Woke up this morning and the rs wouldnt start so i bump started it thinking the battery was dead and then drove it around for an hour or so thinking this would recharge the battery, i tried to start it up once i got home and its just clicking now, everything works ie lights hazards cd player, iv tried hitting the startor motor and nothing has happened. anyone have any ideas thanks in advance.

 

the battery is completly fooked mate. thats all.

a new one should sort it out

 

Or your altenator isn't charging the battery any more...

 

but if it wasn't charging when it was running it'd stall when at idle i'd have thought, i stand to be corrected though

 

if your alternator wasnt charging the car would not of run for a hour with a flat battery, id say starter or battery, have you tried putting a volt meter on the battery with it running to see what power is there, should be between 12 and 14 if i remember and then check when you turn it off.

 

ditto. but should be anything above 12.5 if your alternator is in good nick... also try the same test with all your electric stuff turned on (full beam, heater, heated screen, blower wipers etc) see how much the the voltage drops (you could have a shite wire from the starter motor to the alternator causing volt drop!)

having said all this from what you describe I am guessing starter is fooked!

 

batteries get fucked overnite sumtimes. just the way it is. once battery is knackered then thats it.

get a new one mate. i got like 640a battery from euro car parts, just fits in

 

One thing to check as well is that your boot light isn't on all the time. The switches are temperamental and if it is this drains off the battery without you knowing. Just pull the back seats forward and check without opening the boot lid. If it is just pull the bulb out. This has happened to me on several Mk4s now. You might need another battery as well but it'll stop it happening again if it is the case.

 

if everything else is working and bttery has power then its ya starter motor m8

 

had exactly the same problem.. new starter fixed it.

good luck bud

 

I would be wanting a minimum of 13.4 volts even under load , an off the shelf battery should have 12.6 volts, 2.1 per cell
