Engine management light

Got a 1.5dci k12. When I start the car up and drive for about 10 mins or so everything is fine, I can put the accelerator down quite hard and it will pull quite well. But then after that if I do the same the red engine management light comes on the dashboard and a message on the radio display saying engine system fault if I ease off the accelerator the light turns off.

It will only let me get up to about 3000rpm then it won't go past that and stays at that speed, then the light comes on. Any ideas Thanks Stu😁
 
Sounds like the "limp mode" that some cars have, something's broken and the car is stopping you driving it in a way that could break it more

Given that it's not doing that when things are cold, you can be pretty sure the thing that's failed only stops working once it's at temperature, perhaps some sort of exhaust sensor at a guess but honestly the only way to know for sure is to plug it in and get diagnostics done.
 
Probably need to clean egr valve intake and maybe manifold.

Edit :- These are most likely blocked with carbon does not mean this will solve your problem but is a good idea to try this in a dci as it will give a lot of power back if it is lacking.
Its worth checking out.

Cheers Sparky, well my uncle's a mechanic I'll give him a call tomorrow and get the car to him hopefully it can get resolved.

I would get the codes and go from there, could be many things...
