The air bag light has come on in my 2004 Octavia 2 1.9 TDI, not sure why it came on in the first place, I have looked and googled all sorts. I took the two seats out and checked the connections (two connectors per seat) and they are fine, took them apart and clicked back together many times to try to clean up any contacts just in case. I checked the passenger and driver wiring into the doors (in the convoluted rubber bits) and again all fine, no breaks, chaffing etc. I have a cheap OBD11 reader cable and a VCDS lite on a laptop, however it does not show the Octavia 2 only the Octavia 1 in the chassis identification but having said that I have ran diagnostic's on it before for the engine and it shows up why the EML light has been on for years (two glow plugs need replacing and the anti-shudder valve is faulty, luckily stuck in the open position so it all still runs well). So when I run the diagnostic's it states it can't connect to the air bag controller or something similar and obviously does not show what the fault is and again obviously can't reset the light. Does anyone know for sure if I buy a later version of VCDS and possibly a new cable will it work to show me what is at fault and if it only needs a reset will VCDS lite actually reset an air bag issue. Basically the car runs fine and returns great miles per gallon but will soon require an MOT and I know it will need driveshaft boots, shockabsorbers and a few bushes doing but I don't want to spend out loads on parts and my time fitting them if the air bag light won't go off. I'm good with mechanical items on most vehicles but too old and long in the tooth when it comes to electronic's. Taking it to a dealer is a no no, the car will just get scrapped if I can't do it myself. Thanks in advance for any help or advice.
