Hi guys. I have a 52 plate 996 3.6 targa . I didn't use the car for 3 weeks and the battery went flat . Charged it up and car started fine . As I was driving I noticed the central information centre in the dash binical went off for a second then came back on . I'd did this a few times over 45 mins then went off completely. Next day started the car and all was good . After a short time driving the information centre went off then came back on . After a while went off and stayed off . Does the same every time I drive it . Any ideas
