2000 Volvo S70Electrical systemEngine & cooling

The ets light came on intermittently. The car ended up stalling after being parked upon trying to restart it. Thia is am issue that only the volvo dealership can fix since it involves reprogramming or replacing and programming a new ets module. Fortunately it happened to me in a parking lot and I was able to get it rowed to a shop twice. Now it is going to the dealer.

Twice, within 50 metres of the same spot each time, my car has suffered extreme acceleration whilst I was braking as hard as I could.
