Stage one software upgrade issues

Post by Ralpf »

Hi Guys. I am driving 2009 1.4tsi scirocco. I did stage one software upgrade. I then experienced issues with epc and engine light together with misfiring. I changed coil packs and put in NGK BKR8EIX sparkplugs. Putting pedal to metal, the problem still same.

Anyone that can help?

First thing to do is scan for the fault codes that are triggering the lights and which cylinder(s) are misfiring.

Also, if it is only started happening after the software upgrade then I would suggest speaking to whoever did the upgrade.

If it's the twin charger engine (160bhp), it would be worth getting a compression test done as those engines of that era suffer piston issues. If, as your profile suggests, it's the lower power turbo engine, then ignore this part.
