Scary drive

This was scary a F30 ,,,,,customer said the car got into a slight accident hit the curb and the insurance company fixed it,,,,they replaced the left front tire and wheel and had the car aligned and told the customer the car was fixed,,,customer took the vehicle and said it drives funny and making turns do not feel right,,,,I get the car and removed the lower engine panel and this is staring at me the EPS steering rack cracked in two,,,,lol,,,the insurance company had to buy a complete steering rack and eat the core charge because the old steering rack was not reuse able,,,,I can’t believe the guy the aligned the car didn’t see this or feel it when he drove it,,,,maybe he didn’t drive it after he aligned it.

Bonehead mechanic

Got this the other day,,,,E90 came in with check engine light on,,,,I could tell some kind of backyard mechanic has been working on this car and trying to fix the problem,,,,but they made the problem worse. The faults were lean mixture and airmass meter faults,,,,so I decided to smoke test the engine and found major leaks around the valve tropic motor and oil everywhere,,,,I removed the valvetronic motor and found it silconed in place with the whole gasket in 2 pieces and siliconed trying to seal it up with silicone,,,,,all they had to do is buy a new gasket and no more air leaks.
