I've got a haldex controller I'm planning on fitting but have realised that the "new" controller is the flat gasket type where as the old one is the one with the rubber o ring looking at part number the last letter are different both are from a s3 is there any reason why it won't fit or would it just be a case of a revised part anyone come across this when changing there's ?
 
I think they depend on if the car has esp or not. I believe the one with o-rings in non-esp and the gasket one is esp. Don't hold me on that though

Spoke to a parts place today and you are correct 02D900554B (with o rings) is non esp and 02D900554c and 02D900554D are esp and these two are interchangeable and look identical

Can the haldex be changed on axle stands or will you need more room

I don't see why you couldn't change it on axle stands, just get it as high as possible and get some help.

Yeah easily. I changed the whole rear end on axle stands. Changing the Haldex controller is fairly simple if I remember correctly

There's a guide on VW Vortex to rewiring the plugs

Right according to parts for German cars my chassis number says I should have haldex part number 02d900554d (which I bought) but vag com tells me my current haldex unit is 02d900554b which I'm told is the early non esp model so my question is would this be why I never had 4wd If it's the wrong one and how can tell which one I should have
