Does anyone a cure for exhaust system warning light showing on 2016 yeti petrol.Cheers

@umpie

Is it a 1.2TSI ?

Resetting / turning off the Light / deleting the fault code is easy, but you want to know if there is a code, and want to know what is causing the light to be on.

Maybe a sensor, maybe a wire or connection so you need someone to check.

 

How many miles covered, and any servicing done like spark plugs replaced yet?

Hi umpie

 

This warning light is oddly named, maybe a translation error.  It means that there is a fault which makes the vehicle no longer comply with its emission standard.  So not necessarily the exhaust system as such. The only way to get more detailed information is to have the stored fault code(s) read.

 

One thing that can trigger it on the 1.2 TSi is a misfire due to deterioration and break down of the plug lead insulation.   The HT voltage will sometimes spark to the nearest metal instead of firing the plug.   I believe Number 3 in particular is routed near the exhaust and doesn't take kindly to being cooked.  Modified ones are now supplied as replacements.  I suggest you check all the leads visually.  The plugs are supposed to be changed every 40000 miles, and wide gaps from worn plugs will increase the firing voltage and aggravate this problem.

The No.3 Lead issue should not be present on a 1.2TSI from 2016 as it was something known with Euro 5 1.2tsi's so pre 2016,  but never take anything for granted.
