Like the title says. What I was thinking was that the dust maybe clogged the O2 sensor but wanted the opinion of the experts. I drove on an unpaved road for about 45 mins and the light came on about half way through.


Thanks,

I would pull the codes and see what they are.

 

got it, will do

thanks,
Chet

 

sorry to hear about your T5-R by the way
and thank you for your generosity with advice


Chet

 

could be a dirty mass air flow sensor or a dirty air filter. Pull codes and check. Maybe an O2 sensor....haha it could be coincidental that it just wore out though, unless it rattled loose or something

 

I was thinking the MAF too. Air filters are not perfect and stuff gets through them.

 

I think o2 is a stretch... from dust.

maf seems obvious... but codes are absolutely required to be anywhere close...

 

i ve seen codes for system to rich on vws with extemely dirty air filters. the motor is starved of air. pull out that air filter

 

Thank You I hope she will be running again soon.

And your welcome on the advise.
