2008 Volkswagen Eos: sudden loss of power

Filed Sep 7, 2009 · Engine · 9,667 miles · WA

The 2008 volkswagen eos' engine suddenly lost power on an interstate highway and luckily, we were able to guide it to the side for safety. We turned the car engine completely off and let it rest for several minutes. It started and we got back on the road and drove directly to a vw service that was closest to us. They saw "faults" of being low on fuel and stated we should fill the fuel tank before it gets to the reserve amount. It has not stopped since we implemented this intervention. However there was an earlier problem with losing the power while driving at freeway speeds that we did not report as it seemed to correct itself within about 60 seconds while driving. Concerns are raised on 2 counts: 1. Is it really about fuel level, when no other car I have ever owned has completely stopped when low on fuel (not empty, low) and, 2. This seems to be a complaint that has been experienced by others before. This makes us concerned about the operation of the vehicle, safety and the risk of accidents.

2008 vw eos dsg automatic transmission has same issues as reported by other drivers on newer models. The biggest safety hazard are delays in shifting gears crucial for lane changing and passing. At worst vehicle seems to run out of steam or not be 100 percent there. I have owned another vw with dsg and those symptoms were never present. The problems are on and off. Car has never stalled but most of the incidents involved delayed shift and loss of power.

I purchased a 2008 vw eos lux 2.0t with dsg transmission in september 2007. Almost from the time of purchase I experienced antic behavior from the transmission which I initially dismissed because I knew it was a new kind of transmission that I wasn't used to. My problems consisted of surging, rough shifts and a complete loss of power when attempting from a dead stop. This latter condition was the most dangerous as I would be putting my foot down for power (for instance, accelerating into fast moving traffic) and the power would just disappear completely and the car would hedge and balk. My vw dealer has seen my car 5-6 times now for repeated transmission issues. They replaced a mechatronics unit in february 2008. Then they replaced the dual clutch packs later that year. This year they replaced the mechatronics unit again when they determined that the first replacement unit was from a manufacturing run of units that were known to be faulty. I'd say that after this recent fix the transmission is about 95% of normal. I still experience awkward shifts from time to time. It is worth noting that these persistent problems were extremely difficult to diagnose because they were often intermittent and there were no computer fault codes recorded by the car's diagnostics. It was only through the patience and persistence of the service department at my vw dealer that the problems were eventually diagnosed and remedied. As it happened, the most dangerous condition (the dramatic momentary loss of power when accelerating hard) was determined to not be a result of the transmission but from a faulty brake switch. This switch is responsible for protecting the transmission by not allowing the transmission to be revved too high when the brakes were still on. The switch on my car was delayed in telling the computer on my car that I had taken my foot off the brake and wanted power. The switch was replaced and the hedging/loss of power from a dead stop went away.

2008 vw eos lux. When new, the vehicle was great, and then we experienced what felt like running over a speed bump when accelerating from a stop; at around 25-30 MPH, the shift is very harsh and the car seems to momentarily lose power. The dealer "reflashed" the car, which seem to solve the problem, but it came back. They then replaced the mechatronics unit, but the problem persists. When pulling onto a busy street this problem is an accident waiting to happen.

Dsg transmission in 2008 vw eos began lurching/hesitating and dropping into neutral at 12,000 mi. By 15,000 mi. Car couldn't be driven in bumper to bumper traffic without bucking like a bronco. Several times when merging at highway speeds, car would lose complete power as the trans shifted to neutral without warning. Backing up, especially with any incline, was another lurching affair, much like a new driver attempting to drive a manual trans for the first time. Taking of from a stoplight was hit or miss. Car would lurch and hesitate, causing drivers behind me to slam on brakes as I lost power. Very dangerous and uneasy feeling. Vw dealer determined problem was caused by a failed mechatronics unit in the dsg. Was replaced under warranty at approx. 16,000 miles. Old part was not made available.
