Hello folks been busy and not on site for a while but looking for advice on subject that may have already been covered.

My wifes car (VW 140 PD Tdi)has gone and new Seat Altea ecomotive has arrived. The trouble is very poor economy. We have covered 3000 miles so far on long flat 72 mile each way commute. Further to this we are both advanced drivers and aware of best driving practises re ensuring best fuel ecomomy. We averaged 54.2 mpg in old PD engine and now only getting 45.6 mpg in new car!!!! So all advice would be great!!!

Something not right there if I sit at 50 mph on the motorway with cruise on I have seen hi 60s to low 70s mpg. Even short journeys I'm getting 52-55 mpg.

Had a Leon Ecomotive when my Toledo was in for service and I found the ecomotive so ridicously high geared I found myself driving it to the red line rather than just a few hundred rpm in to the power band and then changing.

This is a common feature when going from normal to eco versions which I am expect you realise as a advanced driver.

Two other major factors.

New diesel still "tight" and not carboned in which can take 20 or 30 thousand miles and was your old VW a lighter car ie based on the smaller lighter Mk4 Gold rather than the larger, heavier Mk 5 Golf because that makes a difference too? Scout particularly so with extra bits.

Recently got rid of an Altea 1.9 PD and that never gave me above 44mpg whilst driving sedately, usually averaging around 41 mpg. Okay not the eco model but I always expected more from the car due to the shape and size! I drove the car for 67,000 miles from new.

Thanks every one for thoughts her old car was a 2007 plate Jetta which I would guess is same size/weight at Altea. If this is a fault rather than driver error which I think it is, has anybody heard of a software update to sort problem or it it just time to talk wife into the future and be a two car Skoda family!!

There has been a huge amount of discussion over on the Fabia forum with regards the 1.6CR fuel economy. It is fairly easy now to get 60mpg out of my Fabia on normal driving but it has taken nigh on 9000 miles to achieve this! The engine takes a lot of running in before it achieve optimum economy.

Stick with it as its a great engine. I will say however that you need to drive the car more like a petrol rather than like the old TDi PD units.

Wander over to the Fabia forum and find out more!

Thanks for this will have a look

The wifes got an altea 2.0 tdi, approx 44mpg over about 30k. I think its the shape.... My car has the 140 cr engine at thats getting better as the miles build up, now on 8k.

Hope that helps.

I just got a Octavia Estate Greenline with the same engine as you can see I'm getting a bit more than you. My commute is about half yours but sounds similar. Best I've seen from the OBC is 82mpg on a run - worst about 60mpg.

Interesting discussion. I run a 1.9Tdi Roomster 56 (non DPF obviously) plate and my overall average consumption is 52mpg. We've just taken delivery of an Altea XL 1.6 ecomotive with 10,000 miles on the clock to replace an Alhambra 2 Litre Ecomotive and it's a very different proposition.

With the DPF,on motorway runs I know I have to spend 15 minute spells at 2000 revs at least once a week to keep it clear. That means clear runs at 70 mph in 5th at 2100 revs Today I ran for an hour at 70 mph on cruise on the northern M6 and the display read out between 52 and 54 MPG. Obviously the gradients between Preston and Kendal are quite extreme. Is this acceptable at 70 mph? I suppose it's OK.

However, I could run at 55mph in 5th at about 1400 revs. I presume the MPG would improve, but would I end up with a blocked DPF if i do it for long enough? Or do I run at 2100 revs in 4th at about 55 mph? Presumably I'd get about the same as running at 70 mph, 52 to 54 mph?

Or do I just say, 52 to 54mpg from a large family car is fine so worry about other things? Obsession is an odd thing.
