....apparently'

A few people have spouted similar comments stating that there is so much technology packed in to control emissions , etc.

Just wondering if this is fact that modern diesels tend to be a bit of a wallet opener later in their life and best avoided.

Anyone got any experiences or opinions?

There will be a stack of horror stories along shortly.

I've just got a brand new one of these quite pokey, low emissions diesels. I'll be giving it back and getting another brand new one in two years. No way I want to run one out of warranty. Otherwise I'd buy a petrol.

Yes I agree with this sentiment to some extent, maybe not on new cars but certainly on 3 to 5 year old cars. When you add up the cost of replacement injectors, turbo, intercooler and oil pump failures, emission control problems with egrs/dpfs/swirl flaps etc, worn out dual mass flywheels and clutches plus extra strain on suspension components due to increased torque then yes they are a complete money pit.

I don't get the obsession with modern oil burners, buy petrol cars, they are more reliable, cheaper to run and for the same price you get a newer one with fewer miles, and the best bit, they sound better!

I guess this is all about the exhaust gas recycling systems and diesel particle filters. Had several cars with this on and It's no problem. As long as The car is used regularly for journeys of reasonable distance the system can clean itself. Roll round town once or twice a day at 1200rpm and It will hit the wallet replacing it all when it clogs up.

If all that happened in years 3 to 5 I'd be looking for a manufacturers good will gesture of a generous amount.

I currently own my first (and last) diesel car.
Any saving in apparently fuel economy over the equivalent petrol model is wiped out with extra servicing costs, buying fuel system cleaner every 3 months ( £80 a year) , and paying for the EGR valve to be cleaned twice a year, charged at an hours labour each time (£160 a year).

Now at 65000 miles, the EGR needs to be replaced, over £500 all in. So these detailed costs would have bought me over 120 gallons of fuel, or circa 4000 miles worth as a worst case calculation. Where is the saving?

I think if you spend most time on the motorway and avoid short journeys, diesel is ideal. Anything less than that, stick with petrol.

The worry seems to be that the current vehicles could be susceptible to poor treatment by the previous owner, then again the potential is that any major common issues will be fixable with pattern parts that will bring the scary bills down, the unlucky ones will be the owners in the first tranch who show what pattern parts are required. I can remember paying hundreds of pounds for a replacement catalytic converter for an old Astra, a few years on and they are a hundred at the most.

Why use so much diesel additive? If you give the car a hard drive on a regular basis you shouldn't be cleaning the egr and picking up bills like that? Also I've been told to avoid super market diesel but that's A different subject...

As has been said, Diesel is fine if you're doing loads of motorway miles, but if you're doing around 10k PA then petrol is a better bet.

I'll be interested to see if I have any issues with my 520dull as I'm up to 50k in 16 months so it will probably do about 120k before I change.

The other issue with Diesels is the cost of replacing the fuel pump and the injectors. I was at Feathers last year and chatting to the service staff whilst they did some work on my car and the cost of replacing the injectors on some modern diesels if they can't be reconned was nearly 1k per injector. Obviously prices will come down as the tech ages, but still, I wouldn't want to be at the front end of that wave.

Err, you don't like the sound of a petrol engine? You on the right website?

Isn't the solution to DPF&EGR failures just to remove the fking things and remap the car?

That just leaves dual mass flywheels and turbo failure to rape your wallet.

I've had a Mini Cooper Diesel for just over 3 years now. I get about 64 mpg which is about 20 mpg better than my previous petrol Cooper. I do about 28,000 miles a year and I've noticed that the heavier engine increases front tyre wear, but I do like the car and would certainly get another diesel if I'm still doing the same mileage when I come to replace the car.

EEk!

I fear for my poor car - and wallet. I bought an A6 2.7 tdi in March on about 60k miles, my first diesel too, and I have to say it's a fantastic drive, a fast, comfortable and economic cruiser and load lugger. It looks like its probably due a service around Christmas time, but I've had no issues at all in around 8000 miles of driving.

It gets a short sharp drive to work most days and a regular 400mile round trip to Yorkshire a couple of times a month. Now I'm going to get paranoid, a sensor is going to go pop or a swirl flap will fall into an intake and lunch the engine when I next drive it!

Are you guys talking about the more recent 10/11/12 reg diesels like the new efficient dynamics BMW 2.0 which has incredible output (180bhp?) and amazing economy? Or is it all "modern" diesels from the common rail/high pressure period?

Should I sell up and run away while I have a chance?
