I still remember Pierburg from my time in Germany where they are know for large scale manufacturing of automotive parts, particularly fuel pumps as I recall. This Intake Manifold Shut Off Motor is in high demand as a replacement part on Mercedes 6cyl. diesel engines. It is often the culprit when the car has gone into limp mode. I ordered this part and repaired the fault myself after researching on the net. I saved myself a large amount of money. The item is identical with the original and the fit was perfect. The plastic clips that connect the motor to the linkages I purchased from Mercedes for AUD $10 as I couldn't find them elsewhere. Pricing of the part was great and even the postage from the US was reasonable. Full tracking was provided and I had the item at my door in Australia in less than 2 weeks. Very happy!
