You are purchasing an EXCHANGE SERVICE product, upon receipt of the ECU/ DME Set in our office, we will diagnose, program and replace your defective M535 Porsche Immobilizer CLU control unit.

As always, once we finish programming and exchanging your Immobilizer, we will proceed to test it in our dedicated tester vehicles ensuring you receive a Plug and play set, Guaranteed!

Porsche installed the 996 immobilizer/ M535 immobilizer CLU (Central locking Unit/ Immobilizer) in a vulnerable location under the driver's seat, making it prone to water damage. Leaving the convertible top open during heavy rain, clogged rain drains, or bad sunroof seals will flood the car interior and sadly the first thing that goes bad is the M535 Immobilizer Central locking unit CLU.

Once the CLU gets wet, there is no reliable way to clean it as the corrosion will start immediately and eventually the system will stop working.

This severe damage will cost hundreds or even thousands of dollars to correct at the dealership.

WE CAN HELP YOU! Our exchange service will get you back on the road saving you hundreds of dollars. We will provide you with a Brand-new Immobilizer unit "Never Wet" and we will exhaust all possibilities to save the programming of your remotes.

We can also provide you with new remotes and Key cut service. Take advantage of the best service available.

We include a bottle of DeoxIT D-Series to clean any corrosion on the Immobilizer harness connector.
