Hi guys. I had a remap, Pulstar spark plugs and aftermarket air filter all gone in yesterday and the car drove amazing home. Today the engine light came on a few times and my car shudders and doesn't have much power! Any thoughts? Thank you. Ian. 2011 vRS Octavia TSI

Oh it's a DSG.

You would need any codes to be read. Id take it back to whoever mapped it and get them to sort it. Could be anything. Can you put the orginal air filter and plugs back?

It could actually be a bad plug from new. Very very rare but i have seen it once. Like mentioned back track a little if you can so put old plugs back in along with original filter. If it's still the same phone your mapper. Where did you take it for the map?
