Started throwing these codes recently. Goes into limp mode with Commanded boost and Boost actuator showing 10% on both banks (on IID) until ignition off/on.

Had it on a ramp yesterday. Seems to be the B side (UK passenger side). Driver side can be seen and appears to be working fine.

B side actualor rod is completely concealed behind driveshaft/engine mount and other paraphernalia.

Can hear a distinct sqeak when turning ignition on/off as actuators do their start up cycle.

Sprayed copious quantities of WD40 & spray grease up into the area with extended tube but couldn't get rid of squeak.

Still throwing codes. Oddly, open road driving seems ok (at the mo.) throws codes when you get into a 30 limit.

Going on hols tomorrow - 200+ miles each way.

So, two questions:

1 - It's still quite driveable in this limp state. Any issues with taking it on hols like this?

2 - Anyone managed to sort this issue on a L322 short of replacement?

3 - If it needs to be replaced. What's the best approach? 2008 TDV8 Vogue
