V70 D2 2014 Poor Running When Cold

[jmayna]

Hi All,

Got an issue with my V70 D2 (1.6 Auto) when starting from cold the engine runs poorly and can even stall when trying to pull away first time. As soon as it's running for 100m and changed a few gears, it's absolutely fine.

I'm suspecting a faulty lambda sensor, and originally I had no codes come up at all - but recently I've started getting P0069 indicating a faulty boost sensor.

I've read that there could be multiple boost sensors, there is one that is on top of the engine pre-intake manifold that is easy to get at, but not sure if there's one on the intercooler or not and it looks like a pig to get at. I'd arther not remove the bumper to just check if there is one hidden there or not - does anyone know if there is indeed a second sensor, and if so, is it on inlet or outlet side of the intercooler? Thanks!

when was the fuel filter last changed? AND is it a genuine volvo spec one with the blue dot on top? Others ARE inferior.

Don't think it has been changed in a while - how easy are they to get to/find - are they in the engine bay or back at the tank? I'll have a look later on...
