I hear a similar sound as well, but I figured out that it was my wife who wants a new car.

White smoke indacates unburnt fuel. With an ohm meter disconect the wires on the glow plugs Check each one for resistance. About 1 ohm. They should all read the same. If not you may have found the problem.
Additionaly my VW TDI the glow plugs all were within spec but it still through a code. Along with rough idle and white smoke. Replacing the glow plugs solved the problem.
As I understand it. The glow plugs remain on after starting for a time.
Emissions no doubt.

glow plugs should be fine, I have no codes and the car starts excellent except for the shacking(half a minute). On my tdi the car ran fine even without the glow plug harnes on, anyway I think the GP-s are helping under 38- 40 degres F.

Just a little somthing.. It took 1 month for all the air bubbles to leave the air lines in my car. It looks like it is a self purging system but I swear I watched the same air bubbles circulate around the IP. My wife also noticed that the car ran better above 1/2 tank.

I to had simular problems (white smoke). In the end I replaced the fuel lines & cut off solinoid, came up with the diesel purge proceedure, and started using redline 85 plus diesel fuel enhancer. It took a month for the car to really start to run good. The car now runs so good it sounds like a 2004 cdi.

Other factors could be the fuel at the pump and warmer weather but I will know next winter. We have had some cold days recently but the car still purrrrs.

could you tell me where the cut-off solenoid is and what does it do? Tanx

This thread should answer your question.

One possibility is a bad engine coolant sensor. It may tell the computer the engine is warm, when in-fact its cold. This will cause the computer to misadjust the idle control.

I had a similar problem with my car recently. I have the wiring diagram and was able to diagnose it by measuring the resistance of the coolant sensor and determining that-its defective. Changing the sensor fixed the problem. My car, unlike yours, provides very limited engine codes. Defective coolant sensor is however one of the provided codes. However I also had no error codes whatsoever.

Perhaps someone with a wiring diagram for your specific car can help you out. Alternatively, as a substitute to the service CD you may want to subscribe to "ALL DATA" - http://www.alldatadiy.com/ - its around $25.00/year/Model car, and has the same info as the service CD. That's where I get most of my info, including diagnostic procedures, electrical wiring diagrams, etc., etc..

Much cheaper than having the dealer diagnose the problem.

Got the injection pump rebuilt by Gus at Pacific Fuel Injection Service. He did a beautiful job. If he is half as careful with the inside as he is with the outside than this should be a perfect pump. He showed me the machine that he uses to check the flow to each cylinder and and the average flow. This place is a great resource if you need a rebuilt pump or injectors. Did it faster and for less $ than his estimate!

Brought it back to the dealer who installed the new pump. This did cure the excessive black smoke with WOT. But the damn shake is still there when you put the transmission into N or P. This is the problem that I brought the car in for and it still hasn't been fixed.

It also seems a bit rough with a faint "Wah-Wah-Wah" when appraching a red light with the foot off the accelerator pedal.

Any suggestions?

D-zel, any progress?

YES the stumble or fluctuation in rpm's just off idle when decelerating... finally someone else noticed that.

last time that the car was shaking it was 90 degrees outside, ever since than no more shaking. The shop told me to bring it in whenever is going to do it again. So probably april or may....
