• VW 1.2 petrol Polo - Throttle Body Fault 31 Oct 2010 (Forum)
  Not having owned a 'modern' car before, I wasn't used to all the electronic management systems and wasn't surprised by the intermittent whirring noise from the engine compartment. However (it's my wife's car) when I got a call to say the battery was flat, I started to wonder. Knowing that it probably wouldn't be a dud battery, more likely a combination of the exterme cold weather we had last winter and short journeys with everything switched on, I jump started it and hoped for the best.

• BMW 3-Series E30 (1983 - 1991) - 1989 1990/6 Fuel injection air valve running with 10 Nov 2008 (Forum)
  You can hear a faint buzzing noise and when you touch it, it is vibrating gently. If I leave the battery connected between runs, this fault soon flattens the battery. The car has been off the road for about six months. In that time, the battery was disconnected. When I came to reconnect the battery, this symptom manifested itself.

• Hybrids - best or worst of both worlds? 2 Nov 2021 (Forum)
  Typically hybrid cars have very small batteries. They can go very little distance (often less than 2 miles) on EV mode, if speed is typically less than 20 MPH.  On the flip side weight of battery + hybrid equipment is about carrying 2 extra passengers.

• Mazda 6 '55 plate diesel - Starting problems with key 23 Jul 2010 (Forum)
  If he tries again, sometimes it will start without problems - other times he has to remove the key and try again and it works. I did think that maybe the battery needed changing in the plip but it seems to unlock the car at quite a distance, so i think the battery is ok. Anyone out there have any idea what it could be? Thanks Robin the Technician
