general problems of the 2002 Volkswagen New Beetle

The blue temp gauge comes on for a short period of time. . . Then when I slow down the jumps/jerk really hard. . . I notice it only does when I slow down. . . . To avoid it I try to let the car slow down on its own but it still does it. . . . Others that ive discussed the issue with advised me that it may be the transmission. . . And upon researching the vw beetle I found out that im not the only person experiencing this is issue and that it is indeed the transmission.

In August 2008 I went to have my oil changed at a Volkswagen dealer in kalamazoo, mi. They said that the aluminum oil pan plug had been overtightened and the pan was ruined. I was told that potentially the plug could have fallen out at any point in time, leaving me in a dangerous situation, either stranded somewhere but most likely causing a crash. They told me that the aluminum pans wear out and need to be replaced, but this car had only 35,000 miles on it at the time. Something like an oil pan shouldn't just "wear out" after that short a time. They also told me I was better off replacing the aluminum pan with the steel because the aluminum was susceptible to punctures from almost anything. The new Volkswagens are being manufactured with steel pans and Volkswagen should be willing to replace the old aluminum free of charge. The new pan cost me $293. 69.

I have a 2002 vw New Beetle. Problem. . Engine light comes on, then goes off. Had many costly repairs. Problem reoccurs. Mechanic stated that I may need a new catalytic. Have been told that car maintains an 80,000 or 7 year warranty. Is this true and if so how do I get my car fixed ASAP before this warranty expires? car has 54000 miles and is now 7 years.
