Wow, the response to my problem is amazing. Thank you all so much but I have figured it with your suggestions and a boost-knowledgeable local legend here in Calgary.

The answer to my problem was indeed a MASSIVE BOOST LEAK because my friend found a massive hose connecting the Vacuum Canister was disconnected after inspecting every line (and finding it in great condition) except for the one inside the fender on the passenger side. I am a little angry I didn't check there sooner. He said it was hanging there so he plugged it back in, and now the primary turbo is boosting again 11+ psi on 3500rpm (I got to get a better non-ebay boost gauge to accurately measure!)

@ukscoobyguy;

You are right on the money. The flashing CEL gave me a 173 code, however when my friend hooked his expensive OBD2 code scanner into it, it gave a P1241 which was something going on with the primary turbo. I don't know if the flashing CEL code pattern was in THAT way because the REV D model I have was OBD2 compliant and others who gave a more "traditional" code weren't? I am not sure. However if someone else has a flashing 173 code and haven't hooked in a OBD2 scanner, it may correlate to a P1241 code?

@Kong

There was no hissing in Line 1 but after he reconnected the big hose to the vacuum canister, there was hissing. You were right that there is something going on with the vacuum. I should have checked more closer to the vacuum canister like you suggested much earlier.

To everyone, thank you for taking the time for helping me and making me learn more about the car! I hope this can help others and I'll post my car once I fix the little things up and make her more 'presentable'.

I am still mystified by the CEL flashing sequence. Is it possible my vehicle is OBDII complaint? I hooked a cheap Ebay bluetooth OBDII scanner and used the Torque app but the Torque app said it cannot connect to the ECU. I am going to see if any of my friends have a more legitimate OBDII scanner I can use and see.

If anyone has any insight to the CEL sequence as well, don't be afraid to chime in

Thanks for all the help so far

Zanzarah,

it seems I have the line 10 and 12 hooked onto the right places. I will check the operation of the solenoids tonight then. Thank you!

I will unbolt the BBOD and do the diagnostic mode check and see if all the solenoids are all clicking.

To add to this, I have a question about the BBOD external lines for 10 and 12 for the REV D. I am unsure if this was the correct set up, and i will try to get a photo when I get home. In text though,

1. I got line 10 terminating into a connector that connects it to a slightly larger diameter rubber tubing and goes directly down somwhere. (it was midnight. I was tired and didn't check what it was. My apologies)

2. I got line 12  going into a SOLID pipe that spans the manifold and disappears across the engine...(Again, it was midnight when I was working and didn't trace it all the way to the end)

I am unsure if this is correct. I hope it is not and this is my problem. Can anyone confirm and maybe upload a picture? I have seen some drawing diagrams but it has Line 11 (from rev a/b/c I believe) and it is a little confusing for me.

Thanks heaps!!!

Thanks for all the replies KONG and duncanm!

duncanm,

My boost gauge is attached to a previous "T" line ( see attached picture) that was blocked off. I'm assuming there was a boost gauge or something here from the previous owner so I unblocked it and put my own line into it.  Is this a suitable area to sample boost on a 2002 BE5 Rev D? I believe it was working because my boost gauge was showing boost (like 5-6 psi) past 4500rpms.

The P1703 code seems like it would show up on OBDII scanner screen, not as a code via flashing CEL because of the "P" but that's all I could come up with from the flashing CEL lights. My BE5 has a manual transmission so I don't understand what you mean by auto box. Does that refer to something other than the transmission?

The small thin vac line runs from the BBOD and attaches a hose that leads into the fender, I double checked that however I don't know if the line is okay once it's in the fender. I can see it turning into the hard line behind the bumper and it looks good. It disappears again into the passenger fender and to the Vac Tank and I haven't peeked inside yet. That will be the next task tomorrow I guess!

I will make sure the check-valve is okay however I don't know where they are. There are two one-way valve/cylinders on the passenger side on the firewall. Is that what you are talking about?

Kong,

I did unplug the BBOD harness, and another harness in front of it to take it out of the car. I will double check for wiring and pins that are faulty on the line I unplugged tomorrow I suppose. 

Thanks everyone.
