850 2.5 20V Automatic air conditioning

Hi, after poor performance I wanted to have the climate (2 zones automatic) replenished at ATU, which told me that the pressure was too high (which was right) then to the Bosch service which I did not have my vehicle in 8 weeks (part problems, delivery) my climate “repaired, it was (expansion valve, dryer, capacitor, as well as the line with valve from the capacitor and compressor renewed) but was taught by ATU the system completely and the errors went off (Kl ima does what she wants, mainly only slices or foot nozzles, which is still so now, but it is all possible new ) my question would be: does this climate have a kind of emergency run so that it does not unlock because the old faults are still in the system, or is now still the control part too. PS. Sorry C-: but is it normal that a 1995 850 20 V 9101 488 has a collection pot dumpster without flex tube “Fehderbolzen Verbund” was stolen to me at the beginning of the year the cat, therefore new exhaust system In the case of the 2.5 ern, this has been changed to flex tube due to problems with tightness in the MOPF and only the 10 V of the same system.
