Hello All, Thank you for the Nissan forum; especially on a bitterly cold day and some pretty awful conditions out there. I have had Nissan's for most of my driving life (37 years). My current Nissan Micra S (Year of Registration 2001) I bought from new. It's gone on and on - very reliable. After a couple of days parked up due to bad weather, I took it out this morning for a short (2 mile round drive) to the supermarket. As I pulled away, for the first time ever I had a beeping noise. This continued until I arrived at my destination and turned the engine off. After a brief shopping jaunt I returned to the car and exactly the same thing happened on the way home. The beeping starts when I pull away and begin driving. I've looked around the forums and am finding everything from carbon monoxide poisoning alerts to low tyre pressures (and more). Is anyone able to define this more (on a car of this age - 82K on the clock - regularly serviced and MOT's at the same time each year). Thanks! REM
