I don't think that's the EGR valve that the shop is talking about for that kind of dollar figure. More likely the injectors or injector pump....accordianman

Sounds to me you blow by. Thats when either rings on the pistons are worn letting oil pass by or you have a scorned cylinder which also is letting oil get by. Should get a compression check done to make sure.

SOURCE: 2000 TDI - Lots of white smoke at cold start.

Sounds like your injection pump timing is off, an injector is leaking or a bad seal on your IP.
VW dealers have a horrible reputation when it comes to TDI's. Check out the posts over at www.tdiclub.com Those guys are very knowledgeable - and the first thing they'll tell you is don't take it to a dealer.
You can probably find someone in your area that has a copy of Vag-Com (scantool software that vw uses) software that could look at your timing. It definitely sounds like your dealer was throwing parts at your car because they didn't know what your problem is. If I were you, I'd copy and paste your post from here over at www.tdiclub.com

SOURCE: p0171 lean code will not go away. changed fuel

Double check the very small hose that comes off of the manifold, since it sits so close to the manifold, I would not be surprised to find it frail and broken.

If you have tried everything else, have you had the code cleared after you changed out the parts? try having it cleared again....

What is a egr valve


  1. Install a tachometer on the engine, following the manufacturer's instructions.
  2. Detach the engine wiring harness connector from the Idle Air Control (IAC) solenoid.
  3. Disconnect and plug the vacuum supply hose from the EGR valve.
  4. Start the engine, then apply the parking brake, block the rear wheels and position the transmission in Neutral.
  5. Observe and note the idle speed.
If the engine will not idle with the IAC solenoid disconnected, provide an air bypass to the engine by slightly opening the throttle plate or by creating an intake vacuum leak. Do not allow the idle speed to exceed typical idle rpm.
Using a hand-held vacuum pump, slowly apply 5-10 in. Hg (17-34 kPa) of vacuum to the EGR valve nipple.
  1. If the idle speed drops more than 100 rpm with the vacuum applied and returns to normal after the vacuum is removed, the EGR valve is OK.
  2. If the idle speed does not drop more than 100 rpm with the vacuum applied and return to normal after the vacuum is removed, inspect the EGR valve for a blockage; clean it if a blockage is found. Replace the EGR valve if no blockage is found, or if cleaning the valve does not remedy the malfunction.

    Find the EGR valve on the intake and locate the vacuum hose that is connected to it. Start the engine cold and as it warms up, pull the hose off and if it idles and drives fine, the EGR valve is bad and needs to be replaced. Please rate me on this answer.

    Idle seems a bit high. Need to know how to adjust and what RPM


    There are a couple of things that come to mind. One is make sure the EGR Valve and intake manifold are not carboned up. I normally have to clean them every 60 to 80,000 miles. It will actually close up with Carbon and restrict air flow and make the EGR valve malfunction. 
    Secondly, the diesel pump may just have a lot of wear and it is putting out too much fuel at idle. The only way this can be checked is by the dealer with a VW specific scan tool such as VAG-COM. With this tool, you can go in and look at the the pump timing and start injection quantity. 
    I have the start injection quantity many times but you have to have the software and login to get the readings. Most dealers will not do this but would rather sell you a pump if it is off.
    Remove the hose from the intake where it connects to the EGR valve and look at the inside with a flashlight. See how much carbon is accumulated. This may not solve this problem but will help with starting and performance issues if corrected.

    Good luck and hope this helps. To adjust the Idle, it needs to be programed in to the ECM so i am thinking that it's a Carbon issues that is restricting the air flow which the ECM is compensating to keep the engine from stalling.
