Passat (B5) :: 1999 1.8T - No Power But Has No Codes And Makes Boost
I'm fighting with my latest purchase, a '99 Passat 1.8T AEB with the Tiptronic trans. I'll just get right into it. The car has been gutless since the first time I drove it, thinking it was the DV, I talked the seller down on price and took the car home. It wasn't the DV... so I checked all the basic things I could to try and find an issue. This included checking for vacuum leaks (only found one, fixed it), fuel pressure (50psi at idle with hose connected and 58psi disconnected), boost (5-7psi with wastegate accuator connected, but only spikes to 10psi between shifts with it disconnected), and compression test (180psi for all cylinders). None of the tests pointed anywhere, but the spark plugs did show signs of a lean mixture (white and chalky).
With the basics out of the way I bought an ebay VAG-COM cable and VCDS-Lite from Ross-Tech. After setting up the VCDS-Lite software I began with a MAF test, which showed a high of 96g/s, lower than the expected 120g/s. I grabbed a different MAF sensor and tried it, but the results were almost identical. Then I looked at throttle angle, this was 86.8 degrees at WOT, which seems to be average for AEB engines. However, at mechanical WOT VCDS-Lite says that it is only at "Part Throttle". I'm thinking this is just an inconsistency with the software, but I don't know. The last thing I checked was fuel trims, but they were slow to respond, only showing 0.0% for most of the drive and eventually changing to 0.8%. From what I've read this seemed normal.
Any other tests I can try? I'm leaning towards the MAF sensor being the culprit, but I swapped it with a used one and saw no change. Maybe both were bad? Can the throttle position sensor cause this? I read an older thread where the angle sensor said WOT but not the position sensor.
Passat (B5) :: 1999 - Check Engine Light On With DTC Codes / Misfire After Startup
The check engine light on my 1999 1.8T Passat is on. It started with a little miss right after startup. Then in neutral, after revving the engine to say 1,500 rpm and letting off the gas, it would nearly stall. I plugged in an OBDII analyzer and came up with codes P0102 MAF or VAF circuit low input and P0304, Cylinder #2 misfire. I replaced the spark plugs, as they were old anyway. Still the same symptoms. Then I replaced the mass air flow sensor.
The check engine light still went on after it was cleared, except this time it was P0302, Cylinder #2 misfire, P0102, P1613, Auxiliary inputs aux. outputs control, and P1426 Mfg. Control/auxiliary emission controls. Soon after, the car started running fine on it's own and I again cleared the codes.
Then a day later, the check engine light is on. This time, it is only the P1426 - Manufacturer control auxiliary emission controls. The Bentley manual calls it Tank Vent. Valve Open, which doesn't mean anything to me and the Bentley manual is of no luck. (The error code almost implies that it is the famous loose gas cap, but I have checked that - unless the gasket is bad). FYI: I have 99K miles on the car.

Can dealership diagnostic tools read ABS/ASR fault codes, or if those codes are even stored?
View 1 RepliesPassat (B5) :: CEL Accompanied With Engine Codes
I just got a 2000 V6 Passat Wagon. The CEL light was on when I got it though I bought it knowing this. The battery was bad when I got it and I replaced it. After installing the new battery . . .. . starting worked only intermittently. It got worse and at one point I had to hold the key to the start position for about 5 seconds before the starter would even engage. Now it won't start at all. I pulled the codes (shown below) when I first got it but did not give it much credence . . . I wanted to clear the codes and drive it and re-look at the codes. . . . but I have not been able to drive it.
Other observances. . .. not sure if they are related to the car not starting:
Windows, sunroof do not roll up/down while electronic locks work. The driver side window was down when I got it and I read somewhere on this forum to use the key to raise it. . .. it worked. Alarm does not work. Radio works. . . . I found it odd that though the battery was taken out for more than 12 hrs. . . . The radio code was not required. Dome light works intermittently.
I have checked every fuse and they are all good.

