The Mechanics Quiz

In this Article I give you Volkswagen, Audi and Skoda or VAG engine
management fault codes. These come in 3 types either 4 Digit, 5 Digit

of P codes. These codes cover all European models including:

Golf, Polo, Jetta, Up, Fox, Beetle, Passat, Scirocco, CC, Phaeton, Eos, Touran, Sharan,
Tiguan, Amorak, Touareg, Caddy, Crafter, Transporter, A1, A2, A3, A4, A5, A6, A7,
A8, S1, S3, S4, S5, RS3, RS5, R8, Q3, Q5, Q7, TT, Fabia, Octavia, Superb, Citigo,
Praktik, Yeti, Roomster and more!

The best way to quickly find the code you are looking for is to press ctrl+F on you
keyboard and type the code you have in to find it on this page.

I do love cars, especially the models that are heavy loaded with all types of decorations. I cant say
that a Volkswagen is the only car that i find attractive, since a limousine has always been my
favorite. Owning a car means that you need security, and therefore Making Metallic Gates could
be necessary. To have a secured compound, why not visit the link and find out how a metallic gate
can be assembled for you.
