E34 problems

Having a few issues withe the car and don't really want to get rid as it's never let me down until now. It's a 94 525 tds 220k on the clock. To which I've put 50k on.

The problems are:

Slight hunting at idle.
Below around quarter of a tank it's difficult to start. So I leave full (had this problem since I got it)
Started with Lack of power I can rev fully through first gear slowly and next to nothing in second or third.
Tried the stomp test and injector light flashes codes 8, 18, 29

Since owning it for 2 years it's had a good few services, just changed fuel filter and air filter again in case. New rear fuel pump (in tank) and new glow plugs. I have blanked off egr with a 2p and blocked the vac pipe. I did have a chip box on but have removed in case that was the problem but to no avail.

One of your problems could be the fuel sending unit, its linked after the fuel pump. Its a real common issue on the e36's. Also it wouldnt hurt to get your fuel pump checked out again even though its new it can still go bad shortly after changing it. One other thing that could be your starting issue, try getting a new fuel pressure regulator, its typical for these to go out on any car.
If it ain't broke, FIX IT!!
