Exhaust line for cylinders 4-6 developed crack immediately before catalytic converter. Problem has occurred in other Touaregs, there is even a recall for 2014 models. Crack allows exhaust to leak nearby air intake to cabin. Noticeable exhaust smell inside cabin, especially when stopped. No warning, just check engine light after the crack. Crack along thin weld, leading right into the catalytic converter. Also environmental concern that exhaust gasses are not being treated. Potential fire hazard.

After recently purchasing this vehicle I noticed the car be long more and more sluggish. While driving one morning I experienced loss in power and an flashing check engine light and glow plug light on the dash. The car went into “limp” mode and I could not accelerate past 40 MPG on a busy road. I pulled over slowly and let the car sit. After turning the car on off and back on, the CEL went away . I attempted to pull out into traffic and with my foot to the floor, the car has no acceleration leaving me going extremely slow into traffic. The cars acceleration has been terrible and really not safe to drive. I have several CEL codes including P0402. After having the car inspected we found that the intake filter had Completely deteriorated at the bottom. Almost as if water had been sitting in the bottom of the air filter box. After removing the old filter and replacing it with a new one, we also cleaned the mass airflow sensor, unplugged it and plugged it back in. This did help the vehicle drive much better. Unfortunately, this only lasted for a very short time. Within several miles later I’m driving a vehicle acceleration issues persisted again. Some fluid was found to be inside of the oil as well. The car vehicle Is now scheduled to go back to have a full examination in service. Based on some recent finds it also seems that there have been many others who have experienced the same issue. Reference the lawsuit in China. https://www.caixinglobal.com/2018-03-16/volkswagen-apologizes-for-engine-defect-101222386.html

Water intrusion in air filter causing multiple malfunctions and severe loss of power. Multiple warning lights including, diesel particulate filter, glow plug flashing, and check engine. Vehicle had to be towed to dealer. Dealer replaced air filter and mass airflow sensor and charged $500+ for the repair. This is a vw cpo and still under warranty. They stated I must have driven through deep water for this to happen, which I did not. It would have required my driving through 3-4 feet of water. This never happened. This is the second time I have had the mass airflow sensor replaced in a 6 month period. I have noticed multiple complaints regarding this exact issue and also that vw has recalled this vehicle in china for the same issue but not the USA. I have contacted vw and they will not do anything.

The catalytic converter completely separated from its own flange where it connects to the exhaust header. Ultimately causing an exhaust leak and a check engine light. This occurred while driving and under normal operating conditions. Driving on a local highway with a speed limit of 55 MPH, which does not have excessive amount of pot holes) .

Engine light came on after driving three miles in dry weather. After seeing recalls in china about water entering the air filter box and saw that the bottom .25% was soaked. Saw many other touareg owners on forums with same problem. Dealer towed vehicle in and falsely claimed car was sitting in water. Reset the engine code and charged me $50+ for a new air filter and delivered the car back to me, with the engine light still on. I've called the service manager and waiting on a call back.

When driving the check engine light came on. At the service center at the dealer, the dealer indicated that the air filter had become wet with water. While reading a vw forum I became aware of a known problem with the air filter housing drain becoming clogged and the air filter becoming wet and water being ingested into the engine, hydrolocking the engine and requiring the installation of a new engine. The service only required replacement of the maf sensor. Even though my vehicle has only been owned for less than 8 months is under warranty, I have to pay for repairs (~$650). I am now hesitant to drive the vehicle at all. As this has been a known problem for a number of years with this vehicle I am surprised that there is no recall in place.

High pressure fuel pump failed causing our vehicle to stall with no power in the middle of a very busy off ramp from the highway. I had my son, wife and dog in the car. I could not move the 5000lb vehicle off the road, so I removed my family to side of the road while directed traffic. Vw dealer then came for us while I waited for the tow truck. Very dangerous. Now at dealer and vw is claiming many many very expensive issues with it due to this failure that they will not pay for, we were 837 miles from our home. Had to stay 2 nights in a hotel and rent a car to drive home. They still cannot fix our car. It's currently still at the dealer with no clue to what is wrong. There was no check engine light or any other sign of something wrong with the vehicle prior to the stall. It just lost power and died. I could not restart it.

Since the tdi fix I have experienced two incidents of power loss and then the activation of the check engine light. The 1st incident occurred in my driveway at a slow speed. The loss of power was for a short period of time. Vw called it a glitch not related to the tdi fix, and reset the check engine light. The 2nd incident occurred 33 days later on a surface street. I was in traffic at 40 MPH and the car had a rapid drop in speed. I pushed the accelerator to the floor which resulted in a slow acceleration. Full power restored in about a mile of "limp it" to work driving. Later the same day the issue returned and the dpf light came on and made the car undriveable. I feel the tdi fix has made my car unsafe to drive. Since the fix I've had 3 check engine light warnings in 10 months. I'm thankful my recent power loss did not occur on the freeway. Its a tragedy waiting to happen. My car is currently in the shop awaiting repairs.
