Post this in the technical section, we'll help you get it fixed.

Start a new thread with a full vagcom export. I'm not convinced it's the injection pump just yet THOUGH it's very very possible.

Your right, it was not the injection pump. It was only the in tank fuel pump. We had it towed to a guy who's suppose to know these and works exclusively on European Vehicles. It was much tougher than I thought it would be to get somone who even wanted the job let alone someone who knows what they're doing. I called 10 different diesel Specalist places and almost all of them said it's a WHAT? NOPE! We only work on Domestics! I finally called The Diesel Doctor in El Cajon and they too said NOPE they only work on American Diesels, but they did refer me to Pacific Hwy Auto Repair we had it towed there. The Repair Bill is up to $3300 so far and expected to go much higher, and we want to get an annoying oil leak fixed too that started around 160,000 miles.

The truck already has $1200 worth of Brand New Injectors, will have a new fuel pump now.

People are clueless with these, it is unbelivable how cluless everyone is including many exclusive European Repair.

We had a diagnostic done on it at Autohaus Stebel in El Cajon & when I explained what had happend thus far, the Mechanic told me Quote: I don't work on these, "I'm only working on it because I'm forced too as I work here but I hate these!" Can you imagine? Then he started talking he thought it may be the DPF!! Are you kidding me? THERE IS NO DPA Einstein, I already told you it has a Rawtek Exhaust, Malone Tune, and Deletes!

How much more do you want out of this specimen?
Just take whatever anyone gives you for it if you don't want to pony up to send it to a competent shop.
It's clearly worth way more to you than to anyone else.

The only REAL offer we got was $3000 from a Salvage yard that wanted it for parts, and they kept trying to buy it over and over, they would not leave us alone.

If the engine has been properly serviced throughout its life, these engines could go half a million miles before needing full replacement or rebuilds. The one I have now was bought back by a VW dealership at 24K miles, and then kept at the dealership for the next 7 years and maintained there till I bought it in 2021 at 84K miles. I've still got another year on the dieselgate warranty and I'm keeping a close watch on the maintenence to make sure it's kept up. These things are great. I just had to take a trip from Phoenix to Tacoma WA, and I was able to get over 680 miles to a tankful.

It must be nice to have your's registered in a place that doesn't require emissions testing. I'd like to do the DPF delete, but I live in Maricopa County, where I have to have it inspected each year, so I know it wouldn't pass. I don't have a Malone Tune, but I do have a RaceChip programmer which I run on Economy Level and it's really upped my mileage average.

This truck had absolutely no issues what so ever since 160,000 miles, but we have HAMMERED IT HARD! For the last 100,000 miles it's towed big heavy Trailers, an 8000lb 8.5X18 Enclosed Trailer FULL of tools, and a DUMP Trailer, sometimes as much as 14,000lbs of concrete in the back, we even bent the axles on the trailer.

I don't know of anything else that will tow around a heavy dump trailer, usually 5000lbs to 6500lbs average haul, and still return 15mpg to 16mpg, then when not towing on the highway we DEFINETELY get 30+MPG as high as 32MPG when it had smaller tires, it gets 30MPG with the lift kit and HUGE 33" Tires as long as we're on Cruise Control no faster than 65MPH.

It has massive torque, 490 lb-ft.

I believe it. It's a very niche European Porsche diesel. Not many at all know how to touch them.

Glad you got it fixed though it seems?

 

[dslman]

It's still at the shop waiting for the fuel pump which I assume was ordered. The bill is up to $3300 so far, but will most likely go higher. It's not fixed yet. Even if it starts and runs, the original problem after installing 6 new injectors was that it smoked only when warmed up. No smoke at all when cold, only once it was at normal operating Tempature, then it smoked like crazy. Never did that before installing the new Injectors.

 

[volkswagens-for-life]

Brand new, OEM injectors? Or a crappy chineseium rebuilds? You can't rebuild these by the way...

Were the new injectors coded with VagCom

 

[dslman]

$1200 They came from Germany. Of course they were coded with VCDS, it won't even run without coding correctly.

It ran fantastic after the install and coding, but as it warmed up it started smoking a little, then as it warmed up to normal operating Tempature it smoked like crazy! The next morning, starts up instantly, runs perfectly, NO SMOKE AT ALL, run down the block, as it starts to warm up it starts smoking, by the time it's all the way to normal Operating Tempature it's smoking WHITE SMOKE like the end of the world is coming soon.

 

[volkswagens-for-life]

Lets see what happens after fuel pump replacement. Then I'd look at individual injector balance via vagcom

 

[dslman]

We don't need to bother, it's in the shop, they are going to do whatever is nessesary, including fixing he pesky oil leak since 160,000 miles ago.

