SO I had my motor in my 2001 A6 2.8L Quattro rebuilt. It runs awesome now but now for some reason the front low beam light does not work nor does the signal. Any ideas on how to trouble shoot this without taking it to a dealership or a garage. It worked fine before the engine work as well did the headlight bulb. I think it is funny that neither work now.

I had a similar situation after engine work on my own A6. Major engine work typically requires removal of the front bumper and then sliding forward the radiator support cross-member, as if it were a chest of drawers being pulled out. In preparation for that, the headlamps are typically kept attached to the radiator support cross-member but disconnected from the rest of the electrical system.

When the work was done on my car, the headlamps were ostensibly reconnected as part of putting everything together, but it can easily look like the connection to the headlamp-and-signal structure is good but it's not quite solidly connected. It needs to be firmly seated. On my car the connection was tight enough for the high beam to work but not the low beam. Seating the connector more firmly fixed the problem for good. So, that's my best guess.

Another guess is that inadvertently a short-circuit briefly occurred and this blew the fuses. As I recall, if that's the case, you have three separate fuses to replace. If you have questions about the fuses, please ask me.

It could be a combination of both issues ...

Thanks so much for the ideas..... can I get which fuses need to be checked I have time this week to check them.....and also. Can I check those connections without the bumper and stuff being in service position?

thanks so much again

Hi Stanley,

I plan to look up the fuse amperages and positions for you today. If you have an owner's manual, I should also cheerfully point out that the fuse information is in that book, toward the back. I collect and sell these owner's manuals, but sadly I don't have one for your car. Would you like one? If yes let me know and I'll look out for one in the future.

Yes, fortunately, you should be able to check the connections without the bumper coming off and the cross-member going into the service position. In my case it was a situation of: while driving, my friend the Audi guru noticed the inoperative headlight, and she asked me to pull over. I opened the hood, and she hopped out, rummaged behind the headlight ... gentle push,click, problem solved.

I'm looking at page 209 of the 2000 A6 Owner's Manual. I'm guessing and hoping the 2001 model A6 fuses are similar.

The fuse box is divided into two sections, top and bottom. The top uses mini-fuses only. The bottom uses normal fuses, only. The ones you need are all in the top section, hence mini-fuses.

Fuse 2 is turn signals, 10 amp, red. Top section, leftmost column, 2nd from top.
Fuse 20 is low beam, right, 15 amp, blue. Top section, rightmost column, top fuse.
Fuse 21 is low beam, left, 15 amp, blue. Top section, rightmost column, 2nd from top.
Fuse 22 is side marker and tail light, right, 5 amp, amber. Top section, rightmost column, 3rd from top.
Fuse 23 is side marker and tail light, left, 5 amp, amber. Top section, rightmost column, 4th from top.

I hope his helps. If you cannot find the fuses locally, let me know. I have some.

If you paid normal money for the rebuild and it was recent then I would at least call the shop and explain your concern. It is reasonable they may have not connected all the wires during the re-assembly. If not, it is their job to take care of this.

Just throwing my two cents in this hat......Check all ground wires near the core "radiator" support and off all relative wire harness's.

thanks to everyone for the help and ideas. I just need some time to do it....wish me luck

Mikaere808

So, I reached down there and jiggled the connections and they came on and worked fine....thanks again for everyones help and ideas.

jcman

You have the golden touch! Excellent until you hit that next bump so clean-up that connection when you narrow it.
