Just had this pop up on the dashboard, last thing I expected to see on a PHEV.  Car drove a good distance a couple of days ago with the engine running, first time this error has popped up. 
 

code from OBD Eleven is P1A9100

 

anyone had this with an iv?  Couldn’t find anything on the VW GTE forums.

 

pretty much runs in electric the whole time (<20mile journeys) except for longer journeys where hybrid mode is used.

 

Skoda assist coming out to see it with a skoda tech on Friday morning.  Couldn’t get the online manual to work!

Thought I would update on this.

 

Mrs Globalste drove the car to work in hybrid mode, this forced the engine to sit at 2000rpm constantly and not use the battery at all, when she got to work the light had extinguished.

 

however, I wasn’t too happy it had turned on in the first place and my OVDEleven was showing a few other errors so Skoda Assist came out.

 

the guy from Skoda could see what the car had done but ran a regen on the driveway and sorted a couple of recall items.   Then the car decided to throw a wobbly and EPC light came on and he couldn’t clear it, something to do with the camera.  So now it’s got to go into the dealership to be sorted out, but annoyed really as we are supposed to be going away this weekend and I’d got the winter tyres and the roofbox on, now I’ll have to take it all off and probably get a VW Up rental! 😞

Do you have battery charge mode?  That should put the most stress on the exhaust creating the relevant conditions for a good regen.  Obviously you need space in the battery or it wont run as much.  

 

TBH I'm surprised it has a GPF given how they are designed be able to run on the electric or having the engine cut out when going along.

 

Does the skoda have the equivalent of GTE mode?  On my Passat this is similar in function to hybrid (obviously more powerful) but the engine doesn't cut out when over about 50mph.  Might be a better option for longer journeys to avoid this in the future?

This is a good tip, I did think about something like that by using VRs/Sport mode and setting the manual battery to maximum but I wasn’t sure if the engine would run the whole time.  Like you, I just find it really weird that the GPF would even light up but maybe if the engine is hardly being used except really short blasts it can clog up quickly, just not sure why it did it after a long drive the day before which is why I called up Skoda assist - the guy said he’d only heard of it from his WhatsApp group and that was on a Passat (so same car I guess).  He said he gets it a lot on the 2.0TSi though.