If it costs $10,000 to fix, then so be it. If it costs more than that then we will let them keep it, write it off as a loss.

We have another 2014 White Touareg lifted with 32" tires and only 160,000 miles on it so we are good to go. And a 2013 Q7 with 180,000, and 2 Q5 TDI's one with 240,000 the other only has 55,000 miles, but the Q5's can't pull as heavy of trailers as the Touareg and Q7.

I did pull a 5100lb Trailer back from Las Vegas with my Q5 TDI, but that is as heavy as I would ever want to do with that small vehicle again. It was fine, but I did not have Trailer Brakes, it took a long time to stop it.

Why is everyone so focused on injectors?
How much coolant is it eating or has anyone even noticed the colour of the smoke?

 

[dslman]

Yes, I thought it might be slightly leaking head gaskets, I did a compression check it came back with 381 to 385 PSI across the board in all 6 Cylinders, and it never smoked at all B4, this was only a new development After the injectors were changed. However, leading up to this 6 months before the #3 injector bolt broke, we replaced it. (Yes we know New stretch bolts only to be used one time) So then It ran perfectly. 3 months later #4 Injector bolt broke, that was when we pulled all 6 injectors cleaned it up and replaced everything, 6 new Injectors, Copper seals, O-rings, new Stretch bolts. After THAT it started right away ran perfectly, BUT, as it warmed up it started to smoke a little, warmed up more, smoked more, once to Operating Tempature it smoked like crazy. Next Morning, start it up, runs perfectly fine, NO SMOKE AT ALL, until it starts to warm up, then the same thing, smokes a little, until normal Operating Tempature then it smokes like CRAZY A LOT!

The truck was never overheated in it's lifetime.

 

[SaVAGeSoot]

Has the coolant system been pressure tested?

 

[dslman]

Nope!

 

[SaVAGeSoot]

Keep throwing parts at it....
Hint: white smoke isn't from fuel!

I mean, it could be. Raw fuel is white 🫢🫢. You'll know it when you've finally cried for the first time in years because it's so strong.

 

[SaVAGeSoot]

No idea what you're talking about.... I cry "daily" since I read this forum.....

There have been several hints thus far:
This is a 2nd gen motor, and as such, has a more complex thermal management system compared to the CATA for example.....
The owner said white smoke, which points to coolant......
They also said "once it's at operating temp"...... so when the coolant valve opens up at operating temp and allows coolant to flow through the head and EGR cooler, it starts smoking like a locomotive!

I'd say the EGR cooler is cracked.... but it could be something else......
Regardless, coolant should be vanishing, and it should certainly fail a pressure test..... and I'd even suspect that one could smell the burning coolant.....

 

[dslman]

At this point in time, I wish we would have removed the roof racks and those $2500 tires and rims, should have towed it to the shop with some stock ugly and worthless Q7 wheels we have here, because if the bill gets too high and it's still not fixed, we are not even going to pick it up, they can have it! We'll leave it there.

It costs too much money to fix vehicles now days, everything is throw away and buy new now. Unless you can do 100% of the Repairs yourself, to pay a shop to do it costs more than the vehicle is worth. Especially when it's one of these in America, nobody knows anything about them, and when you find someone that does it's so expensive that it's cheaper to Junk it and buy another than it is to try and fix whataver it wrong, despite how good the vehicle looks everywhere else.

And this is nothing compared to a V10 Touareg, those are really crazy expensive to fix anything. Glad we sold our V10 when we did, did not like it compared to the V6 anyway.

At any rate, hopefully we will get another 100,000 miles out of our White one which has 160,000 on it now. By then, maybe we would like to buy a new Canoo Pickup (If they don't go bankrupt) or something similar, we only pull our trailers less than 70 miles in a day so the range is not a problem, and Diesel will probably be up over $7 a gallon (again like it was in March 2022) by that time.

You could be correct. The truck was leaking coolant for more than a year, it never overheated in it's life, but we could never figure out where the coolant was leaking from.

In the end, I think this truck is a goner. Got our use out of it anyways, only paid $15,000 for it Post Dieselgate and it gave us years of hard working service and almost 90,000 miles of hard work. We just hoped it would make it to 500,000 miles, but no such luck.

It's a shame because the whole thing looks new inside, outside, under the hood, it appears cleaner than many used vehicles with only 50,000 miles.

This does not explain why there was never any such smoke at all ever, not until the injectors were replaced, only THEN is when the Warm engine smoke started. It never smoked at all before this.
