"You can't tell it's a diesel"

Must be an VX thing. The CDTi must be good in the 'quite' stakes? Seems buy this thread BMW diesels are quite noisy? Just an obversation no way am I saying its a fact!

All it really tells us is that there are differing levels of denial in the thread. The BMW 4 cylinder engines are amongst the very best, the fact his Vauxhall is apparently silent and smooth is a product of his imagination and not a negative reflection on the BMW 4 pots.

:rolleyes:I dont have any issues with BMW diesel engines at all and would agree that they are one of the best 4 pot diesels currently available. The o/p stated

"It's obvious from the rattle and the vibration when it's started. Once on the move it's obvious from the rattle under acceleration. When not accelerating it's obvious from the flat drone from the motor."

I was just stating that I do not get that in my crappy GM Diesel but then again as you clearly state I must just be making it up.....

Ho hum...

This is simply not true - modern diesel engines have the following failure prone items not fitted to petrol engines*:

a) Direct Injection
b) Turbochargers
c) Diesel Particulate Filters

They also have disprooprtionately high failure rates on dual mass flywheels as a result of the higher flywheel torque outputs.


* Some petrol engine cars these days are now supplied with things like direct injection. Somewhat unsuprisingly they are also proving less reliable than petrol engines without this technology.



I can't think of a way to put this without upsetting you, but your diesel Vectra is not 'almost silent' at all. I have driven numerous diesel engined cars from various manufacturers and the only one that came close to being 'almost silent' was the very latest F10 530d. Even that STILL had the diesel thrum at idle.

Sorry, but your Vectra isn't some sort of rare exception to the rule. If it's a 1.9 CTDI 150 then I can personally attest to the fact it isn't virtually silent.




Wait so its an older Vectra diesel? And you still think it's silent, quiet, is no less refined than a petrol engine and offers flawless reliability? Just lol.

I can't be bothered replying to all that. I must bow down to your far supperior driving experience and your level of knowledge on such issues. Owning 30 odd cars and being a qualified mechanic I would not dream of trying to contradict anything you have posted...

Have fun....

Which is the more likely scenario?

a) A BMW 730d - a top end luxury car containing one of the very best 6 cylinder diesel engines - is noiser and less refined than a cheap Vectra diesel

b) You simply don't notice or don't care to admit the traits exhibited by said Vectra diesel.

A qualified Mechanic claiming that modern turbodiesels have no reliability issues?

So all the hassle people have with injectors, dual mass flywheels, turbos and particulate filters are all... made up?

No you are posting miss representation's .. I stated they have no more reliabilty issues than the equivelent petrol models.

Anyway I couldn't care less I have some nice real Ale that needs drinking..

I,m out....

come off it

We all know what issues the CDTI 150 engine in the vectra has. The length of problems on vectra-c is as long as your arm. Don't make me get the list of common issues out ...

In order to do so you must be stating that the turbos, direct injection systems, DPF's etc NEVER fail - as the equivilent petrol models are not normally fitted with these (And where they are - hello BMW 330i with direct injection, the reliability issues appear here as well).

He's had 30 cars and is a mechanic, he can't possibly be mistaken. Also, his Vectra diesel is more refined and more quiet than a 730d.

Sadly all he's doing is demonstrating exactly the point that Rilot was making in the first place..

And the list for the petrol vectra models is just as long. I don't claim vauxhalls to be great or by any means say that the diesel's are without issues but common fault lists for both the petrol and diesel vectra's are about the same.

I,m not wanting an argument we all have diffrerent opinions and this will go on all night..

ah so we're agreed the petrol build quality is as bad as the diesels then ?

Wonderfull, maybe now you'll stop preaching that they are very reliable.

Oh .. wait a minute ...

When have I ever saind that. I,m quite often wrong and have no problem admitting it does not bother me in the slightest.

I have not said that my Vectra Diesel is by any means more refined and quiter than a 730d. I have stated that I do not get what the O/P has stated about his Diesel..

You really do like to bend words to fit what you want.. Please if you want to quote me at least quote what I have put..

How many £1k failure points are there on a 2.0 16v Vectra petrol engine?

Infact is there anything common which goes on them that costs that much?

We all know that for the diesel there is the DPF, DMF, injectors, turbo..

If you claim not to have with your car what the OP gets with his, then you are claiming your car is more refined than a 730d. It's that simple. There is no other way to take it - he owns a 730d and states that about it, you claim this doesnt happen with your Vectra.
