Symptoms
Red dust on the clean side of the filter, MAF sensor faults, limp mode in the middle of a dusty trip, or a noisy turbo.
The fix, step by step
- Unclip the airbox lid and inspect the downstream side of the filter.
- Some mechanics grease the factory seal and some owners make their own seals from silicone and D-rubber, but Unsealed's preferred fix is an aftermarket airbox that seals the intake properly.
- If you find dust, clean the MAF sensor and check the turbo for shaft play.
