Codes P1340 and P1531 help

[Heavydee54]

I got the following codes today:

P1340 Timing Chain out of Position, Bank 1 - Below (or Above) Lower Limit

P1531 Camshaft Adjustment Bank 1

My car has 127,000 miles on it. Are these major issues? Is it okay to drive it to my mechanic, or do I need to have it flatbedded?

Thanks.

I see you posted this a few months ago, I just had a P1340 fault and its in the shop now. Did you get yours taken care of? What was the cause?
