anyone got any ideas why i'm going through a new starter motor every 6 months ?
its fine for ages after being fitted, then every fortnight or so when i go out to the car theres nothing there when you turn the key. you turn the key, the dash dimms, few more tries on the key and it will click, another turn, click, another turn and the starter cranks. over the month or so after this, it will fail more frequently until eventually just giving up altogether.
its not a battery issue, as ive had the polo next to it with engine running and jump leads going over, its still dead, the dash just dimms.
replace the starter and its all systems go again.
all i can think of is poor quality reconditioned starter motors (i dont think you can actually buy brand new ones), an earth problem, or +12v problem. either way it seems to be a degenerative thing, it doesnt die immediately, just gets progressively worse.
