The honest pitch
What this actually does to your E63 S
The W213 E63 S has all the noise of the C63 plus an extra metre of wheelbase to bounce it down. AMG's stock valve map is conservative — Open Valve simply pins the flaps wide.

Long read
The Mercedes-AMG E63 S valve story
The W213 E63 S has all the noise of the C63 plus an extra metre of wheelbase to bounce it down. The valve map is similarly conservative — the M177 V8 only really opens up in Sport+ under load. The estate variant (S213) is especially under-served by the factory programming.
Open Valve pins both rear flaps open. W213 saloon and S213 estate both supported with the same two-module kit.
Underbody access required — workshop fitment via a lift recommended. About twenty-five minutes.
Install — step by step

- 03
Disconnect both valve actuator connectors. Plug each module inline.
- 04

- 05
Refit underbody.
- 06
Pair fob, test.

Mercedes-AMG E63 S — FAQ
Saloon and estate both supported?+
Yes — same kit.
What about non-S E63?+
Yes — both E63 and E63 S use the same actuator.
Will it throw a warning light on the dash?+
No. The module sits in the signal path between the ECU and the actuator motor. The ECU sees a normal actuator response back, so there's nothing to flag. We've shipped thousands of these and not had a single check-engine call linked to the module itself.
Is it reversible?+
Yes, fully. Unplug the module, plug the OEM connectors back into each other, refit the trim — about three minutes' work. There's no permanent change to the car, no part cut, nothing in the ECU. Dealer service visits, MOT, sale to a new owner — pull it out and it's like it was never fitted.
Does it work with an aftermarket exhaust?+
If the aftermarket back-box retains the OEM-pattern valve actuators (most do — Akrapovic, Milltek, IPE, Capristo all run the factory motors), yes. If the system is a straight-through with no valves, there's nothing for the module to override.
Does AMG Drive Pilot need disabling?+
No — Drive Pilot continues to function normally with the module fitted.
Will MOT pass?+
UK MOT noise testing is subjective. Stock back-box held open generally passes. Sold for off-road use.
