Hi All - have owned my 166 for 7 months, 2 months ago went to start it in that cold weather and the battery was flat. So bought a new battery and all was well - had the old battery tested and no fault found, but as the car was starting fine left well alone.
This morning battery was flat again, started it with my charger/starter then drove it approx 15 miles and stopped for lunch. After an hour came out to the car park and the battery was fine and started easily, so charging system must work. Been fine for the rest of the day.
Anybody else had this unusual problem? I checked that no electrics were left on, parking lights etc and that the terminals were tight but cannot find any fault.
