Evening guys, any ideas? It’s not always, but most of the time.
The second I slow down to 30mph or under it stops flashing.
I’ve got a few issues with this car, only had it 2 weeks and the dealers are no help whatsoever.
Its a 2015 Wrx Sti.
many thanks

Check all tires are the same rolling radius. If a new tyre has been put on and the others are half worn it will throw an AWD light as the rolling radius causes an issues with the diffs. All four tyres need to be replaced at the same time.

Thanks Dan, it’s had the wheels changed from standard so it could be something to do with that then

What’s the wheel and tire setup now? If they are a staggered setup that would cause issues too.

18” Bola B1s, can’t remember the tire size but I’m sure they’re all the same I did check that

Dan.jo

Get a tyre depth gauge and check the tread depth. If they aren’t near enough equal that’ll be your issue. That’s the most common cause of an AWD light.

Wow, that seems overly sensitive?
thanks for the help 🙏

Dan.jo

They are sensitive in that regards, yes.
