Car has been owned for 5 years i bought it at 91k. All injectors were changed with new ones at 75k with receipts. Anyone who knows these engines know that this is the major surgery this n53 engine requires. Ive kept up to date on all maintenance, I've done all maintenance myself with trips to bmw specialists for any diagnostics. I have all the receipts to prove this and you are welcome to call the bmw specialists to check they will have my record there. Further to this, I will happily show you the engine and even under the car, I have a set of ramps so you know exactly what you're getting. The only slight annoyance with my car has been the Airbag light which has been there since I bought it 5 years ago and I have the receipt from the specialist to prove it. To fix it will involve swapping out the airbag module in the car. The placement of the airbag module is under the rear console, so I prefer not to repair it as once you take off all that interior parts, they will never fit as flush as before.
