Itâs very âhit and missâ
And you have to hit the right part. Plus it all depends on the problem being the brushes stuck in their holders in the first place, if thatâs not the problem then hitting itâs not the cure.
It can work for an hour, a hundred metres permanently or a couple of days.
Thatâs the thing, it costs nothing to try so what have you got to lose.
Have you had diagnostics plugged in ? What was the fault code ?
P.S, itâs more of a âjarring thudâ thatâs required, rather than a âhitâ
