2003 vw beetle 1.6 cabriolet door actuator

hi,

I cannot open the passenger door on my 2003 VW Beetle 1.6 CABRIOLET



Local garage told me the actuator/central locking needs replacing. I said I would try and source the part myself rather than thru dealership, which seemed so expensive and came across your site,

I think the part is: B2837015AE, but various sellers are giving me differing accounts as to its compatibilty.

I have tried putting my vin number on some parts sites, but it doesnt seem to be recognised and so cannot verify. I need to take the car into the garage for them to get the door open and reach the part, but I am hoping to track down the actual part number i need, so that they can then insert the new one.
Can anyone help me?

Thanks so much
