.
It's just that the seal on the fresh air side has worn out.
"Nothing came out on the exhaust side; they even disassembled the catalytic converter and checked it."
The VW master said that turbochargers that were damaged by excessive boost pressure look different. A connection to the chip seems quite unlikely...

Olaf.

I also took the opportunity to examine the deactivated AGR valve. It was completely clogged, but that was probably due to the oil that the turbocharger had forced through the entire system.

The new loader costs €983.68.
If you trade in your old device, the price will be €584.64.

Of course, prices include VAT.

If you're not in a huge hurry, check eBay. They often have turbos for sale, and you might find one for your 3-cylinder engine. I've bought two turbos there myself.

Otherwise, I would suggest buying it from VW as a replacement part. That way, you can be 'sure' that it's a good quality part and you'll have a warranty.

If it appears that only the casting is damaged, I would definitely have it repaired or buy a replacement charger myself, unless you have significantly more money than time....

It depends... definitely at over 2 bar at 4-5000 RPM... then the shaft breaks on the outlet side, and the turbine wheel grinds its way towards the exhaust - I've unfortunately seen something like that before.

But what about constant, slight overload?

A turbocharger rarely fails 'on its own' with mileage below 150,000 to 200,000 kilometers.
It always depends on how it's treated (temperature, oil, etc.).

If you've driven 80,000 to 100,000 kilometers with a chip (and thus increased boost pressure), a defect in the turbocharger is not unlikely.
In one case, the bearings } wear out sooner, while in the other, the } seal } fails earlier. Both are significantly more stressed due to the increased rotational speed of the turbocharger shaft, which is caused by the increase in boost pressure.

You're probably right about the need for repair. However, according to STK (presumably a repair service), the repair itself would cost at least 300 euros, plus around 40 euros for shipping both ways.
However, I still run the risk that they might think something is no longer working properly.
In the end, I won 240 euros.
Unfortunately, the car will have to sit there for quite some time until the part is available... and then I'll have to deal with VW, who, of course, want to make their sales.
