Get the code read to determine where the problem is.
Changing the oil is highly unlikely to cause an emissions problem.
Surely they did more that just change the oil for 850 pounds. Changing the
oil here in the US costs about $75 if you use the most expensive oil around.
I filled my E46 325ci engine with Castrol GTX 0w-40 and the 'Cehck
Engine' light has appeared on my dash!
Have i done something wrong!?
my hand book says
"Exhast emissions have deterioated. please arrange for a bmw service
Im surprised s i had have had a £850 oil service just 6 months ago,
and £250 later on for something else?
Is this serious, as maintence is starting to annoy me, it has only done
48000 miles and i only really drive it on weekends!
Can you help?
