Hi I have a toyota auris 2014 1.4D and its gone in to limp mode with the engine management and traction control light on.
After plugging in an OBD I get the fault "P0299" turbo/supercharger underboost. I have had It in a local garage who said the turbo sensor was dirty and he cleaned it but the fault was still there and said the turbo seemed like it was blocked Any ideas?
There doesn't seem to be any boost leaks I've had a recent service and run it on asda Diesel.
