I have an '04 Jetta tdi, with 137,000 mi. I have had it since '06ish , and put almost 100,000 of those miles on it. I have been changing the oil about every 8,000, using synthetic oil. It has had a few minor repairs done on it in the last couple years. So, of course, I've just been braggin' up a storm over this car, how much I love it and so on.
THEN, Just recently the emmissions malfunction indicator lamp comes on as I'm driving over a steep mtn. pass. It's really blowin out smoke, and feeling gutless. So I take it to my mechanic and they clean the maas air flow sensor. The light stays off for about 2 days. I take it back to the mechanic, and decide to have him replace the sensor. The light comes back on about a week later. I take it back to the mechanic, he comes up with a list of things to fix on it (totaling around $500) but does not guarantee that will solve the problem.
So I take it to another mechanic to get a 2nd opinion, he says to just trade it in , that it could be a broken ring , (and something about back blow? can't remember exactly) that would cost around $4,000 to repair.
I'm wondering, now what do I do? It is currently at a 3rd mechanic getting a more thorough diagnostic. This is my first diesel , so I am clueless and want to understand what is going on with this engine.
Any thoughts, comments, suggestions, answers???
