I've got a strange issue and I'm planning on taking my car (C5 X7 2.0 HDI) to a local dealership so they can have a look on it, but meanwhile I was wondering if anyone had any idea what the issue might be related to. It does not happen very often, but every now and again, while reversing, the whole car starts shaking and the revs drop to maybe 5-600 rpm? However, if I'll quickly switch it back to D and then to R again, the issue seems to go away, and the revs are as they should be. So far, I had someone else's thought on it and recommended checking the glow plugs. The current mileage is roughly 175.000 Miles/ 282.000 KM, owning the car since the mileage was as low as 87.000 miles/ 140.000 KM and I have never replaced them. So, any ideas? Many thanks!
