BG Fluid Services
Forgive me if this is a repeat question...but a search of the archive rejected "BG" because it doesn't meet the three letter minimum.
Anyway, I had my (new to me by one week) '06 CDI in to the local dealer today for CEL...turned out to be one bad glow plug and they replaced all of them.
Of course the service advisor was eager to sell additional work...and with 36K on the clock, I decided to go for the BG transmission flush and differential lubricant (being due at 39 or 40K anyway, depending on what you read)...also power steering flush although MB doesn't seem to require it. However, based on some excellent information from one of you, I declined the BG cooling system change...having been persuaded that it's really better not to replace the MB coolant earlier than the massive 15 years and 100+K miles recommended interval. If I continue the BG changes every 30K, they say they add some additonal indemnity against component failure, up to $4,000. I also wormed a 20% discount out of the service department.
So...what's the consensus? Did I do the car any harm? Or did I just waste my money? Or was this potentially a good move?
My only concern is whether the BG product meets MB spec...but would an MB dealer sell it if it didn't?
