Velociti sensor replace + ECU reset

[TemoMK1]

Hi guys,

My 2007 velo 1.4 has started giving me terrible fuel consumption. It dropped to about 8.5km/l. I initially thought it could just be a bad batch of fuel but its been remaining the same for the last 3 tanks. The only visible change I've seen is my oil pressure light came on once or twice a month, but I've read that those sensors can go bad.

A buddy of mine raced a velociti and has since given me all of his spares. I will be replacing all the sensors (MAP, water temp, etc) the weekend. Must I reset the ECU after fitting the new sensors? And can it be reset without VAG software? The car will be going in for diagnostics next month, I just want to replace everything I can before then.

I have seen guys getting upwards of 600km on a tank, and Im struggling to get to 500km.

Any other advice or things to look for will be appreciated.

Thanks

No need to reset the ecu. But if you change the throttle body you should have it calibrated.
