Ongoing engine misfire issues. after 3 visits to dealership and replacement of coils, fuses, relays, etc, root cause determined to be a short between the after run coolant pump which causes a voltage draw and confuses the ecm. after talking with vw technician, i learned that this same exact part on audi vehicles is under a safety recall for the shorting issue that my pump is having because the short can cause fires. however, the vw part is not under recall. my family could have been put in grave danger because this part is in my car and has not been recalled. in addition, even though the part has failed, vw will not compensate me for the repair, so i have no choice but to pay $500 out of pocket to fix a safety hazard in my vehicle. for reference, audi recall number is 18v229000.
While driving at night i had several lights quit working simultaneously. a bulb warning light illuminated on the dash and messages for right front low beam, right front turn signal, left rear turn signal,left rear brake, right front high beam, right front fog light, left front side, right rear side, and license plate bulbs all appeared in the information screen. i checked outside the car and all of the lights that i got messages about were inoperative. as there was no chance that all of these bulbs failed simultaneously, i did some research to determine what might have caused this. numerous internet searches for these symptoms seemed to indicate that a fuse in the under hood fuse panel could be to blame for this. i checked the f16 fuse and found it burned on one side of the fuse. the fuse panel was also slightly melted where this half of the fuse was inserted. pictures are attached. my local vw dealer said the fuse panel will need to be replaced. upon doing some research, there is a safety recall on the 09-11 tiguan (code: 97z9) and a service action on the 09-10 jetta and 09 gti (code: 97am) for the exact same issue i am experiencing. both the dealer and vw usa say that i am 100% responsible for the cost because my model and vin aren't covered under any campaigns.
'takata recall' on the horn, it stopped working, checked the horn, and fuses and wasnt that. 'takata recall' on the front lights, checked the bulbs and it wasnt that, most likely is the wiring
The fuse box melted. this was caused by a terminal or a fuse over heating. this caused an outage for all the right-side lamps of the vehicle and some lamps on the left-side. the lamp error was reported by the vehicles multifunction display. the car was running fine in the morning and experienced this failure after starting up the vehicle at noon. i restarted the vehicle over and over trying to clear the error. the bulbs in question appeared to be fine. i drove the vehicle straight over to the vw dealership for service. later, the dealership confirmed the fuse box had melted after i researched and discovered similar occurrences with other vw models. the cost of repair was $377.
