Hello ladies and gents,

I need a bit of help!

2013 Superb Greenline, 1.9 tdi, 109k, no emissions fix.
Run almost solely on premium fuel since my ownership (92k).

A couple of years ago (just after I got it) it did an odd thing where it would sometimes stutter in 5th, no apparent reason. But with a diet of premium fuel it seemed to disappear.

Flawless since then.

3 weeks ago (a warm day, parked on hill at work, fuel light on) driving home there was a bit of a stutter then coil light flashing (no engine light), I think it went into limp mode, but it might have just been no turbo, pulled over.

Off and on again, light gone, flawless rest of motorway home.

Filled up with premium juice.

Ran VCDS but zero fault codes on autoscan. (is there somewhere else to find a log???)

No issue since.

Today - after same scenario, warm day, parked on hill, low fuel. Same thing.
Start stop and goes away.

Going to attach VCDS later again, but anyone got any bright ides? Should the fault code not be recorded somewhere? A sensor maybe? The EGR failing?

Thanks as always.

Well today we got a fault code.
P0403
EGR malfunction. Dam

Is it too late to have it deleted and if not is this a bad idea?
