2010 audi s3 wont start

[andy1]

hi i tried starting my car earlier today and it took aboit 10 seconds to turn over and a brake warning light came up on the dash. i turned it in and off and the car started and ran as it normaly would.

i went back out after work and the same happened again but now it wont start. theres a clicking and beeping noide from the fuse box under the bonnet.

Anyone ever had a similar problem or know what my issue could be ?


the car is a 2010 s3 s-tronic if that makes any difference ?

thanks Andy

Hi Andy,
If relays are chattering this normally indicates low voltage (relays need 10.8 V to energise so tend to go a bit mad if operating close to the lower limit). Does the car have a healthy crank? Can you confirm your starter battery is good?
