Really? You had THE SAME THREE CODES?????
1 in 300? That's a recall
Try one in 10,000
id be hard pressed to suggest he chase after DME issues .
OP, how do you know the battery is good? 'Holding a charge' is not a great test. If the car did the same things before, and that was a bad battery, it would seem easy to rule out a battery. Like 200 euros easy...
