I recently had the timing belt changed on my 02 TDI beetle, and it appears that I have went from an average 42 to 46 MPG down to 34 to 36 average MPG. The car starts and runs as before. Is it possible to change the computer in the car to rectify this?

Thanks, Ken [email protected]

Yes, timing should be checked. Who changed your timing belt?

If you look through the ALH engine timing belt article, at the end of part 2 it shows how to check and adjust timing.

Hello all of you,
I am very familiar with wrenching as I was an engine rebuilder at an independant garage many years ago, specialising in German products. I have rebuilt hundreds of engines and owned more than 65 VW cars and transporters; also many Porsche 356, 911 series and Audi cars. Unfortunately, coupled with the fact that I am not familiar with solid state control of engines, and also because of age and health I can't do the work any more. I am forced to depend on the few garages that will work on this car. Ah; for the good old days of carb jetting and hands on ignition timing. But it sounds to me, after searching this site and talking to you guys, I should be able to buy a VAG-COM adapter cable, and with my laptop do a few virtual things to this engine. Does this sound like a plan to you fellas?
Thanks for the help,
Ken Bohn

Great collection...you sound like you certainly know your way around a car!

Yes, I would buy one. They are an essential tool for working on modern VW and Audi. In addition to engine functions, there are also other settings which can be changed. For example, you can set it so that all doors open with the first press of the unlock on the remote. More info in the FAQ.

Yes Ken I'm sure they are worth having. I would love one the problem is not so much with your 2002 Beetle but laptops today don't have COM ports which the older cables used so you probablyl need a HEX-USB+CAN cable.

Vehicle Application Charts

But they aren't cheap though you will find the older cables on eBay for your Beetle quite cheap but I don't know how reliable they are as they are mainly from China, I'm not saying that Chinese goods are bad.

Thats another reason to have a http://www.myturbodiesel.com/forum/f10/vcds-vag-com-section-here-3918/ on here chitty? ;)
