Fume Smell in Cabin and Glow Plug Supply From Relay 4159
I have a problem with my mini which is currently preventing me from driving it.
There is a terrible smell of what I believe to be exhaust fumes in the cabin. Itís so bad within 30 seconds of driving the car that your eyes burn and you feel faint - hence not driving it! The smell is also very apparent outside of the car.
I took it to an independent to diagnose, but they didnít have much luck.
One thing they found for sure was code 4159 - glow plug supply from relay. This would suggest perhaps that the glow plug relay is out? Iíve seen this quite cheap on eBay, so if someone could point me in the right direction, this one should be an easy fix.
Now onto the smell issue. The DPF is definitely not blocked. Real-time data shows that there is only 5.9 grams of particulate mass in the particulate filter, and there is no fault code for the DPF, or engine warning light.
The garage seem to think that a leaking turbo is the cause of the smell. They believe it to be soot, not oil, however there is nothing visually which would suggest this. Theyíre not confident enough in their diagnosis to carry out the work either, so was looking for some opinion on what anyone this the cause could be.
Definitely not a cracked or leaking exhaust, has been checked by these guys and an exhaust centre.
Thanks in advance! Images attached of the turbo surround.
