Hi all,

I have a couple pics attached of a broken vaccum booster (?) on my 2000 A4 1.8tQ. Is this the same part people have talked about fixing with just super glue, or is it better to replace the entire part? If so, does anyone happen to have the name/part number for this? Thanks in advance.

 

that would be called the suction jet pump. and yeah it looks like its about time for a new one for you

 

Thanks a lot. I've been researching all day and had just discovered the correct name for it. The part number is 058133753B for my B5, but I'm wondering if the B6 058133753D will fit the same. They look the same and both numbers are typically listed on eBay item info. I live in Korea and the B6 part will most likely be a lot easier to get ahold of. Thanks again!

 

What year is your car? From the pics I can tell you have a drive-by-wire throttle body and the false firewall/battery cover, so me thinks 2000/2001? Many of the B6 1.8T parts are interchangeable with the later B5 engine codes (ATW/AWM) because they used these platforms as a test bed for the B6 parts.

The necessity of the suction jet pump is arguable, but if you're not going to get rid of it entirely you should definitely replace that one.

 

Correct, I have a 2000 ATW. I'm gonna get ahold of the dealer tomorrow and see if they have either part. Right now it isn't even drivable, so what are my options, if any, for a temporary delete?

 

This thread is a good place to start. The info most pertinent to your situation is in post #4

 

Awesome. Thanks so much for the quick help everyone!

 

So, I got the new JSP installed and went ahead and replaced two of the lines going off of it while I was in the process. However, after starting the car and having it misfire, I realized that another line had broken.

After closer inspection, it appears that the "T" adapter on the evap system (line from the manifold that splits to the leak detection pump) had become brittle and cracked into a couple of pieces. Is there an easy way to get to the hose that goes up under the manifold?

 

Unfortunately there's no easy way to get to anything under the intake mani that I know of. Took me 15 minutes and two pairs of needle nose pliers to put a vacuum cap on my N249 when I did my SAI delete. Although I blame that on my big, manly hands
