Wondering what others have seen at this mileage I’m at 61k 209 535xi on the OD I don’t drive hard just short trips mostly I got a sweet deal on this service for $300 but wondering if I should wait longer ? anyone else had this done around this mileage ? or any other recommendations to keep her tip top I did the plugs last week and new coils , any other ideas are welcome

 

I did mine around 58K.

 

I'd do it. The price is right and your up there in miles.

 

Damn!!! I want that front bumper!!!!!!!

 

I think it has a lot to do with how the car was driven prior. My car has 162K miles (08 535xi) and I've never walnut blasted. That being said, I drive mostly long highway miles, I use SeaFoam somewhat reguarly, and have never had a problem. If the car was used by a commuter, similar to what you describe, then I'd have it done...assuming you are experiencing problems with it. If you are not then I'd save the $300 for a future service, as your driving will likely result in needing it eventually.

 

My 08 535i had just over 100K when I had walnut blasting done. It was a commuter car, incredible gunk in there that had to be scraped out before walnut blasting would have any effect. I thought the car would be transformed and a slight stumble on heavy acceleration would be remedied, but in fact the car went on half power the first time I tried to really boot it. Took it back to BMW, problem was diagnosed as glaze deposits on 2 sensors in the head that monitor oil quality, which limit the engine to half-power if the oil appears too thick. That fix restored the power and the car feels stronger than it ever has before.
I anticipated that walnut shell blasting would also improve fuel economy, but in fact its been going the other way. I guess I booting it all the time now!
The bill with new gaskets for the transmission and differential and a few other things (like $104 wiper blades - WTF???) was $4500.
