:confused: Modern diesel cars, short lived?

You look at all the statistics of diesel car sales and they all show an increase of diesel cars in the car park, but will that continue?
We all know that the cost of diesel is no longer the incentive, neither is the economy of a diesel vehicle better that that of a modern petrol vehicle.
Oh, its has to be that a modern diesel vehicle has a better torque characteristic to that of a petrol engine, but the way I see it the only talking you as diesel owner is going to do, is to the garage when your high pressure common rail system goes wrong.
Will we see common rail engines achieving 100,000 to 200,000 miles on the same injectors, I don’t believe we will.
That shouldn’t be a problem because your old diesel car had its injectors replaced at a cost of £150, no longer my dear fellow diesel owner, try digesting bills from £1000 to £2000, just to replace your common rail injectors.
Symptoms to watch out for are hard starting, uneven tick over, low on power, black smoke and on some vehicles (Ford) the glow plug / heater plug light staying on.
Ok you have recovered from the shock that the injectors are going to cost you that much but I forgot to tell you that the garage has to remove the cylinder head to get the injectors out. On some vehicles the injectors corrode, stick or are just stubborn in coming out that I have heard of cases where the cylinder head had to be removed in order to extract the injectors. A certain vehicle manufacturer even suggests replacing the engine with an exchange engine because is less hassle than trying to remove the injectors.
Now its time to be positive, don’t despair, just have your vehicle correctly diagnosed from the start, be careful of the “local” garage replacing everything under the bonnet using the “elimination method” it will cost a fortune or you will make an enemy of your local mechanic.
Shop around for injectors, compare prices, a good site that will give you an honest opinion is www.uniteddiesel.co.uk regular maintenance, good fuel and a bit of luck helps.
Don’t be to hard on the manufactures; it is still early days with regards to high pressure fuel injection systems, with time they will get it right.

Is this the diesel bashing thread? I haven't heard about any premature failures of modern diesel engines and the current technology has been around for a few years. Also, I was under the impression that VW isn't using common rail but enhanced pump technology.
And yes to me lower fuel cost and better mileage are still the main draws to diesels as long as the emissions are kept in check.

If diesels are so bad.... Then why do Euro's purchase over 55% of their cars as diesels. AND YES THEY GET BETTER MILAGE.... just look at the numbers. But, from an enviro piont of view, there are sill particulate issues even with the best diesel engines.

Huh? No improvement on economy? Are you serious? As compared to what? Please explain further...

My '99 1.8T (petrol) Passat gets no better than 32 MPG, whereas the Passat TDI (2.0l TDI model here in the states) gets 37+ MPG, and I've heard reports of Passat TDI owners breaking 40 MPG. You need to tell us "as compared to what". If you're comparing the Passat TDI with say, an electric hybrid, you might be getting close mileage-wise, but you're not comparing apples with apples if you're looking at a Toyota Prius. Not to mention you have a whole different set of repair issues with the electric technology to deal with which will likely prove to be even more expensive to repair (Still too early to tell on that one). Tell me what car in the Passat class with a petrol engine gets better fuel economy than the TDI?

It's true we're getting ripped off over here on diesel prices (as compared to gasoline, when you factor in cost to refine each), but who isn't? Thank the profit-hungry oil companies for that mess. If you maintain your vehicle (follow the recomended service guidelines), and run a good quality fuel, you should have no problems at LEAST matching any petrol motor for longevity. And if you run Biodiesel, you'll see an improvement in emissions and fuel system "cleanliness".

Your post makes it sound like you've got a bone to pick with someone. Don't blame the diesel technology and/or lack of maintenance on your part if you're getting gouged on repairs by your dealer - go find another repair facility or learn to do it yourself and same a ton of money.

I don't mean to sound like a jerk, but I don't understand your reasoning. Looking forward to getting more info from you.

Why is diesel fuel so high now? It runs from right below regular to almost premium gas pricing, depending on what day it is. I remember when diesel fuel ran 10-30 cents less than regular. Is it because so much refining capacity is taken up with gasoline?

Well I have a 2000 V6 Syncro Passat and Ive just had it converted to LPG. Main reason being fedup with putting £45 of fuel in it every week. Now its like £20 every week and to be honest I cant tell the difference in performance at all. if anything it feels more like it has more torque low down.. I would recommend to people out there to look into having this done. Mind you the conversion cost £2000 and took 9 days to do but I should get the money back in 2 years hopfully..
Every time I fill up now it puts a smile on my face LOL :)

Couldn't agree with you more dlai,
If he knew what he was talking about he would know that 95% VW/Audi vehicles have not and do not run common rail injection systems. Why talk of Ford and injectors that require engine strip, this does not apply to us either.
TDI's are still leading in fuel economy and torque, admittantly VW's latest Supercharged AND Turbocharged 1.4 petrol pumping out 170bhp, bags of torque and achieving 40 (imperial) MPG is hot on our heels, but when our stupid arse government finally start backing Biodiesel, we will be laughing! It is the only short term solution until fuel cells, hydrogen and electric are viable and cost effective!
