Beisan Systems VANOS overhaul at Redish

Hi James,
Thanks for the pictures, great to see, and a testament to your hard work as usual.
I've not really driven the M over the last month, having a bit of a hibernation in the chilly weather, so I can't give a comprehensive review of the work done.
However, I can say that the work done by Redish is of the higest quality, as you can see by James's post above. Very happy with the work done as always, it took the best part of 2 days work in the garage....so got a bit of a bargain price wise! No issues at all with the work done.
So, the hesitation/idle dip issue I had previously, is still present unfortunately. The VANOS readings in INPA for the inlet side are the same as before, as in well out of spec. I think it's fair to stress, that this is nothing to do with the work Redish has done, clearly there is still a problem somewhere along the line which is causing the VANOS on the inlet side to retard massively, which in turn is no doubt the root of my idle/hesitation issues.
Knowing that the VANOS has been apart and professionally rebuilt and put back together, along with the timing, rules out a problem in this area in my eyes. Which obviously is useful, as well as future proofing that area of the car. Frustrating that it didn't fix it, I know it's going to be something small and stupid causing all this.
Anyhow, for that reason I don't feel it fair to give a review of the Beisan product as such, although I instantly could tell it was quieter and less rattely.
I will be in contact with James regarding further diagnosis of this issue, hopefully he's up for taking on the work! Logically in my eyes, it has to be a sensor or something similar sending a bad reading to the inlet side of the VANOS, the exhaust side of the VANOS is fine, the set point as it should be, just the inlet side is off.
I know one sensor that is specific to the inlet side and also sends a signal to the VANOS, is the intake cam position sensor. It's not throwing an error code, but then neither is anything else, and something is clearly amiss. I guess if the signal is 'bad' from this sensor, the VANOS doesn't know where to set itself so goes into a 'safety' mode and retards as much as possible. It's a stab in the dark as usual, but logically it's an option, and not too expensive to replace, so will be my next port of call!
Sorry there's no review as such on the actual Beisan product, but anyone thinking of doing this, or just having work done in general, would be foolish to overlook Redish, you can see the care that goes into the work detailed above, so as always comes highly recommended from me!

Only just spotted this, but that is absolutely excellent work. As above when the time comes i cannot imagine going anywhere else to get this work completed.
Thought I'd give this a quick bump to see if you've noticed any change in the car with a bit more time or if you've got any further with diagnosing it.
Just a thought, but after looking at the file beedub posted regarding the s54, I wondered if perhaps the vanos isn't seeing the correct oil pressure to function correctly. Would tie in with what is shown in the images above-Do you know if the oil pressure has been tested?
