Acceleration issues in my 2013 Range Rover Evoque SD4

While driving, I noticed that when pressing on the accelerator of my 2013 Range Rover Evoque SD4 there was no power. I pulled over and switched off the engine and, after a few minutes, tried restarting it. It would crank but not start.

A diagnostic scan picked up 'Camshaft and Crankshaft Correlation' and, when inspecting the cam belt I noticed that a part of it was smooth with the belt teeth broken off. I then changed the belt and tensioners and tried starting again with the same result; cranking but no start. I have so far changed the diesel filter, bled the fuel lines ensuring no air and replaced the battery but the car still cranks and will not start. The vehicle is a 2.2-litre diesel auto.

The reason the scan threw up a camshaft phasing problem is because the belt has stripped and allowed the camshaft timing to become way out of synch. This is also why the engine lost power and wouldn’t restart in the first place.

Simply replacing the timing belt won’t fix it, as the engine’s original camshaft timing has to be restored for the engine to ever fire again. There’s a specific method to do this, but pretty much any mechanic will be able to retime the camshaft and get you going again.

If the engine is retimed and still won’t fire, there’s a chance the stripped belt has allowed internal damage to the engine which may need a full rebuild. You could be looking at bent valves, cracked pistons and more.
