Rover Lucas 16CU Engine ECU Repairs

Type: Lucas
Fits: Jaguar XJS / XJ12 / Rover
Fuel: Petrol

Note: This ECU may also fit other models.

A Lucas 16CU petrol engine ECU gets repaired under our own UK roof. Jaguar or Rover, your ECU follows one route here: test, then quote, then work once you say so.

You may have reached this page with DAC 6336 to hand, or a label reading Lucas 16CU. A different number does not rule you out. Our technical team answer for coverage on each specific unit, without a guess.

Rover owners will find more under Rover engine ECU repairs.

DAC 6336: mostly Jaguar, also Rover

DAC 6336 mostly fits Jaguar. Sellers list it for a Jaguar XJS and a Jaguar XJ12, each at 5.3 litres.

It also fits Rover. On either make, the fuel is petrol, and the make alters nothing in the bench work below.

A seller’s line, on either make, says nothing about the state of your ECU. Testing answers that.

The same bench work for Jaguar and Rover ECUs

Engine ECUs form our specialism. You post it in from your UK address, whether you own the car or run the garage. We take no walk-ins. We log it, then inspect it visually and after that test it electrically, before diagnostics aimed at its particular fault.

Those diagnostics aim to find the failed part. Dry joints sit alongside voltage regulator faults and injector driver faults as possibilities. Your ECU’s own tests show what it actually has.

Then comes the outcome, quote included. You see our findings before deciding. Your authorisation is what releases chargeable work.

From our bench back to your car

Our engineers then put right the failed component themselves, with equipment we hold in-house. Their bench has a microscope, plus rework gear with temperature control. No overseas processor or subcontractor handles it. Only final testing, once passed, completes the repair. Jaguar unit or Rover unit, that final test is the same.

You get back your own ECU, never a swapped one. Plug and play sums up refitting to your Jaguar or Rover. Recoding does not arise, since our repair preserves the original coding. Warranty lasts 24 months, non-transferable, tied to that exact repair.
