Ideal, thanks, very helpful.

The SDI is not the most efficient engine out there, the 1.4 tdi will use less fuel, but both will use a lot more fuel then a 1.9tdi in a golf etc (VE or PD engine) if you rag it and carry loads of weight, so dont by the SDI expecting 70mpg, you wont get it, not unless you live on a marsh and are prepared to go stupid slow. The main reason the 3L uses so little fuel is it weight is very low, the engine is very light also, the car has a small TDI engine with variable vain turbo, unlike the 1.4tdi, note TDI not SDI, and has a computer controling the gear box, including putting the car into cruise, ie not in gear. the clutch on the sdi is cable and very heavy to keep knocking in and out of gear. people will tell you they get this mpg and that mpg and about so many miles per tank, but unless you track every tank you wont know. I have an SDI and I have had it chiped as the SDI without it is not a safe car for moden day traffic. I get about 55mpg and I dont get in other drivers way but I had a mk3 tdi golf estate with 120hp and got 50mpg. For what I lost in space and power, the sdi economy is not much of a saving. oh and heres the evidance: http://www.fuelly.com/driver/otherpower/golf http://www.fuelly.com/driver/otherpower/lupo Cheers Jon

If you have a tray, keep it on, they keep crap out the engin bay, make things quiter, help improve fuel economy and handling at speed. Cheers Jon

The nut was lose, cant be much left the last owner didnt tighten up propper tight like. Cheers Jon

What milage is it, do you know the history of the car, what wheels do you have on it? What engin lupo did you have before? I would say, put the right oil in it (fully synthetic 10W30 - for PD) and do the filter. Clean out the inlet mainifold and block off the EGR. RAG IT for a bit (20 miles once hot) after doing the above, get the engine to breath, really rev it and get it hot. Cheers Jon

Lost the last tank, the tank befor that was ~54mpg and I did go a bit faster. I have just changed the oil now, we shall see for this tank. Cheers Jon

I know who owned it before me, I am 95% sure its losse, we shall see

Dent out, Can you take a picture of your setup please? Jon

Theres an additional switch on the brakes to stop left foot braking and to kill cruise control, you can just unplug it, pull it out the way, if your driving that fast dont crash. Jon

Hello, I need to do the steering nut up on my wheel as its losse, not fun. Can someone tell me what screw head it is on the screws holding the air bag on please? Thanks Jon

Well the last tank is in, 347 miles ~ 55mpg, still nothing to write home about. I must get my thermostat done though as temperature is sitting at 75. The chip is helping out, I am feeling safer in the car. Looking at my dash cam videos, in third I am almost flying with the increase in power Going to set the laptop and VCDS up tomorrow and see if I can work out best speed VS economy for the car. I would like to put steelies on but all the tyres are good on my alloys and I would have to save a lot of fuel to make my money back. Ill keep up dating this with my tank mpg. Cheers Jon

Forget the boxes, they just mess with the engine sensors. I can give you the email of a guy who will sell you a chip that is a propper re map for £40. To be honest though, I came from 115hp to now 70hp and that was bad enough so a drop from 172hp must drive you crazy. Cheers Jon

I have an UltraGauge but the MPG setting is crap it geusses widley, manafactures not fused about it at all. I go by %foot pedal. I will take a picture.

Hazy, do you think the difference in the cost between 10W40 and 5W30 will be saved in improved economy? What do you think to engine flush when changing the oil? Jon
