130 PS plus the current 30 PS

Hello!

My crappy VW still has 30 horsepower. When going downhill and with a lot of acceleration, it can reach good speeds of 110 km/h. With this, I'm sure I'll be able to transport a few cars with roof racks.
What the hell !!!!! The car has 6700 km on the odometer and is only 4 months old!!!
Since my VW is in such good condition and has also been consuming 1 liter of coolant for the past two weeks, I already have an appointment at the workshop on Monday.

What could that be? He doesn't rust, doesn't consume much, and only produces around 30 horsepower and 50 Nm of torque.
LMM?
The damage also didn't appear suddenly this morning.

Hi

I am assuming that the error log has not yet been accessed.

If the VP-TDI no longer produces any boost, the temperament remains roughly that of an SDI, i.e., around 60 PS.
With the LMM disconnected (simulating a complete failure), the result is similar.

A power loss of approximately 30 horsepower is unfamiliar to me when considering things like completely clogged air and fuel filters.
I have no experience with PD's (except for a test drive with a 75 PS Polo).

If the water loss is due to a faulty cylinder head gasket, the engine may have suffered a "waterlock" upon starting --> bent connecting rods, etc. But even if 1 cylinder is defective, shouldn't more than 30 HP still remain??

Good luck and post the result, fortunately you probably still have warranty...

[Translating...]Hallo Ulf !

Danke für die ANtwort !
Also das Temprament eines SDI hat mein Wagen bei weitem nicht !!!!!!!!!!!!!!!!!!!!!!!!
Wasserschlag glaube ich nicht, denn dann müsste der Ölstand ja auch höher sein, ist er aber nicht.
Ich werde mal den LMM abstöpseln und gucken wie er dann läuft. Gute Idee von dir.
Ihr hört von mir.

I'm going to disconnect the LMM and see how it runs then.

I am very skeptical... removing a faulty fuel injector reduces performance, but more performance (due to other defects) certainly won't come from that

I believe a water hammer without an elevated oil level is quite possible:
If there is a hole in the cylinder head, only water (and only!) from a water channel will enter the combustion chamber after the engine is turned off, without any discernible amounts entering the crankcase.
With a compression ratio of approximately 1:20, the combustion chamber of the 1.9 engine has a volume of approximately 25 cm³.
D.h. 30 ml water loss in Murphy's "direction of greatest possible damage" can therefore already be sufficient

However, after starting the engine, the water level in the equalization tank should rise relatively quickly, because combustion gases enter the cooling circuit and displace the water there.
Sometimes, it can also be visibly bubbling in the container.

[Translating...]Habe den LMM abgestöpselt.
Das Auto läuft genauso wie vorher also ist der LMM wohl total kaputt.

I have unplugged the LMM. The car is running just like before, so the LMM must be completely broken.

If, for example, a prankster has folded a sponge into the suction tube of a snorkel, it doesn't matter whether the LMM is functioning properly or not.
The same applies, for example, to a piece of newspaper that could have wrapped itself around the suction unit.

I don't really believe that, but I just wanted to qualify the IMO's premature conclusion that "LMM is broken."

[Translating...]@ Ulf: Ok, das ist möglich aber sehr unwahrscheinlich.

Hello!

Have you perhaps already considered the possibility that it could be caused by a [MARDER/RABBIT]?

I experienced this problem twice with my TDI PD engine (74kW). The car could reach a maximum speed of 120 km/h!

Hallo,

wenn das Steuergerät schon im Notlauf ist, macht es meistens keinen Unterschied mehr, ob ein zusätzliches System ausfällt.
Ich würde zuerst die Meßwertblöcke auslesen lassen. Bewerten kannst Du sie anhand der Tabellen in der Fehlerdatenbank. Dann siehst Du sehr schnell, ob es der LMM sein kann oder nicht.

Hello!

Have you also checked all the hoses carefully? I had a similar problem with a 90 PS TDI. It wasn't even able to reach my driveway. I checked the hose between the air filter and the turbo, which is secured with two clamps at the front and back. This hose had come loose on the back side and had shifted slightly, after which there was absolutely no power, it was only sucking air partially through the air filter and the MAF sensor, but most of the air was coming from the engine compartment. This meant that the MAF sensor had much too little airflow and the measurement data was completely wrong. However, air turbulence could also occur, since you were already driving without an LMM.

Best regards, Tom

[Translating...]Hallo Jungs !

Ich habe richtig vermutet, der LMM ists.

Desweiteren kam ein Marderschaden dazu (Kühlwasserverlust), der hat den Heizungskreislauf angeknabbert.

Die Werkstatt hatte aber keinen LMM da ! Seltsam, das ist doch das am häufigsten benötigte Ersatzteil bei VW............

Hi

My goodness, if a faulty LMM causes the supposedly powerful PDs to drop to around 30 PS... I'm starting to have some doubts about whether such a drastic "emergency mode" is really necessary (if no other malfunctions are detected),

[Translating...]@ ulf: Man ach so starker TDI ist wieder so granatenstark wie vorher. Vielleicht haben die ja auch was anderes getauscht und mir nur gesagt der LMM wars.
