My check engine light came on Monday night. Car was fine sunday, then Monday evening I went to turn it on and light came on. No issues as I had to make an apt to get my oil changed anyways. Had that done and a diagnostics done today and they said my secondary air pump (or pipe I really need to call back tomorrow as I was working while talking and my work requires all my focus) was cracked which set off the light. But that I also have a leak in my Transmission Harness (I was at the dealership so they quoted crazy numbers!). But I called my dad who is a mechanic (6 hours from me) and asked him to call Lordco (auto parts place in Canada) and get a quote as my cousin owns it and I get a large discount from them. He instead called my brother who fixes VWs to ask if this is typical as he had never heard of the harness itself leaking. the Advisor I talked to said the mechanic said “The transmission harness is leaking itself”. But my brother says it is very rare. I was told still drivable for now but get it done asap. But is this typical of a 2008 VW Rabbit? Anyone else had this issue? Costs of repairs? I know air pump/pipe is easy fix but still issue.
Thank you in advance!
