Regardless. There is a large amount of speculation going on, with little action. Things will only get more confusing until some further data / testing is supplied.

Can I (test)run the car without the alda?

I know little is done. I will test "cleaning" the WG as I was advised first, only problem is finding time to do everything. Winter is knocking on the door, and I am in the middle of digging drainage around the house. I've spent all summer digging out half a metre of soil from the basement, and all winter and next summer will probably be spent converting the basement into usable rooms.

I am hoping someone will recognize the symptoms of my car, and maybe have some experience with the same problems. After all, this cars do grow on trees, and the mileage on mine isn't extraordinary high.
There must be a reason for the drop in boost pressure. As far as I can see, this must be because of :

1. Turbo not able to deliver enough air even if there is enough exhaust (turbo worn out?).
2. Too little diesel --> too little exhaust --> too little boost.
3. Diesel delivered too late, making the exhaust pressure drop, and therefor it is not enough pressure into the turbo.

I think this is the main reasons that can influence the boost pressure. Each reason may have different causes.
