    If its glowing under normal driving, the cat is probably blocked. Either rip it out and chuck in a test pie, or replace,depending what you smog laws are there

    vag com and check your timing and A/F ratios.
    if you cat was blocked it would effect others things as well.

    does it drive OK?

    Is your fuel pump up to the job? If not, you might be running higher than normal EGT's.

    did some looking else where and it prob is the CAT blocked and you may need a new DV why your at it, take the O2 sensor out and see if the boost goes up.
