Last weekend I cut the overheating crimped terminal off the alternator/battery cable and managed to solder it back on. Charging and starting are much better now :y

I was hoping (am hoping?) that sorting the charging out would magically improve the fuel consumption so I have been checking the live data.

The first thing that cropped up was an 0420 code. After I had cleared it I realised that I hadn't noticed a warning light. Does the ECU in the 3.2 store pre-codes? :-\

Today I checked the live data again - no codes - but I noticed that the throttle position never goes below 5%. As a comparison I also checked my 2.6 and that does go down to 0%.





Ignore the battery voltages - I didn't start either engine, the 3.2 is still recovering since I fixed the battery terminal and the self levelling air compressor was running on the 2.6

Possible that someone previous has adjusted base throttle settings to mask another problem which is why the throttle pot won't zero

Could always swap the throttle bodies to test the theory ;)

Feeling a bit silly now - squinting at the screen on my phone I hadn't noticed that I had mixed up the pedal position and the throttle position

I think I will need to start with a breather and throttle body clean.........

I suspect you might be on to something there.

When SWMBO bought a Golf a few years ago we couldn't work out why the idle was so fast. After some simple fault finding I discovered a faulty coolant temperature sensor. I changed that (and starting improved) but the idle was still far too fast. I eventually stripped the throttle body and found a piece of wood glued inside the gearbox to hold the throttle open....

I will give it a clean first to see if crud is holding it open.

I could..... but the Elite has been good as gold and I don't want to disable it by robbing parts off it.

Having driven the 3.2 MV6 to work a couple of days a week for the last few weeks the average fuel consumption is reading 21mpg. On the same journey my 2.6 averages 26mpg. I can't really say that the 3.2 feels that much more powerful than the 2.6 but it is definitely noisier and less refined ::)

New MOT issued for the project MV6 today :y

A few advisories for rust on brake pipes, front wishbone bushes and rear donut bushes.

I really need to make time to give this car some TLC....

Just took a couple of pics of mine.

Load cover in situ


Load cover removed but held in retainer.


Load cover locking tab for easy removal. The red tab was on the earlier load cover, not on the facelift, my mistake.

Pretty sure i have a pair of these still in the side trims i stripped out of mv6. What year is yours these came out of a 1998 t plate and look the same shape as the photo ones. I never got round to listing them lol like other parts of the estate and now im stripping my saloon which is killing me but gotta do what you gotta do.
