Land Rover ECU 

80801 A ECU MKC 104620 GEMS8

Up for sale is a Working, in excellent condition Land rover Discovery Engine Computer / ECU. Part numbers listed at top . My list shows this fits many 97 98 99 year Land rover Disco cars. your best bet is to match the part number up with the unit you are replacing. Physically & cosmetically very nice, very little external rust on the case. These can commonly get very rusty due to their position in the engine bay.  If the case gets significant corrosion, it will eventually stop functioning. This may need to be programed at the rover dealership with your cars immobilizer code before it will start with this ECU.A faulty ECU is one of the primary causes of false check engine lights, intermittent no start or random cut out. Sometimes these will lose injector pulse (no fuel injector function / no start). They also sometimes lose the fuel pump relay turn on mosfet, which is a pretty common issue with these, among others. Price this at a dealer, and you will buy from me... You will be shocked at the price. This comes with a 30 day warranty. These units are very hard to find!
