Hi All,  new to forum.

 

I have problem on 2010 Octavia 1.6 tdi.   Car goes into limp mode with flashing light and code seems to be 07462 - im using a carista dongle. I cant find any info about this code.  The fault does not seem to appeat when a. car is cold eg in first few miles. b. when car driven hard - only appears at low revs when car warm..

Look at DPF issues. What kind of mileage do you do? Take the car for an Italian tuneup (low gear, higher revs - around 3000rpm [when warm]) and go for a long drive. Put in a tank of decent branded fuel (not supermarket).

im suspecting DPF  sensor as I used a snap-on mobis scanner yesterday - Ive got the part but no way to do the adaptation.  I have a tech question on this if anybody can answer...

 

I assume the the EMS is continually taking readings from the DPF vac sensor to calculate how full the dpf is.. and eventualy does a regen when it thinks it needs to,, I get that.

 

I assume the adaptation required to calibrate the new sensor to the old reading of how full the dpf is....I get that.

 

But if the sensor is going faulty the the EMS might store the wrong reading anyway and when you adapt the new sensor - then the EMS still has wrong reading of how full the dpf is....
