hi
i have 2001 tdi 75 hp with full tank of diesel about 30 litres i am doing about 200 miles in town.i dont think its normal i was hoping much more than this
do you think something wrong
 
It doesn't sound great however I think you need to carry out a more accurate check (fill tank to brim, zero trip meter, run until needs refill, re-brim, check mileage and calulate). It would also help to know more about your city driving, journey length, is it all low speed, low gear, lots of stationarly engine idling stuff? Is the engine getting upto temperature? have you checked tyre pressures, brakes binding, have you had the A2 long? have you driven diesels before? Are you using branded fules? Try running some Redex or Millers additives for a few tanks. Sorry for all the seemingly unhelpful comments however annalysing such a problem is not straight forward. What car did you drive previously and what consumption did you get from that?

If the car is only used for city commuting it may simply need a good long fast cross country/motorway (100+ miles) run to blow away the cobwebs every few weeks.
 
Thats around 30mpg,if its stop start then its possible.
If your talking Urban/Extra Urban try changing gear before revs pick up and see if it makes a difference.
I drive 7 miles to work and this tank so far is giving me 59 mpg but its hard work.
If I drove Normally it would fall back to 47
 
thanks for your replay but i have checked almost everything i used to have bmw petrol i bought a2 for fuel saving. and i doesnt look great
there may be tecnical problem any idea ?
it just been serviced and belt changed
thanks
 
Get someone with VAgCom to do a diagnostics ( might be the MAF), and without wishing to offend a Diesel does require a different driving technique to get the best from them. A lot of drivers when switching to diesel still rev the rollocks of them. Gear change up points will be much lower down the rev range and when trickling through heavey traffic tickover will often be sufficient to pull the car along. Finally there is also the seasonal factor, the exceptionally long winter and low temperatures does adversely affect economy and this can be at least 10%.
 
Some times the deisel is not that good around town but you would find it more economical on a long run i find if i use mine just to and from work plus a little bit of running around i only get about 47 ish, but long runs i've had as much as 72.
