Hello sir.

My vehicle listed above kdj150 is showing me check engine and 4lo light after I drive it for about 70kms. I got it diagnosed and it showed me p0191, p0299 and c1452. My mechanic suggested changing the step motor for turbo as it had a glitch according to his test results, and we changed. The vehicle drove well for a good 150km and power was restored but then suddenly it lost power and the engine light and 4Lo started blinking again. I tried removing battery terminals and resetting the memory, so the lights went off, but the car was now moving at 100km/h at 3000rpm which is not normal to me.

I am now confused about what more to do on this vehicle and here I am asking for your expert advice.

Regards,
Noor

It sounds like the car is in limp mode, we need to re-run the codes to see what comes up. This guide can help, I would perform a CAN scan, you can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:

Please go over these guides and get back to us.
