I have recently purchased a Tdi90 in addition to my beloved TDi75. I have noticed a marked difference in the diesel consumption!!! The 90 is loads more thirsty than the 75.
Is this normal?
How can i make the Tdi 90 more economical i.e. engine remapping, gear ratios, reduce the power?? can this even be done?
Anyone know where I can do it, if its possible ?
Also the 90 is making a hissing noise when I accelerate. Is this the turbo or air suction? its worrying as the 75 does not do this, is it normal?
