valvetronic motor/acutator replacement

Need a new valvetronic motor/servo valve actuator (11377548387). The motor often triggers the check-engine light and the EML light frequently, accompanied by the car going into limp mode - revving past 4/5 RPM seems to get it out of it.

I have a 2007 BMW Z4 2.0i (E85 roadster with the N46B20 engine). Just wondered if OEM is worth it here (https://shop.parks.uk.com/products/bmw- ... 1377548387) or would something cheap aftermarket one off eBay would do the job (https://www.ebay.co.uk/sch/i.html?_nkw= ... m570.l1313) ?

I've read that when doing this you need to be careful of the eccentric shaft sensor. Probably also worth replacing the valvetronic motor gasket/O-ring as well to prevent leaks.

Any ideas in terms of parts and where to take this to get this done? live in Gloucestershire.

Cheers
