Selespeed oil

Are you overfilling the tank? There is a dipstick on the lid. You must not overfill it. To fill, open drivers door, turn ign switch to MAR and wait for pump to stop. Then carefully add oil to mark on the dipstick. Since you are losing oil, it will probably overflow the oil until the level is OK, so you probably do not need to add any more oil.

In that case there is a possibility that you need to maybe have the system bled. That is a service agent's job using the Examiner software tool. Also, the accumulator could be faulty, which means a new one, and that starts to cost. Fiat sell the accumulators separately for their similar system, but Alfa only sell the complete robotic assembly!

Does the gear change work OK when you drive the car? When you open the door first thing the pump should run for maybe 11 - 12 seconds or so to charge up the accumulator before you start the engine.

seles often do this, some owners (including me having read about it on here) fit a small catch tank, typically a small pop or vitamin bottle at the end of the breather pipe and strap it to the chassis. If you do that make sure you put an additional hole in the top to allow the system to vent.

ok , but does this solution will fix the problem ?
i think that the selespeed will keep loosing the oil and it may start doing problems with gear engage !
can you tell me more about this solution?!

check the forum for a picture of my catch tank, oil that is thrown out in the catch tank , is sucked back when you open the door. No spillage and no topping up ever !!

see thread: which oil for Selespeed

I fitted it some 4 years ago, mainly because checking the level is a bit of a pain (greasy fingers and all that), now my check is to open the car at the
passengers side and open the bonnet to see how much oil is in the catch tank
then I open the drivers door and see the oil being sucked into the system.

I also fitted a catch tank but no oil goes into it at all. The oil level is where it should be in the resevoir and everything is working fine. I do not think a properly working selespeed with correct oil level should overflow either into a catch tank or onto the ground. Have you tried having the system re-calibrated by a dealer?

alex i think you are right , the oil shouldn't over flow in correct working , but i went to the dealer they check it and they told me that in the examiner every thing is working fine and there is no faults ! and the pressure is between 45 and 55 bar so i still dont know whats wrong ?!
they said for try to replace the pump to check if this will fix the problem , but it cost a lot and if they repalce it and didn't fix the problem they cann't have it back it's mean i cann't return it to them !
if you were in my shoes what you would do ?!

When the dealer checked the system, did he run the bleed mode as well? If there was some air trapped in the system it would expand when the car is turned off to push oil back into the resevoir. I am not certain about this, but it is worth asking him that question. It is certainly strange what your system is doing.

how can i get the air out from the system , can i do that at home ?!
i think its propably can be that air had trapped in the system because before 5 months i changed the selespeeed oil in the system , so how can i check if there is air trapped in the system , and how i can get it out ?

Bleeding the system is one of the procedures that can be done using the Examiner software. It needs the agent to do it, but some 156 and 147 owners use a software system called Alfadiag which can be bought on the web. It also needs a special connection cable and a PC as well. Probably best to get your agent to run the bleed first to see if that cures the problem. Did you check whether your agent did run a bleed?

I sell (and so does SEARS) the modified OBD2 cable, > 150 AO members have bought the cable
PM me for details and see AlfaDiag Alfa Romeo Diagnostic Software for more info

To be completely fare and open, it needs to be said that you don't need a "modified" cable to connect to the engine ECU or Selespeed ECU.

What DC says is too BUT if you have bought Alfadiag you will need a modified cable to communicate with the airbag system.

At present A/d does not communicate with ABS, see my siggy if oyu need software to do that.

back to selespeed issues:

the system will depressurise over night, thats why it primes itself when you open the drivers door so as its ready for use by the time you start the car.

if it is spitting out the fluid it could be that it is OVERFULL or that the accumulator is defective

Accumulator (Vessel): Part Number: 71751195

to check the oil level you need to open the bonnet, then allow the pump to prime/run & as soon as it stops running then chekc the oil level. if its above the max, use a syringe to remove excess fluid
