Mine will average anywhere between 46 and 52 on a motorway run (dependent on speed) and will only return high 30's around the doors.

Has anyone had any experience with the 150 TDI in 2 Liter?

 

Just wondering wehat the real economy is like.

 

Two adults 2 toddlers and boot packed we get 55mpg long distance keeping 70-75mph. My 10 mile work commute I get 50mpg, although when it was -5ºC I only got 40mpg. Best I've seen is 65mpg, although only in ideal conditions, just me, and free flowing level A-roads.

 

The main problem I find is that driving economically seems to make the car perform DPF regenerations more regularly which heavily offsets the fuel saving of driving carefully so I figure may as well use the power.

 

The main reason for not going with the 1.6 TDI was the fact it was only available as a 5sp (I don't know about now), it's arse about face the less powerful engine naturally benefits from more ratios. Given I'm being careful due to 6points the 1.6tdi would probably have been enough and I've heard is noticeably better on fuel.

 

Ps) The chassis can barely handle full throttle in first, wheel(s) tramping and spinning very easily. 225/45 R17.

 

Pps) The diesels are much cheaper on personal lease than the petrols.

I take it yours is a manual returning those figures?

 

Interestingly, mine seems to perform a high amount of regens, and as you say that massively hurts economy. I've never driven a car that has so many regens, and so noticeably too!

Sadly I think common concensus is that the super and turbo charged 1.4 engine was a failure.

If you mean the latest 150 ACT 1.4 which my son has in his Leon FR, I hope you!re wrong. It is a great engine, quick and smooth, returning high 40's and occasionally he sends me smug pictures of 50+Mpg.

Nope - the older iron block 1.4 which was available in 150, 160, 170, 180 and 185PS (Audi figure manipulation) guises and bears little/no resemblance to the current ACT engine, apart from being a "1.4".  Some engines suffered shocking oil consumption and cost VAG a lot in warranty claims.  Technically, a wonderful engine though.  I mourn its loss.

 

I've regularly managed over 50mpg on my ACT-engined Leon - like your son, I'm averaging high 40's

VAG engines aren't the best to be honest. I hope my 1.2 TSI isnt going to give problems out of warranty.

They seem to design a new engine, have a load of problems with it and then bin it after 5 years.

The older TSi timing chains and the twin charger model spring to mind.

Mind you BMW aren't much better the manifold flap problems on the 4 & 6 cylinder diesels and timing chain problems on the Mini/Peugeot engine.

That ain't too great to be honest.

I'm not the most economical driver in the world it must be said!

I've got a 1.2 and very pleased with it. My long term average is 40mpg but my 25minute / 5 mile commute consists mostly of queueing to get into Oxford and queueing to get out again! It's true a diesel might be more economical but I was concerned sbout the lifespan of the dpf if I carried on like that.

150 AWD here

 

Ps) The chassis can barely handle full throttle in first, wheel(s) tramping and spinning very easily. 225/45 R17.

 

The AWD completely removes any tramping/spinning even on wet roads. On the other side, my fuel consumption is higher (today my average was at 49.5mpg).

 

It must be said that my engine has just a bit above 10.000 miles and I like to stomp my feet (when the oil is well warm >80*C).

 

HTH,

you'd have to go SE-L trim to get the 1.4.

The 1.4 is also available on the SE.

Iv got a 1.4 tsi 180 bhp I'm glad to be trading it in not had any problems with it but not done the mileage iv only just done 20000 in it its oil thirsty if you read all the forums there are plenty of oil consumption problems not shaw about on here though the earlier engines are the worst apparently

That's a different 1.4 than the ones fitted in the Octavia.

Yep - some confusion of 1.4 engines!

Yes, 6sp manual, elegance estate, 7k miles now. Is it possible to set the dsg to sport to see if it regenerates less?

 

Ps) I turn the can off if it's regenerating whilst stationary, I do enough miles on the motorway that it can regenerate then.

Thats the problem though, motorway speeds cool the DPF too much hence, it'll annoy the F outta ya by doing a regen a couple of moments after you've left the motorway !!!

Doesn't really matter where the regens happen, it's just they're way too often and it kills economy when they do happen.

I never ever once noticed my Mazda 6 or F20 1 series doing a regen!

That's very inaccurate, the motorway is the best place for a regen to take place the continuous loading is ideal to allow the heat to build up, the manual specifically states a minimum speed and minimum rpm, both of which are satisfied on the motorway.

I refer to this from the AA (for those around the world who might not know, Automobile Association)  http://www.theaa.com/motoring_advice/fuels-and-environment/diesel-particulate-filters.html

 

Go down to the section AA experience and you will see " We're seeing some evidence of DPF systems failing to regenerate even on cars used mainly on motorways" they also go on to explain why.

Quote from link: Passive regeneration  

Passive regeneration takes place automatically on motorway or fast A-road runs when the exhaust temperature is high

AA experience

We're seeing some evidence of DPF systems failing to regenerate even on cars used mainly on motorways.

On cars with a very high sixth gear the engine revs may be too low to generate sufficient exhaust temperature for regeneration. Occasional driving in a lower gear to maintain around 2,000rpm should be sufficient to burn off the soot in such cases (refer to the vehicle handbook).

 

:end quote

 

Whilst I don't know each and every models gear ratios, 70mph in 6th satisfies the manual's stated requirements for active regeneration, as well as that for passive regeneration. I would assume my 2.0Tdi is probably the highest geared Octavia so that would cover the 1.6 diesels as well?

What are the recommended speed and rpm?

 

From memory, whilst active regeneration is taking place (essentially you have to guess when this is as you are not told and the gear indicator does not modify it's behaviour) constantly above 50Km/h and 1800rpm.

I don't care what the handbook says the cooling effect of moving at 70mph+ will stop regens, it's just physics.
