Hello all. Hope I can get some help.. We just replaced the Alternator in a 1999 Audi A4 Quarttro. Everything went just fine, no issues but now it won't crank. Everything seems to have power, Power to the starter, but no crank. Battery ground very clean. Drove in, just wan't charging. Any leads???

1999
AWD
2.8 V6
5 Speed Manual

Turn key and there is nothing, Battery light goes out when the key is turned, and the display center says " Press Clutch To Start Engine"

 

Have you tried checking codes?

 

I did find the issue with the no crank. There is a ground wire that did not get hooked up. However I now have another issue.

I got the car running, everything was great, volt meter was at like 14, and .4 miles later the gauge dropped and the battery light came back on??? tested and say's I have no Alternator output?? Is it possible it was defective, or is there something that could have caused it to die again?? Can anyone help????

Thanks!

 

That is an odd one. As long as everything is now connected including the two/one pin plug then really the only option is a faulty alternator but if that is a new alternator then I would be suspicious that it is faulty and not another underlying issue. Let me know if you find anything..

 

First off thanks for trying to help me.. Kids first car and he wants it so bad and I just don't work on Audi's.

I tore it all apart again, and replaced the Alternator. Got it together and the Alternator made quite a bit of noise on the first start. The battery light went out and the gauge went up to the line between 12v and 16v. So I hooked up my battery tester and it is charging at 14.6 constant. I put a load on it and got 71 amps.

Now I took it for a road test. When I get the motor anywhere near 3,000 rpm's the battery light will start to flicker. I got back as easy as possible. Now if I free rev the engine at about 2,800 the light will just start to illuminate.

Any ideas what be going on?? I really hate to have to pull this thing all apart again!

 

And another one gone!! burnt up another alternator!! Anyone what to buy a Audi??

 

Anyone have any ideas????
