tr Volvo 240 ECU Up for sale is a Working, in excellent condition Volvo 240 ECU - Lambda sound control unit. From a 1981 model year car, may fit more. Part numbers listed at top. Should fit other models of the same vintage as well, but it is the buyers responsibility to find this out. As always your best bet is to match the part numbers with the part you need. A faulty ECU can cause a whole hots of issues with these cars, including non running, and random cutting out (but usually it will re-start moments later). Also idle control & emission issues are possible (excess smoke or overheating caused by lean running). Hot or cold start issues can be caused as well. These units are no longer available almost everywhere and VERY hard to find used. If you can find a new one, they are usually in the $500+ range. Ouch, not here! This comes with a 30 day warranty.
