Porsche S-Tronic Mechatronic DSG DL501 replacement
12-month warranty2–5 day turnaroundTracked return deliveryData transfer included
A brand-new Porsche S-Tronic Mechatronic DSG DL501. Listed under part numbers 0B5927256F and 0B5927156K. Every unit is tested before dispatch and the price includes data transfer: your original unit must be sent in so we can copy its coding and adaptation data across, which is what lets the new one work in your car without a dealer visit. Replacement units carry a 12-month warranty and normally leave us within 2–5 working days.
Mechatronic units need basic settings and clutch adaptation with a diagnostic tool once refitted — that applies whether the unit was repaired or replaced. Any competent transmission specialist can do it; we tell you exactly what is needed with the unit.
Not sure the mechatronic is the cause? The symptoms and the fault codes we see on this unit are listed under Common Faults. If your codes differ, send them over before ordering — if the unit turns out not to be faulty you only pay the test fee and return postage.
Which vehicles does this mechatronic fit?
This unit is used across Porsche. Check your exact model and year under Matching Vehicles, or compare the number printed on your own unit with the part numbers listed on this page. The same hardware often appears under several part numbers — call 01884 798090 if yours is not shown.
Prefer not to remove the unit yourself?
Choose the on-site option and bring the vehicle to our workshop in Uffculme, Devon. We remove, refit and road-test it before you drive away, usually the same day.

Frequently asked questions
Do I still have to send my old unit in?
Yes. A replacement unit has to be matched to your car, so your original is needed for the data transfer — we copy its coding and adaptation data onto the new unit before it ships.
How long will I be without the unit?
We aim to complete all repairs within 2–5 working days. Should a repair take longer, we will contact you with an update. It goes back to you on a tracked service. Ask about on-site fitting if you need the car back the same day.
My part number isn’t in the list — can you still help?
Usually yes. The same hardware appears under many part numbers. Send us a photo of the label or call 01884 798090 and we’ll confirm before you send anything.
What warranty do I get?
Replacement units carry a 12-month warranty. See Returns & Warranty for the full terms.
Does it need setting up after fitting?
Yes — basic settings and clutch adaptation have to be carried out with a diagnostic tool once the unit is back in the car. Fresh transmission fluid and a filter are strongly recommended at the same time.
