Adjusting the nut behind the wheel TDI improving

Therefore I can reccomend a grille block, it does three things for diesels.. it helps improve aerodynamic drag, it helps reduce the airflow over the engine which means improved warmup time, and a curious bonus I've discovered is that if you seal it in, it helps reduce heat loss when the car is parked. Thus the engine is a couple of C warmer in the morning. I strongly suggest blocking the UPPER part of the grille, not the lower part.

Adjust the nut behind the wheel.. let's assume you've done that.

check your Mass Air Flow sensor and your Exhaust Gas Recirculation... which often get horribly coked up.

Dear Derek,

Your advise makes a lot of sense to me.

I have a Skoda Octavia 1.9 TDI, and have done:

- Upper grill cover
- Rear wheels mud flappers removal

Please, can you explain what is "adjust the nut behind the wheel"?
Maybe a picture?

I am very interested about learning how to check/clean the MAF and check the exhaust gas recirculation. I ordered a VAG cable & software to plug into my notebook.. Do you thing these systems can be checked with the software before removing them?

Tks.
