So recently I purchased a used Audi A3 and it was fine until a couple weeks ago where I started to get this coil warning light moments after I started the car. The car would go into limp mode. When I turned the car off and on again it would work perfectly. I took it to the garage and they replaced the turbo actuator yet the error is still occurring. Anyone had anything similar to this or know anything about this? Any advice would be greatly appreciated!

TIA

Yeah, it's the car angle sensor, and it's flashing because the axles are vertical.

More seriously (I deleted likely because, after all it is an Audi), it's the variable vane in the turbo seized. - new turbo required. (diagnosis by internet, without even looking at anything, so there is possibly some error here). BKD engine by any chance?

Get the car scanned for fault codes.

You are just guessing otherwise.

Check that your brake lights are working, a faulty brake lamp switchon VAG products will illuminate the glow plug warning light. (very common fault )

As mentioned, could be a myriad of things.

Happened on my bluemotion diesel polo several times, once turbo borked, another time there was a split in the air hose to turbo meaning drop in boost pressure and hence limp home mode
