- I'm still not positive whether priming is necessary or not. What do you think?

Hello from Devon in the UK - if you were a service centre I would bring my car without hesitation. Excellent detail in the presentation. We in the UK call the ‘prime’ function a ‘pump-learn’. The control box relearns the voltages and current that control the pump speed/pressure. Without the learn it will remain 2x2 as countless folk have discovered. Happy Christmas to you and yours
just out of curiosity does the car need to be running and in p before activate the pump prime
thanks
Some videos seem much easier to find than others, but this one has been the one I’ve found most helpful to me so thanks for taking the time, the editing and the commentary. You got the balance just right!
Having done this myself. A few notes for anyone reading comments deep enough to get here:
I had no slack in the cable for the pump and I couldnt remove the plug for the haldex co trip unit so I had to remove it using t30 torx bits. It’s not easy to reach these, so check you can either remove plug before going ahead or make sure you have the tools to reach these t30/10mm bolts that hood it on. Once out you can use a screwdriver to pop the plug off by pushing from within the small hole on the plug.
When refitting the pump, you need to return the wiring. It’s easier to return the wiring and ready up the clips before pushing the pump back in.
Using OBDEleven, the pump priming option is found in All Wheel Drive and then Basic Settings. For it to work the engine needs to be running. I ran the pump twice and got a decent bit extra in, nearly 100ml.
The main problem with this job is reaching bolts and plugs. I had loads of sludge on the filter at 29k , but the oil wasn’t that bad looking and I hadn’t notice any ill effects. Glad to have done it tho! Will be interesting to discover if the sludge returns when I do it again.
thank you for the awesome 7.5R vids! i put 40k on mine and its hard to find DIY service vids, keep up the good work man
This is the best video I've seen on Haldex service!
Another great video. I was looking for another hand pump and I may try yours. I’ve done basically the same process except adding more fluid after priming. I’ll look into doing that next time.
Fantastic video
Oil looked really clean, how many miles were on the car at the time?
would it be a good idea to use hear to warm that bolt first?
Thanks so much. Keeping the pump attached makes this much more do-able on jack stands. I'm looking at the service manuals and don't see anything about priming. I searched the Rear Final Drive manual for "prime" and nothing came up.
Great step by step video and also love you give your take on the experience without forcing a conclusion.
A bit hard to follow the OBDeleven steps for temp check and priming the pump. Where exactly is this done in OBDeleven?
Go to awd, live data, and just search for temp, and you’ll see a few pop up. I am still not sure which is the best one, but they were all pretty close anyway.
@@EVERYTHINGcpo Excellent, thank you. Will check that. And priming the pump? Where/how did you do that?
@@stephankaeser8939 I think it was all wheel drive > adaptations > pump motor
@@EVERYTHINGcpoAwesome, thank you. I should find it.
I want to do mine. I was told it was done in 50k intervals I’m about to hit 50k miles on my R, kind of afraid to mess anything up, and tips for tools, or anything I need?
Something you didn’t mention (not sure if you know). The two o-rings are not the same size. The rear is slightly bigger.
When in doubt prime it out. ;)
Super Good Stuff!
There is much disbelief about the GTI's with PP as well. We have the same pump w/o the Control Module that the R has. I don't know of anyone that has at least removed the pump and cleaned their screen - especially when you have higher torque tunes. Will be doing this to my GTI's pump, because we are "enthusiasts" right! Don't want that sucker to go out that's for sure. Thumbs up!
Would you also need to service the front differential? If so how often or are these done together?
If your front wheels spin and you decide to replace the oil and clean the pump you MUST to prime the pump.
On a mk7 golf gti which has the e-diff would the haldex and e-diff service be seperate? So taking of haldex pump and clean the gauze/mesh filter be enough, is there a stock mechanical front diff separate from e-diff which also needs a lubrication service? TIA
I believe haldex is only on AWD systems, so not applicable to GTI
Great video! So far I've changed the fluid on my MK7 R three times since I've owned it (once every 30K km). First two times the filter was about the same as yours, most recently it was absolutely covered in gunk! I wasn't having any AWD issues before but I can't imagine the flow was that good. It's an easy service that I'll keep doing and will be interested to see if it's going to be better or worse.
Awesome. Do you prime yours or just fill it and go?
@@EVERYTHINGcpo I use my OBD11, reset adaptation, prime, top off, and prime.
You might be able to use the OBD11 to monitor the pump current. In another video, they found that the pump current was much reduced after cleaning a very gunked up screen. So, you might be able to check it periodically to see whether the required current is increasing, which might imply a contaminated screen.
Tried reusing the mounting bolts for the pump and broke as I was torquing one. So get replacement hardware folks.
Your screen is actually pretty clean. I’ve seen a lot worse.
its obd 2, not eleven. there was obd 1 and now there is obd 2
Ummm OBDEleven is in fact the name of the product. Sorry to disappoint you. amzn.to/3y9NQyl
@@EVERYTHINGcpo probably a product name, but the interface is called obd2 / obdII (with roman #s). Your video was very useful, jut the obd name correction.
@@eleazarcassis2870 I was telling you the name of the product and app I was using, not the interface - in the same way I didn't use the term can bus to describe how communication happens between the app and the car. I assume you don't have an OBDEleven yet. I highly recommended is. It opens up so many options on the car. :-)
@@eleazarcassis2870 And to just make sure we are 100% on the same page… not once in this video did I ever reference the OBD2 port. Not a single time. I don't know what you think you heard, but now that you know that OBDEleven is the name of a product, I think you’ll hear it correctly. I also mentioned VCDS, which is another product (that I don't have) that could accomplish this task. But again, never mentioned the port. 😎
He quite clearly states what OBDEleven is - you watched 14 seconds and decided to be a know it all. You might want to check this guy’s channel - he knows a ton about his Golf R and available products to use to service it.
