Important! – Please read! - It is essential before ordering an item that the part number of the item you are ordering matches the part number EXACTLY of the component on your car that you need to replace. Also ensure that the fault with your car is an ECU fault and your problem has not been misdiagnosed. We strongly recommend having your car diagnosed by a competent Auto-electrician or specialist garage before ordering. 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 has most probably 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.
