ALH TDI VE Pumpe tropft - Frage zu Dichtungen | Posts 16+

Thank you for your help so far.


I was able to order the seals yesterday and pick them up today .

Ollenik GmbH - Bearings and Industrial Supplies.
54a Blumenstrasse, 47057 Duisburg.


I received both rings made of Viton; they are black, not green or blue anymore.
They are still round and not oval or rectangular, but that's not a problem. Size and length are correct, and that's what matters.
I kept the large lid because I don't suspect any leaks in that area. Interestingly, you can buy them individually from Bosch.


This evening/afternoon, the part will be installed, and then we will pray that no more diesel leaks.



Photo if anyone needs the part numbers - these rings are not sold by Bosch.

PS: The part number for my engine mount - which I was constantly asked about and couldn't find - is: 2 467 135 216. Maybe this will be of interest to others (I have an ALH engine).

After initially being sealed, it is now leaking again.

I also tightened the screws, but it still leaks after a longer ride . It seems everything is leaking inside as well, so it's probably a case for a professional overhaul, right?

Have you had any experience with that? I just got a contact from a pump technician who said he could seal the pump with new gaskets.
Unfortunately, he didn't want to say anything about the price .

What should one expect regarding the treatment of the pump if it is A) installed or B) removed?

Hello Alex,

It's a shame that all the effort was ultimately for nothing.

Perhaps you've already read my detailed report. I'm also affected. I've been using both biodiesel and regular diesel for years, when there was little awareness of the disadvantages. Now, the ESP (likely referring to an exhaust system component) is leaking, and I now have to continue using only biodiesel to prevent further leaks. The question is only for how long?

Since I know I'll eventually need to have the sealant on my ESP replaced, I've already done some research.
Bosch wants approximately 650 euros for the overhaul, resealing, testing, installation, and diagnosis.

A free workshop isn't much cheaper, and they might not even be willing to do it. That's why I happened to find a private individual who has been doing this for years. Starting with agricultural machinery and progressing to modern TDI engines, he has repaired, rebuilt, and sealed ESPs (Electronic Stability Programs).
When installed, he wouldn't let me access my ESP system, as he's had bad experiences with it before. However, the cost for removal, resealing, reinstallation, and adjustment should be around 200-250 euros. That is, 200 without receipt/warranty, and 250 with receipt/warranty, since it's essentially a workshop.

Since my ESP system is currently working properly, he didn't want to repair it immediately, but rather wait until it malfunctions. That could take days, or even years. When that happens, I will leave my car with him for the weekend. I will also insist on being present during the repair. I also want to learn something from this, as I haven't repaired an ESP before.

If the car is still drivable, it's definitely worth comparing prices, because you can go to Bosch anytime.

Good luck!

I will let you know when the car has been to the workshop (hopefully the mechanic will be back from vacation soon).


'650 euros, ouch. It really hurts to invest that much money into an old engine again. I was almost expecting it. The Bosch service centers around here won't do it, they're either afraid to tackle it or don't want to. They just want to sell a new pump, especially VW.' I guess I'll have the belt changed at the same time; it's due for replacement anyway, and then it will probably be a complete overhaul.

Okay, so if more people have their pumps sealed and would like to share their experiences, please do.

Good day, Rainer, I wanted to add something, but I can no longer reply to the original post (only moderators can do that). I had problems with my VP37/Mengel injection pump back then, and during the timing belt replacement, I had another company handle the sealing and membrane replacement. So far, so good. Now, I wanted to add the costs to my previous post. Sure, I can do that. Here's the translation of the German text: "Or can you add something to the end, just to finish the story." Anyway, it's not leaking anymore, and the repair wasn't that extremely expensive, considering the original price. I was just about to buy a replacement pump. This is the thread: /viewtopic.php?t=6525&highlight=deralex I paid for the following: VOLKSWAGEN GOLF IV 1.9 TDI ENGINE. ALH 1896CC 10-97 to 09-02.

After the car was in the service for an insignificant amount of time, and whatever "membrane replacement" might be...
