2005 Volkswagen Touareg Problems

What owners report

Owners of the 2005 Touareg most often describe fuel leaks and strong gasoline smells traced to a cracked fuel filter flange or housing on top of the tank, frequently at higher mileage. Electrical complaints are the next most common group, typically aged wiring and water intrusion affecting headlights, floor connectors and the OBD port, while transmission and driveline noises and airbag warning lights also recur across the sample.

1. 1
   Fuel system

   Cracked fuel filter flange / fuel smell and leak

   • 15 complaints (20%)
   • median 102,000 mi at 12.5 yrs old (9 state mileage, few)
   • filed 2012–2023

   Owners describe a strong gasoline odor around the vehicle, especially after refueling or while parked, and sometimes find fuel pooled on the garage floor or dripping between the rear wheels onto the exhaust. Several traced it to small cracks in the plastic fuel filter flange or housing under the rear seat and had the part replaced. Complaints also describe the vehicle running out of fuel almost immediately after filling up, or stalling and failing to restart after refueling. Mostly reported between roughly 50,000 and 140,000 miles, often noticed while parked or shortly after refueling.

   Recall 17V5830001 related service bulletin

   What to check: Ask whether the fuel filter flange recall work was done and for receipts; on a cold start, smell around the rear wheel arches and look for stains or drips on top of the tank under the rear seat access ports.

   “Gasoline leaking from the tank runs over the right-side exhaust tubes to the ground. The flow of the fuel leakage is very high at a drop-rate of more than one drop per second with the vehicle parked and the engine running at idle speed. Once the engine is turned off the leakage stops within short time. I got aware of the defect due to the strong gasoline smell after stopping and getting off the vehicle. I investigated and saw gasoline dropping to the ground between the rear wheels. …”

   NHTSA complaint #11047622, filed 2017-11, 100,000 miles

   “Gas leak (see pics). I started noticing a strong gasoline smell and my car keeps running out of gas almost immediately after filling up. This has not been inspected nor confirmed by a dealer. This is my only source of transportation and needs to be fixed ASAP. There is not a VW dealership where I live, the closest being in Mario, IL, or St. Louis, MO.”

   Air bags

   Airbag warning light on / wiring and connector faults

   • 7 complaints (9%)
   • median 30,000 mi at 2.8 yrs old (7 state mileage, few)
   • filed 2006–2019

   Owners report the airbag or passenger airbag indicator staying lit, which complaints interpret as the airbags not deploying in a crash. Dealers typically ran diagnostics, reset the module or quoted replacement of an airbag wiring harness or igniter; in several cases the light returned within months or after repeated visits. One owner described a fault code for the front passenger airbag igniter and was quoted a harness replacement. Appears from very low mileage up to about 110,000 miles, often recurring after a reset.

   1 related service bulletin

   What to check: Turn the key to ignition and confirm the airbag light goes out after the self-check; ask whether the airbag harness or connectors under the seats have been repaired.

   “I am the owner of a 2005 vw Touareg which recently had the air bag warning light come on and stay on. I took the Touareg to a Volkswagen dealer where I was charged $104.48 for a diagnostic test. The diagnostic test provided the stored fault code of 01218, front side passenger airbag ignitor upper limit exceeded, thus recommending replacement of the airbag wiring harness for $320.00 estimate. …”

   NHTSA complaint #10759641, filed 2015-08, 104,098 miles

   “The drivers side airbag will only work for 2 months at any given time then stops working. I purchased this vehicle new. Every couple of months the censor that indicates that the airbag is not working comes on. I take the vehicle in to the dealer, they reset the censor, they tell me my airbag is fixed, insisting that this time they have identified and corrected the problem. And 2 months later the censor is on again indicating the airbag is not working. …”

   Electrical system

   Water leaking into the driver-side floor and electrical

   • 9 complaints (12%)
   • median 52,000 mi at 7.0 yrs old (7 state mileage, few)
   • filed 2007–2026

   Owners describe water pooling on the front driver-side floorboard after rain, blamed on sunroof or windshield leaks or clogged air-conditioning drains, which then soaks the wiring under the carpet. Independently, owners report intermittent check engine and warning lights, an OBD port that will not communicate with scan tools, and random electrical faults that some dealers could not reproduce. Complaints also mention modules and harnesses replaced at the owner's cost. Reported from low mileage up to around 140,000 miles, often after rain or on vehicles parked outside.

