Continuity mistake: During Robert and Sophie's escape from the Louvre they head toward the Gare Saint-Lazare when they realise the American embassy has been cut off by police. However, in the very next chapter they arrive at the Gare du Nord, a completely different station.
Continuity mistake: Robert Langdon has a lot of problems with the manual gearbox of the car that they're driving. However, in the book "Angels and Demons" he doesn't have any problems with a car he's driving in Rome. Although this could have been an automatic, you should realize that such cars (especially older ones) are not very common in Europe.
