Thread: TD5 fuel economy

If you drive it the same, then it should drop. But you get increased power, which is always tempting to use.

BTW: See if Tombie still does remaps, I have one of his and it transformed the car.

for 2.5t of slab sided metal i would be very happy with that.

i have a chip and 245/75 muddies and am getting around 11.5 mixed town/country driving.

saying that just did a 330km day trip sydney/wollongong/sydney in the wifes tdi golf, 6.4ltr/100km.

Hi,

I have a chipped D2 TD5. I asked the prior owner and he says it came from South Australia Rover something. He says they are very well known, I think it is TRS like you are planning on getting.

The previous owner swears the car will do a four wheel burn-out. I believe him I'm just not prepared to try.

We drive very very conservatively and we have shocking economy. I cant work out exactly what it is because we have a doggy fuel gauge.

I try to work out my milage by filling up to the top and driving 300 kms or so and then filling up again. I average 45 litres for a 300km trip.

That's about 15ltrs/100..It has been worse than that also.

Aircon off. Gentle acceleration, 100kms on highway etc etc etc .

I love my car but I hate the consumption.

I am seriously considering put a stock ecu in.

Cheers

Try being less nice to it. Diesels need to be worked. If you're really gentle you'll just end up glazing the bores and consumption won't be good.

I always got better economy when I wasn't as nice!

Many thanks. Sounds like my economy isn't that bad after all. Can't expect it to be as economical as a golf, but I was hoping for under 10 l/100km. My thoughts with the chips are that if they make more power, it has to come from somewhere, and unless you fiddle with cylinder heads, turbos, intercoolers etc, I guess it comes from burning more fuel. The extra power would be very nice, but I was hoping that a chip would not really affect cruising economy, only if you put your foot down.

It wont effect economy if driven sensibly..

Improved torque helps get the vehicle moving, resulting in less fuel used for easier driving.

TD5s are under tuned. Tuning them makes them much nicer to drive...

I dream about economy that good!

Borrow a standard ECU and try it. You may find that it is neither teh ECU or tune that is the issue. That is the scenario I have.

If you do get it chipped, make sure that you monitor your EGT's.
I could get mine above 900 deg. C quite easily. I have chosen to remove the chip( to save the turbo)and found that the auto in mine is much more responsive to the motor now that the chip has been removed.
