Well, day 9 in the Portfolio loaner (whilst mine remains off the road), which I will be honest is not a patch on the R-Sport. Feels a totally different calibre of person should be driving this car. Anyhow, got home tonight, popped into reverse with nothing behind me for at least 16feet and nothing either side for 8 feet both sides and parking sensor started beeping, then went constant then clear and yellow and then went randomly into the three varied states of clear too close and approaching something!! This is the bog standard system with rear camera only. There was no cat, bird child or waving plant just the system going into meltdown again!!! I have videoed the problem and send to Jag tomorrow!!! Maybe it's just me? Maybe I have this affect on bloody cars!!!!!
