Multiple DTC codes over the years, multiple causes and fixes, some under warranty, some not.It's just simply too frequent, but has not left me stranded.
The check engine light (CEL) came on and the code called for a faulty MAF (mass air flow sensor). Replaced it with a new Bosch MAF and 20 kilometres later the CEL came on again. Took it back to the shop and once again the CEL called for a faulty MAF. Replaced it a second time and 20 kilometres later the light came on again. The mechanic was stumped and since the car works fine, I got my money back and now drive with the CEL on all the time. The mechanic owns a VW only repair shop and has done all the work on the car to date.
Update from Sep 5, 2014: So it turns out the MAF was not the culprit. The problem was a hose that goes into the EGR. It's a larger radiator style hose that retails for about $150.00 at VW. The hose works it's way loose and creates a leak that 'fools' the car's computer into thinking the problem is MAF sensor. It's a fairly common problem.
I just bought the car new, then the engine light comes on indicating an emissions problem. I love the car and the mileage the diesel engine gets. What frustrates me is the fact that the dealer replaced the o2 sensor and that did not fix it. So now they want to replace the engine wiring harness!! It has been 3 weeks so far and I still have to wait because the dealer is waiting for the right harness to show up. I`ve driven the car a total of 2 weeks before all this started. Buyer beware!!!!!!
