Coil lights back on after EGR & exhaust gas temp sensor changed

[baconandeggs]

Folks

I am in a long running saga with these damn flashing coil lights. I had the exhaust gas temp. sensor changed which the computer claimed to be the problem, lo and behold it came back soon after. This time it was the EGR valve. It has now been changed also and now after about 30 miles driving the damn lights are flashing again. It is a matter of time before the engine light will also now flick on.

What on earth is going on??

Cheers

Is it possible parts are being changed based on fault codes only? Reads that way.
Can you post codes that have retuned?

I am guessing a Polo 6R TDI 1.6 with a CAYC engine?
