Hi Guys,

This issues i back on my car, just wondering if anyone has a solution

The Brake and Battery lights are lit up on my dash, they were dim but now fully solid.

Alternator is charging, 14.8 when on 12.8 when off. Any ideas?

Edit

actually anyone know how many amps the alt should be putting out?

 

i believe its 110 amps

 

i've always wonder what does the ( ! ) mean?

 

i get that when my rims are on and i travel on the highway. after a certain amount of miles of straight driving i get the (!)

from what i was told in the past is the tps sensor. when my rims are on i get this. when i put the stockies back on, it never comes on.

 

^^ thats weird because when i drive on the freeway for a while then it comes on but i have stock 18s. i heard its the tps sensor too but what cud be wrong?

 

hrmm. no idea. did u try the dealer? i have no issues with my stock 17's on the car.

 

110 amps, that sounds right

anyone know how to test amps for an alternator properly?

 

maybe one of my sensors is bad

 

going to do my alternator tomorrow as two dealers say that's it. Hopefully that will fix it.

 

Most likely the alternator needs replacing. I believe that's Nissan's standard indicator for an alternator going bad. My Maxima did that, and I had to replace the alternator.

 

does anybody know how to know if one of ur tpms sensor is bad?

 

Is this a question about TPMS or alternators?


The (!) light is the early TPMS warning light. It is YELLOW in color and was later replaced with a version with the tire in the middle

The BRAKE (!)(P) light is RED and is your parking brake, low fluid and other brake issue related warning light

 

brake + battery light means there is a fault in the charging system, typically caused by a bad alternator.

 

Bit if you are seeing 14.8v at idle the alternator is working fine.

 

that's the strange part, 14.8v is fine, but dealers says something about diode ripple. This happened a few weeks back and once a year ago. I've duplicated the battery and brake leds by pulling the 10amp alternator fuse. I;ll let you guys know when the new alternator goes in, should be thursday for sure. For now, back to driving the Audi TT
