Follow up of A8 with DTC post

jwass · 03-10-2004, 12:06 PM

I wanted to report back on my A8 with DTC post of 2/4/04. The car started to show trany shifting probs along with misfire,lean & rich trim DTC's. It whould down & upshift on acceleration causing car to lurch. The tranny went into limp mode & showed DTC 17114 incorrect gear ratio. I told my mechanic to chage the MAF. He did said it didn't solve the problem & put the original back in. I took the car to the dealer. They chaged the MAF and the car is cured. They think the MAF my mechanic had was a defective part. I haven't used VAG on a WOT run to see max airflow yet. I'll check that out over the weekend. The reading was 122 g/s at 6000 RPM with the bad MAF.

Glad your car works...but normally when you get the incorrect gear ratio it's a sign of dirty ATF. Have you ever had the ATF changed? How many miles on your car, what year?

I don't understand how a problem with a MAF could cause a limp home mode on the tranny.

My car has 75,000 mi. I purchased it used 4 months ago. As far as I know the tranny has not been serviced. The Audi dealer said the MAF issue affected the shifting. Since the MAF has been replaced the tranny shifts flawlessly.
