Haldex + Redline MT-LV GL4?

[kschachn]

I've always cleaned the filter when servicing it, but this is not the standard dealership procedure.
If you remove the pump to do so, you're supposed to replace the o-rings on it, which are $90+ if you pay normal dealer pricing. So at a shop it becomes a stupidly expensive service to do properly, I can understand why they get sludge-y.

Yes even with the online discount at my local dealer they are just under $64 which still seems expensive. Elring sells them for less but not a lot less.

I got an elring set for $13. 147.480.

Probably best just to track down some generic viton o-rings, the bolts themselves don't need to be replaced each time.

Hmm yeah I saw rings on eBay.

Or just FCP Euro it, I'm on I think my 5-6th Haldex kit between the Atlas, S3, and my Sportwagen. The Vaico kit even comes with a new screen/bolts for it. But yes, the o-rings/bolts thing is pretty crazy in terms of price.

Eh, not a fan of vaico stuff. They sell new genuine pumps, I'd just replace the whole thing once a year.

I suppose that's one way to do it! I've typically used the Febi/Bilstein kits and just last year tried the Vaico for our Atlas. No issues, stuff looks "normal".

I bought some 44x2 and 46x2 Viton o-rings from McMaster-Carr. I’ll see how they work.

Just seems to be a "regular" manual trans/gear oil would be different than a wet clutch fluid was really all. In the FB group I mod (Alltrack/Sportwagen), someone was concerned that their shop used Motul 75W90 gear oil in their Haldex...I figure they just goofed and did the r. diff but folks were losing their minds to stop driving it etc. b/c it will be damaged...based on this I'd say no, may not work correctly with an oil of that viscosity vs. what is supposed to be in it but shouldnt' damage it.

Sorry for the bump, but this sounds similar to what happened to my Volvo XC7O with Haldex.

Mechanic used Redline Differential 75w-90 instead of Haldex Fluid. I only drove the car a few miles, so I hope no damage has been done.
I plan to change the fluid out immediately with new filter. The OEM fluid was not cheap though (+$50/liter)
I'm thinking of using MT-LV GL4 for future some drain and fills..

I don't believe this will damage a thing - it's just not the right type of fluid is my guess so the friction characteristics aren't going to be where they need to be for the clutch pack. Just drain it out and fill with the factory stuff or whatever is equivalent/meets the specifications. Have you looked on FCP Euro? They have the Febi and Vaico fluids for my Gen 5 systems that are cheaper than the OEM.

He's got a filter so it's probably not gen5. The concern would be the GL-5 EP additives damaging clutches I guess? Gear oil will just be way thicker otherwise.

Also this was a mistake, o-rings were slightly too large. Due to some mechanical and shipping mishaps I have a brand new pump and a spare. Beats dealing with o-rings for sure.
