Engine system fault

Disco41989 · Sep 12, 2019

Hi everyone I’m wondering if anyone could possibly help me. Bought a 2012 discovery 4, 6 months ago. 100k miles on the clock and recently had a new timing belt and mass air flow sensor fixed. Fast forward to now, I keep getting an engine system fault. Car goes limp and is hard work for it to pull off, although after that seems relatively fine. 9 times out of 10, if I restart the car, the fault clears and I can drive normally. But this week it’s been happening every day, numerous times. It’s being looked at finally on Saturday, but just wanted to see if anyone had had this issue before, or could shine a light on what it could possibly be?

also, this may be related or it may not, since I’ve been getting the engine system fault, car won’t shift into sport mode.

thanks in advance for anyone’s help

Welcome

I'm not sure but I don't think the Discovery 4 ever had a 300TDi engine fitted to it

Try asking in here

You might have a fault on an ABS, ESP type traction stability sensor. If such a sensor is misbehaving the computer decides it may not be able to take control of the traction stability in the event of you hitting a slippery surface such as mud, gravel, ice etc. For safety reasons it puts the engine in to limp home mode to reduce the risk of you hitting such a surface at speed.
