2004 1.8T Airbox Disassembly/MAF removal pics

[Rabbit]

Does anyone have pictures or a step-by-step for disassembling the airbox in a 2004 1.8T and removing the MAF? I want to take mine out tonight and try cleaning it. I searched, but was only able to find pics for a V6 in the info base. Thanks!

no, but it is easy.

pop the grommet on top unplug the maf
unclip the hose on top connected to the purge valve. unclip and unplug the valve too
remove the snorkel in the front.
remove the SAIP hose and the turbo inlet hose on the front also.
pop the clips

flip over the lid and remove the MAF assembly with a philips #2 screwdriver.

You are the MAN!

[VAGguy]

Not a problem. You WILL get scratched up. The clip back by the firewall can be tricky.

[Rabbit]

Do you unscrew the heat shield?

[VAGguy]

first time yes, but it should pull right out with the airbox lid. IIRC the bottom of the heat shield is not connected to anything. Just tucks behind another heat shield.

I got almost everything disassembled last night - but couldn't detach the SAIP damn hose from the airbox lid. How the Eff do you get the goofy looking hose clamps off? That thing is a bugger. I'm afraid I'm going to have to cut it and then get a conventional hose clamp to replace it. Any idears?

if the hose is like the V6, you turn it and it slides out, reverse for install

This is exactly what I did. Anything that i've worked on that uses those 'one-time clamps', I just take them off and replace with a standard hose clamp when i reassemble. much easier.

[VAGguy]

yes. get a small flat blade screwdriver in the loop and pry it apart. Then use a regular hose clamp later.

WTF was I reading, I was talking about the fat hard plastic hose.
I do them like VagGuy said.

Yep, after spending 10 minutes each time to get these off (trying different methods), i finally learned this is the best way to get em off. Even this though, isn't the easiest on some of the small ones.

Got the Battlewagen back in bidness! Got the airbox apart, new MAFS in, everything buttoned back up, and voila! Purrs like a kitten. Still has the MIL illuminated, but it runs smoothly and is no longer slamming into gear. Very pleased. I'm banking on the MIL going out after a few drives. As a bonus, the ABS malfunction light went out.

Thanks for the advice and encouragement Dan. I am so pleased to have der Schlachtwagen back. I have been driving a 2009 M-B C300 Sport with 4matic all week, and I actually prefer my B5.5. Although the sport package on the Benz has gotten me thinking some sporty coilovers and a mild drop might be in order.

I'd be more than happy to help install them for you. I can do it in my sleep now.
