Hi guys,

I am new here i own an Rs6 c5 recently i had loads of issues with wiring and fuel lines took 2 months to sort it. Later when it was sorted i drove the car it was fine initially but after few miles the transmission went in limp mode and wont shift to second gear.
Now i have shown the car to A transmission expert he says its electrical issue and the code i am getting is voltage low 30 etc.

My car did took a very long crank to fire up for first few times. Battary was weak indeed.

Can a bad battery cause the transmission to go into limp mode.

Your help and guidance are welcome.

Regards

Faisal.

Have you run a VCDS scan? My first suspicion would be the F125 switch, unless the actual gearbox has been behaving oddly in a way that suggests something internal.

The transmission is recently rebuild by Dexol. They recon its electrical issue. Now i am thinking of installing a new battery and seeing whats what.

Post in the C5 section, you will get more responses.

make sure your wirings are installed and grounded properly that's the common problem in replacing a new battery or better to take it to audi specialist to give you a real time advise
