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
Its the one in front standing up going in before the catalisator.
The one with the bend in behind the katalisator
The otherone i could not fotograph
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!
