back when I was into making my webpage, I started this.....
The A2 / MK2 VW FAQ
1) What does Mk1/Mk2/Mk3/Mk4 or A1/A2/A3/A4 stand for?
It refers to the body style of a vw. There are basically two main chassis designations for watercooled VW's.
The "A" chassis includes GOLF (RABBIT)/JETTA/CABRIOLET/SCIROCCO/CORRADO/CADDY (RABBIT PICKUP)/NEW BEETLE. "MK-1" and A1 are the same thing, the british use "mk" designations which are pronounced "Mark - one" (not "emm-kay one")
A1/Mk1 - - - Rabbit (american name for golf), Scirocco (both mk1 and mk2 sciroccos), Cabriolet,
Jetta, Caddy (pickup) 1974-1984 with exceptions for cabriolet (92?) and scirocco ('88)
A2/Mk2 - - - Golf, Jetta, Corrado with exception for corrado (a few '95s)
A3/Mk3 - - - Golf, Jetta, Cabrio -exception to Cabrio which is still in production (2002)
A4/Mk4 - - - Golf, Jetta, New Beetle
The "B" series refers to the Passat cars. The B1 was known in America as the "DASHER," B2 was the "QUANTUM," B3 and later was known as the "PASSAT". B 5.5 is the latest model Passat (2002) that had visual updates but the chassis stayed the same.
Mk is pronounced "Mark", mk designates the body style, A or B designates the chassis. So a scirocco is on the a1 chassis, but has two bodystyles designated mk1 and mk2. Otherwise all other VW's have the same chassis/bodystyle designation.
2) What repair manual should I buy?
The only repair manual that you will ever need is the Robert Bently, aka Bently repair manual. These are available from the publisher, http://www.rb.com , along with just about every VW parts shop and amazon.com and barnes and noble. These cost around $40 USD and are well worth it, if you are tight on money check out ebay or used book places (amazon and BN have used sections on their websites), sometimes they come around and are cheap.
3) What engines were available?
All watercooled VW's prior to 1986 were some variation of an 8v, none were larger than 1.8 liters. The Scirocco 16v was the first to recieve the 16v in 1986.5 (partway through '86 model year), followed by the GTI and GLI.
Prior to the 16v the GTI and GLI's were equipped with a high compression 8v engine which put out around 100-105+hp. These engines used CIS-e (KE jetronic) which had a knock sensor and control box to manage "pinging." All were 1.8L
The non GTI/GLI engines were low compression which usually put out around 90 HP. These engines were managed by CIS (with o2 sensor aka Lambada) All were 1.8L, some early "GX" engines had smaller valved heads and put out 85hp.
Any engine that isn't a 16v that came stock was a 1.8 liter 8v. These put out 100 hp, unless the engine has a dual downpipe and exhaust manifold. These engines put out 105hp and more torque, they usually came on Jetta Carats or 90-92 8v GTI's. Engine management was controlled by Digifant II, this was VW's first "electronic" fuel injection. Some people refer to this as "digifart or digif*#^", it isn't a bad fuel injection, but it can be no fun to work on if you don't know it.
GTI's and GLI's had these, they put out 123 hp. Controlled by CIS-E
90-92 GLI and 91-92 GTI 16v's (not all GTI's were 16v from 90-92). These put out 134 HP and engine management was accomplished by CIS-e/Motronic. This was VW's first chippable (or easily chippable, digifant II can be chipped) FI.
maybe someone could save these images and host them on vortex, or change the format to a html table...
