Land Rover ECU 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 year Land rover Disco cars. your best bet is to match the part number up with the unit you are replacing. This unit has a bit of external corrosion on the case because this was from a New-Hampshire car (that state heavily and pointlessly salts their roads) however it in no way affects it's operation or future interegity, just cosmetically. I just felt I should mention it. I even inspected it internally and it's good to go.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!
