Recall of Minis

[montyracing2]

I don't think I'm thick but can someone tell me what this means in a way I can understand (its about a process within the mini engine):

A Mini spokeswoman said: "The turbocharged engine of the Cooper S and John Cooper Works engines is equipped with an additional water pump which draws residual heat out of the turbocharger after the engine has been switched off, to prevent carbon build-up of the oil in the bearing.

"Under high operating temperatures an electro-migration can occur at the circuit board installed in the additional water pump.

"The electro-migration is caused by plastic additives in conjunction with high temperatures and can lead to a failure of the additional water pump."


Thanks - MR2

"Looks like yer pump's clogged, mate. Corrr, I dunno. About £200 to sort it, I reckon."

Interesting - where have the plastic 'additives' come from?