Passat (B5) :: CEL Codes P0102 And P1137?
So my check engine light came on (2000 Passat 1.8T) and I have one of the generic code readers and got this:
1. P0102
Powertrain: Mass Air Flow (MAF) Sensor Circuit Low Frequency
2. P1137
Powertrain: HO2S Bank 1 Sensor 2 Lean System or Low Voltage
Now last time I had the car in they said I needed to have my throttle cleaned, but I just didn't have the time then. Could this be the reason or am I looking at bad sensors? It's weird, because the car isn't really driving any differently. I have had one side effect though, my turn signals won't come on and the hazard lights will come on, but not always. All the interior lights, headlights, brake lights are working fine.
Passat (B5) :: CEL Came On With Two Codes P0B33 And P1136
Alright so my check engine light had came on today and i got home and scanned it and got 2 codes which were ... P0B33 AND ALSO P1136
What codes are these ? and what is causing them to give me a CEL ? and how could i fix the problem ?
Passat (B6) :: CEL Comes On / Codes P0441 And P0171
So one day when I was driving, the CEL comes on, and then I go to autozone to get my free diagnosis. I got codes: P0441 and P0171
My engine is running fine and everything else seems to be in order. However, I have to get a new canister purge valve and new oxygen sensors, in order to be in the clear.
For the Oxygen sensors, I have AN IDEA of where they're located; somewhere underneath the car, by the catalytic converter (the converter is in between the two connectors, apparently). I have yet to do this and would like some opinions on what to do for it.
For the Canister Purge Valve, I have no clue where to look. I pop open the hood and I notice a diagram with labels. Great, but there are just too many other pieces to look at...I do not know if it is visible as soon as I pop open the hood, or if I have to dig deeper, or even if I have to remove the fancy plastic thing that covers the engine.

Codes P0491 and P0492 ... The Air pump works, so what's the problem? Perhaps the combo valve? If so how do I check this?

My 2.0T CEL flashes on start up for about one minute as the motor shakes and sounds like an exhaust leak, then it levels off and runs fine and light goes off. No codes recorded. I have changed plugs and coils and PCV valve.

I have no clue what is wrong but I have an exhaust leak and when I am accelerating I can hear the loud shhh sound like the turbo is leaking but I still have power like normal.
Passat (B5) :: All Sorts Of Engine And Transmission Codes Came On
Where do I start, 97 Passat VR6 Wolfsburg Edit, 01M trans with AAA engine. 140000 miles. Here is what it is doing! Starts and runs fine.....until I stop, turn the car off, let the fans cool the engine, and then try to start it up again. Then All breaks loose. Car is running rich, almost dieing, sputtering, throws ALL sorts of engine and transmission codes. Everything from MAF sensor to misfire to trans solenoids, I mean the codes are all across the board.Then I can take my generic scanner and reset the CEL and all is good for a couple of miles.
Now, here is what I have done to the car:Tranny: new synthetic oil and filter, removed, cleaned and replaced the valve body with new solenoids, and complete wiring harness, NEW Transmission Control Module. All new 3 New trans sensors, 1 Trans Speed Sensor and 2 other sensors, g38 and g68 i think.
Engine: New, Bosh,Synthetic Oil and filter, New Ignition Switch and Key and tumbler.New Valve Cover Gasket,Bosh, Plugs and New Bosh Plug Wires., Brand New Vw ignition, Brand New Bosh, Auxiliary Water Pump and rubber gromets. New tires,...Pulled floor pan carpet out and dried up mat after the rain where my daughter left the passenger side window and sunroof open. I will try to drive it today without turning any of the lights on the dash on to see if possibly I have an electrical issue with the dash and lights or something.

View 3 RepliesPassat (B6) :: 3 CEL Codes - Car Wouldn't Start After A Fill Up
As I said before I thought my emissions valve was bad because the car wouldn't start after a fill up but the coils were bad too so I took them in to be replaced first since I didn't have a CEL for the valve. The CEL went away till today and when I pulled them I got these 3
P 0441 EVAP emission purge flow fault (why it wouldnt start after a fillup)
P 0171 System Too Lean (Bank 1) (probably from when it started like crap)
P 0299 Turbo underboost
The third one is the one that's getting me. Ive had the evap core go bad in nearly all of my VW's so im familiar with the codes that go along with it, is the 0299 a part of it as well?
