Did anyone have any thoughts on this?
I too have the second of these noises - i.e. a low pitched moan/groan when engine under load between 2000 and 3000 rpm. This is also accompanied by a mild vibration coming up through the pedals, drivers footwell, bulkhead. This is not really noticeable below 1900/2000 rpm and above 3000 rpm.
Am going to get the fluids changed (gearbox, transfer box, front diff) to see if that helps - probably worth it anyway on a 07MY TDV8 (ZF 'box I think?) at 57k miles, no?
There also seems to be a bit of a "bump/thump" when changing from 1st to 2nd under medium to high throttle and another that sometimes happens when you are accelerating under medium throttle and then lift close to the gear change point.
Also, just occasionally, the gear changes seem a little random/non-linear, almost exclusively under medium or low throttle settings - i.e. doesn't step down for a few secs with 60/70% throttle input when at low revs in a high gear or changes down then up again within a short space of time. Almost as if the 'box doesn't know what gear it should be in / getting a bit confused. Sometimes also get this "confusion" after a period of spirited driving with large throttle openings followed by total lift off followed by large throttle opening when in "D" as opposed to "S".
Thoughts so far are:
1. All above are normal behaviour, not to worry.
2. Gearbox, transfer box or front diff on the way out
3. Trans fluids need changing
4. I have only done circa 5k miles in the car - maybe the 'box is still "learining" my driving style, which may be different from the previous owner's
Any help/guidance/thoughts/observations on the above much appreciated!!
Thanks in advance! -----------------------------------------------
