dellboy100 Posted September 10, 2013 Posted September 10, 2013 Hi guys, I have a 2001 C5 auto desiel estate. After a lil advise. When the car gets hot, it has trouble engaging gear and over revs. I have had the gear box checked out and the codes are saying that the ABS ECU is not talking to the gearbox ECU. Is this likely to be a simple bad earth connection or a screwed ABS ECU? The other prob is that when I use the rear wiper, the tailgate opens! Also, is it normal with the C5 to be able to operate the windows and wipers and other bits with the ignition turned off completely? Thanks. Dellboy100 Quote
paul.h Posted September 11, 2013 Posted September 11, 2013 Welcome to the forum.I can not help with the gearbox but if you post the fault codes this may help others to advise on the problem. Check the wiring for damage between the tailgate and body. The windows and wipers can be used for a short while after the car has been switched off and the key removed - the front wipers to put them in the vertical position for blade removal, the windows so they can be closed - this is also possible on the key fob window button so they can be opened a bit. I have moved the post in to a subforum since outside of these they tend to get lost and not be seen and after a few days are not visible. Quote
dellboy100 Posted September 11, 2013 Author Posted September 11, 2013 I don't have the codes because nothings coming up. When I got it checked at the transmission place he said the ABS ECU ain't talking to the gearbox ECU so it's not recording the speed or something. Cured the tailgate/wiper/central locking issue, removed the rear wiper fuse from fuse box. Everything else works and I can lock the car so happy about that. May have to remove the wiper tho cos its an MOT fail if not working where fitted I believe. Quote
paul.h Posted September 15, 2013 Posted September 15, 2013 The rear wiper may be outside the MOT, you can check in the MOT testers manual on one of the direct.gov sites. Quote

dellboy100 Posted September 16, 2013 Author Posted September 16, 2013 Great thanks guys at least that's one worry out of the way if my mechanic can't rectify it. Quote
