2.0 TDI 170 Fuel Consumption

Surely the dealer must be able to say why this is ??

Is this manual or tiptronic?

Not sure what the gearing is like on the 2.0TDI but on mine I can sit at 80mph with about 2,100RPM in 6th

Have owned Golf 90, Golf 110, Golf 115, A4 130, A4 140 & now A4 170 TDIs. Very disappointed with fuel consumption (weighed against performance) of the A4 170 compared to others. Still own a Golf GT TDI 115 and can hit 60mpg on a long trip. Only have done 5k in the A4 170, and was hoping that things would improve, but reading this thread, it doesnt look like it. Might it be worth re-tuning if Audi say that there is no issue?

I dont think its just the 170 BHP engine, I think it is the 2.0 engine in general. I had a TDI 130 before and this was very frugal driven the same way.

I have an a3 20.tdi 140 (18k miles)and i am also very dissapointed with my economy. I had a 130 tdi golf before and that would reguarly give well over 50 mpg on a long run sticking below 80. the a3 struggles to give mid to low 40's at these speeds. I think the golf trip over read but even taking this into account it was still well above the audi.

Two people at work also have a3 tdi 140's, one which is the same age as mine gives even worse economy but the other is about a year older and this gives economy similar to the golf. I believe that they revised the engines to reduce the emissions so maybe this is the cause??

Another colleague has a 170 tdi a4 and he gets mid 30's for his economy.

There are many variants of the 2.0 TDI engine, mine is a BRE prefix engine. Someone a while ago told me that it was the EGR setup on these engines that was to blame.

I have an A4 170 TDI 56 plate with an engine re-map and was also disappointed with fule consumption returning only 38ish on a long run with speeds around 80mph. However she had her first service last week with 19K on the clock (few other problems invited an early service) and earlier this week took the family upto LegoLand!! which is about an hour and a half motorway run from my place and was very pleased to see a journey avarage of 46mph. I must say we cruised at between 75 and 80 nearly all the way so stoping and starting but still a vast improvement. I have also noticed a marked improvement on shorter journeys say from home to work which for me is only 5 miles.
So suggest you look forward to cars first service and then would be interested to here if like wise you see major improvement!!!

funnily enough it's got its first service on tuesday.

It's been in twice now for a knackered heating fan and haven't mentioned economy before cos i assumed they'd just put it down to my driving style or the weather, but i think i will now. - thanks for that.
