have you tryed the starter ? when you turn it over does it crank ? try looking over all the vacum lines and check your spark plugs for spark *best done in the dark* in diagnosing a starting issue its always good to know what it does when you try to start it as well.. so in a brief description when you turn the key on does it make the normal buzzing noise to prime the pump, then when you turn the key does it crank over and try to start, if it cranks and doesn't start does it chook or simply not sputter at all .. Start from the top , check spark, so coil wires and plugs. NExt move on to fuel, check the lines for leaks, change the filter if it has not been changed in over a year especialy if you don't use supreme or premium gas. if there is no fuel in the lines and you hear the buzzing you most likely had it installed with the wires backwards or hte filter is clogged. If fuel is fine check all the airways to the throttle body, most cases you may have a clogged filter or your maf is to dirty, Check the vacuum lines and pumps. Make sure here is no breaks or leaks some of the rubbery plastic hoses like to snap from to much heat and old age. Any who let us know how all that goes. and where did you buy your alternators ? perhaps they were not rebuilt correctly. i have been having an issue with alternators myself lately and it was because they were not rebuilt correctly.

google map is your friend just search vw specialist and youl come up with all the specialists in your are for vw and audi. If you been using regular gas that would be your problem and your spark plugs are probably fouled. Audis can only be filled with the best high tes you can find ussaly located at petro can 94 octane.

he is likely speaking of the secondary small wire to the alternator. i had simalure power issues as well when my alternator went ca-put. the cooper end of that wire frayed off on my car and i replaced it with a aluminum tip and it had not been the same since.

replace the wire end with a new copper tip or simply wrap the wire around the pole end and secure it with the bolt.

sounds like you either blew a fuse or a relay best way to figure that out is start pulling fuses and find a junk yard and grab a couple spare relays to test relay slots.

ok tell me everything you have done since the issues started and tell me exactly what it does when you try to start it. for example if you turn the key does the pump make a steady hum for roughly 8 seconds then shutt off beffore start or does it make irratic sounds. anouther example would be when you try to start it does the car stuter or simple does nothing but crank .

I have a 2003 VW Passat i park the car under a pine tree that has small needles for about 2 years after a rainy day I noticed the windows fog up and one day the carpet was wet driver side sponged the water then rained again wet again the the key remote wont work windows wont open interier lights dont work the problem was water under carpet CCM Module full of water broken wires corrosien i replaced wire harnes and module now car wont start i forgot to mention theres a drain under the battery was cloged with pine needles the battery half in water

sounds like you left it parked for way to long. Your at this point probaly dealing with a fuel system that has gotten gummed up from prolonged sitting. First off i would put some good high octane gas in the tank and maybe put an octane booster in. check for any other signs of broken and frayed wires. that battery will likely need to be replaced they are not ment ot be pluged in for over 2 years with out it being used. Once you get the car started i would take it for a nice long drive and get that tank of gas as empty as possible and then refill with high octane again to help clean the system. Shell gas would be the best to use
