Default 2006 Jetta EGR valve?

​Hi guys, my 2006 Jetta is throwing the following code I have cleared it and it comes back instantly. Did some searching and from what I can tell I most likely have to replace the EGR valve. can some one confirm this for me.



I did also get the following 001027 - EGR Valve (N18): Malfunction but hasn't come back yet after clearing it once tho I haven't been driving the car.





Thanks

Dieselfueler is correct....spend the money on a tune to delete the EGR and block off instead of replacing the EGR

I just blocked mine off and you would not believe the power & fuel economy difference!! I did mine because of a problem I was having but am going to do it to my wife's car also just to prevent a problem. I wish I would've done it years ago! I got a blockoff plate from dieselgeek.

I'm not convinced it's a bad EGR... at least not yet. Last month I had this code and driveability issues outlined here:
001027 - EGR Valve (N18): Malfunction
P0403 - 000 - - - Intermittent
And these codes are set when disconnecting the EGR (which corrects driveability):
001031 - EGR Potentiometer (G212): Signal too Low
P0407 - 000
If it's a bad ground, non-EGR codes will also get set. If not, then trace the wiring harness back to the fuse box and look for chaffing.

I finally got the EGR off last night. it's not all that dirty, deffinatly not plugged. I will trace the wire back to the box and look at the connection when I get home.

Originally the light came on the day after I had changed all of my filters. it was raining/snowing and cold I had just driven 2.5 hours (the return section of my trip) back into the city and stepped on the peddle to go it had no power. CEL came on.

At the next light stepped on it and it went. the CEL did go away for a while then came back. it drove ok for awhile then sitting at a light it started to sputter died then would not start. after about 5 tries it started. drove it back home (less than a block) left it for a couple of days. It then ran fine for a couple of weeks.

it started sputtering again that's when I parked it till I got the codes read.

If it dies at idle, then it could be a bad EGR. In the meantime, just disconnect the electrical connector on it. It will set a code, but the driveability issues should cease. The exception being if the valve stuck open and flooding the intake with exhaust.

ok I've replaced the EGR valve with a new one. decided it was probably better to replace then to block it off as I live where it gets -40C regularly..

as soon as I cleared the fault code it returns. I have noticed that it idles alot smoother now.. tried to clear the code with and without the engine running same thing. it returns right away.

my '06 tdi has a loud hiss coming from under the car. I chased it to what I believe is a EGR actuator valve. I already have a tune in it from kerma so can someone point me to the "how to" to block off the egr?

I've also pulled the airbox and looked at the one ground point. (looked ok.) thinking I'm going to pull the battery box and look at the connection there.

any other ideas why the code wont clear?

A "tune" is where the engines operating parameters stored in its ECU are modified from those of the manufacturer. Kermatdi is one and Malone is another of the popular TDI tuning paradigms. A local shop in your area will use either of the two and will "tune" your MY06 Jetta's 1.9 diesel. Cost varies but USD $300 or so is customary.

Our MY06 Jetta received a KermaTDI tune years ago when near new, at 10K miles or so. The tune level chosen was 1+ which is ever-so-slightly more aggressive than the stock VW tune. About 35-45ft lbs more torque, and a slight HP increase without a fuel use penalty.
Fast forward 8 years and 140,000 miles ..... the TDI charges on ...... A nice, fully optioned, under the radar, quality sedan.

Go for it ..
