We have noticed increased amounts of blowby from the newer TSI/TSFI
engines and these vapors are contaminating the electronic boost sender and
Shown in the pictures below is the inside of the vacuum line, cut 2 inches
from the electronic boost sender inlet, from a 2012 B8A4 72 hours after
initial installation. The condensation of the vapors fouled the boost
sender and caused very erratic readings.
As of June 1, 2012, we are making it a warranty requirement that the
supplied inline air filter be installed before the electronic boost sender
as shown in the picture below. Non installation of the inline filter will
result in your warranty being void.
Customers who have purchased a Podi electronic boost gauge prior to June
1, 2012 should install the inline air filter ASAP to prevent damage to the
electronic boost sender. Your warranty is still valid in the case of a
claim within the one year warranty period.
