Anti-pollution fault. peugeot 307 1.6 petrol;
APF warning came up on petrol 307 (60,000 miles; 03 plate). Took it to garage paid £25 to read the diagnostics.... said it was a "speed sensor fault". They also told me there were a number of the sensors and they couldn't tell which one from the code. Would have to replace one by one ... don't really want to have to do that.
APF warning disappeared after diagnostics only to return a week later on M5 doing about 70 and decelerating at the time. Car seems more jerky than normal in low revs and "bubbles" at idle but does not stall. No loss of power (although not known for their zoom it's no worse than normal). It's had a recent service and ECU upgrade.
What are the speed sensors (they said there was one on the flywheel)?
Is it OK to drive as it is?
