Picking up this tread , last sathurday (a week ago now) while driving on the motorway for about 20km afther departure from home i suddenly noticed the orange coil light flashing on my 2012 SE 140bhp
I knew a flashing light was not good and we had to go at least another 150 km to reach destination and back home i disided to just head back home not using the motorway to avoid high speed .
Did some searching on the forum and google and it did not comfort me reading about EGR valve....ect...
Orderd a simple scan tool OBD2 online hoping to get some info , witch arrived two days later by mail , but did not got any wiser , deleting the errors did clear the flashing light for three sec and came back on .
As my VW dealer is CCN in Amersfoort (Netherlands) i phoned them up asking what might be the problem they first asked to check the breaklights (i knew about that thru google) than they asked if i felt anything strange driving witch was not (revs,engine power,...) they said it would probally be a exhaust themperatur sensor and i was ok to drive but no long distance. I am not going back to the VW dealer i got the Cali in Belgium as they are crap so i phoned a good friend who is 25y automechanic and works in a decent all brand gargage asking if they got the tools to connect to VW software , they had it offcoarse handeling a lot of German cars .
Brought in the next morning , we hooked it up on the professional scantool and a failed exhaust themperatur sensor came up indeed !
He orderd it and putted it in and a second sensor then came up to fail and even a thirth.....
Ending up with three new sensors at 150€ each plus work about +560€ ! 450€ for the three sensors (original VW parts) and only 110 € labor + some small extras.
Having done 45.000km in 5 years mainly longer trips and frequent highway (no daily driver , short rides) i am wondering what caused it.
This came up the scantool

Translating:
Nr. of faults 3
Unknown fault
Exhaust sensor
System 1 sensor 4
Faulty signal
Exhaust sensor
System 1 sensor 4
Electric fault
Strange only one sensor (nr 4 ) came up first as in the end there where 3 out of 4 faulty.
Try to get some picture of the sensors

Got the Cali back yesterday and dicided to take a ride doing some km as i was plannig to head to France next week and wanted some peace off mind afther a few sleepless nights worrying the EGR had failed.....
Did a trip to CCN Amersfoort , unfortunate there we no mecanics today (sathurday)so did not got to ask a lot of info , drank a cup of coffee looked my eyes out in the showroom filled with T6's and head back home .
350km round trip , all fine , off to France on thursdayevening!
