Terms & Conditions

 Please ensure before ordering an ECU that the fault with your car is an ECU fault and your problem has not been misdiagnosed, if we supply a faulty ECU we are happy to provide a replacement or fully refund you if a replacement is unavailable, however if your existing problem persists with your car then the fault will have been misdiagnosed – if you request a refund on this basis then a 20% restocking fee will be deducted from your refund & return postage will be at purchasers expense.

Advice on ECU Diagnosis & replacement

1 – Scan the vehicle with a diagnostic scanner & record fault codes – rectify any faults recorded here first & check the wiring for faults.

2 – If your ECU has ‘No communication’ with a diagnostic scanner it is essential that you check relevant fuses and consult a wiring diagram for your vehicle and verify the power supply & test the wiring to your ECU – particularly test power supply relays (Engine control relay). – ECU’s returned due to misdiagnosis are subject to a 20% restocking charge.

3 – If you are not a qualified / experienced auto electrician or garage technician and you are unsure if the problem with your car is the ECU then please consult one first before ordering – there is a 20% restocking charge for returns due to misdiagnosis.

4 – If your fault is a cylinder misfire please check spark plugs / leads / coil / injectors and wiring faults / headgasket faults etc before ordering, if these have been checked or replaced then it is important to check inlet manifolds for leaks, engine compression & perform a vacuum gauge test to check for valve problems.
