Knock sensors - where can I get 'em?

[Ahmedsinc 414]

Hi guys. Courtesy of Repco being a hopeless bunch of muppets I'm still in the hunt for a new pair of knock sensors to suit an E36 325i. Would prefer to stay away from the franchise BMW dealers as I don't have a first born son to sell to pay their prices.

While I'm thinking of it, has anyone here tried the generic OBD fault code readers from Repco? Any good or should I save my money and take it to a workshop with GT1 instead?

Cheers all

Depending on your location you could bring it to us for a complimentry diagnostic. If needed we have knock sensors at the lowest prices.
