Re: Knock sensor fault.
I have recently (less than 1000 miles) purchased and fitted a new Bosch knock sensor for mine as part of the fault finding process but it still won't cancel the error code.
I'm going to put the old sensor back in tonight and see if it makes any difference - if it doesn't I could sell you the new one for £40 - or is this against AO rules ? The new one was £59 something from Fuel Parts via Partco, I have the receipt. I'll get the Bosch number off it if you're interested.
