Hi there, I recently purchased a 2009 Land Rover freelander 2 td4 hse with 130000kms on the clock.. Now the engine light has come on and stayed on, there's black smoke coming out the exhaust when I accelerate and I've checked the fault codes and they are as follows: 1/ P0380 glow plug/ heater circuit A. 2/ P068b ECM/PCM power relay de energised too late. 3/ P0299 turbocharger/supercharger A underboost condition.. Car is driving fine but is making a humming almost rattling sound and just isn't sounding the healthiest.. Any ideas what could be the problem? Does it sound major/expensive? Thanks in advance!
My car has 70000 miles.
My car has an automatic transmission.

The glow plug faults are most likely going to cause a hard start condition, which will be most noticeable when the engine is cold. The colder the engine, the more difficult it would be to start usually. Often times, glow plug failures aren’t noticed until it winter time. The relay fault is saying that there is a problem with the ECM relay, likely that the relay is staying on too long, which will need to be diagnosed. As far as your black smoke and bad noises, the underboost fault is the most likely cause of these issues. It could simply be a boost leak, which would cause a rich fuel mixture, resulting in black smoke and low power, or it could be a failing turbocharger, which would result in low power and black smoke as well. These are not the only two possibilities, simply the most likely. To find out for sure, you would need to have a qualified technician, such as one from YourMechanic, come to you and diagnose the check engine light and the smoke from tailpipe, after which they will be able to suggest an appropriate repair.
