Despite a day using Mr Muscle neither the carbon or the aluminium has dissolved
in fact my three day assault on the cooler section has done nothing: the EGR code was back in just a few miles.
Fortunately that gap allowed it to pass through the MOT as the fault light has to be on throughout the testing to be a fail.
It doesn’t affect the car but it does irritate that I can’t fix it other than buying a new item at probably 20% of the value of the car.
