Hey, thanks for making this! I have a question. Have you ever removed the
combi valve from the 1.8T engine that was also found in the Golf and Jetta
from this generation? My 2002 GTI is throwing the same P0411 code, and I’m
thinking the combi valve is the culprit as the SAI pump and other
components seem to work fine. I don’t have the same bracket going from the
head to the combi valve, and there are two hex bolts that look like they
might be a similar bracket but they are obstructed by a coolant hose. Is it
better to just try and wriggle the combi valve out by itself, or to take
the bracket? Like on the VR6, the 1.8T combi valve has its attachment bolts
coming up from the bottom.
Thank you very much bendpak7000 for watching the videos and I’m glad that
you liked them. Where and how did I gain my knowledge which is a big
question? On the Suzuki video of installing the intake manifold that I did,
I mentioned my background there. In summary, my Dad was an auto mechanic
for over 40 years, so I grew up with him working on cars. However, I went
into electronics working at Sylvania as a color TV troubleshooter. Later,
went into industrial maintenance as an electrician. cont…)
and spending lots of money to where they should know how to diagnose. So,
got back into repairing my own cars again, taking an interest in the
electronic systems of how they work and how to troubleshoot them. Although,
my background is mainly in industrial maintenance, cars are really no
different in diagnosing them. It’s just a matter of understanding the
systems and from there you can devise your own methods to diagnose as you
heard me mention several times. Thanks for the comment!
After working at several companies as a maintenance guy, went back to
school for the second time and earned an ASEE. Got into control wiring of
automated equipment. Later, went back to school again for refrigeration and
did that for about four years. Went back to school again and got a BSEE and
today I’m an electronics/electrical engineer. In the past, I worked on my
own cars, but after a few years, decided to let others work on them. Got
tired of them screwing things up, misdiagnosing, cont…)
Nothing too intimidating after it’s covered by you. Quick request: can you
show us your shop and tools?
Thanks Manny, I appreciate it!
Thank you Joe for the comment! Wow, to show the shop which is a mess right
now and the tools and test equipment would be a chore in itself. Once I get
this car back together and do a little cleaning up, I’ll try to put a video
together on that. Thanks again for watching!
Ran out of run on my last post to you Dave and forgot to thank you for
watching and for your comments.
It has always seemed counterintuitive, that drawing in room temp air will
raise exhaust temperatures, but I guess I understand the accelerated
combustion idea. It’s too bad that it doesn’t improve fuel efficiency or
engine performance. That also is counterintuitive.
The fresh air drawn in when mixed with the exhaust gases will raise its
temperature. This is because the mixture is richer when the engine is cold,
and with more oxygen added it raises the temp which then helps to heat the
cat faster. Just amazing to me to go to all this trouble with vacuum,
valves, pump, etc. just to heat the cat faster. And still more amazing is
how American cars dropped the air pump 40 years ago, yet German engineering
still needs to use a smog pump. Yes, counterintuitive.
I enjoy all of your videos you have made from start to date. You are very
knowledgeable in diagnostics. Where and how did you obtain this knowledge?
