so..all of a sudden..all lights on dash..no rev counter, no speedo, fuel gouge works. starts fine, only drives in 3rd gear, no tiptronic,, car leans to left,
pleeeease any advice?..battery charge is at high 13 volts constantly,,also the obd scan tool wont connect to car fully,only limited readings

 

13v charge is too low. Could be an iffy battery, alternator or IBS.

 

I'm with this. You first have to correct your voltage. Was something done to the car before all this happened or did it all of a sudden start acting up? Do a voltage test on the alternator itself then on the battery while the car is running. This will help isolate the issue.

 

voltage reads 14.3 at alt and battery..it was running fine ,then we stopped, turned off, then turned on and every warning light came on..ot would drive only in 3rd (auto) tiptronic wouldn't work..no speedometer or rev counter working..only the fuel guage..lights,(front and rear)wipers ,seats sunroof
.all work fine, no green light on drovers door and window switches not operational..cannot connect through the obd. The big black relay in the boot is activated even if the key is off, it has 2 live feeds constantly going to it...appreciate the answers and anymore..thanks
