Hello, has anyone any experience of a failure of the 5F unit. Car is just up to 4 years old only done 22k, infotainment system not working and it won’t go into hybrid mode. Local VW have diagnosed failure of 5F unit. Another garage is saying replacing this wont fix the hybrid issue. Cost to replace is £2300. Anyone any experiences? BTW no goodwill from VW or dealership. Anyone experienced similar?
