Just a bit of info, I tried to get hold of the Bosch battery for Trudy’s car, couldn’t get one unless i had a wait a week for Bosch to deliver, so i ended up with a Varta Silver Dynamic battery.
I have just seen a picture of the Bosch and both batterys are identical even down to the part no: 543 107 048
So if you having trouble locating the Bosch branded one, try asking for the Varta Silver Dynamic.
