Perhaps this is true for the non turbo Canadian B's. As my turbo has full length underbody panelling. To get to just about anything under the car, the underbody panelling must be removed. That's why I went with an oil extractor. Otherwise, I would just creep under the car like all my other vehicles. I thought that all B's had this, but maybe not. Even the rear suspension parts have their own cladding.Same here. No panels to remove for oil drain (sump) plug. 2.0 gas/petrol engine though - but I doubt you need to remove panels for the diesel.
