New XC70 owner random judder

[tommyweaves]

Change the boost sensor anyway. I had mine at a main dealer, and it didn't log a code of any sort. But they looked at the live data and the boost sensor was giving a reading 10x out of normal range.

It's down by the passenger side of the intercooler on the pipe at the bottom. At least it is on my 2011 D3 manual. I think it's harder to see if you have an auto. I expect it's a reasonable DIY job.

I think I may put it into the main dealer to see if they can find the issue, the indy checked all the sensor and apparently they were all fine

Well was in the local indy volvo garage on Thursday good news they felt the intermittant vibration on a test drive on the motorway, bad new they've never felt an issue like this before, gave the car a thorough check over found nothing that could be causing the issue, and no fault codes logged, and his 20 years experience never felt an issue like this, as normally a vibration is constant but this comes and goes at a set speed and does not stay constant.

So book in to volvo on Thursday to see what they can find, fingers crossed, as a last resort if they cant fons anything ill order a boost sensor to see if that sorts it

Hang on, you didn't mention a "vibration" before! I thought it was hesitation/judder?

Sorry meant judder, it's like the engine judders forma second, then runs normally, no rev drops etc

Ok, just thought I'd check! Otherwise I'd be suggesting completely different solutions!


Pretty sure it's an electronics issue.

The only thing they thought was it may be a gearbox issue or the start of one, but it shifts gears fine, theres no jerky ness, I drove the car all week to work and back no motorway driving and it was spot on, even at 60 no issues, but as soon as you go 70 or above you just randomly get the judder intermittently

Have you done what was suggested at post #2 ?

If not I strongly recommend you do. Probably a good idea anyways as they often get neglected until there is a problem.

I have done parts bingo on a number of diesel cars I have owned and found this out the hard(expensive) way.

Good luck Thursday.

Cheers for the reply the indy garage checked the fuel filter and it was fine I'm going to mention this and the boost sensor to volvo tomorrow hopefully it will be somehting simple and cheap! Lols

Well just heard back from volvo and cant say I'm convinced lols, on dropping it off I was told they were really busy, so they would call but they didnt know when, not an ideal start as I thought they wont want to spend much time on it. Explained to the receptionist that the problem only happen at motorway speeds and was fine driving around town etc.

So as I hadn't heard by 3.30 and the garage is an hour away I traffic I gave then a call, service girl says we read the codes no codes ( em I told you that it had been to a local garage and no codes were found) so it went on a short test drive ( great garage is not close to anywhere you could get up to 70mph) and the fault didnt appear, so erm we did a software update that fixed similar issues reported on other cars, ok what software update, er dont know. If the problem is still there call us back and we'll book it in for a couple of days to fault find.

So I'm pretty sure it wont be fixed as they've j ust done the routine software update that they do on any service, and as they were busy went on a short test drive so didnt get up to 70mph sondidnt feel the issue and are happy to just charge me for the update grrrrrr #nofurtherforward
