I've just had the very same thing happen to me.
The wife was driving at about 60mph. Car has never missed a beat til then and total loss of power. Engine sounded like a bag of hammers cloud of smoke and stopped.
It wouldn't start and had to be towed.
Code was P228C.
I've had injectors seals fail before on other vehicles, but the engines still ran, albeit smelly and lumpy.
There are no other codes other than P228C.
It states low fuel pressure when looking up the code.
How can a leaky seal lead to low fuel pressure??
They look easy to do, Ive don't them before on other vehicles - but there are no usual tell-tale signs, I.e. Evidence of diesel around injector tops...
Any help appreciated...
