Getting this collection of fault codes on my 330d:
49A5
4DFB
4E0F
4A6F
4A1F

Car has no lights on the dash, runs and drives fine, 50mpg on the motorway etc
My research says its something to do with the glow plug control module and one of those might be a code for the swirl flaps which worrys me as I dont want the engine/turbo to go bang.
I purchased the car from a dealership that gave me a 3 month engine/gearbox warranty so do you think it's worth contacting them to see what they can do? Thanks.

*Forgot to mention, on the first start of the day the car seems a tiny bit lumpy at idle, but im used to a Ford 4cyl diesel so its hard for me to tell as that ran like it had nails in the cylinders*
