Flashing DCC-button (Comfort / Sport)

[Ludsci]

Hello.

I've got a Scirocco 1.4l TSI -10 that has a flashing "DCC"-button, you know the one that has option for driving modes such as "Comfort" and "Sport".

I have been trying to read through the posts made on this forum about this fault but I have yet to find someone who truly seem to know what causes it. So I will try myself to see if anyone knows and I would be very appreciative for any help!

I haven't been able to re-create it but somewhere mid-drive it seems to start flashing. I do not know when it starts as it, to me at least, seems very random.

Thanks in advance!

Hi,
My DCC light flashes constantly - the VW Dealership diagnosed it as a sheared sensor wire when it was in earlier in the year for a DSG service. So I’d suspect that you have a dodgy sensor or perhaps a loose sensor if it only flashes sometimes?

I’ve not replaced my one yet as a new sensor from VW was quite expensive for the part and it didn’t affect the car’s MOT.
I don’t know if that’s any help to you…

There is no single cause, but as Snug335 suggests, possibly a sensor fault. As in the case of any fault indication, the first diagnostic step would be to interrogate the fault memory, which should hopefully pinpoint or at least narrow down the fault
