Well, the wiring has been rectified. It had those terrible crimp type wire joiners and the wire had broken on one of them! It now has just a tad more airflow through the rad! We shall see if it will keep its cool. I am surprised that during the summer it managed on just one (and I mean barely!).

However, the wiring going to the fans could be better, but then it could be for the 5th Injector,chargecooler pump etc. I plan to make an accessory fuse box/relay board with one dedicated wire going towards it as opposed to the mess that is there at the moment. Once that is done I plan to rewire the lot to the fuse box. Besides looking alot tidier the wiring should also be spot on with the connections being a step up from what they are ; I have solder half of the connections for the timebeing, mainly the 5th Injector wiring.

I did try to screw out the idle speed adjustment but it seemed to have no effect. The next thing to check for is power at the AAV and to see whether the AAV is working or not.
