SOURCE: 1997 VW Passat trouble code

Hi ejj509,

Both my 97 Passat and my wife's 99 Passat were throwing the same OBD codes you listed.

Both VW's had the same problem. There is no "quick" solution for the problem. I can tell you what I found, what I had to do and how I repaired both vehicles so they no longer throw this OBD error code.

I removed the black plastivc AIR pump and found that three of the six aluminum rivets which hold the AIR pump impeller housing together had rotted off so the case was leaking air. I went to a hardware store with one of the aluminum rivets I had removed from the AIR pump and bought six brass machine screws and brass nuts. I gouged the aluminum rivets out and replaced them with the brass machine screws.

After I had replaced the AIR pump in the VW, I cleared the codes and ran the diagnostics again.
It still threw the same codes!!!

Next, I removed the plastic top engine cover from the VW engine (VR6) and located the many air solenoids hidden under the cover. I went to a local NAPA shop and purchased an eight foot length of their smallest gauge neoprene gas line (1/8 inch ID).

I carefully removed each piece of rotted VW vacuum line from the air solenoids and replaced each rotted section with lengths of the new neoprene gas line. I had to follow out each of the old vacuum lines and replace them because they were badly deteriorated. This took about five hours to accomplish.

I replaced the plastic engine cover and connected up my cable from my laptop to the VW's computer port, cleared all of the codes and ran a new scan. This time the scan was clear! Woo Hoo! Apparently, the problem was both the leaking AIR pump and faulty, deteriorated (cheap) Volkswagen vacuum lines.

It was well worth the effort. My driveway has now become a bonafied VW repair shoppe.

SOURCE: VW P421 code

This is a common problem with V6 Passats. VW put out a TSB on this a few years ago.
The code is telling you that your catalytic converter (driver's side, I think) is bad. It's more than likely not bad.

VW put out a TSB on this a few years ago. TSB 05-13. The cause of the error code is basically an over sensitive ECU (computer of car/engine) and the fix is to have your ECU flashed with the latest and greatest software. Depending on your mileage they might do it under warranty - you'll have to check.

It's still possible that it might be a bad catalytic converter - and the dealership might try to tell you that either way. Call VW (1-800-822-8987) and ask them about the TSB (I couldn't find it online).

Tell the dealership you want the ECU flashed - it's much much cheaper than a cat. No sense replacing it if it's not bad
There is a federal warranty on catalytic converters - 8 yrs or 80k miles...

Hope this helps!

Trouble code p000a on 06 vw passat. can i drive with this code or will it cause more damage to the car


Cam shaft positioner malfunction. You can drive it. Just have bad gas mileage. Probably run rough to. If it starts making a bunch of chattering noise, time to have it fixed. I wouldn't take it on any long trips either.

Engine codes p0011 & P0034 on my 2001 VW passat I replaced the camshaft positioning sensor and not did not fix the problem can anyone help?


Well code 11 means the computer thinks the cam timing is too far advanced, which could be a timing belt issue.
Code 34 is supposed to be a problem with the turbo if your car has one.
Trouble codes seldom mean a sensor has failed.

2001 passat has loss of power, shaking and check engine light flashing


i had this problem on my 2002 passat. it was the ignition coils. first set were replaced in 2002 as a vw recall. second set (at 122K miles) were relatively inexpensive to fix. just one failed but it made the engine run really rough - my mechanic was able to move it from one cylinder to the next to get the problem to repeat.
