Hi,
Sorry to have created so many threads but I have one final question and some advice if anyone else has seen a problem starting.
Question: When I switch on or switch off there's a short buzzing whine from behind the dashboard. Does anyone know what it is?
Advice: If you sometimes find that your Jazz struggles to start and turns over many times you may have an idle stop issue. I've noticed it happen when I park in my garage and have finally worked out that it happens if I switch off while idle stop is in the process of restarting. Previously I'd come to a halt (idle stop kicks in) then quickly push the gear lever to Park and switch off. This caused the issue. The fix is to be a bit more patient and give the engine a few seconds to stabilise.
