Drive more often, clean out garage, get a cat

Jan 07, 2020,06:06 AM

My friend Bela brought his pristine, low-mileage 2015 Audi A8 V6 over a few weeks ago - several trouble codes were indicated. 

Since I have a diagnostic tool I pulled the codes which indicated no warm-up air injection to the catalysts. On both banks of the engine. That indicated a common cause.

I found a Technical Service bulletin for those two codes indicating a warranty fix requiring 6 hours of time to pull the manifold and water blast the exhaust manifold ports and replace EGR pipes, etc. About $2000 labor.

Then I raised the hood and found nibbling on lots of rubber, and a few nests of stuff in the crevices around the engine compartment. Mice perhaps?

Yesterday, post-holiday season, he took it in - the little buggers had eaten the hoses that route air to the catalysts warm-up system, which run in the valley under the manifold. Along with a few wires, etc etc. Removing manifold, installing new hoses & wires and so forth is $1500.

I suggested he try his homeowner’s insurance and surprisingly they agreed to pay the excess over his deductible. 

Moral of the story - drive car more often, clean out garage, and/or get a cat.

Applicable to us all, I guess.

But what if it were bigger rodents? Keeping a garage clean is always a better option

Good advice!

My internal combustion engine car sometimes isn't driven for days. Hoping there are no mice, but if there were, they might start chewing on the hoses. Even more reason to drive it more often!

It could . . .
