I do love the brown color! I choose a boring darker silver like everything else on the road. Later I saw the brown and though I should have went with the brown.

So with cheat mode a manual TDI is 20% more efficient than a w124 manual diesel.

Yes, however the 124 isn't making 165hp and 295 ftlbs of torque.

I'll pay $13K for it, and it seems like a good deal but I'd love any advice folks have!

For those that don't know, the dieselgate warranty actually covers a lot more than just emissions equipment - including the HPFP, turbo charger, fuel injectors, etc.

Where are you finding these cars? My search has been fruitless.

The 1st 100,000 at least should be trouble free. One of the questions asked in the buyback questionnaire is "does the car drive on its own" or something similar. I guess that means that you can't have it towed in & still claim buyback.

Of the three I tested drove, the first was in the roughest shape - it had a uhaul hitch installed and the transmission (a manual) shifted a little oddly. It was very peppy and fun but it had seen some tough miles. The second was a DSG with a sunroof but I never want the liability of a sunroof - I'll own a convertible before a sunroof. This was the third of three, it was an incredibly clean six speed and just minty fresh. The color didn't hurt either. Between this and the 240D they'll be like reeses pieces.

In terms of where they are, use car guru and view all dealerships - look for 2013-15 VW models and filter by fuel to diesel. There are going to be a lot of potentially very nice vehicles all over the place for good discounts and the warranty is stout.

Any member not too far south of the Canadian border. Should remember the American dollar is worth about 30 percent more in Canada.

There is a 2015 jetta tdi sitting at the local used car lot. Asking is less than ten K US dollars. Plus I do not think there are any restrictions on importing one back into America. They are all built in Mexico.

This one is black on black I observed but did not really examine the car. So I have no ideal of the accumulated milage. Or any other details. Other than it was not the bottom end model as I remember it had a sunroof.

I expect a semi flood of them released up here in the not too distant future. The logic being they depreciate further with time. So Volkswagon will want them out there as quick as reasonably possible.

American car dealers are buying up just about every used Toyota in Canadian auto auctions and taking them back into the states. Perhaps good half ton trucks as well.

Another suspicion is there may be far more Volkswagon buybacks available eventually than the market will easily absorb. This could impact the prices further. Hard to guess this one with any accuracy though.

Not true,, my wife can attest to that. Just a $600 fee to clean the entire system and refill with diesel. Car went another 70k after that and was still running fine.

My '09 Jetta TDI 6M Had its fuel pump self destruct (warranty covered it) - they sent a sample to get analyzed before they would warranty the repair. Two/three months ago, I had them to the emissions modification. It seems a little louder now, and not quite as much oomph, nor is the mpg what it used to be. However, the $ they gave me, plus the warranty was extended enough to get me past 150k miles, and that warranty covers A LOT. It is still fun to drive, but not quite as much fun as it used to be.

t walgamuth · #39 07-08-2018, 08:20 AM

Mine has enough power I would not miss a small reduction. I often spin the tires taking off if in a hurry such as getting across a busy street.

Do you know if use of diesel additives voids warranty? I use biobor and diesel kleen in my benz and would like to use both on the wagon. Any idea what they were looking for when they ran their tests? Maybe just checking gasoline wasn't used?

No ideal but perhaps the percentage of bio diesel in the mix? Those high pressure pumps are also a high failure item.

If after warranty many thousands of dollars usually. Best replaced at 100k as a preventative issue. Only around a five hundred dollar part.

Other wise if they shred metal internally it means new injectors etc as well. They are expected to fail at some point. I do not understand the checking of the fuel. Other than for their own research.

They will not warranty the system if they find gas in it is proven. So your guess here is probably right. This also applies to earlier models.

t walgamuth · #42 07-08-2018, 03:26 PM

You're saying replace the injection pump at 100K?

barry12345 · #43 07-09-2018, 07:16 AM

Does not have an injection pump as such starting in 2008 I suspect. Instead a very high pressure pump feeding a common rail system. Probably the pump is in in the forty thousand psi pressure range.

Yes when you get up around that 100K thinking about a replacement is probably wise. Assuming you are not near that milage yet.

