Re: Block heater BTDT and 3" cat source?

    IMHO, the block heater is the only way to go. They are effective, safe,
and reliable. I use mine routinely in the dead of winter (-20 to -40 C). The
car starts easier and warms up quicker. The dipstick oil heaters may work in
SoCal, but aren't very effective at -40; they don't have enough surface
area. The only other type which works mounts in the heater line. They heat
and circulate the coolant through the heater system and the block. Not as
good as a block heater because the heater valve must be left open for them
to work, plus they have the same power output as a block heater but more
surface area to radiate the heat (block plus heater core).
    Sorry, but I don't know which frost plug my heater is installed in. I'll
see if I can find it the next time I'm crawling around under the engine. The
only caveat is that there has to be enough space behind the frost plug to
accept the heater. On some engines ( I don't know about Audi's), some frost
plugs have very little space behind them and only certain plugs can be used
for heaters.
