yes if you read that link it will explain(self inflicted by cheap ebay test kit).
in your video it doesnt look too bad, as you accelerate then back off the values all drop pretty low, then number 3 creeps up and 2 and 4 try to balance it out, if you add all the +'s and the -'s you should be around 0. if it was 2 or 4 surely it would adjust number 1 to try to balance more, least thats how i see it.
id forget about it for now, bung some injector cleaner in now, top up your tank and then check again on thursday when your home.
 
Hey no new information yet...
After a few "spirited" drives values settled like this:

I bought 1L of a diesel additive that all Bosch service mechanics recommend and I'm waiting for the fuel in the tank to run out so I can put the additive in and go for some redline drives (the concentration of the additive in the fuels tank must be as high as possible which means no more than 10-15L of diesel).
After I do that cycle I'll fill up and empty another tank to completely use the remaining additive and then I'll check the values again (and report).
 
These are todays values after adding additive to 15L of diesel and driving like there's no tomorow... I think I'll start using this additive more regularly now :)

Bringing an old thread back to life... So after the values in my last post, they went back up where they were before. The additive was a temporary answer obviously and I didn't bother to buy it any more after that.

Today I'm looking at something else and I check these values just by the way. I was astonished:

I didn't add any additives or anything of the sort this time. The only thing that changed was that the swirl flaps were removed and the holes plugged (and the cambelt/WP/v-belt was changed).

The only logical reason for this change that I can think of is the intake manifold...?

Any thoughts?
