where are the most common vacuum leak places that cause the evap code on the R53/52S? I found signs of mice under my hood and would appreciate some pointers on where to start looking?



Thanks!

 

Change the gas cap to start

 

Gas cap is first.

I had a large leak that was fixed by replacing the purge valve by the intercooler.
I had a small leak that was caused by a leak at the DMTL pump connector.
The charcoal cannister can leak due to age also.

Good luck!

 

Try a smear of Vaseline on the gas cap seal first!
