Hi All

Bit of a late one on this subject, wish I hadn't had it done but I think toooo late now.

However, I seem to remember for Audi A1 tdi, there was a letter that said, apart from other related things, there was an addition to the air inlet somewhere of a "wire mesh" to "improve" the air flow.

Can anyone confirm that and/or other, and where this "mesh" would have been fitted?

Also, has anyone looked into "reversing" the process to get back to the performance/economy that we had before the event?

Maybe, someone tried some of the "black box" tuneup devices to improve performance?

I would be interested to hear any of these.

My car has just past 105,000

Many thanks

The mesh restricts airflow I believe to help lower the emissions. I'd recommend you speak to darkside developments, Celtic tuning etc to see if they can map it out. 

Thanks Steve

No probs
