I have a 10-year-old VW Polo that I bought new from an unnamed VW outlet in January 2014 (it had 300k on the clock).
Being a complete eejit, I have used the car dealership to service the car since.
Since February 2012, it has had an ongoing problem with voltage to the throttle. This problem causes the engine to “knock” and the car runs so roughly that it is undriveable.
I’ll spare you the details but after paying *insert car dealer name here* more than $4000 over several visits to fix the problem, on 24 October I was gouged by them for $1400 for a “routine” service, which included cleansing the throttle body and replacing the windscreen wipers.
First time I shut the boot afterwards, the rear wiper casing fell off.
And last Friday, eight days after the throttle body was cleansed, the engine light came on and the same fault from Feb 2012 came back.
My advice? If you buy a VW, don’t take it back to the dealer for servicing.
