Accidentally left my interior light on and completely drained the battery. Got a jump start and charged battery Now MFA screen is completely blank whereas it was working fine before. Could flattening the battery have caused problem with it. Does anyone have any suggestions? Could Getting a jump start have blown fuse or something (haven't had chance to look yet)
This worked for Golf_BlokeMk2 if you look at the "Rev counter and MFA" post in the Miscellaneous Section of this site. My advice would be to try it again before you suspect the MFA itself. I'm assuming you checked the fuse when you pulled it ? Might be worth sticking a new one in even if it looks OK. Let us know how you get on, but if this failed for me I would be on here asking for advice as to where to look next ! Check back through the forums as this not an uncommon occurrence.
You could try unplugging the battery just to be certain no power is getting anywhere it shouldn't. Make sure if you have any radio PIN codes you write them down beforehand etc. Then try the fuse trick again. Other than that you might end up having to buy a new MFA counter! But I doubt it.

Ok getting silly now, as well as MFA dead, rev counter dead now just noticed that the oil pressure light doesn't come on when I start up. Something fishy going on here especially as all was fine before it went into the garage for loads of work. Think I might just take it back to them and tell them to fix it, might get them to fix the petrol gauge as well which has never really worked. Also had a service at VW garage and they failed to notice that one of the spark plugs was loose which was causing me top lose compression. Not the greatest level of service ever.
Sounds like you may have a dodgy engine earth connection, the Garage might have forgotton to reconnect it after they did the work?
