Passat (B5) :: CEL And Code P1596 - Noise Coming While On Boost
Jul 24, 2007
Ok, I just bought this car a month ago, and I get this code coming up intermittently. I reset the code, and it will come back after driving a while. 2002 passat 1.8t 5 speed. It seems like it comes back when I roll backwards a little bit (like from a standing start on an incline) right before taking off. Could this be a leaky throttle body to inter cooler hose? Seems like the engine might move more while taking off from a backwards rolling start due to the torque. Also, I hear a lot of noise while on boost coming from the drivers front corner of the car, although it doesn't throw a code while on boost.

I currently have the P0299 code for underboosting. I am pretty certain that i need to replace my wastegate actuator because i can hear it rattling on deceleration.
My plans are to replace it at the same time I replace the timing belt since it would be a decent opportunity to remove the turbo to change the WG actuator. However, I still can't figure something out. When I am starting to accelerate from a stop in 1st gear (and only 1st gear), there is a loud screech, lasting only a second, coupled at the same time by a quick and noticeable loss of power; as if boost was released. I typically shift out of 1st within 2500-3700ish rpm, if that makes any difference.
From what I have researched, this sounds like the turbine making contact with the housing. I may be wrong, but that does not add up to me because I am only experiencing this problem in 1st gear. We are talking about a 2003 B5.5, Engine Code AWM. No mods, 100% stock.

I lost boost, went from being chipped at 16psi to 7-8 with a check engine code and a high pitch noise. Now is the secondary air pump connected to the turbo in any way. It just happened and I'm working on getting the code read. Just curious if my pump is just bad, what im figuring.

Sudden power loss experienced. CEL (Check Engine Light came on) and Glow Plug Light was flashing. Power loss is severe so really can't drive it anywhere. Turbo Failed at 5500 miles.
Mechanic quote: "Found code P0299 for turbo power under boost. Removed upper engine cover and intake hose. Checked turbo shaft and found play near intake side of turbo. Removed lower engine shield and lower hose to intercooler. Checked for metal. Contacted VW and created VTA. Instructed by VW to replace turbo. Did."
Sounds like service manager abbreviated when entering into the computer. In any case a shame that this car was in the shop for more than a week while the dilly dallied and waited for a turbo to be shipped in.
Some earlier turbo-fail threads from last summer stated dealer told them "bad batch" of turbos was being experienced by VW. Believable, particularly if they're banged out in China? Let's all hope it was a bad batch.

I have a 02 Jetta TDI with 186k miles. Couple weeks ago it all of a sudden started making boost noise when I was driving to work and then on the way back I was getting almost no power. Like over boost and under boost issue, so I assumed it was the MAP sensor. I got busy next couple weeks and then tried to start the car but now the car is not starting.
Completely charged the battery so its not the battery. Looked online and it seemed like it could be the 109 relay for the fuel pump. I pulled the back seat off and I can't hear the fuel pump prime up. I got a new relay from auto zone and put it in, still same thing. I don't want to have to replace the fuel pump only to find out its not the fuel pump. I ran the code and I'm getting the P1556 code (charge pressure control negative deviation).

Our car has been throwing a low boost code. We replaced the dv valve, pcv was just replaced but code still comes up. It's been making this noise that has arised with the code. It will do it down hill from 1500 to 2400. Just a constant rattle.
What do we do from here? Fix rod? New wastegate? New turbo?

When I shift under heavy boost (stage 1), there is a very distinct noise, imagine sucking in super fast, to the point where it kind of mid pitch moans, and speed it up to only a bit of a second. Its very hard to explain! is this a normal noise? or should I be removing the DV asap?

Dealer says the "gas cap" code keeps coming up. Won't share the number with me.... I've tried two new OEM gas caps, fuel & air filter replacement. I keep paying to get it reset. It keeps coming back on. Clueless VW mechanics... What else it might be?

Code p205b? 2012 TDI with 52k miles. Cleared code the other day and it came back on this morning (I have had luck clearing 2-3 codes in the past without them coming back, most likely due to condensation or similar on various sensors). Looks like it has to do with the AdBlue system with some other searches but I am looking for specifics like PNs to replace and whether the emissions warranty might cover this. I only purchased extended powertrain and it looks like it would only be covered under the highest tier extended warranty.

Well my car is listed above it has 99 k on it now.. For the last few months the check engine light had been coming on and off.. It usually happened after I put gas so I figured it was the gas cap... Till yesterday I had it scanned at auto zone and gave me the code listed above... Don't know how to go about it.. I've searched some and found that it could be a cam sensor of some sort or a follower ( spelling) ... Is it a easy fix .. Like I said light goes off and on.. Doesn't stay on always.

