Seat Leon Diesel Engine Power Loss

My 2016 Seat Leon diesel is giving me grief. It has done some kilometers. Engine issue, feels like it's lost a load of power. And yeah, an error’s stored in the error memory. I'm guessing it's down to some dodgy chip tuning it had done before I bought it. Any ideas?

I have a Leon too. I had a similar issue with reduced power and the check engine light on. Did you use a scan tool to read the fault code?

Yep, used a scan tool and got a fault code. The dashboard light was on too, obviously. Did yours throw the same codes?

Yeah, mine had the same symptoms. It turned out that the previous owner had it chipped and it messed things up. I’d suggest taking it to a workshop that knows their vehicle diagnostics. They should be able to sort it.

Turns out it WAS dodgy chip tuning. Cost me 180€ to get it sorted and put back to the original factory settings. What a headache!
