LITTLE HISTORY
About 11 months ago (5 miles) I did have it at a dealership for the Renntech ECU upgrade, rentech headers installed when they saw a leaking right rear shock. they said i should fix it so I did 2068.00 dollars later.
Can anybody decode theses and give some advice.
I would check the fluid level in the ABC tank and make sure it's at the correct level.
Turn the motor off and let the car sit for a few minutes. Clean all dirt, dust and oil around the reservoir so that you do not contaminate the fluid, pull on the dipstick, clean it with a very clean lint free cloth and put it back and measure the level. It should be at the top notch in the dipstick.
