This argument discussion is easily sorted. If you don't like the idea of a vehicle that has a diesel engine coupled with an automatic/semi automatic gearbox, then do not purchase one. If, on the other hand, you are a fickin stupid moron you think this combination is acceptable, then there are plenty out there to choose from.

No need to thank me. ;D

I'll stick the pickup in 4LO (and 4HI when I run out) tonight and pretend I have 12 gears, just for you ;)

(Actually I think if I tried to flip from 4LO to 4HI in 6th the gearbox would probably go bang.. or more likely the ECU will just beep at me)
You have a warranty, what's the worst that could happen not my car ::)

 ;D You can switch between 2HI & 4HI up to 60mph (although you have to dip the clutch, obviously).. I did try 4LO briefly.. hilarity ensued ;D

ok.. I said 2 things..


1 -  I dont like diesels and autos or combination
2 -  manuals consume less and accelerate faster.. statistically true and widely accepted fact..


any exception of automated manuals or rocket science trannies with XXXX gears wont change the fact


and this truth dont belong to me.. its universal..

93Kg including oil, so about 3x a Getrag 250 manual box but only about 13Kg heavier than the 4 speed 4L80E in the Omega.. not bad for twice as many gears.

yep.. I've checked that also.. 93 kg negligible on a car thats 250-300 hp and weighs more than 1600-1700 kg..


but still I would prefer the pre-historic manuals ;D :D


auto lovers may plan a swap , but will need deep pockets :-\

A diesel auto is, in my opinion, highly desirable. ....in theory.


However, ignoring the horrendous physics of running a fuel system at 450bar(7000odd psi :o )for a minute, my concern with a front wheel drive auto especially is, limited space between the front wheels means a transvers engine of a gay wheel drive means there simply isn't room to fit an auto box on the end of the engine WITHOUT OFFSETTING THE DRIVE LINE.

As you all know the omega is rear wheel drive and the engine is mounted pointing forwards. Not side ways. This means there is acres of room to fit an auto box on the end of the engine before the rear wheels and axle get in the way.

On a front wheel drive, you have to take the drive from the crank and make the drive go round corners to fit all the gears in between the road wheel and the end of the crank. This means extra weaknesses in the drive line of the auto gear box on front wheel drives that simply don't exist on rear wheel drives.

Then, add in the low down torque of a diesel,( which is bad for autos as we know from the omega tractors killing ar25's if chipped, and sometimes even if not chipped,) then we have even more potential for the torque of a diesel destroying the auto box.

Add in possibly towing, poor servicing, and an aggressive driving style on top of that,  and the odds of an auto seeing more than 60k on a front wheel drive diesel is, I would say, possibly reduced.

Some manufacturers are better than others of course, (Aisin Warner are exceptionally poor with plastic parts in the valve body) but imo, avoid a front wheel drive diesel auto, unless your prepared to do a great deal more research than asking on here in order to avoid a large bill for auto box repair.

Tread veeeeeery carefully, imo.

Heavy car, torquey engine, front wheel drive, auto box...... Bad idea, sadly. Although hopefully more modern autos have had the weaknesses engineered out by now. But how to know before buying?

...,, lift pumps on diesels often fail, £1500 quid odd? I don't like diesels.

Injectors, huge great things compared to petrol ones due the massive fuel pressure, BMW E39 ones are over £300 each (x6) to replace, and £90 each to refurb.

Numerous pumps in the fuel system to multiply the fuel pressure at each stage.

Need i go on?


Would add, I have zero experience of that particular car, so might not be relevant, but satisfy yourself of the reliability of that model.

Did I mention, I don't like diesels?

I'm agreeing with you. Don't knock it, it doesn't happen that often.
Now stop worrying about cars and start thinking about how you're going to get anyone to come to your Christmas party. ;D
