Electrical System Problems of Volkswagen Jetta Sportwagen - part 2

Coming back from the mall, I turned on my car and a few seconds later the engine shut down and "immoblizer active" message appeared. Restarted car again, engine shut down and the same message appeared again. I tried it a couple of times more and then called vw roadside assistance to get my car towed to my dealer, which luckily, is near by the mall I was at. Once at the dealer (got there at 4:30pm, and they close at 5 on saturdays), the technician had time to look at my car. He came back 15 minutes later and was surprised of what he found. The diagnostic machine could not read the engine control module. He said that pretty much according to the test, the ecm/ecu did not exist! I have had the car for about 8 months (brand new) and only aprox. 9500 miles driven so far. They will check the car in detail on the following Monday. Will wait for results.

2011 Volkswagen tdi wagon does not start with any original keys based on the message the “immobilizer activated�. I am afraid this system could shut down my car in bad situation for no reason. I think this should be investigated. I think based on my research many other owners complaining about this issue. Please investigate this.

With the speed control engaged and while pressing the deceleration switch on the turn signal arm to slow the vehicle down, the speed unexpectedly increases. Each press of the deceleration switch normally causes the speed to be reduced by 1 mile per hour. The first few presses cause the vehicle to decelerate as it should, but occasionally on the third or fourth press the speed jumps back up by 2 or 3 mile per hour. Sometimes it corrects itself and sometimes it keeps repeating the pattern.

New car manual transmission, car stalls out at low speeds on snow covered roads. Rpm's 1400 - 2000 can stop problem if traction control is disabled. I have driven manuals for over 30 years and it is not operator error it is a problem with the traction control and computer system - it dies in traffic and requires the key to be turned all the way off and then back on to get the car started. Taking the rpm's up to 2500 avoids the problem - but this will certainly wear out the clutch. Dealer feels it is just a sensitive clutch - I now have 600 miles on the car and have to disable traction control to stop the stalling at start ups and low speed shifting.

While driving on interstate, without warning or change of throttle, engine slowed noticeably. Unable to maintain highway speed without high fuel consumption and dangerously slow acceleration. Dashboard light indicated problem with glowplug (diesel engine) and check engine light stayed on. Took to local dealer next day; tech replaced "pressure pipe" (faulty charge pressure sensor on high pressure filter pump) and "flashed" ecm. Engine's acceleration still below what it was prior to event.

Front doors do not lock manually or automaticlly.

Shortly after purchase, car began to fill with water. Not directly from the sun roof but from a disconnected or damaged drain hose. Causing serious mold & electrical problems. Vw has reluctantly looked into the problem, replaced parts, but only made it worse. And the car is now undrivable.
