Problems with my Seat Leon Cupra R 1M

[Almeiidaa]

Hello guys, i've Vagcom'd my Car and got some errors from it. Also since i changed my Ignition Coil Modules and Spark Plugs to new ones my car started to smoke like crazy, the smoke coming out of it is bright white and it smells like normal gasoline, at first i thought it was my turbo but since it smells like normal gasoline i think it can't be the turbo. I'll drop bellow my fault codes, i would be really happy if i could get some help.

17863 - Exhaust Gas Temp Sensor 1 (G235)

The circuit board in the sensor can fail, causing terrible mpg. Second hand replacement the best way since they're horrendously expensive new.

Probably not connected to your big issue though.

I can supply you with a used EGT and Lambda sensors if required.

I'm confused by the smoke part tbh, white smoke on a petrol/gasoline engine is usually steam caused by coolant getting burnt, but in this case I doubt it. If the smoke smells of petroland it only started after changing the plugs, it sounds like it could be unburnt fuel. I would remove the plugs and check that the electrodes and the gaps are ok.

When it comes to the sensors, I would check fuses and wiring, then maybe take Thai up on his offer of some 2nd hand parts. New EGTs are expensive
http://wiki.ross-tech.com/wiki/index.php/17863/P1455 <<< ross tech website is the best place to check any fault codes.

You can ignore/delete some codes for now:

17705 - Pressure Drop between Turbo and Throttle Valve (check D.V.!) This code can be set in cold weather on cars that have been remapped, it's a coding error and you can ignore it 99% of the time.

18010 - Power Supply Terminal 30 This code just means that the battery went flat or that you disconnected it.
