The diagnostics shows that the cats are blocked so the engine light stays on,but car is running fine.
Garages tells me the only why is to leaf it in and to remap the computer so the computer dos not pic up the cat sensors
Any advice??

I took it to AutoZone so they could check it,the reading say it the camshaft position sensors.the diagnostic codes reads 0016,0017.

When check, it reads, camshaft position sensors. Check engine light stays on

When coming to a complete stop, the car makes a thumping noise. When driving off from a stop, the car studders. No power loss but a hesitation. Also when turning at low speeds, it feels like the old 4x4 shakes. Could this be tire sensors for the 4matic going bad? Check engine light just came on.

How will I know which I need, the standard of HID?

After the car warms up you can smell (hot) from the drivers door back to the end of the car. All fluid levels are up, no flashing code or engine lights. Car still runs fine but you do have the hot smell. No visible leaks under the car.
