Seems the rear wheel bearing noise is likely to be the tyres, but waiting for more dealer investigation. Still does a good mpg and speeds.

It is a great response car, so glad I have the diesel version. 30+mpg when used for response and still around 49mpg overall (49.2 last 10,0000 miles)

After Tom_Vrs post I checked my rear tyres (put my key in the threads and checked depth). And the wear is deffo uneven. Same applies to inner side of both rear tyres. Based on that I booked 4-wheel alignment measuring & adjustment for this friday. I guess we'll see after that. My neighbor is manager for a local garage that has rights for skoda & vw warranty repairs. "Suprisingly" I always get 1st class treatment. They have also been running specialised rally & track racing teams with VAG products.. so they know their stuff! If there's something wrong, they'll find out. I'll keep you posted on what happens.

My car is equipped with dsg so I have no reason to suspect anything clutch related as the dsg is seemingly working like a charm.

Just a quick update: I have been contacted by my dealer to say Skoda have requested they have my car back in to the dealership again so they can take even more information/readings from the ECU/engine, still no fix mentioned though.

On the flip side since I removed the offending plastic lid that was stuck in the engine "nothing to do with the dealership who serviced it, honest guvnor it wasnt there when we had it, never seen it before etc, etc." the car is running a lot smoother and apart from the vibration at 1500rpm it is almost as it once was.

Will let you know if and when Skoda have a solution.

In the mean time its back for yet another day at Autosales, oops!!!!!

I just got my car back from service. It was definately, without a shadow of a doubt, the tyres that had been worn uneven. They did the 4-wheel alignment thing and all corners were within skoda spec. However as they specialize in racing with VAG stuff they have better clue on things than most garages.. so they adjusted the alignment to what they felt was a more proper setup. They did this still staying within factory spec.. so it's a minor change.

As another curiosity, totally OT, I had a courtesy car from them to run my daily business while Scodillac was under service. It was a 1.9 tdi VW Caddy Life with DSG box. I was quite suprised to find that DSG is A LOT smoother under that VW than what it is in my vRS. I don't know if it's the engine character or gear ratios or what it is but it was a lot more fluent in traffic. Back to driving my Scooby, giving it loud pedal in city traffic is like getting a fist to your face when compared to smooth like a baby's butt VW DSG. Go figure...

I won't know if anything has really been improved until over time when I get my winter radials under the car as they are less worn. The summer tyres are pretty much a lost cause as they've been run to ruins because of this setup!

The garage had also made some calls to "skoda finland" to check wether they know of such issue. The answer had been that some cases have emerged before but they don't really have a clue on what's going on. They did mention that one hunch is that it maybe related to tyre brand! These cases apparently seem to fall under a couple of tyre brands only. So it may very well require brand new tyres from some other brand that's been currently used.

I do not wish to fault & shame the tyre brand as I can't say it's their fault. But as reference information I'm running on Bridgestone Potenzas.

Latest Update

Have now been contacted by the dealer and told that Skoda have looked at the engine data supplied and suggest that the vibration may have something to do with the EGR valve/system. Dealer now wants the car for 2 days to check this possibility out. Hope this is finally a solution and not another wasted trip to the dealers.

Hmm that does sound very BLT.

I wonder, is the CR170 Euro V compliant or Euro IV?

According to the brochure the CR170 is Euro V.

Well when the fabia VRS moved from Euro III to Euro IV there were issues with it stuttering as Andrew said.

It came down to EGR issues to meet the new regulations. Maybe it's something to do with that, however since the CR is a new engine one would hope it isn't that.

Update

Car went to dealers last Thursday, for 2 days, on advice of SUK for the "E.G.R. valve to be blanked off" to see if this had any bearing on the vibration. Typically despite happening constantly since August, even during dealer scrutiny, and after approx. 4000 miles the vibration seemed to have stopped a few days before this latest dealer visit. Dealer replaced the gasket on the E.G.R. for a thicker/ modified one anyway. So far so good, not sure if car has fixed itself over time or it was my imagination and the gasket has cured it. Will keep you posted on the longevity of this "fix".

I had a simamlar problem with an ibiza TDI vibrating at low revs as the turbo came onto boast. It took a tyre fitter to point out that the intercooler was lose in the wheel arch to get it fixed. The car had been to and from dealer countless times and they good not fix it. Then when took it in and pointed out it was loose was fixed same day.
