Hi All.

On a run I average about 42mpg with my PD Tdi Vrs Estate, 56reg, 33k, air filter replaced at every 10k.

Any ideas what could be the issue, no stored codes, all Dealer updates done too.

At this rate I am not far off the petrol version mpg ( or is this normal?)

Many thanks

Kind Regards

Just done 2000+miles to Austria and back 70/80 mph--averaged 51mpg not what maxidot said though it was way out at 47mpg,i worked it out with calculator....

Have you checked your mpg over several brim to brims by spreadsheet or spritmonitor? In my PD170, the maxidot mpg figure is ~3.5% lower than actual. So you might be doing 43.5mpg. Depending on your driving style that's not crazily low for this car.

The best cold start, whole journey figures I've had from mine when driving for economy (that's not to say stupidly slowly) are 60mpg over 25 miles from near bakewell to sheffield and 58mpg from coventry to sheffield up the m1 (100 miles). French Alps to Belgium (550 miles) fully laden was 50mpg. It's not as easy an engine to drive economically as my old 1.9 PD105 - getting the gearing right around town is a fine balance.

What mpg do you get for the same journey in your Fabia?

Are you doing miles on the motorway or in an urban environment? Stop starting will being the figure down a lot.

42mpg doesn't sound too far off the mark from other posts. About 10mpg more than the TFSI.

That's about what I get from mine in mixed driving.

Although you say that it's not far off the petrol, I suspect you'd only be getting low 30's doing the sort of trips your doing in the diesel to get 42 mpg. A 10 mpg difference between petrol and diesel is about the norm.

I think the CR is more economical then the PD engine. My wifes Yeti 170CR gets mid to high 40's on journeys that I get low to mid 40's when driven in a similar manner.

My 140PD when I had my Octy (OK not exactly the same engine . . . ) struggled to average anything above about 44mpg. Motorway journeys (not straying much above 70mph) would usually only return high 40's, it was certainly an effort to get above 50mpg. I was a bit annoyed given the claims of 50+ mpg average (something my old 1.9tdi Fabia did always manage to return).

On average i get about 49.5 mpg from my pd. on a good motorway run i can get 56.7mpg.

BUT i use bp ultimate diesel and i have induction kit fitted

My PD vRS averaged around 42 mpg over the time I had it (worked out by hand, the trip computer indicated slightly less).

My CR vRS is averaging slightly more than this, but this has only been over 4000 miles from new at the coldest time of the year. It is already improving with the weather, and as the engine fees up. The trip computer is about 6% optimistic, so 51 mpg indicated works out as 48 mpg actual.

More motorway/A road mileage improves the mpg figures quite quickly.

Pretty good for a 170 hp car with loads of torque, and loads of room IMHO

42 mpg is normal for a TDI PD vRS. Don't believe what you read in the manufacturers figures. Always makes me smile when I read car mag long term test reprots. The mpg figures they get are usually about 40% less than the manufacturers claim.

Welcome to the world of surprised at mpg !!

You are getting almost exactly the same as me mate,,,astounded at the difference between fabia vrs and octy vrs,,fabia was easily 57mpg octy barely gets above 43mpg, even on 500 mile motorway runs. Sure if you dawdle along at 65, you will get more,,,but who does that??

Nowt wrong with your car mate, just drinks more than others.

To be fair, if I get anything above about 80% of the manufacturers quoted combined mpg I'm happy.

The last 3 cars I've driven have all been quoted 49-50mpg, the X-Type struggled to do 40mpg and the Saabs got 43mpg (Saloon) and 42mpg (Estate) with me driving them.

I'm getting about 42mpg at the minute from the vRS (quoted as 47) so not too bad, especially for a car as quick as it is.

I'm sure if I modified my driving style I would get closer to or even exceed the published figures, but that just ain't gonna happen

That's the point really. If you drive around like you've got 12 points on your license then you'll get mid 50's mpg, but in that case you may as well px it for a 105PD and get 65mpg!

I don't think low to mid 40's is too bad for the car given it's performance and how often it encourages you to use it.

