Post by: swordfish on 09 December 2017, 16:36:28
Anybody know the fuel consumption for the 2.2 dti
Thankyou

What sort of driving? Motorway? Town?

My old 2.2 DTi was an absolute cracker of a car. I could see 600-700 miles out of a tank no problem at all, and if I was careful on A roads, on my regular trips to Cheltenham, I'd see upwards of 50 miles per gallon without trying too hard.

Average was probably 43-45mpg.

If you're running a V6, you'll cut your running costs in half with a DTi. Nice amount of torque and ample power. I'd own one again in a heartbeat.

Bought mine for £180, only thing I ever had to do was an aux belt tensioner and a PAS pump, which were pennies at the scrappy. Went on to drive it to spain and tour around for thousands of miles, with roofbox and heavily loaded, never grumbled once.

It went to a good home after me - The only thing that killed it, eventually, was the old tin worm  :(

Ok Thanks ,,  and how well do they perform towards a omega  3.0 OR 3.2

And did they ever do them in Auto

£185  ;)

 ;D

I forgot that I bought it with a known fault. You’ve no idea how relieved I was that the revs
Issue was the clutch rather than the derv pump!

I did it on ramps in the street ;D wouldn’t contemplate that now :(

Practically the same torque, nowhere near the same BHP. Only really going anywhere when on the turbo so you tend to drive them like you stole them.

Whilst they have the torque, they certainly don't feel spritely like the V6 petrols.

Really easy to look after the 2.2DTi, much less temperamental than the V6s and everything is pretty easy to get to. Fuel system is the only special thing to make sure you look after well, otherwise utterly reliable.

Remap is very effective as are the usual mods to help the turbo spool up more easily. Standard trim, it's a bit of a plodder but perfectly OK. Post remap better performance, better real world fuel consumption and the engine runs more smoothly. Would never go back to a V6

ok Thankyou,, and how would you compare the bmw straight 6 tdi omega
Title: Re: omega 2.2 dti
Post by: ajsphead on 21 December 2017, 12:57:54
2.5 smoother in standard trim and sounds less like a tractor when cold, not as economical, actually has less torque in Omega spec than the 2.2 but can be remapped if paired to a manual box. Can be had with an auto box if you want but don't remap an auto, you'll exceed the torque rating and blow up the box.

Engine bay way more congested. Getting pretty long in the tooth now and read the web pages for applications in BMW and Range Rover to get a good idea of common problems.

Can't really see the point as my remapped 2.2 is more powerful than the factory 2.5DTi that we never had in the UK and I have genuinely exceeded the manufacturers best fuel consumption figures and I can get at pretty much everything really easily to look after it.

ok thankyou,,
Can you possibly tell me the fuel consumption since you have had it remapped   
Title: Re: omega 2.2 dti
Post by: ajsphead on 22 December 2017, 07:25:42
No problem

average 40.4
best over 1000 miles 49.8 (manufacturer's best is 48.7)

This is brim to brim manual calculation, not using the trip computer at all.

ok thanks ,,
was it expensive to get it remapped

remap and EGR delete by reputable company local to me (Avon tuning) cost £350, but less to me as an existing customer. Whatever you do don't let a tuner increase the fuel pressure unless you want to take a risk with the fuel pump - they can blow internal seals and then get rather costly to fix.

The two I owned I got the internals removed out of the cat, this helped a little with the lethargic acceleration from standstill and made the exhaust system a lot more free flowing.

Have left the cat on mine but replaced everything else with an unbaffled 2 1/2" system from the cat outlet back. Has had a similar effect. Have also shortened and re-routed the air inlet to ensure the coldest air possible and the shortest route to the turbo using the original components to keep the look right.

.....just to add to the praise for the 2.2 dti here. I have had my estate for 9 years now & it has been a brilliant car.
It's spacious, economical & comfortable. I don't plan on replacing it ever!

I'm interested to know...how much of a difference do these modifications make?

Slight improvement in fuel consumption, slight increase in noise, I prefer to hear the engine on my cars, and a little cough on overrun to add to the character. Shortening the air inlet really helped initial pickup as did de-restricting the airbox and changing the air filter for a free flow type. The best intake design for a N/A petrol engine is not the best design for a turbo diesel, so some research on turbo engines led me to the solution I have.

Finish with remap and EGR delete to maximise reasonable potential and clean up the emissions by no longer having to chew on its own effluent and I'm pretty impressed. Once warmed up,  I can now cruise at 32mph in top gear with no juddering. Smoke test was very good 30ppm at full throttle and sit at 70ish on the motoway in top and floor the throttle and I think a 3.2 would struggle to keep up.

One or two words of caution. Not every car responds the same way, mine seems to be much happier but there's no guarantee others will and, you may find you are at the torque limit of the clutch, and hence also quite close to the torque limit of the gearbox too.

Is it worth it? Yes absolutely for the improvement in refinement and performance but like everything it has to be done properly by clever reputable people and does carry a small element of risk.

I like the sound of that.
Any info would be really appreciated.
Where do I start if I want to shorten & reroute the air inlet?

Sorry, just thought....do you have any pictures of what you've done?
