Was this to me ? I just posted what has been repeatedly said about it. I also clarified that by saying I didn't know why. I want the CRD.

Re: Diesel People - Enlighten Me? (2014)

Some speculate that the fuel pump issues on US VWs may be related to our ULSD fuel here being not quite as good as in Europe and elsewhere. Supposedly lower lubricity which kills the pump.

That being said, no fuel pump issues with ours or the 5 other people we personally know. I think forums and the internet in general greatly magnifies a low percentage issue.

We do save our fuel receipts however, just in case...

Re: Diesel People - Enlighten Me? (2014)

Are we sure it's diesel at all related to HPFPs? BMW has this issue in their gas engines since 2008. They have a special high mileage warranty on them because of it (or the gossip on the internet)...

I reckon "high pressure" may be the issue, not what is high pressured.

Doesn't 8 injections per rev mean 8 times the wear? I'm not sure the "diesels last forever" statement can be used for modern diesels that have been out for 2 years. Direct injection in general is great on paper... I just don't know.

I wish engine life mattered anymore, but frankly, I don't think cars can be maintained anymore past about 12 years. It just isn't cost effective. What's my point? Not sure. Just thinking about cars and life and stuff...

Re: Diesel People - Enlighten Me? (2014)

Most problems occurring in the HPFPs are related to Biodiesel, since it dissolves some of the gaskets and O-rings. However, no issue in germany.

8 Injections mean "pulsed" injections, so its basically one injection elecronically divided in multiple fractions.

Diesels are no more "forever", since nowadays you expect the same or higher performance than in gas engines, means more stress on all components.

The "forever" engines had a pretty low performance combined with a large displacement and distributor pump controlled injection. pretty slow, too. However its not uncommon for modern engines to last much more than 200k miles, proper maintanance provided.

Happy Day

Re: Diesel People - Enlighten Me? (2014)

So far, all we have had down under regarding the fuel supply is a fuel rail sensor failure, see O No, our CRD is broken! .

Re: Diesel People - Enlighten Me? (2014)

After reviewing many of the posts here, it is clear that quite a few of you are groping in the dark in regards to the CRD.
Longevity? Forget it. These are not old Jimmy two-strokes. As many have posted or speculated, high pressure fuel delivery is far from being mastered, especially on the light duty engines. Tier 4 and diesel really do not belong in the same sentence. I see it every day in the heavy construction equipment end.
Back in '07, I had to have the MB CDI, and that is the reason I bought it. On paper, it really makes no sense when you do the math. The payoff is so far down the road, it is really difficult to justify past the "gotta have it" want. I have read some issues with the CDI now that they are several years old and have mileage on them.
Same is true with the '08 6.4 Power Stroke I had. Known for fuel rail issues that require the cab to be removed to change.
I think it is great that Jeep is offering this option, but, between the premium and the lack of true technical support at the local dealer level, it is a gamble I would probably pass on.

Had my CRD for just over five weeks now and found out the costly way just what a treat it is. Pushed the right foot down a little hard going through an intersection (green light) and got pinged by the speed/red light camera

Older diesels may have had problems ... my old man had to get all the rubber seals in the fuel system of his old Toyota Troop Carrier (1HZ straight six - no turbo) changed a couple of years ago. His diesel mechanic put it down to the change in the diesel causing the type of rubber that was previously used drying out too much. He had a couple of minor fuel leaks and lost some power. Since having the replacement the engine is still going strong, currently at 383,000km. However the old man keeps the engine well maintained, oil and filter change every 10,000 km, fuel filter the same (offset from oil by 5,000km)

At the end of the day if you look after it you'll be fine. Abuse it and expect to pay.

Just for reference.

Re: Diesel People - Enlighten Me? (2014)

Hello to all Members, I am on the fence about the CRD or a V6 I would like the CRD for mileage, do not tow or really have any long trips. But what I would like to know from all members that will be getting the CRD what diesel brand would you consider and think if one is better than the other, I had a VW diesel traded it in since all the problems with the diesel here. I believe the Jeep CRD has same fuel pump as VW, any info would be appreciated, I just may go back to CRD dealing with a salesman who calls me whenever he finds info out. Thanks to all

Re: Diesel People - Enlighten Me? (2014)

wow what a thread - I haven't read it all I'll have to go back ... later ....
you should know I own 2 diesels; an 09 VW TDI and an 07 WK CRD. I am biased - I think each one is best in class.

I can speak from experience about the high pressure fuel pump. The VW's pump blew up, and it was repaired under warranty. My fuel was tested and found to contain 5% biodiesel, which is what is sold at the pump in my town. The new HPFP is working better than the old one, and I'm confident that the defect(s) that existed in the early model have been corrected. This same pump was used in Audi and BMW, and they had a similar failure rate. That kind of thing happens with new designs, and hopefully one's warranty will cover it, as mine did.

In my CRD, the HPFP is running at a lower pressure (about 25K PSI vs 29 PSI in the VW), and there haven't been any problems. There have been other issues with things like glow-plugs, & intake assemblies, & swirl motors, & other stuff, just like any vehicle will have.

Which brings me to the real point, as voiced by others in this forum - you need to check out your service options before you buy.

A lot Chrysler dealers never even knew my MB 3L diesel was a factory option, but I'm fortunate that my local dealer is not one of them. (When I tell them my engine is burning oil, they give me thumbs up)

It remains to be seen how Chrysler will support the VM Motori engine in the US 'cause overall, they blew it with the Benz diesel.

Hopefully your dealer will NOT quote you on the cost of replacement spark plugs!

I might go to my VW dealer for Oil Changes on my "VM Motori" diesel. At least I know they have the correct oil...

oh I'm not so sure about that either....go check out the TDI forum for info on that topic ;-}

the US really is kinda late to the table on diesel - I think that's what this thread is really about but some's asking the questions and that's a start!

Do they work in cold weather? Check out all the Canadians driving the WK CRD!

Are they economical? Listen to the folks who pay nearly tice what we do for pump fuel!

Do they have power and performance? check out the Gale Banks version oh man if only I could....
