New 2.0 TFSI VW out of oil after 4k miles

Diesel's are inherently less reliable due to more potential failure modes.

Exactly - and its this that makes them unreliable not the fact its a diesel.

My car has direct injection and two turbos and is thus just as inherently unreliable as a modern diesel.

However most petrol engines have neither...
 
I may only have 4k miles between services on the bike, but they are notorious for using oil.... mine hasn't moved on the sight glass once :) (Dipsticks are horrific on bikes)
 
I got my Golf new and didn't check the oil before the first service at 18k. Seemed ok :D

Not something I would be boasting about. Seems to me you need to be signing up to a white goods forum, those are the items that most people only pay attention to when they are broken.
 
ROFL you made that up...

He didn't make it up at all - it's true. I suggest you probably didnt quite understand what he said.

A diesel has more ancilliary components than a petrol (On average, ignoring specific high end petrols or low end diesels). If something is not fitted to a car it is not at risk of failing.

A standard petrol engined car is not normally fitted with direct high pressure injection systems, turbochargers, regenerating particulate filters, therefore they cannot go wrong.

When you add the same things to a petrol engine - you get the same result - additional risk of unreliability. Case in point, BMW's N53 and N54 engines...
 
Most diesels are more reliable than petrol engines as they are built like tanks.

Its the ancillaries that seem to bugger up, like DMF's etc.

If you look at the most agricultural diesels out there, its common for them to do well over 200K on regular oil changes and basic looking after.

You cannot say the same for the majority of petrol based cars, as the engines are simply not engineered for the high pressures of the diesels.

Quite simple really. It all goes wrong when the manufactures try to get clever, however Peugot and some of the German diesels are fantastic and would outlast the car!

But with modern emissions standards manufacturers have no choice but to 'get clever'.

An old school bulletproof diesel engine would not be legal to be sold in a new car today - it would fall far short of the regulations. The only diesel engines which do pass the regulations are ones that are loaded with complex kit to enable them to pass...

Perhaps you should explain to me how an engine which is not fitted with a turbocharger can experience turbocharger failure? :confused:

You said nothing about turbo charger failure.

You made a statement above that suggested petrol engines cannot go wrong just because they dont have some of the ancillaries a diesel engine has.

Quite clearly, this statement is pure horse manure.

Quite clearly you can't read.
 
I made a statement that as a petrol engine does not have these additional ancilliaries, they cannot fail - because they are not fitted in the first place.

Nobody would ever imply a petrol engine can never fail, that is the most ridiculous thing I've ever heard.

Negative. I can read perfectly well thank you.

Its just poorly worded and constructed statements are there to be corrected and/or questioned.

Im a big fan of the M47 engine, one of the most reliable around. Especially the detuned one fitted to the ZT range.

Different turbo, no stupid inlet manifold electric valves... just like a tractor!

Had a few cars with varients of this engine, and generally a good experience all round. The Cummins engines are bulletproof also.

It is no longer high end petrols that are complicated my mum's petrol Fabia has a turbo, high pressure fuel pump/injectors, intake swirl flaps and a DMF all for 85bhp. It won't be long until all petrol models are downsized and turbocharged bringing the same failure points bar a DPF as a diesel.

Only a complete idiot would infer that someone meant it is impossible for all petrol engines to fail from that post.

What? No it's not! There are numerous issues with the M47, its quite common to suffer turbocharger failure and who could ignore the swirl flap debacle?

Especially the detuned one fitted to the ZT range.

So really then you mean one specific variant, not the M47 as a whole..
