Advice please on engine fault

[DaFoot]

This is the state of my dash at the moment
2L Diesel.

Noticed a rattle/knocking noise from exhaust area when starting car at the weekend (from cold).
I opted not to drive it since then.

So I went to get more info just now and current state:
- engine turns over and starts ok
- first time (cold) I initially got a message about an issue with the adaptive cruise control
- after a few moments the engine cuts out leaving those lights on (the yellow ones I'm bothered about )
- try it again and it starts ok, but after a few seconds, or perhaps if give it a little gas, it cuts out

The 'coil' light is flashing, not solid.

According to the manual, that means:
"Fault in engine management"
and
"Fault in emission control system"

The second one fits with knocking noise from exhaust area I guess.

Can anyone offer any suggestions as to:
- what the actual problem might be (educated guesses welcome)
- single issue causing both problems?
- likely cost
- am I going to have to take it to SEAT (there's a franchise a mile away) or will a local garage do?

A local garage should be able to read the fault codes for you.

Or buy a Carista dongle and check it yourself?

Find a local VAG specialist go there get them to read it and quote you, they shouldn’t charge much for a fault find.

Or like was said previously get yourself Carista or I use OBDEleven to read the faults yourself if your happy doing that.

It's at an independent SEAT specialist now.
They've found 'swarf' in the fuel line. So it's gonna be a big job

I wonder if that's a symptom of service being overdue (so fuel filter/pump degrading) ?
