    Does anyone have one they wish to sell?

    It has to be off an early car, with the square connector, not the later D-shaped one, which is shared with the S4.

    So, from a 30V up to '98.

    It fits into the transmission, as opposed to the 12V version, which bolts to the block. I need the one that reads the flywheel puls ring, not the one that reads the flywheel ring gear (rpm sender).

    Thanks.

    why does it have to specifically be from that car?

    Surely any sensor with the old style plug will work, as long as its long enough to reach the trigger wheel. Its quite a simple VR sensor, not really anything fancy.

    I've not seen anyone on here breaking a 30v either, so you might be struggling!

    Is that the sensor you've discovered you need for the V8? I was wondering what sensor i'd need to use for mine just recently.

    It has to be from the B5 2,8 30V, up to 1998. You can't use any old sensor, if the air gap is wrong. Seeing as there were no manual S8's sold in the UK, that's the next option.

    The sensor fitted to the 2,8 30V from 1998 onwards, is the exact same item fitted to the S4 and RS4, and has the D-shaped plug, so no good. The sensor on my old 2,6 V6 is bolted to a bracket on the block, and while it ran the car by me just poking it into the transmission hole (it's also too long) the car splutters and pops, as with the engine running, the sensor's jumping in and out of the recess.

    Guess I may have to order one new.

    If you see the way it fits, you'll realise it's not worth the time.

    You'll also have to cut a chunk out of the engine block, and probably the transmission. At £40.25 new for the proper item, it becomes pointless.

    Messing around with air gaps etc on a conversion isn't worth the effort - if you have running issues, you'll be hard pressed to work out if the sensor gap is wrong, or something else at fault. It's also not easy to reach to mess around with, with the engine in situ.

    Ye i hear ya. I just figured they'd be a lot more expensive than £40!

    On mine, it looks like the sensor is going to end up sat half way between the adaptor plate and the Rover bellhousing, which might prove rather interesting!

    Lol. I expected to hear it was £90+.

    I've ordered one, will be with me tomorrow or Wednesday. Can't wait to complete - chauffeur driven Limo's don't do it for me.
