Error Codes ID Please!

Recently got the engine replaced on my 2001 X5 3.0. The other day check engine light came on and these were the codes:
69
126
191

Any ideas what they might be?

Thanks.

Where are you reading these fault codes from? Fault codes generally start with the letter P followed by 4 numbers - see those at the end of this list:

The shop has one of those professional obd readers that looks like a spaceship control unit, that's where we've got the numbers.

I found some more details here :

I think it might be related to the new battery the shop had to put in, but we'll see...