EPC light coming on intermittently on the morning causing loss of traction control and cruise control, occurred 4 times in 6 months. No fault code logged in, no CEL in dashboard. The dealer checked for logged codes, none. Also had one time the low coolant level display in dash all during one ride to work (30 km) the coolant tank was full and even if I was cycling the ignition switch it was still displaying it. Back from work it was disappeared and never came back on. all EPC light coming on at morning, and ok when coming back from work 9 hours later. Any clue on this?

Having trouble with this code. Replaced stock air filter with aFe filter 10,000 miles ago. 20,000 on truck. Threw code sunday dealer replaced filter with stock. said code may come back. which it did 5 miles later.
Edge CTS says max boost is at 22 psi. Is this something i will live with or indication of something else?

P0171 system to lean.
I already replaced the MAF so what else could it be I cleared it once and the cel came right back on. I have a stasight pipe from the catback on my car and the cabin started smelling like burning plastic and eggs every time I accelerate. I'm going on a road trip tom and was wondering if I'll be fine. The car has a bit more noise coming from the engine the usual more like a swiping tapping noise

I disconnected the red wastegate hose in order to address a low boost high EGT issue. This seemed to fix the boost / EGT issue for the most part, but now I get this P1249 code. The first time I got it I saw boost at about 20 PSI. I figured I would try to keep the boost below 20 in an attempt to prevent the code.
I managed to capture some log info when throwing the code. The highest boost reading I saw was 19.58. Pretty close to twenty but I question if I even should be getting this code at this level of boost?
Here's a chart with the boost info. Yes I still have a very bouncy EBP and hope to track that down at some point as well....

I'm having a little trouble with my 05 Excursion 6.0L .... We took off camping the other day pulling our 30' camper and the engine light came on pretty much as soon as we hit the highways. I checked my Dash boss and it came up as P0299 under boost condition. The truck never skipped a beat. The boost gauge never dropped and it seemed to have lots of power. Actually I've noticed too much boost while pulling. It's climbed up to 36psi before and was still climbing when I backed off the throttle. I'm thinking the turbo is fine but not sure what to check next.

P0237 code. The truck is a 2003 f250 with an edge evo . The truck will run great then throws this code and won't build boost of over 11 psi. Now it even drops it right off to 0. I replaced the map sensor a month ago and doesn't seem to have fixed anything.

I've been experiencing this problem since I had the car but it gets me around fine and has been getting 30mpg; hasnt bothered me all that much but i'd really like to get the problem solved... A few months ago I hooked up a boost gauge and she would not boost beyond 2psi. Since then I've changed the air filter, spark plugs and found a wire that was un-plugged causing the engine light to stay on. Hooked up a scanner and no more codes.. But the car still doesnt pull the way I'd think it should and with a stop watch hits 60 in no less than 9 seconds (shouldn't it be around 8?). The WG actuator rod is free, but I disconnected that electronic control solonoid, drove the car hard and there was no change in performance or driveability! One thing I havent done is change the fuel filter so I'm thinking maybe it's in a limp mode and awaiting the fuel filter to be changed? But then wouldnt a code come on if this is the case?

My CEL came on a few weeks ago on my 2010 gti, I scanned it and got a code for evap (P0456). I figured it was from filling the tank while the car was running, so I cleared it and went on with my week. About a week later it came back on and when I scanned it, I got the same thing. I haven't had time to smoke test the system but the last couple days i have heard a clicking/tapping noise coming from the rear passenger side of the car. Could the flapper in the filler neck be malfunctioning or gas cap be leaking.

My 05 excursion died on me a couple weeks ago. First it threw a p2290 code for low injection control pressure. It did this a few months ago and had no problems. Cleared code and did not come back until now. So I cleared the code. Drove a few more miles and lost all boost pressure. Still fires up and runs. It does run a bit rough but only a little bit.
I replaced the oil cooler, did egr delete, and put an IPR remote oil cooler and full flow coolant filter on it few months ago. Since it died i pulled the ipr valve and it looked good. I put a new screen o-rings, and wiring pigtail on it since it was out. Put back together and still no boost. I really did not figure that would fix the boost issue but i wanted to make sure the screen was not clogged or torn.
Truck will fire up cold and warm with no problem and run. The hose from the map sensor to manifold is good and i put new clamps on it.
2005 6.0 with 95,000 miles.
ICP duty cycle = 0.29
map kpa = 102
Injection control pressure = 5.91 MPA
