Lazy/slow actuator or wastegate?

[Poodle]

Ruan's got a good point there, didn't think of that. As Jonny says, may as well try unplugging the maf first since it's free to do.

I've not heard of a wg coming loose before, could be i guess, don't see how lifting off and reapplying throttle would change anything though...

Direct fit for the hdi, you've got either the k03 or the gt15, that's it i'm afraid. Or Jonny's gt20 set up.
