I have the same problem. Although my Passat pulls hard to the left.

I got the problem fixed by changing the servo. I will be writing the letter very soon and will let you know of the outcome.

Hi,
 
Thanks for the information, the VW garage recommended this as one of their engineers had carried out a private fix for another customer and this had seemed to work. Unfortunately this an very expensive experiment although it looks like I may have to take this route. The car is currently with an independent garage as VW franchised dealers hourly rates are too high for "experiments".
 
I will let you know what he finds.

P9, brake failure, brake feel (Re: Sevice Action P9: Sevice the Air Plenum) by davew5

Good news. After posting the above, instead of picking up my un-fixed car, I called the dealership and told them exactly what to look for (based on previous posts in this thread). They called back that evening, and told me they had been able to confirm the brake problem, that the drain hole was plugged, and that the brake vacuum booster would need to be replaced. Yesterday they confirmed that VW would cover the cost of the replacement, and I just picked up the repaired car (they replaced the brake vacuum booster and bled the master cylinder). So I am once again pleased that they got VW to cover the costs, but more than just disappointed that they didn't figure this out when I first took in the car with what turned out to be a serious safety flaw.
 
My main problems now are
 
1) I remain somewhat anxious about the brakes. They stop the car well, despite the well-below-freeing. However, the brake pedal feels different from the other car I've been driving --- it feels good when actually stopping, but when I'm stopped, if I keep pushing on it, it slowly moves toward the floor. The VW mechanic says this is normal for Passats.
 
2) that the water in the car is apparently due to a bad door seal ($1100 to replace it and do an extinsive carpet cleaning). I'm going to take the car to my regular mechanics to have the door seal replaced and perhaps a more modest carpet cleaning.
 
I'll also ask my regular mechanic for his opinion of the brakes, but out of curiousity, could anyone else with a Passat confirm that the brake pedal slowly moves away from you if you continue strong pressure when stopped and the engine is running?
 
Thanks for any data you can provide!

Sounds like the brake system still has air in the lines. I can only tell you my pedal DOES NOT slowly move to the floor while I'm stopped. I've never had a car that did that...ever.
 
IMHO, you need to find another dealer or repair shop. First, they don't know that the brake booster can suck in water if immersed from the clogged drain plug and now this about the brake pedal. Are we allowed to "call BS" within the TOS agreement here?

Hi Dave,
 
I also have just had an independent mechanic review the problems with my car (in the UK). Having been informed by the VW authorised dealer that the cars in the UK have different parts and that they had checked the plenum and that a blockage did not exist my local mechanic had approx 2 gallons of water emptied from the plenum when he cleared the blockage. He also then removed a significant amount of water from within the Servo - recommending that this be replaced as this is the second case of this that he had found - the other having significant internal corrosion following water in the servo.
 
With regard to the sinking brake pedal he again informed me that he has seen this several times on VW's and that the problems has normally been due to a problem with the master brake cylinder.
 
I am having both servo and cylinder replaced and will be raising this matter with VW (UK), my local VW retailer who failed to test for the condition when I had given them the copy of the US recall and a couple of UK Consumer bodies.
 
Watch this space.
 
Thanks to everyone who has contributed to this thread.

I like your idea about the ruined master cylinder. Very likely candidate for the sinking pedal problem.

shows that VW does not operate as a global unified company. Left hand knows not what right does. Which is fine when donating money but bad if you run corporation.

Might just be an issue of stonewalling on VW's part. The US recall wouldn't have happened without pressure from NHTSA. Maybe the UK equivalent hasn't had enough complaints to hit VW with a recall (if they even do such things in the UK).

Thanks for the note about the brake pedal feel. Based on this, my recollection that it was _not_ like this before, and a general impression that mushy brake pedals can mean bad master cylinders, I took the car to my regular mechanic (not the VW dealer). They confirmed that there was a problem, but were not able to identify it without really taking it apart and replacing pieces, and recommended I take it back to the dealer (just what I _didn't_ want to hear -- Piazza VW of Ardmore let me leave last August without replacing the Vaccum assist, then the told me this winter that they thought there was nothing wrong, until I told them exactly what to look for, at which point they did replace the vacuum assist, but then let me leave with something else wrong with the brakes... this seems to me like three life-threatening situations).
 
Anyway, I'm going to call VW of America and talk to them about the problem and having it covered by them if I go to a different dealer, and then hope there is another dealership not too far from Ardmore, PA. Until then, I continue not to drive the car. Fortunately my dad was able to let me use one of his cars. It's good to have family around at such times. Thanks also to Rod and everybody else in this discussion, for critically important information.
 
Dave
