If you find out will you let me know!
I have a 06 golf & within the last 6 months I got this error message 4 times
usually it happened whilst driving my car & it would just loose speed rapidly.
Once while over taking on the motorway, my speed fell from 110km to 80km in about 2seconds! , but when I pulled in & restarted the car it would always go away & the car would go back to normal. Brought my car to VW garage twice over it & they could never tell me why it happened or detect the error as it never logged on their computer! So becareful driving! My epc light would flash on dashboard usually with the skidding/slippy tyres light! But always when I pulled & restated the car it went away, I'm still none the wiser!
