Hello All,
I am thinking of buying a Diesel Omega as my petrol bus is looking a bit sorry for itself and is probably going.
Thinking of diesel for obvious reasons, are the diesel Omegas any good? I am thinking of looking at a 2.5 elite diesel Estate from 1999, 135k priced at just under £1,500. Is this a good car to have? its in good shape, one owner until the dealer got it. What questions to ask, would be a good start. Are these fellas' cams chain driven? BMW? I have no idea and no time to search for details right now.
Any help Grately appreciated!

I won't be much help but I can say I would not pay that much for a car of that age and mileage. The 2.5 is a bmw engine but chipped to produce less power. It can be re chipped to increase the power, but if auto needs areplacement auto gearbox.
HTH
Also I hate diesels with a passion so I am biased :y
Also there is study going on at the moment into the decline of bees. and it looks like diesel particulates could be to blame.

Hiya fella, have to agree it does seem pricey but if its from a dealer then..........
You're right in that the 2.5TD lumps are chain driven which will last well if oil changes are kept up. A chip change does get them to around 170Bhp. Can't help much more than that but hopefullt one of the tractor/taxi diesel owners will pop along soon. Good luck in your hunt :y

If looking for a 2.5TD I would avoid automatic gearboxes and hold out for a manual. As said, the auto boxes are too weak to stand chipping and, TBH, are marginal when the engine is not chipped so one with the sort of mileage that's likely these days will have a tired gearbox anyway.
Other than that, they are chain driven but that doesn't mean they take previous neglect well. They have a short service interval of only 4500 miles and need oil changes at this interval to survive, so avoid anything that has not been treated well in this respect. Cooling problems are often the first symptom of neglect so avoid anything that is running hot or shows evidence of boiling over, or poor coolant servicing.
This engine was superseded by the 2.2DTi. Less refined, being a 4 pot, and not as quick. Only available in manual but you will be able to find newer examples of these.
I too think it'd be unlikely to be worth over £1k unless exceptional, but I must admit I don't follow the values of the TDs that closely, and if it's from a dealer and in good condition, I suppose that's what you'd expect to be paying once he's made his money on it. :-\
The other thing to bear in mind is that the Omega diesels are all relatively aged engine designs. They will be better on fuel than their petrol counterparts but nowhere near the economy and performance that a more modern diesel can deliver. I'm guessing a little here but I would be surprised if a 2.5TD would deliver much better than 30MPG around town and low 40's on a run.

And an automatic (from experience) is little better than a 3.2V6.

First thing to do before you buy is paperclip test it to see if any codes are lurking :y

Its a pity your after an estate ::)

;DAs i only buy diesel estates, i reckon the price is about right if the car is clean!! :y
-
Thank you all for the response!
Now I know a little more, I think I will give this one a miss. It did seem a bit pricey, although it does look very clean. I would consider a saloon,(prefer estates though) and we do want an auto, so the later diesels are out it seems. I guess I will have to keep looking. :-\
Thanks again!

I bought a 1998 Diesel estate on e bay last november for £331 with 6months mot it only needed a track rod end and a new handbrake cable for its next mot less than £50 and apart from a service and glowplugs and leak off pipework replacement has been reliable :y
