Hello, I have noticed a rumbling coming from the rest of my kodiaq when accelerating especially when the revs get to about 2000rpm through to just before 3000rpm this is especially loud when on the motorway and you put your foot down to overtake and the box downshifts. After 3000rpm it seems to quieten down and if it gearshifts in that rev range the sound will also quieten down. Car drives lovely other than that and has no clunks or rattles at all. It's had all fluids changed in the last 2 years at Skoda. I had my local mechanic taken a look at the prop and bushings and he said they looked fine.

UPDATE!

Had a vag specialist to diagnose the noise and he put it down to the tyres on the rear. Swapped the tyres from front to back and the noise disappeared. Perrelli scorpion verdi now on rear and continental conti-tact on the front. Can't believe tyres can make that much noise at certain rev ranges and then not make a noise after that but you live and learn. Continental conti-tact were the ones making the horrible noise on the rear

Beware these Pirellis too. I have had previoulsy 3 sets of Scorpion Verdes and they all started to make noise when the wear markings were almost reached. Probably made on puropse.

Thanks Linni for that, the garage did say that all 4 tyres will need replacing soon as they are 4mm. I wonder if the tyre manufacturers are making the tyres make the noises when they are low. Does anyone have any recommendations on tyres?

As I am running on 20 inch wheels and the tyre wear on these is enourmous (some Michelins lasted only 17 000 km) I have stopped on Barum Bravuris 5 HM (high mileage). Pretty quiet, very good in rain and they last about 60 000 km. But I am sure there are lots of options available.

@woodyvw How many miles was it 2 years ago?

They never renewed the Rear Diff oil when doing the Haldex (all the fluids) did they?

So is it a DQ500 or a DQ381 DSG your car has & what was the mileage when the oil & filter was changed?

Hi @ootohere All fluids (haldex and gearbox) were done at main dealer at 41,772miles and the car has just passed 56000miles. I have no idea what gearbox it has, how can you tell? I have the 190bhp diesel engine 4x4 7speed dsg

OK. So Haldex and DSG were done.

Not the rear axle / diff, some people launch boats / jet skis with AWD,s. Hence some change Diff Oil.

(& Fluids are also Coolant & Brake Fluid.)

Yes had cam belt and water pump and brake fluid done at the same time, I brought the car 18 months ago. I can't find anything to say that the rear axle/diff have had a oil change. I have had the haldex pump checked and there was a tiny build up on the gauze but that has been cleared off.
