Having jumped from the mk2 octivia diesel to the mk3 diesel I find that the moment 3 seems to be a lot more thirsty than the most 2. Has any one noticed that? 

The mk2 was a manual and the mk 3 is an dsg

Would that be because the Mk2 was Euro 4 emission and the Mk3 Euro 5 and the Euro 4's had defeat devices, ie a cheat to pass EU testing.

ive got no idea!

They’re not comparable at all

All mk3's are either Euro5 or 6 using the later 288 engine.

 

The Euro 5 188 engine that can be found in the Mk2 had the cheat software and required the emission recall.

 

No Euro 4 engines are implicated.

 

Ok, so same thing, different numbers Mk2 with defeat device / Engine Management / Software and Mk3 not running iffy, well not the Skoda,

just some VW. Audi SEAT's, Implausible / Irregular Co2 g/km emissions.

When comparing manual v DSG diesels.

 

2.0TDi 6 speed manual is more economical than 6 speed wet clutch DSG

 

1.6TDi 5 speed manual is less economical than 7 speed dry clutch DSG

I've got a manual 2.0tdi MK3 and when I got it as a two and a half year old I was getting 50-55mpg, now a year and a half later it's improved to 55-60mpg. So it might take a while for yours to loosen up a bit?

Would be useful to post the actual différences you are seeing & the engine you had now/before & how long have you owned it?

Typically a DSG will use more fuel than manual with the exception of small engines where you can have 5vs6or7 gears as LogicLee said.

 

From the OEM figures, I'm sure the mk3 should be better than the mk2, however for me a lot dépends on how you drive.

I didnt have a mk2 but for me the mk3 has a very agressive accelerator pedal so you get a lot of performance with small pedal inputs which obviously has a detrimental effect on fuel economy.

 

From the forum there are big variations between fuel figures low-40s to 60s for the 2L for example & I think this variation must mostly be down to usage & driving style.

 

Previously had a MK2 1.9tdi and at its peak could achieve well over 60mpg with the odd 'grandad' effort to 70. Now the MK3 2.0tdi (dsg) is just about getting over 50 regularly since getting it in October (was a 64 plate with 38k). The whole engine bedding in theory with modern engines is not as applicable now. Getting used to the car/engine characteristics is a much bigger player in how many mpg you get imo.

Run it in eco mode, no aggressive pedal then

My Scout is now 3 yrs old, and with 40k+ on the clock my commute average mpg, with the right traffic and atmospheric conditions will average 60mpg.

Did your previous mk2 1.9pd have a DPF fitted?

Depending on your usual journey type then regens on the 2.0tdi can be a consumption killer

No dpf in the old car. This is based on 5+years of commuting and other regular longer journeys and then the same routine since October in the newer car. It's as close to comparable as you can get without being fully scientific.

I do a motorway run of at least 120 miles 3 of 4 weekends in a month so dpf shouldn't be an issue. Shouldn't......

 Unless it's my 2.0 dsg estate, it is uber sensitive. On the A roads, it pulls like a train even in eco mode. I always leave it in eco mode, only pulling back on the gear lever to kick it in to sports mode if required. I quite often see a return of 55+mpg however this can reduce with a more spirited driving style

I'm driving a 1.6 tdi  dsg and always have it in eco & really have to press the pedal to get any acceleration or get it to drop a gear. Must be some difference in the ECU settings.

That is right difference in the ECU, so the engine management totally different because it is a 1.6 TDI with less PS, and the Torque that means you get a 7 speed twin dry clutch DSG.

My previous Octavia SE L estate was the 1.6 derv with the 7 speed DSG, I had the same experience as you are. However moving up to the newer 2.0 derv 6 speed DSG with the improved torque makes for a huge difference between the two. Fuel economy is lower, as is to be expected. Ohhhhhhhh well

I never use eco on our 1.6TDi because it's to unresponsive.

 

Normal is economical enough though.

My 2.0 TDi DSG vRS can give very respectable economy if you treat it right 

 

 

I tend to average about 48-50 MPG with it, long term average this year so far over 15k miles has been 48.1 MPG.

I once parked for a walk at the top a very long hill in the Peak District, when I had got to the bottom after the walk, the maxidot was displaying 102.9 mpg, by the time I'd gotten home it was back to 65 ish as usual. I often see better results after I have stopped off for a walk on my way home. The first part of my commute must be the worst for economy.

That was achieved on a journey from Wrexham to Colwyn Bay on a quiet day, which was handy. I live on the coast, a few feet up from sea level and my commute begins by trudging up a massive hill away from the coast toward the A55. Annoying for the engine and box first thing in the morning, but it’s pretty flat all the way then except Rhuallt hill

I noticed the same when going from my Oct 2 manual Scout to Oct 3 manual Scout - both Diesel.

 

i used to get 65mpg on way into work but now it's between 53 and 63.  Granted engines are different etc but I put the variances down to it doing regens.  In All I reckon 80 - 100 miles less per tank on normal driving, range when re-fuelling backs up my calculation.

That's because it hasn't got any power to give (115bhp)!

No doubt, it is because of the colour!
