Failed 2.5 VW vacuum pump

Today we learn how to replace the vacuum pump on 2.5l VW engines. When the 2.5l vacuum pump fails it will cause an engine oil leak. This oil leak can be mistaken for a rear main seal leak. This DIY will apply to the Jetta, Rabbit, Beetle, Passat and Jetta SportWagen with automatic transmissions.

    Hi, I just finished the job but it is a fail. For now.
    As soon as I started the car, loads of oil just coated my floor, in addition to many warning lights on my panel.

    Is there anything that you recommend, I check? Here are 3 things that did not go as planned: The rubber seal (inside the pump) came loose, so I put that back inside. The small 10mm bolt next to the pump, I could not get it to fit the wireloom and bracket, so I did not attach it. I did not torque the t30 screws – I used my judgement with a ratchet.

    Will appreciate any advice. Thanks.

    Great videos on the 2.5L vacuum pump “how a failure” and “repair the easy way.” The easy way video is for a manual transmission engine, correct? You mention in the failure video that an automatic requires transmission moving or removal.

    I have an automatic Rabbit 2.5L. Perhaps this is why the estimate from my local dealer is $807. Seems high for a part that is about $270 [Deutsche auto parts] and maybe 1-1.5 hour repair time.

    Any thoughts?

    Thanks for the excellent explanations.

    I have a 2011 Jetta 2.5 that’s leaking oil from the vacuum pump but its leaking at brake booster . My question is will gaskets stop the oil leak? or do they make something for the booster I can replace? or worst case do I have to replace the whole pump ? Thanks keep up the good work

    Great writeup! Did this yesterday, no more leak. BUT, the screws where I made the witness marks near the shift selector! One broke inside the hole when tightening it back up. So, now I have one screw and the nut on the post tightened down. Seems secure so planning on leaving it that way as remiving the broken screw entails removing the big coolant hose, using drill and extractor, etc. Anyone know what will happen if this is not secure enough? Winky shifting? Want to know so I can decide when and if to go back in and fish out the broken screw.
