Running techron on a DI car won't help
Running techron on a DI car won't help as no fuel passes over the valves.
Past time for the Walnut Blast.
The DI cars have a design flaw the causes carbon build up over the valves.
No fuel passes over the valves. This is not unique to BMW.
I have a feeling that figure is off by an order of magnitude.
