Hi guys, looking for some wisdom!

Leon st 1.8tsi dsg 64 plate

Car is due mot in 5 days, the epc light comes on when started from cold most of the time, when warm maybe 3 out of 10 times. It's having a full service and mot at a random garage tomorrow due to time, I left it too late to book in at my usual.

I took it to get it fault scanned at came up with 2 codes P256300 and P034100. They said they will start with the cheapest option first for resolution.

I've googled all sorts and read anything from brake sensor to new turbo (actuator problems or something sticking?). Obviously a new turbo is not at all going to cheap.

The car drives fine when the light is on, no noticable power loss or any other side effects.

I'm not sure how clued up the garage are so are there any pointers anyone can offer or parts to check which can lead to said faults? The car has done about 45k I think from memory and certainly due a service.
