Sometime last year, I had the first incident of the check engine light come on. The mileage on my car at that point was in the neighborhood of 80.000 (between 79.000 – 81.500). Unfortunately, I cannot prove that, since I didn’t visit a dealership. The reading on the scanner was “ P2404 EVAP emission system leak detector pump sense circuit ange/performance”. The mechanic at the independent shop proposed to change the gas leak detector pump and se we did.
Unfortunately, after about a couple of thousand miles or so the problem reappeared. My mechanic -a very reliable and honest gentleman, I would like to add –not feeling so good that the problem hadn’t been resolved, spent several hours, performing a thorough inspection, hoses, possible loose wires, etc. Nothing.
As a consequence, I turned to the dealer, seeking the opinion of the experts. AUDI DEALER
They kept my car for two days. They ran all available tests according to their assertions. After so many hours, they came up with a quite painful and extremely costly conclusion: the ECM of the car had to be replaced. The cost was in the neighborhood of $1700 plus tax. In other words the total cost, including the initial cost to detect the problem would be more than $2200.
What do you think
Thank you