   3 related service bulletins

   What to check: Lift the driver-side floor mats and check the carpet and wiring for dampness, staining or corrosion after rain, and ask whether the sunroof drains have been cleaned; have a scan tool confirm all modules communicate.

   2 excerpts from owner complaints in NHTSA records

   “Due to a leak in either the sunroof or the windshield water continuously drips down every time it rains onto the floorboard of the driver side of this vehicle, creating a sopping wet floor board that has 2 inches of water, which in turn soaks the whole electrical system for this vehicle. I mean the water continuously drips from the time you purchase this vehicle until forever I guarantee that anybody who has a v8 version of the 2005 Volkswagen Touareg has a sopping wet driver, side floor board! …”

   NHTSA complaint #11541808, filed 2023-08

   “My OBD port cannot be read. It will not communicate, or I cannot communicate with the vehicle using any OBD reading software. Myself or my mechanic. This is a major safety concern due to several reasons. Most importantly, I'm being told that it can affect, or it's probably caused by, electrical problems that are well known on this particular model and year for this maker. Something's wrong with it, where it's either being shorted somewhere, or for whatever reason, because it's not communicating. …”

   Electrical system

   Headlights cutting out / brittle wiring in headlight units

   • 5 complaints (7%)
   • median 41,000 mi at 3.9 yrs old (4 state mileage, few)
   • filed 2006–2023

   Complaints describe headlights switching off for several seconds and coming back on, sometimes only one side, and in some cases both low beams failing entirely. Owners who opened the headlight assemblies found cracked, brittle or missing insulation on the internal wiring, which they attribute to short circuits; bumps in the road and nighttime highway driving are mentioned as when it happens. Repairs involved reworking or replacing the affected wiring or headlight units. Reported from about 10,000 miles up to roughly 110,000 miles, usually as an intermittent fault.

   What to check: Check both low and high beams and inspect the wiring visible inside each headlight housing for cracked or exposed insulation; watch for flickering over bumps on a night test drive.

   2 excerpts from owner complaints in NHTSA records

   “After doing major research with other owners of like year and model I have discovered that i'm not the only one that is experiencing headlight electronics or headlight electrical system within the headlight assembly frying the electrical wires, cracking the brittle wire coating and exposing many of the electrical wires together within the housing unit of the headlight Assembly. This caused many short circuits Headlights Shutting off at random times but most importantly shutting off at night on a dark highway. …”

   NHTSA complaint #11508252, filed 2023-02

   “Both left and right headlights failed and would not operate in low beam mode. Upon inspection, I noted that the insulation for the wiring inside each headlight unit was brittle, cracked and in some cases the insulation had fallen completely off. This caused both headlights to ground out and fail, potentially hazardous during vehicle operation and a potential fire hazard.”

   Fuel system

   Fuel pump / stalling or no-restart after refueling

   • 10 complaints (13%)
   • median 70,000 mi at 5.9 yrs old (7 state mileage, few)
   • filed 2007–2026

   Complaints describe the engine shutting off within seconds of starting, a loss of power while driving, or a vehicle that will not restart after being refueled; the battery and warning lights may stay on while the engine dies. Some owners were told by an independent mechanic that the fuel pump had failed, and a few mention the pump was replaced but the symptom returned. Others found the fuel supply line separated at its crimped fitting near the engine. Reported from near-new to about 130,000 miles, several cases tied directly to refueling.

   Recall 17V583000

   What to check: On a test drive, refuel and confirm the engine restarts promptly and idles steadily; request service records for fuel pump or fuel line work.

   “I took my SUV to the dealership for a fuel pump recall, about 3,000 miles after my SUV is causing problems like start but turn off within 40 seconds. I took it to a local mechanic for diagnosis and he says is the fuel pump. I contacted the dealership but they are kind of unresponsive...no advisors available, no returned calls (Volkswagen south coast santa ana ca).”

   NHTSA complaint #11255351, filed 2019-09, 25 miles

   “Fuel supply line separated at a connection between hose and fitting that is secured by a pressure crimp. Location is directly adjacent to and above engine block. My engine was cool enough that a fire was not started, but had the engine been hot it certainly would have been disastrous.”

Buying note. A pre-purchase inspection that includes a scan-tool check of all modules, a look at the fuel tank area for leaks or fuel smell, and the driver-side carpet for water damage is worthwhile on this model year. Ask for records showing whether the fuel flange recall and any airbag or headlight wiring repairs were completed.
