Erratic belt warning

[Bel Masetto]

Hi all,

Five months ago, I've noticed a permanent belt warning faillure on my MY03 996TT, and Porsche Service replaced the belt base connection; this replacemend was made at no cost, because the previous owner has replaced too the belt base due to a similar issue.

Coming home today, driver seat belt properly attached, I have noticed that the belt warning alert is erratically on and off. When on, moving softly the belt connection base restores the normal condition, but belt warning apperars just awhile. One more touch, and warning is gone, it appears again...and so on.

This issue seems to be related to the belt's base electrical connection, but considering the previous replacements, it sounds that this repeating problem may have other causes.

What should I check ? Any ideas ?

TIA

If you want to know what the fault code (and cause) is -- then you will need the Durametic Software or a shop with a Porsche PST2 or PIWIS tester.

The most common problem is bad electrical connections on the buckles (either side). The fault code will tell you which one it causing the light.

Thanks, Loren.

My car is ROW (spanish) version, so only the driver's belt is controlled by the system. Sure, the problem is on this buckle, but the question is what about this repeating faillure: three times in the past 12 months is so much...

Thanks again.

Have them check the ground (connector) wires under the seat also.
