Passat 2008 turbo actuator fault

[jasonmking]

I Have read that if you have a turbo actuator problem that you can free it up by pumping it manually, just wondered if this was the case and if so the locattion of it in the engine bay

Thanks

You'd need to lubricate it as well

Turbo ACTUATOR is a vacuum unit. If it don't work you need a new 'un.

TURBO ACTUATION can't be freed by pumping it manually, at least not for long. Maybe long enough to sell it to some mug, if you are lucky. That would be very ungentlemanly conduct that shouldn't be encouraged.

All that pumping it does it to help you diagnose a problem inside. It then needs removal and either replace/refurb/clean out.

It has never been possible to free an actuator by pumping or lubricating it. On a pd you can vacuum test to see if it works. Common rail actuator are electric so nothing to pump..

ive had the same problem! If it is comeing up with a fault code its more than likely that the diaphragm inside actuator is goosed!! if this is the case then you will need a wastegate repair kit from vw witch costs £98 but you will also need a vw specialist to fit it as the adjustment needs to be bang on otherwise it wont put the light out and you will run the risk of further damage! at a main dealer you will be looking at 1.5 hours labour!

Actually, it seems to be the lower seal rather than the diaphragm that fails. When they install it, the actuator rod is not held and the seal gets twisted. Over time it develops a split. I have heard of people squirting some silicone sealant at the split to get it going again. How long it works for - I cannot say. You may benefit from heating up the shank of a 10mm ring spanner and bending it to about 100 degrees. It really helps when you are trying to get the bottom nut off the actuator rod.
