Jetta 4-cyl Diesel

  • 80,000 miles


At approx 80-90K I started hearing a clattering noise from the engine and extra noise when idling. Also, the car has a hard time shifting (automatic trans). After taking the car to a mechanic, I was told that it's the dsg dmf coming apart and rattling. After doing some research, I find it's a common problem. It started happening shortly after my car went out of cpo warranty, which expired at 74K. I didn't really pay that much attention to it until it got worse. This is a 06 tdi mkv with auto dsg, brm engine. Also experiencing difficulties with soot in fuel filter, likely due to faulty seal in fuel injectors under cam shaft. Once again, common problem according to mechanics and online forums on this model. There's a recall on the dmf for this model in australia, needs to have one for us.

My wife and I were driving home and suddenly my car started jerking and made a "knocking" sound, without any warning (I.e. check engine light). We were close to home and decided to continue on; however, in the next couple of miles, the problems persisted, still with no check engine light or any indication of what was wrong with the vehicle. Over the next several days, while parked on a secured premise, I started the car up and it had an erratic loping sound. I proceeded to call a nearby Volkswagen dealer and spoke to two certified VW mechanics, who failed to acknowledge the issue that there was no warning indication before the car started to act up and said to bring it in to swap out the engine at approx. $7500; they dismissed the problem as "normal wear and tear". I researched the problem on the internet and it lead me to believe that it was a problem with the cam, which I had confirmed by an auto-mechanic after towing the car in. He told me the entire engine was warped due to the cam going out. Other 2006 VW Jetta tdi owners have commented on the same issues, which at this point leads me to believe that it is not "normal wear and tear", but a manufacture defect.

The contact owns a 2006 Volkswagen Jetta diesel. The contact stated that the high pressure fuel pump was malfunctioning and causing the vehicle to stall. The vehicle was taken to a local mechanic, who stated that the fuel pump had metal shavings inside of it that were clogging the fuel injector. The mechanic also stated that the entire fuel system needed to be cleaned and the high pressure fuel pump and injectors needed to be replaced. The contact notified the manufacturer and filed a complaint. The manufacturer informed the contact that there were no recalls, but they were aware of the failure. The contact stated that the stalling could lead to a crash. The failure mileage was 55,000.

Jetta 4-cyl Diesel

  • 80,000 miles


VW has changed the diesel engines (tdi) starting with approximate year 2004 until 2007, when they stopped selling tdi to meet emission requirements. To save money and licensing fees to Bosch they have changed from common rail system made by Bosch (feeds the diesel fuel to engine with very high pressure) to VW system called tdi pd: Pump duse (or pump-nozzle injection). To accommodate the injectors inside the engine, they have changed the specs and dimensions of many parts, including the camshaft. The camshaft inside this engine has the added role to drive the pd lifters, apart from valve lifting and closing. I own this type of car VW Jetta 2006 tdi, and the camshaft wore off at 80,000 miles, and yes it was out of warranty and it costs $3000. Apart from the costs, which accrues to aprox $3000 per 50,000 to 80,000 miles rendering this car a liability cost to the owners (a long term owner will have the price of car doubled by added bills to change the camshafts many times. This impacts drastically financially many families depending on this car), without the possibility to fix it permanently and for once. I have changed the camshaft and now at 115000 miles it starts to shows signs of wear, like last time. Not changing gears in time, car is shaking. The effect gets worse, until when the camshaft lobes wears off more, and results in valves not opening and closing in right sequence and time, and engine will stall, like mine did on my street. As well I was on highway and car will not operate and respond to acceleration pedal input, maximum pedal input was giving only 40mph, exposing me to a stampede of cars from behind in a dangerous situation unable to control the car. I have explained the situation to VW and they deny any: Wrongdoing, design flaw, fault or liability. According to tdiclub.com there is up to 20% failure of the engines via camshaft wear of lobes. I trust you will investigate and request VW to address:safety+financial impact to tdi pd owners.

Sudden deceleration or loss of power mainly at highway speeds but occasionally in town. This lasted for only a few seconds and the car regained power. There were scary situations on the interstate highways but no accidents or injuries occurred. This occurred intermittently over several months but the dealer was not able to either duplicate the problem or identify any components that were faulty. After much persistence and frustration on my part, the dealer eventually identified a faulty ┐tandem fuel pump┐ and a faulty component of the transmission (mechatron). Both components were placed on February 17, 2010 and I have had any problems since that time. Jetta tdi.

2006 Jetta tdi 58,229 miles today / purchased from 2nd owner at 53K miles 34mpg in town / 42.5mpg highway wife driven with light foot. Oil change and fuel filter replaced at 53K miles background: Car was purchased early Dec 2009, with in 2 weeks it was at the dealer for a non start issue. Car was garaged over a 3 day weekend and not driven at all. Monday my wife goes to start it and it will not start, after telling me I try for 3 minutes to get it started and it finally starts. Taken to dealership and they find no issues, they blame cold start as the culprit. This is a bs call as the car was and is always garaged at 50+ degrees F. roughly 3 weeks later the same situation happens and the car goes back to the dealer. To no avail they still could not replicate the issue nor find a solution. The no start issue/ hard start issue seemed to progress from sitting for 3 days and not starting to randomly multiple times a week not starting. They still cannot find a solution. I firmly believe this is a fuel issue. On to today's issue: First noticed 3 weeks ago while attempting to pass a car on the interstate at 70mph (around 4K RPM), the car down shifted and stuttered rather then increasing speed. I thought it was a 1 time issue until I started noticing it more and more. Now it happens frequently and more pronounced starting at even 35mph/3400 RPM in 3rd gear. From 10am Tuesday to 5pm Friday our Jetta was back at the dealership because of a stutter/power loss issue. They did replace the fuel filter today as well as test the fuel (which tested fine), the egr valve was cleaned with a carb cleaner. The service manager drove the car often and has been able to replicate the power loss / stutter, however they cannot find anything wrong. They called the VW tech line multiple times and still no fix once again. Car died several times today. Turning onto the highway the car stuttered and then.5 miles later it died at 45mph in traffic. Pulled over and cranked for 3 minutes.

At 15F degrees or lower temperatures the Volkswagen dsg transmission will impede the diesel engines ability to start, leaving the vehicle inoperable. Vwag and vwoa has knowledge of this system defect providing no solution. Vwoa continues to sell these defective vehicles.
