Why would you think a diesel is more unreliable than a petrol??
If anything they would be more reliable as they dont have the same electronic ignition system as a petrol.
I suggest you look in to how modern diesels work. They've as much, if not more electronics than a petrol.If anything they would be more reliable as they dont have the same electronic ignition system as a petrol.
Typical clueless response.

Clutch was starting to rattle = new clutch and Dual mass flywheel. Average quote based on 8 garages - £1000
Wife has 2.0 TDCi Focus.The DMF failed at 18,000 miles.
£720 to replace.
DMF failures are commonplace on Ford TDCis.
Won't be buying another one, thanks.
Same reason I won't be buying another one either. Lovely cars - just ludicrously designed around parts that cost hours in labour to get to, that are prone to failure.
my mum had endless trouble with a 1.4 TDCi ford, pump went 3 times (luckily, twice in warranty and they repaired it the last time FOC as the problem was obviously pre-existing) and there were various gubbins changed relating to the issue. They never solved it, she mentioned trading it in, they offered her a discount circa £500 off the replacement motor to ensure the story stayed stum.
Driving the missus 1.4 petrol fiesta sensibly i get in the region of 45mpg on the motorway so i'd strongly suggest a small light petrol car.

Just to put that price into context, the same chap also replaced the cambelts, tensioners etc on a Ferrari 328 that I used to own.
I supplied the parts and he charged me £165 for the labour.
Who said that Fords were cheap to run?
I'll stick up for the diseasels:
Aud A4 1.9 TDi - I put 90k miles on it, from 40k to 130k. Went like clockwork, but then I always had it serviced with genuine parts and top quality oil.
Ford Mondeo 2.0 TDCi - couple of warranty issues (it's a Ford) but after that, same again. Mrs Badger put loads of hours on (if not miles as doing school run etc) - no problems.
So as one of the previous posters mentioned, looking after them helps.

She once had the nerve to tell me to stop 'revving' my car because 'I'll break it' - 6000rpm in a correctly warmed up petrol engine apparently causes damage that revving the tits off a dry turbo in a diesel doesn't because 'diesels are real strong'.
This wasn't your knackered Zafira that eats an gallon of oil every 1000 miles and sounds like a skeleton w
king in a biscuit tin is it? 
I think she was right!

I've been waiting for the Zafira to die. I found out 6 months into ownership that it had suffered a snapped cambelt at 40,000 miles. It's never ran properly (no power above 4000rpm) but I got a very good deal on it (px'd a more valuable car for it) and intended to run it into the ground, which I've done.
Basically all the German manufacturers have been having problems with Diesels. As I believe PSA have with their diesels. Particularly their DPfs. Strangely all the faults are the same, regardless of manuf.
Turbos, Dual mass flywheels (diesels are more buzzy than petrol of course), Injectors, Diesel Particulate filters and assoc systems and fuel pumps being the big 5.
If you must have a diesel. Get the old (tractor) pump systems. Simplier so less chance of it going wrong. Not as good on fuel mind. And obviously "obselete" to manufcturers desperately trying to meet emmissions targets.
I would NEVER touch a modern TDi. Consider the cost issue. Petrol injector for Golf is £150ish. Diesel injector is £450ish. And as above. Due to customers not driving their cars in the "correct fashion" DPfs are really likely to get sooted up fast! BTW "correct fashion" seems to have been invented by someone with no concept of town driving! Only people who do 150mile commutes regularly.

I wouldn't touch a new diesel with a DPF, but otherwise I would have no issues at all.
That being said I had a MK6 Golf 2.0TDi CR (140) as a courtesy car and it was amazing, diesel technology has moved on so much from my 8 year old PD diesel and it was a joy to drive, so in that sense I would buy a car that's a joy to drive over a car that's only redeeming factor is the reliablity.

Like "most" modern diesles that 2.0 TDi has a DPF. If you thought the G-Lader was VW's finest time bomb, it's nothing on DPFs!That being said I had a MK6 Golf 2.0TDi CR (140) as a courtesy car and it was amazing, diesel technology has moved on so much from my 8 year old PD diesel and it was a joy to drive, so in that sense I would buy a car that's a joy to drive over a car that's only redeeming factor is the reliablity.

Isn't the rule with a DPF just to make sure that you allow the exhaust gas to become hot allowing the particles that have collected in the filter to be burned up or are there other issues?
That's the only issue I've heard of. If it doesn't get hot enough to burn the residue then it can clog and (on Alfas, anyway) the engine goes into a limp-home mode and sometimes stays there until you take it to the dealer for them to do a manual re-gen. I think different systems work in different ways, so that might not be true for all of them.I'm sure I read that VW were not recommending DPF-equipped cars if you mostly did town driving, which seems to miss the point by quite a long way.
Our old V70 D5 was excellent for 4 years, but when things started going it was a nightmare. The problem is that independent specialists that understand modern turbo-diseasal engines are few and far between, so you're forced to stick to the main stealers really who pummel you on the labour charges .
