I have got a 1.9d felicia engine code AEF. will a front sensor from any other vw or skoda fit cheers.

Not sure, I think they may be specific to the skoda, how much have you been quoted for a new one?

£50 plus vat,i can get a rear one cheaper from £5 to £20. i cant understand the price difference, surely the only difference is the cable lengh.

50 large plus vat is Cheap for an abs sensor, some are tripple that price.

I managed to get one from local motor factors for £48 inc vat so not to bad.
