ECU / Engine Warning Light

Without a functioning engine it's going to prove very difficult to get from A to B. If your engine light is shining bright it'll likely be accompanied by a lack of power as your engine management system enters 'limp' or 'safe' mode to protect itself.
In many cases the engine light on your dashboard is lit up due to something small such as a faulty sensor but it could be a larger mechanical issue. Either way get a trained professional to look at your engine at the earliest available opportunity. Continuing to drive with the light on could be causing significant damage with every additional mile. If you are in need of an affordable replacement engine part click  here for a low cost solution.

Battery Warning Light

Don't be alarmed if you see the battery warning light when you turn your car on as this is normal. However, if it still visible after your engine has been on for a few seconds there may be a fault with the electrical system in your car. 
The cause of this can include something simple to repair such as damaged cabling or a bad connection but may also be attributed to a faulty battery or alternator. If the problem is with your alternator you will run out of juice and come to a stand still as you run out of electrical power.
