I have a Hyundai Tucson from 2006 with automatic transmission. I bought it second hand for a few months. For 2 months the check engine light is on. I have made a test and dicovered an error code p1529 - which seems to be a multfunction in the automatic transmission box. - no communcation. i have tried everything possible: I have changed the oil of the automatic transmission box, I have changed the valve which commands the covertor, but after a day, the check engine light is on again.
The cars works just fine, the only problem I have noticed is that, at higher speeds ( 100miles/hour) the turation is higher than normal (3500-4000rpm). But the cars works ok, no noise, no nothing.
Once the airbag light was on for a few days. But I erased the error code and it didn-t light since then. Maybe a conicidence, who knows.
I am just out of options. I am so upsat and I do not know what to do. There are thounsands of opinions but no one knows exaclty how to help me. In Romania there are a few Hyunday services and no one knows what to do.
If any of you had this problem,please help me.
I have run out of options.
