What are these red lights in my tachometer?

I think it's tied to oil temp since it can show only 4,400 rpm with coolant gauge showing normal. Have to run for while after coolant at normal before redline goes up to 4,600

I don't have any orange lights in my 2013 tach, only red, and they immediately light up to 6200 rpm when the engine is cold. Maybe it's only a TDI and 2.0T turbo thing?

I dont have orange lights either but mine goes to 6400 rpm since I start the engine, are you sure yours is 6200?

S6's do. Also if there was an engine issue and the computer wants to limit the rev's the lights will change to the computer enforced red-line.

Seems to me to be a turbo-only feature

A side question: do all brands and models of auto diesel engines have turbochargers by design?
