Car is a 2005 S60 AWD -

Just today 2/17, after a fairly cold night (Temps were down to 15F - 20F)I am having a problem when I depress the brake pedalthe car engine accelerates dramatically. Luckily the brake also engages so no damage has occurred and I was able to shift into neutral. But when I did this the engine kept revving up and wouldn't idle down so I had to shut the engine off. This is a really dangerous problem, much like I heard Audi's had several years ago.

I will get the car into my dealer tomorrow but has anyone else experienced this?

Thanks,

Rich

 

Do you hear any sucking noises in the car?
Im wondering if the brake booster is bad causing a vaccum leak.

 

Tech:

No sucking noises. Just acceleration. The engine just takes off like the accelerator pedal is stuck wide open.

 

I would get to the Dealer ASAP then maybe the throttle body went bad.
