Something snapped/popped while driving. Citroën C4 Picasso
“I was driving on the motorway. While accelerating, there was suddenly a loud bang, like a champagne cork popping, and the car shut off. Then I could hear a strong hissing sound, like air escaping.
I’m home now. I tried cranking it — you can hear the engine trying to start, but it won’t.
There are no oil or diesel leaks.
(It’s a Citroën C4 Picasso.)
Do you think the timing belt/chain could have failed? Or is there a chance it’s something else?
I haven’t opened anything up yet
