Hey there, I'm afraid I've ran into some problems with my 156 selespeed...

Car: Alfa 156 2004 selespeed sportswagon

Problem: Selespeed pump is not starting up when the door is opened. Car starts normally and can be driven. Sele changes gears but drops to N every few seconds and selespeed warning light flashes with some beeping noises. The gear number flashes as well. I noticed some oil on the ground. It was on the drivers side (EU).

I tried to check the selespeed oil level and it seems to be below MIN. However, I'm not sure if the pump not starting on door opening has any effect to the oil level?

What could cause these problems? Failed pump? Actuator? Accumulator? I really have no idea. I will get an OBD cable and Multiecuscan but that'll take couple of days.

Any comments and tips are highly appreciated!

Most probably the accumulator is shot. Oil level should not be below MIN. However the level should only be checked after opening the driver's side door and turning the key to MAR but not starting.

I did the oil level check as you described, door open and key on MAR.

It sounds like the system is not holding pressure well. Get it on diagnostic and check the pressure.
Make sure that there are no visible leaks from the actuator itself, then either the accumulator is bad or the pump is faulty, or both.

Note that even if the pump is still working, it might not be in good condition. Normally I will run calibration routine on the system because it will require a lot of pumping during the routine to maintain the hydraulic pressure. If the pump is not in a good shape it might stop running halfway and the calibration will fail.

Update:

I have removed the battery and tried to loosen the accumulator, but I didn't manage to get it off. I tried to unscrew it with an adjustable wrench, but there doesn't seem to be enough space to get a good grip from the accumulator. One of the edges from the accumulator's bolt seem a bit round. I'm not sure if the accumulator is rusted. Any advice on how to get that thing removed? Would rust removal CRC and some heat help?

An adjustable spanner will be too thick (as you've found out).
You need a thin spanner, which usually means grinding one down to fit in the gap.

Aaaargh I'm going mad! I managed to replace the accumulator and the test drive went nicely. However, today after about 50 km of driving the exact same problem occurred: selespeed warning light flashing and the car won't change gear. After a few seconds, the problem disappears and selespeed works for a brief moment. Again, I noticed oil leaking on to the ground. I topped up the selespeed oil and the car drove fine, so that seems to be the reason. Any pointers? I'm getting really desperate!

You should check it on a diagnostic software to know the actual fault.
Make sure the reservoir is not overfilled. Then try to clean the exterior of the actuator and observe for any leaks.

The system needs pressure to operate. So it is essential to eliminate all leaks and the pump must be in good condition to have the capacity to generate the pressure required.
