Hi everyone,

This is my first post on this forum, wich i really like by the way. I found a lot ouf usefull stuff here.

So i just got a USB to obd2 cable from ebay and scanned my car. Here are the codes i got :

18010 power suply terminal 30: voltage too low [Power Supply (B+) Terminal 30 Low Voltage]
P1602 - 35-10

and also

17884 EVAP Emission Contr.LDP Circ Malfunction/Insufficient Vacuum
P1476 - 35-00-

I search on the forum but couldn't find any solutions.

My car is a 97 A4 1.8T FWD
Vag com version is 4-09 Us

Also i just got the car a week ago, so im kinda of a newbie :P

I would apreciate any advice on how to solve those problems

 

The first code is no big deal. It just means the ecm lost battery power. It was probably set when the battery was changed. The second code is an evap pump failure, or a wiring or vacuum failure to the pump. There is a vacuum line that go to the pump(which i believe is located under the left rear fenderliner on your model). It is a vacuum pump. There is also a solenoid that controls the vacuum at the pump. If you have a vag com you can run the evap test. Its either 70 or 71 in basic settings. While the test is running make sure you have power and a ground on the two wire connector at the pump. Also make sure you have vacuum at the line going to the pump.

Thx guys for those great infos.

I don't have the time right now to check all that because i have a lot of exams.

Can i still drive it for like one or two more weeks without causing damage????

The vacum pump is the gaz pump right?????

 

It has to do with vapors from the gas tank. You should be able to drive
without damaging the car.
