Finally got to the bottom of these rumbling noises from the rear of the car. Despite several visits to the dealer no faults were found until 3 weeks ago by which time the noise had become very obvious. Technician heard it straight away and asked me to book the car in. They diagnosed fault with the rear differential and and Skoda UK agreed that the diff should be replaced. After the work was done I was told that one or more of the Haldex clutch plates had disintegrated and debris was being moved around inside the diff. The car is now smooth as silk and seems to perform better though that may be my imagination. It has taken two years for this problem to be diagnosed and repaired, involving repeated visits to the dealer as well as concern about the safety of the car. At least the car was within warranty so no cost to me other than 12 mile round trips and numerous hours trying to get it sorted. I suspect that the diff was faulty from the factory. The car has still only done 13000 miles so should not have gone in such a short time.

In reply to your suggestions - the rumble normally happens when pulling off on a slope and turning at the same time. However I've occasionally noticed it when moving off straight ahead or reversing. Once the car is on the move it drives smoothly on a good road without any rumbles, bumps or clonks, though the ride is hard and it does tend to respond harshly on rough roads). One of the problems for the dealer trying to diagnose it is that it doesn't happen all the time and it's hard to find locations where it can be demonstrated on demand. If this is a normal effect of the 4wd I would have thought other Yeti 4wd owners would have noticed it. Thanks again for your suggestions. I'll keep monitoring it and see whether it develops.

Thanks for those suggestions. The car has just had its 24 month service at my local Skoda dealer. They have checked all components under the car which might cause the noise but have not found any faults. They made the usual comment when they can't explain a noise : a) they can't hear it; and come back if it gets worse. I had a friend who used to work on Landrovers test it yesterday. He can hear the noise (a rumble from the rear when driving off from standstill, especially on a slope with the steering turned) and suggests it could be one of the rear wheels lifting under load causing the ABS system to operate on that wheel. He made the point that as the tyres wear down they lose some of their grip and so the wheel which is least under load starts to spin which prompts the ABS to correct it. Any further comments appreciated!

I have a 2014 Yeti Outdoor 4x4 automatic. For some time it has been making a rumbling noise from the rear of the car from a standing start. It is particularly noticeable when the steering is on right lock and also when on a slope. This happens on normal tarmac. Sometimes this is followed by a distinct "bump" sound as the car changes into 2nd gear. I've had the car tested by my local dealer on two occasions but they can't find a fault nor can they detect a noise (of course they have not tested it in the places where it usually makes the noise). The car did not do this in the first year I had it (from new). Has anyone experienced anything similar?

Thanks for those suggestions. It has been like this from new (8 months ago) I wondered whether it was programmed to do this but the manual states that the washers should come on before the wipers.

The Wipers on my 2.0 litre DSG Yeti give 4 wipes before the washers begin to work. How can I reset them so that the washers come on before the wipers?
