Nissan X Trail Clutch issue when reversing.

[nigxl]

Car is nearly 3 years old with 30K miles. It's the 1.6 DCI 130 bhp lump with selectable 4WD.
So a month left of warranty I decided to get a niggle sorted out.
When reversing uphill I get an awful groaning sort of noise which begins as the clutch engages and continues until I reduce throttle or press the clutch again.
Initially Nissan had the car in and changed an upper engine mount which did nothing as expected.
Now they are saying it is a characteristic of the car ???
Clutch is also smelling pretty bad, but apparently that's normal too ???
I'm tempted to take it to another dealership which is a 2 hour round trip for me which is fine if it can get sorted but so far the car has been in 3 times to the local dealer and I'm just getting fobbed off.
Anyone heard of this issue before on the T32 X Trail Diesel before?
Thanks

What are you doing in reverse that's different to when going forwards? Have you ever set off up such a steep slope going forwards?

Nothing at all, it seems fine in forward gear.

The gearing in reverse is probably not the same as first gear, so you might need more torque to pull away. That would put more load on the clutch and gearbox, and generate more heat.

If you slip the clutch it will smell, the difference is when going backwards the smell comes up over the bonnet and in the air vents and not left behind.

It won't smell if you are not slipping it to get it hot. Many people who say 'doesn't happen when im going forwards' neglect the fact they reverse slower and often slip the clutch when going forwards they don't.
