Jim Bowen 1 Posted July 18, 2013 Parked up and came back to car 10mins later and noticed that the clock and mfa had all reset. Like the battery had been disconnected and reconnected. Car started fine but lost all my mfa info. Had been using the no.2 setting to record mileage since engine change. Quote Share this post Link to post Share on other sites

STU175 0 Posted July 18, 2013 Car started fine but lost all my mfa info. Had been using the no.2 setting to record mileage since engine change.[/ my g60 has allways done this too! never really investigated it. what does fuse 21 power then? Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted July 19, 2013 Fuse 21 was fine, pulled it out and things reset again. Not had the fault again. Quote Share this post Link to post Share on other sites
dragon green 5 Posted July 19, 2013 The MFA has two power sources(fuses) one for when the ignition is on,and one (fuse21)when everything is turned off.Perhaps over time the contact wasn't very good,and it needed resetting ! Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted July 29, 2013 It happened again over the weekend, this time i watched it happen and it did it during me turning the car over. I notice the power cuts from the MFA display while turning it over, has only reset these two times though. I notice quite a bit of abnormal clicking from the rear somewhere while turning it over, could this be related to problem with the fuel pump? Quote Share this post Link to post Share on other sites
Portent 0 Posted July 29, 2013 Check the battery clamps are secure and tighten them. Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted July 29, 2013 I checked that already. Quote Share this post Link to post Share on other sites
VR6 0 Posted July 29, 2013 Checked the earths? Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted July 29, 2013 No i haven't, will give them a check next then. Is there one in the rear somewhere, i specially cleaned up all the ones in engine bay when i rebuilt it all. ---------- Post added at 2:30 PM ---------- Previous post was at 1:10 PM ---------- Anyone know much about relay 18? Wondering if thats something to do with it. Just been out for lunch and all the digital display on dash goes blank when turning the car over, comes back and does remember what was there (most of the time) Quote Share this post Link to post Share on other sites
VW_OwneR_85 2 Posted July 29, 2013 ah mine does this, well the mfa resets itself when you switch engine off , thought that was normal lol , the only info I use off it is for oil temp , would be nice to not have to scroll through the others every time ;) will check fuse 21 and report back Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted August 27, 2013 Just been to a battery place and had mine tested, was only showing 122 cold cranking amps, Aren't they meant to be around 700. Bought a new battery while i was there, will fit it tonight. Car only just started when leaving the battery place, think his little tester took some of my electricity away.

Stonejag 10 Posted August 28, 2013 Worth checking the ignition switch as well. Make yourself a bypass cable and keep it in the car just in case, you may be needing it soon... Stone Quote Share this post Link to post Share on other sites
Supercharged 2 Posted August 28, 2013 Yep +1 for the ignition switch! Quote Share this post Link to post Share on other sites
Tigerfish 10 Posted August 28, 2013 the only info I use off it is for oil temp , would be nice to not have to scroll through the others every time Mine doesn't reset the figures (not that i have noticed anyway) but I have to scroll through it every restart to get to the oil temp, is it meant to remember the last setting you were using?

Jim Bowen 1 Posted August 28, 2013 I have already renewed the ignition switch, only a few months back, i started to wonder if the new switch had an issue. but the new battery seems to of stopped all the funny clicking noises from ignition and the fuel pump, etc Quote Share this post Link to post Share on other sites
n3p 3 Posted August 28, 2013 Having similar problems, clocks go blank as soon as I turn the engine off. Fuse 21 keeps blowing as soon as I put in a replacement. Disconnected the glove box light which fixed my problems for about a day, so it's now a case of checking everything else that the fuse is related to :( Good luck with your search too!

No, it doesn't do that - every time you remove the key it will revert to showing the clock. If it really bothers you, you can mod your gauge cluster to automatically press the button five times every time you start it ;) Stone Quote Share this post Link to post Share on other sites
