Thanks Shipo, I did take it to VW dealer, they told me it could be control unit, they changed that with no luck, suggested injector changed all of them, cost me over $2000. Now they are telling me "it could be" gasket and need another $3000 for that cause block might have crack as well.
Still love my VR6, is it time to look for another motor or shall invest some more on this? Bad thing is they do not know if that is the problem for sure or not.

I have a pretty fair amount of engine experience and I have NO IDEA how they can draw a line from running rich enough to cause significant fuel dilution to a head gasket and/or a cracked block. Something smells fishy, very fishy.
 
Regarding what they've told you and what they've done and charged you for, ummm, it sounds like they are totally incompetent and simply throwing parts at the problem in the hopes that they'll get lucky. Were I in your shoes I'd call around to various VW dealerships and/or Independent shops that specialize in VWs (and other European cars), and ask if they have a technician on staff that is certified on the fuel systems of the 1990s vintage VR6 motors.

Thanks for quick useful response, in the mean time I have been busy looking for used motors...kinda hard to find reasonable millage VR6 motor. Kinda hesitant to put more money on my motor...also dono how good I'll get used one. A word of advise?

This is a tough one...
 
Under the heading of, "The devil you know...", your current engine sounds to me like it has a fairly simple problem, that said, your mechanics have proven unable to properly diagnose what's wrong.
 
Under the heading of, "The grass is always greener...", you should be able to find a good condition 1995 or older motor (I believe that 1996 was the start of OBD-II for the Passat) with less than 100,000 miles on the clock for resonable money (i.e. less than $2,000). The other side of the coin here is that you have no idea if the used mill has been abused and what new problems might pop up.
 
Under the heading of, "A sure bet...", you might also want to consider a rebuilt engine. Here is one source:

I hope some of this helps.

altair4, Thanks for the detailed response.
 
Here are some answers.
 
1.I have done 8 oil changes...religiously around the 5000 mile interval ( give or take 100 miles)
2.Except for the one occasion when I went to Lube Express, all other changes were at an authorized VW Service center. 3.They always used synthetic oil although I donot know if it was the right specification.
My driving conditions are a mix of city and highway driving 50:50
4. I am not much of a hard driver. however, I do cool the engine after long drives ( 2+ hours)
 
I have one further question regarding the Timing belt. Is it possible to just have the VW service guys check the timing belt to see if it needs replacing?
 
Regards,
Vinay_S

#2244 of 3340 Replacing injector #3 on 06 Passat by spawnman

Jun 15, 2007 (10:04 am)

So the dealer finally figured out the misfiring issues and will be replacing injector #3. My concern now is what is involved in doing this? Will the engine ever be the same once it's been opened and but back together? Or is this an easy fix and and any "mechanic" could do it? I guess I'm asking should I be concerned when I get her back?
 
Thanks

Replacing the injector doesn't require opening the motor. It should be fine, all the injector does is squirt the gas in from the fuel rail.
I believe that even with the Direct Injection, it is still a matter of swapping a component. If your car is an '06, I would think it would be under warranty.

Generally speaking, replacing a fuel injector is about as simple as replacing a spark plug. Don't sweat it.

I don't know if VW still has their maintenance schedule on their website or not. If you were to read it, it would say to have the timing belt checked at the 40, 60, 80 thousand mile services. Then it suggeted a timing belt change at 105K miles. Interestingly, Bentley Publishing, the company that prints the service manuals for VW, has an editorial sugestion to check it every 20K miles, and replace it at 60K.
 
So you have to ask yourself in your best Dirty Harry voice, "so...do ya feel lucky? Well, do ya?"
