My wifes '03 Beetle is throwing a fault code 17964. I did break the little nipple on the valve on the booster hose while changing the air filter and not catch it right away. I also had replaced the injector pump seal right about this same time. I replaced the hose a week or so later, but never got the full turbo back. The actual MAP (Group 11) is about 1/2 what Vag-Com say's they are supposed to be at idle. I am wondering what I missed or if the N75 just happen to fail about this same time. I was trying to see if I could get the MAP reading up by plugging the vacuum hose to the turbo, but it remained mostly unchanged. The rest of the vacuum lines including to the reservoir seem fine. I feel like this is something I missed from the previous repairs, but it all looks good. Anything thoughts on what I should check next?
Thanks,
Scott
