See this entry for the backstory:
When I got to the VW dealership with the Jetta, I told the service manager that our trusted mechanic told us that we needed the ECU flashed. He I told him the which lights were on and that the diagnostics showed the engine was misfiring on all cylinders. I also told him that was not the case. The engine was running smoothly.
He said, “It’ll be $160 to do diagnostics.”
I replied, the diagnostics were already done, could you please just flash the ECU?
I was informed that they couldn’t do anything unless they performed the diagnostics themselves.
I said, Fine.
Ninety minutes later, the service guy comes out and tells me the right rear ABS sensor needed to be replaced. OBTW, that’ll be another $300. Apparently they can’t complete the diagnostic until they replace they sensor.
I bought all four ABS speed sensors for the Jetta for $25.00 the original Volkswagen part just cost me $206.99. Nearly 4000% more than the after market part.
I spent over an hour trying to remove the driver side rear ABS sensor and just couldn’t get the thing out. I have successfully changed out both of the front ABS sensors, I had to drill them both out. It was a serious pain. I cannot get in to the rear ones to drill them out.
The car should be labeled “NO USER SERVICEABLE PARTS”
