Question about 2004 Volkswagen Passat

Open Question

2004 VW passat glx will not communicate with obd2 scanner...checked fuses and found a wire attached to. one of 2 fuses I had to replace ...one was for the obd2 and the one right beside it....the wire ran to the dash area on drivers side , but I never saw what it was hooked to. My friend said his old mechanic removed the wire before he looked ...what could the wire have been meant to do? And how do I diagnose the obd2 port issue? I was trying to scan because my friend replaced the oil pump after an overheating issue. He said it started up and idled fine, so he left it idling to charge the battery. The next morning it would not start again....any suggestions? Thanks in advance for any guidance you can offer!

SOURCE: 1992 VW Polo 1.3L Coupe: warning light mystery

Polo Coupe 1043,1992, Will not start, can be bumped started, sometimes!!, theres a strange clicking noise from under the air box, when the ignition is on and sometimes the oil pressure light comes on when the car gets upto temperature, then I lose all power and then the engine cuts out. I've recently changed the dizzy cap, rotor arm and battery, all the leads are new ish along with the spark plugs. The previous owner has changed the head and done all that, leaving much of the engine loom unlagged and bare. Could this cause a problem on some of the electrical systems?

If everything is turning on, and there's power... check for 12V at the alternator. it may be out now.... or a connector came loose, or wire broke.

Shaking engine, weak power, blinking check engine light


You have a bad coil pack, they usually crack from age and heat. It's best to replace them all. Check for a VW recall on this item.

2002 VW Passat GLX AWD, stereo stopped working


HI,
Passats can be reset if the radio is pulled out and the fuse on the back is removed. Wait for 2 mins, reinsert the fuse and turn the radio on. If this doesn't work, please take it to the dealer for the unlocking of the code, for which he may charge you some fee.

Do let me know if it was helpful.

Regards
Kanu

VW PASSAT 2004 CD PLAYER ERROR 1


This happened to my 2004 as well just last month. It kept spitting the CD out and giving me the error message. I took it into the dealership and since it was under warranty still, they just replaced the whole radio system.
