Many failures 
Solved
1993 Volkswagen Golf 200000 miles
Hello, I hope someone can help me with the many failures I've had and am still having with my Golf 93 gsl. It jerks as if it were about to break down and does not have much power; even though I might accelerate all out, it does not advance as it should. Even more, too many explotions can be heard, as if the fuel was about to be totally consumed or something similar. It also takes too long to start and even sometimes the battery unloads completely because of the many attempts to start the engine. Occasionally, the engine does not even start running, as if the battery was depleted. But, when direct current is provided with some wires, it does start and I can drive my car without inconvenients. What might the failure be? I really need your help.

Best answer (according to sophia)
Hi, it can be that there is some current leakage due to a short circuit, and that is why the battery unloads. You can as well check that the coil and ignition module are between the correct ranges and, in case you need to replace any of these, buy a Bosch. Check the MAF sensor and verify if there is some damaged wire. Check that the alternator is charging properly, and that the wires going from the spark plugs to the distributor are well connected. Hope I can help you find the solution to your problem and, if you do, please tell us how you did it. Good luck.
Hello, Vannie, first of all thank you very much for the time you spent reading and commenting. Apparently, the MAF sensor is not useful any longer so I am about to buy a new one, as it is not cheap at all. And talking about the short circuit, it was not this, but some worn contacts in the ignition switch. This was the reason why there was not the necessary electrical current to feed the battery and thus it sometimes started and others didn't. So now, I just have to buy this sensor I mentioned and change a spark plugs wire that is useless. Once I've bought the sensor, I would let you know what happened. Thank you very much.
CommentSurging whilst accelerating

My car surges almost like a misfire when accelerating. Coil replaced, Plug wires replaced, Plugs replaced, rotor replaced.

Fuel injector. I had same issue. These engines have big high cost problematic injectors
CommentFan not turning
2005 Volkswagen Golf FSI 2.0 130000 miles
Fan not turning, only turns when I remove the sensor that is connected on the radiator.
- I changed the thermostat
- traced the wires connected to thermostat sensor to computer box (works just fine)

Hi everyone, the fuel pressure sensor on a 2006 Golf 5 2.0 TDI has two terminals. Which terminal should I connect the 5-volt power supply wire to?

Fuse box problem
1996 Volkswagen Golf Gl 10000 miles
We were moving the fuse box back to its original location (just hanging in the wiring before) and we heard a spark sound. And now the car barley starts and when it dose it backfires and idles very badly the central lock stopped working and also all the instruments move down a bit when u turn on the incognito. Just wondering if someone has hade the same problem and know where to start (no fuses have gone out)

When the battery terminal is disconnected, the car turns off.
2004 Volkswagen Golf 2.0 40000 miles
When I disconnect the battery terminal, the car turns off every day for some time, approximately hours, as the car runs on battery power only. When I disconnect one of the battery terminals, the engine is cleaned immediately. When I move the positive terminal wire of the car with the green fuse box and I start it and disconnect the battery again, the problem goes away for a short period and then returns on its own after four to five hours, or usually in the morning.
