My car, 156 selespeed, was falling back in neutral from rear or first gear 15 days ago. Error light was on.
The Mechanic, found some error codes such as P0725, P1756 etc. A potentiometer has been replaced with a new one (marelli PF2C) and all error codes are gone. Plus, all electrical connections, sockets etc. cleaned. Pump pressure is 56 and seems working well. No error light on display.
But now car is worse than before because stuck in neutral, never engage other gears. BOSH diagnostic device found no error. All calibration is concluding well but still stuck in neutral position, never change others. I replaced battery new one, but no answer.
I tried to do everything adviced on the forum written before me for same problem but no positive result.
My mechanic is not experienced for Selespeed and there is no better option in my city. So i, myself search to fix the problem.
Can anyone please tell me what is missing for my Selespeed?
Thanks in advance.
