I've had my diesel for over 3 years and 32k.
I've had no issues from the engine. I blanked the EGR though as they are a weak area.

Regular servicing and good quality oil keeps mine fine, although its going into the garage on Thursday to get a few things checked/repaired and the cars going to have a chat with a diagnostic to see what's causing a amber engine light to come on going up steep hills. So that may be my first issue.

Are you sure?

Diesels tend to cost more to be used but depreciate less due to the much larger public demand for diesel cars.

Of course I guess that depends on what car you have.

but arent modern petrol cars also using turbos to reduce emissions, so they will be the same issues as diesel?

yup... but I was shot down for bringing this up earlier as the difference in fuel economy "will make up for it" rolleyes

It's not just turbo issues though. Also DMFs and DPFs. High power diesels are also more likely to have dual turbos so more chance of going wrong (however VW are putting multiple chargers on their TSi engines).

On top of this, petrol engines are not compression ignition, so kill the power and they can't 'run away'.

Its recon'ed to be around effectively around 2 MPG difference due to the cost of diesel being more, so factor that in but then include the increased road fund license and then you get to the costs from there.
A couple of years back my wife had a 2001 1.8 Focus Zetec Hatch. When I used it on my daily commute it got 32 mpg. About a year back I bought a 2003 1.8 TDCI Focus estate. It gets on average 42 mpg on my commute.

So I get 10 mpg more, 30% better than the roughly equivalent petrol car.

I do about 12k a year so at 135.9 p for petrol that would work out as £2319
Same but in the diesel at 143.9p that works out as £1871

So that's an annual saving of £448 or a 19% saving over the petrol.

The increased cost of diesel means the effectively the TDCI is getting the equivalent of about 40 mpg. So that's still an 8mpg difference, not 2 mpg.

It's also a 3.8 ppm saving not 1.5 as someone else said.

How much more did the Diesel Focus cost than an equivalent (age, form factor, options) petrol engined model?

I'm currently driving my Dad's 2008 TDCI Focus, while my Bora 1.9TDi is in for some work. I can't get more than 42mpg out of it in normal driving (max 45 if I really really try) - whereas my 2000 W reg Bora will do 48mpg absolute minimum, 55mpg easy on a run.

Such a shame, that diesel engine in the Focus is one of the worst engines I've ever experienced, but the chassis and drive of the Focus is superb.

And how much will it be worth when moved on? (assuming of course that we don't all buy new cars and keep them until scrap)

Having just changed a Mondeo DMF, I think I would pass on a fresh out of warranty turbo diesel. I would much rather buy an old W124 for a bag and spend another refreshing it.

That's a difficult question to answer.

When i was looking I viewed and test drove both petrol and diesel models but as I was after an estate and had a limited budget I never really looked at two equivalent spec/age/milage cars.

I reckon I probably paid an extra £500 for the diesel model over an equivalent petrol. I never set out to buy a diesel specifically, I bought on condition/history and the fact that the petrol engines felt lethargic in comparison to the diesel. Had the 1.6 petrol zetec I'd seen before been better I may well have bought it there and then and never even looked at the TDCi though.

When you have a budget of £3.5k you can't get too fussy about which model you go for.

I plan to keep it for another three years and as long as I look after it I expect to get at least some of my extra £500 outlay back.

A Diesel estate Focus will always be an easyish car to sell on.

I know what you mean.

I keep looking at old E39s and E36s.

Its interesting how public perception has lagged the advantages of diesel. Back in the late 90s and early 00s diesels were getting good for the first time, like the 110hp VAG TDI and XUD HDI units, still didn't sell that well in comparison, even when the price differential with petrol was almost non-existent.

Petrol for fun, diesel for when you have to drive.

My £500 bangernomic HDI Pug is brilliant for the motorway or for popping to the shops. Reliable technology, cheap to run, cheap to insure, and just failed its MOT. rolleyes The bike is for fun.

It does look like ford have some issues with their diesel engines , shame really.

My tdi passat is on 100k , at least 40k has been done short city driving and the only thing went wrong with the car is a lift pump and a noise while driving over uneven surfaces . And I know both faults can be traced to my euro trips , catching air at 80mph is not cool .

That came across all wrong!

My old car was a 2005 and my new car is a 58 plate so the golf still has some value to come off in depreciation compared to the A3 it replaced. But comparing 2 similar cars, one petrol one diesel, yes you'd expect the diesel to depreciate less.

I do love PH's attitude towards diesel, just hilarious.

I recently changed from a petrol to a diesel and rough spreadsheet calcs say I'm saying over £1500 a year in fuel, £200 a year on insurance, £215 a year on tax, servicing will be roughly £10 cheaper and the interval is the same. Only difference is that the diesel will depreciate more but I have a car 3 1/2 years newer so I'm happy to see some of the £2k I'm saving a year go on depreciation.

Reliability? Well my petrol went wrong all the time, and my diesel is generally regarded as being absolutely bullet proof. It has a DPF but the car oak most exclusively sees dual carriageways and motorways so no need to worry about it clogging up.


And I "only" do 13-14000 miles a year.
What did you change from to gain £1,500 per year? When I sold my 29mpg E46 325i for a 45mpg Passat diesel I worked out that my fuel savings were around £750-£800 a year over a very similar mileage.
Traded in an Audi A3 3.2 which was doing between 25-30 mpg, long term average was 28 mpg, for a golf bluemotion, getting a long term average of 56 mpg. The audi 'had' to be run on super unleaded (and you could kiss goodbye to 3-4 mpg if you didn't) so the cost per litre of fuel is similar to now having a diesel (say £1.40 per litre vs £1.45 per litre), fag packet maths says in the region of £1500 saving.
