Car Screeches when hot by joker55

Hey guys
 
wondering if you can help me out, ill try to make this as short as possible
 
I've got a 1999.5 Jetta, Auto, with 199,xxx km on it, a few months ago i noticed a "screeching/rattle" noise coming from underneath the car, it is noticeable after the car has been running for more then a few minutes or has had a good run on the highway
 
it does it when i have the car in Drive, and foot on the brake, i can hear this noise coming from underneath the car, closest to the front, i'd say it was coming from where the downpipe/cat is, also, ive put the Ebrake on with wheels chocked and got down beside it and can hear the noise, it goes away slightly when i put it in park/neutral, i pop the hood but dont hear anything in the engine bay
 
anyways, i went to the mechanic and asked if it was the Cat (i had a similar noise about a year ago and had VW replace it under the warranty and didnt really notice it anymore, probley cause it was winter time i.e windows up all the time) he told me that he suspected that it was the heat shield on the cat.......so i cut it off (my warranty was up anyways)
 
noise was still there
 
i go to a muffler shop and they said that it was the bracket where the resonator is, the exhaust was vibrating and going to the front of the car where the flex pipe is hence it sounds like screeching......so had that replaced
 
noise is still there
 
this noise is driving me nuts, simply because i cant figure it out, i know its not my serpentine belt or my tensioner, i had my timing belt and water pump done not too long ago because of another noise, so i dont think its that
 
has anyone had this problem or now what this problem is? i dont want to just start throwing money at in hopes it will stop, i'm just concerned its going to become something worse....
 
any ideas?
 
thanks in advance

You'll need someone under there with a mechanic's stethoscope. Sounds like it's vibration-oriented, not a belt noise.

Well you'll need a VAG scanning tool to find out what's going wrong with the Throttle Position Control---there are various components and possibilities here.

jerky acceleration on 08Jetta 2.0T wolfsburg by gophergirl

All of a sudden; since my 15K check my jetta will lurch as I take my foot off the brake. Happens both while backing up and also going forward. Only happens after engine is warm. I can not seem to get a smooth 'off the line' start.
 
Any ideas? Help this is driving me crazy. I know it isn't me or my driving habits as it only happens when engine is warm. Never when it is cold.
 
HELP

The only thing all of those codes have in common is a ground connection. I would try cleaning all grounds you can find.... pay close attention to the grounds for the engine-computer
