SAAB 95l 2004 auto 2ltr petrol turbo keeps completely draining battery, WHY????


Check that altinator belt is tight enough, it should be able to move 1/2" up and down on the side with greatest distance between pulleys, if the belt is tight enough the alternator may be damaged or faulty. Hope this helps

How to fix 18033/P1625 powertrain data bus?


Told you already. The data bus goes between all the computers in the vehicle. All of them. Do Not apply 12 volt power to them.

How to fix 17887/P1479 brake boost vacuum and 18033/P1625 powertrain data bus?


I would go to the data bus first. No easy fix for this. You need a scanner( not a code reader) to trace this down. You also need wiring schematics and pin outs for the plugs. And a volt/ohm meter. after that issue is fixed. If you still have the booster problem, replace the vacuum pump.

I have a 1998 audi a4. it will not start and gives me the p1749 and p1625 codes. how do i fix this?


code p 1625 refers to CAN databus, TCM--incorrect signal===causes --TCM trouble code/s stored---TCM incorrectly coded---wiring---matching resistor in ECM
I don't have a listing for code p 1749 but codes 1748 and 1750 are concerned with TCM defective and voltage supply low
so after you check the wiring and connections form the transmission you have 2 options
use a known good ECM to replace yours ( will eliminate any ECM faults)
and/or replace the TCM module on the transmission

Gm code p1625


connect amp meter to battery, by removing battery terminal and put one test probe of meter on battery terminal and the other on battery terminal. with vehicle turned off anything higher than approx. 25 mA, 0.025Amps is high. depending on vehicle electronics. start removing fuses one at a time to find concerned circuit that is drawing high current. then find out what else is on circuit and disconnect one at a time with the fuse back in modules, motors, radios, etc... or what ever the fuse supplys power to until you find the culprit.

P1625


Code 1625 is for a problem with the radiator fan relay.
The relay could be faulty, or the radiator fan may not be functional.
The components and circuits would need to be checked out.

There is a diagnostic code P1625 for 2001 Saab 9-3 convertible with 88,115 miles. Is this an expensive fix?


P1625 means that the engine computer has lost communication with the antilock brake and/or traction control computer for at least 3 seconds. How expensive this is depends on why it has lost communication, It could be something as simple as a loose connection at a wiring connector or a broken or shorted wire in the PCI bus circuit inside the wiring harness. (Which may require considerable diagnostic time to find) or it could be an internally failed ABS module.

Recommendation:
If you are NOT experiencing ANY of the symptoms below, I would simply clear the code and move on.... It is an intermittent fault that you will most likely not find very easily. If you ARE experiencing ONE OR MORE of these symptoms, then the problem needs to be diagnosed by checking the ABS module's ability to communicate with a scanner while testing the PCI Bus circuits.

Other possible symptoms of Diagnostic Trouble Code (DTC) P1625
• Speedometer malfunctioning
• Traction Control malfunctioning
• Antilock Brake System malfunctioning or ABS light on
• Cruise Control malfunctioning