I agree. There's nowt wrong with it.

My 25 mile each way commute, mostly motorway but with some traffic (M62/M60) and a bit of town at either end ususally brings in something between 40-45mpg on maxidot, depending on how much clear air I get and how much of a rush I'm in...

If I pootle then I can get low-mid 50s mpg, but as others have said, why would I buy a 170bhp car and then drive it for economy?

Quoted figures are nonsense anyway, and the sooner people disregard them when buying a car, the hapier we will all be.

i get around 38-40 mpg in mine, but it's a 20 mile trip mixed drinving with about 15 roundabouts/junctions so im constantly hammering it back up from 30 - 70 (ish) mph

On a gentle run i get 42-44 mpg

44mpg average over the last 30,000 miles- about 500 from a tank. do a few long runs would be under 40mpg with urban driving.

My old nissan primera diesel would do 50mpg but only put out 75bhp- so 6mpg less for an extra 100 bhp is not bad

Whats the range you have driven on a full tank, with my old PD140 octy I always got 550 miles which is a mix of town and motorway. My PD140 superb gets 450 miles out of a bigger tank.

2 x different VRS's over 2 years, one PD one CR both average 42 mpg (all types of roads).

Hiya mac, yep funny you should start this topic. I've been thinking about my economy a bit lately on my octy vrs. I've got

tdi pd 57-plate, only done 30k miles and I was only getting about 44 mpg at very best. My daily commute is a 90-mile round trip

on mainly motorway and A-roads/quiet B-roads. Even when i drive it like a girl i can't get it above 44.5 mpg!

I have to say i've been really disappointed with the fuel economy on it. Considering i was getting 51/52 mpg on my furby vrs doing the

same journey but driving harder!!

However i've done something about it, i've gone and had a DPT Diesel module installed and my mpg has increased to 48mpg. Only had the

thing fitted for 4 or 5 days and economy is steadily improving. Time will tell if this device is a worthwhile solution to improving fuel economy.

However i've done something about it, i've gone and had a DPT Diesel module installed

Hope that doesn't cause you any long term problems. I wouldn't want to use a tuning box on a PD170.

I was happy to get 29mpg out of my 170 cr dsg estate this moring. It has to be all about how you are driving it. That was taking my wife to work in Paris rush hour. The car says 47.1 mpg on it long term and again I am happy with that.

Why wouldn't you want to be using a tuning box on a pd170 engine? These engines are bullet-proof. You have to seriously stuff around with your engine

and its control system electronics to damage the pd engine.

The box manufacturer has insurance to cover you in the rare event there is engine damage from the box and they provide a 3 year warranty on the box

itself. I've not read too many complaints about this particular brand of tuning box.

Are you talking from experience about pd170 engines?

You're increasing the soot content of the exhaust on an car with a DPF setup that's already not the most reliable even without mods.

Yep fair point. I noticed before i fitted the tdi module though that the dpf regen occured on my octy 2 or 3 times a week anyway. It isn't doing anymore

than usual with the module fitted. Although to be fair, i have only had the module fitted for 1 week. I do a 90-mile daily motorway/a-road commute everyday.

Time will tell how the dpf reacts. The installer of my module warned me not to 'overboost' by over adjustment of the tdi module. He said if soot appears

from the exhaust then i should 'wind' it down a touch until the soot disappears. I believe this guy (who tunes/remaps cars for a living etc) may have developed

a dpf-cleaning service, but i think he it is still being trialled and developed.

Just as a quick comparrison, I drive Dual carriageways and town traffic for about 13 miles to and from work. I've got the 2.0 Petrol vRS, and avaerage about 25-30 mpg on that journey. If I thrash the hell out of it, more like 20. I noticed today, on cruise at 70-75 it was a HUGE 45 mpg. I'll normally have to fill the tank from full after 300-350 miles.

I do sometimes wish I'd gone for the 170 cr, but then I get such a wonderful turbo'd petrol sound from it that I can forgive the thirsty habits!!!!!
