0B5 DL501 S-Tronic TCU replacement
12-month warranty2–5 day turnaroundTracked return deliveryData transfer included
A brand-new 0B5 DL501 S-Tronic TCU, fitted to Audi and Porsche models. Listed under part number 0B5927156D. 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.
Not sure the TCU 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 TCU fit?
This unit is used across Audi and 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.
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.
Will the warning light go out after the work?
Yes, once the unit is refitted and the stored codes are cleared, provided the fault was in this unit. If a related wiring or sensor fault is also present it has to be fixed separately — we tell you what we found.

How It Works
- Place your order online — add the service you need to your basket. Before the item is added we ask for your vehicle details and fault codes, so we know exactly what we are working on.
- Send us your unit — replacements are supplied on an exchange basis, so we need your original unit to transfer its coding data. Prefer to program the new unit yourself? Order first and send your original afterwards.
- We do our part — we transfer your data to the new unit and test it, usually within 2–5 working days.
- Tracked return delivery — by DHL Express or DPD, ready for installation.