Simply when this pump shreds metal it gets really expensive to repair. I have no ideal if increasing the lubrication of the fuel would help or not. This issue can be followed on a Volkswagon sites for better indications of the overall situation.

My first thought when this situation was reported. Could they not have put a very fine screened filter after the pump to stop the shredded metal reaching the injectors? Or perhaps in a situation where the car had run out of fuel. The high initial differential pressure across it would destroy the filter when re establishing flow?

I also thought a very strong magnet located on the feed line from the pump somewhere might capture the small pieces of shredded metal . If this would work. It very well might. Volkswagon should have done it though. For the low obvious cost.

If there is a physical place to install a strong magnet on the feed line to the common rail system I think it would do no harm to install one. It may or may not save the injectors if the pump shreds.

On the other hand Volkswagon have missed things in the past. Or not suggested a potential solution. .

I suspect the velocity of the fuel in that line is low enough. That a strong magnet might work. From the repair bills mentioned those injectors must be very expensive when that pump fails in the way it does. A new pump at even five hundred is probably very cheap in comparison. To having a failure. This is possibly the only serious failure issue with the more current diesel engines of theirs.

How many fail? Enough to be a concern I suspect. A guy could phone a dealer and ask what the cost is to repair a car that the high pressure fuel pump has shredded in. I have heard it is in the thousands but without probing volkswagon sites I just do not know.

No a magnet on that line will not increase your fuel milage. At the same time it will not diminish it. It just might save the injectors though as the pump will be high pressure at low volume. Indicating the flow rate of the fuel is very low in that feed line. Giving the magnet a chance.

What really burns my tail feathers. If Volkswagon knows how to stop this problem. They would have to admit it is a problem. They are a company that at least since after the air cooled days. Tends to let the problem exist rather than risk any liability in declaring it as one.

I went through it when their older turbos almost never failed. On the early tdi engines the variable new turbo was a failure epidemic almost. They never stated it was a problem at that time either. Around a fifteen hundred dollar issue that caught a lot of owners. Ours failed very early under the warranty on the 2000 model. . Far too many just made it past the warranty.

Our old 2006 with the cam eating problem is yet another. A local really expert mechanic found that their factory recommended oil change frequency was too long. Again rather than suggest customers shorten it up. Volkswagon said nothing. They almost had to know.

As I have mentioned many times. This company builds an interesting product. At the same time their general corporate attitude towards customers leaves a lot to be desired. Reading any Volkwagon repair site will give a person a pretty sound indication of this.

t walgamuth · #44 07-09-2018, 07:25 AM

I'll take a look. Mine is over 100K now.

barry12345 · #45 07-09-2018, 11:44 AM

Since I do not own one I have not done any in depth research. There should be good write ups on the issue on the Volkswagon forum threads.

The magnet ideal is mine. It may or may not work. I just visualize it as better than nothing.

As you are aware there are some brutally powerful magnets out there today. So strong they will even self adhere to the fuel feed line. With enough force of attraction you physically will almost have to struggle to pull it off.

I do not know the indicators of the pump is shredding. It may be the metal shavings get into the injectors. So the engine does not run properly. Rather than the high pressure pump actually stopping to pump. Possibly the output pressure declines slowly as well.

As I mentioned. I have just heard in various places these pumps fail. With what regularity and percentagewise I do not know. Enough to call it a chronic problem I also do not know. Depending on the type of pump design they are it could even be damage from water in the fuel over time.

Come to think of it I have not even investigated the old 2006 for a water separator in that system. Years ago their earlier diesels had a nice large one near the rear axle.

I perhaps should get a little more up to speed on what we own probably. Converted to miles it shows about 115K and is running very well so far.

I will change the oil about every 3 to 4K miles. Because of the cam issue on this particular year of engine. It also has a more frequent timing belt change at every 80K miles.

Probably as the timing belt also drives the injector pressure to 26K psi in each injector increasing the load the cam sees. .Technically this 2006 engine does not have an actual injection pump either. The cam drives each injector to 26K psi and then they are electronically fired. My fuel delivery pump in the tank is around 6psi. No engine driven high pressure pump other than each injector. A self pressurizing common rail system?
