99.9mpg on a VR6

[quicky1980 0]

Ive recently fitted a vr6 engine into my car, and after finding out the speedo didnt work (faulty gearbox) I swapped the gearbox and sorted that issue out. Now while I was driving around with the faulty gearbox I didnt have the fuel consumption reading on my instrument cluster, I put this down to the speedo not working.

 

So I now have a working speedo, but mpg reads 99.9mpg. Ive looked this up on the forum and people say its the purple wire behind the dash/fuse box. Ive looked this up and all seems to be connected properly. Could it be anything else?

 

Im using a golf vr6 ecu which vince at stealth remaped to a corrod spec. cant say for sure if the clusters mpg is working due to it being fitted while the engine was swapped. dont want to be swapping stuff again if it could be something more simple that ive missed

thanks

to be honest i gave up..nothing showed up on VAGCOM and its only a rough guide anyways and everything else on the MFA works perfectly so just decided to focus time on other things..let me know if you ever do find out though.

just out of interest, what does that vacum hose on the back of the clocks do? tah

[Critical_Mass 10]

Its for the mpg, works it out using manifold pressures.............. i think.

[VW_OwneR_85 1]

no never got to the bottom of this so ended up fitting a 3.2 v6 instead lol

 

if you have a vacuum pipe on the back of the clocks it sounds like you have a non vr rado. check its connected to the ecu and has no leaks or splits
