I have a 2004 Passat with the 1.8T engine, I was driving around town then heard a loud pop under the hood it sounded like a backfire. Now when ever I'm on the gas at WOT it would buck, sputter, and misfire. If I ease into the throttle I can still feel boost in 1st..2nd..3rd gear but bucks and...

I'm trying to figure out my stumble at wot. At idle my pc16 is a 35. Wot 3rd gear is between 60-65. It stumbles at wot. If i feather it it doesnt. Does anyone know.what this is disposed to run at? I have a 3 bar fpr at the moment. I was testing to see if.my fuel pump was shot. I replaced...

Hello, I was driving home from work today and on the way back i had to pass someone, so put the car in Tip downshifted into fourth no problem and passed the other car. As I upshifted from 4th to 5th the car started to go back and forth on its own, downshifting and upshifting until I let off the...

took my car on a 35 mile road trip today to go get some supplies and i noticed it has poor power when put er wide open. runs great part throttle and cruises right down the road at 80 but WOT is really weak all of the sudden. Like when you have it wide open, and start letting up it actually feels...

I was driving down the road yesterday and the car just died no clunk bang just lost power and died when I turn the key it sounds like the sylenoid is not engaging so I stuck it in gear and the car moves on the starter but won't turn the engine over. There is a connection from the tranny to the...

do you guys get a smooth acceleration on WOT (or at least pushing a bit hard) from low RPMs? My golf (4 cylinders) is smooth but the passat has always had a bit of a lag when I push the pedal hard at low rpms (especially 2nd and 3rd gear i think), almost like it lacks air or gas or something...

I have chipped (no idea what program, bought it chipped) 1.8t, with 93k on the engine. Tonight, I did a 2nd gear pull, spiking about 19psi, but when I hit about 5k rpm, there was a huge knock and I flipped out and let off. What could be causing that? I was at optimum engine temp, and use Mobil...

2000 ATW passat with AEB conversion. cant seem to figure out the cause of my overboost issue.At WOT car will spike 15-17 psi, drop to 5 and surge back up and down.. ive changed my N75, tested for a boost leaks, and recently tried unplugging the charge pressure sensor. when i did so the car...

I have a 2000 ATW passat 1.8t, swapped a AEB motor but car is running off a stock ATW ecu. At WOT the car will spike 15-17 psi, then drop down to 5 and then back up to 15-17. IF held at wot the car continues to boost up and down

Hey all, been reading a lot on this site for the past 2 months, bought my 2004.5 1.8t 5spd fwd Passat from a dealer at about that time. I absolutely love the car, aside from the tragedy that happened 4 hours after i bought it (pressure plate exploded into 5 pieces, as well as the master and...

okay so im stumped guys, when i go into WOT, my car seems to spike and drop rapidly around 15psi. i took a video but it doesnt really show it all too well... my boost gauge will just go from 15 to 12 to 15 to 12 like 10 times a second when im getting on it. i'm pretty sure i have an exhaust...

03-v6-mt--- i get a bit of a hesitation on WOT sometimes. it happens when smashing the pedal right after changing gear (so like when RPMs go from high to low (change of gear) i get a dead spot when pushing on the gaz pedal again). I put some techron regulary and keep up with maintainance. air...

I put my foot down in 2nd and as it gets to 3000 revs the car hesitates boosts and pulls back boosts then pulls back. Could anybody tell me what it is? car is a 98 aeb 1.8t with a k04 installed and mapped 2 years/30,000 miles ago and i havent had any problems since until now. We're having a bit...

At WOT the RPMs bounce a little, I mean a little little. Between 3.2k and 4.5k it does it, after that it doesnt do it. I recently put a K04 in and the N75H valve. I am still on stock FPR, ECU and injectors. Is it possible the ECU cant keep up with the new turbo? Everything is hooked up...

I didn't get any cels until I tried to diagnose the problem by repeating it over and over. Then I got the emissions workshop flashing cel and then it went away after like 30 sec at idle. There are no misfires under normal driving or semi hard acceleration. 1.8t atw 125000 mi

My car is making just way too many noises. Someone please help me get rid of one of the newest annoyances. Car: 2003 1.8T 5spd wagon Engine/exhaust mods: APR chip, N75J, K&N drop in filter, TT DP 2.5" with borla muffler The noise can best be described as a mechanical buzzing from the...

Hey guys, need some advice, wot would happen if the spring in your dv was too strong? would it lower your boost levels or not? I have a hyperboost dv from stratmosphere and pu in a 1/2 inch thick washer as i was trying to check if dv was strong enuf, i still boost to about 10psi which i';ve...

Ok, this is the second time this has happend and almost got me killed this morning. I was crossing oncoming traffic to pull into a gas station when my Passat seemed te hesitate. I mashed the pedal to the floor to avoid a head on collision, but when I released the pedal the engine continued to...
