Ongoing problems with an 2008 BMW 320i
I just want to share the technical problems I had with my 2008 BMW 320i, n43 engine with 100 000 km on the clock. The reason for this is that I did not expect a premium car such as BMW would have this many problems, less than a year after the extend warranty expired.
I wrote about the hole thing to BMW, so I think that the best way to tell my story is by ataching the complaint letter:
I am writing to you regarding an ongoing problem with one of your cars (VIN: VG35101). Normally I wouldn’t have raised this issue with you, but I feel that your cars suffer from a low level of reliability, far lower that what I would expect from a premium brand like BMW. This is the reason why I want to bring to your attention the problems I had with my 2008 BMW 320i. A car bought in 19th of December 2007 with BMW Service Inclusive Ultimate for a period of 4 years. Because of this extended warranty, the car received regular oil changes, only in the BMW dealer network.
The problems started in late November 2012. I was driving to Craiova, Romania when suddenly the check engine light came on yellow and the car stopped. Fortunately, I was close to one of your dealers, in Craiova, namely MHS Motors. I left the car there and returned the following morning to take it in for testing. They told me they had found a strong smell of gasoline in the oil and a low oil pressure fault. They then checked the injectors and found that they were injecting too much gasoline at idle. They said all of then needed replacing. I was shocked. I wasn’t expecting a car like this to have such a major problem at less than 100 000 km. They also said that the car loses oil near the gearbox.
Having no other choice, I paid for the replacement of the injectors, engine oil and an O-ring from the gearbox (bill1.pdf attached). They also said that I should change the oil 1000km later, in order to clear all the gasoline from the oil, which I did in 21.12.2012. This is the only time oil has been changed outside of the BMW network. Because of the holidays I couldn’t find any dealer who could replace the oil. Nevertheless I put BMW LongLife-04 in an authorized BMW service. Attached is the bill from them (bill2.pdf).
During the 1000km (between changing the injectors and the recommended oil change), the low oil pressure indicator came up once at idle. I was told I should expect this to happen, and haven’t given it too much thought.
On 27th of December 2012, the low oil pressure light came up again, also at idle (note: the car had new oil, just 500km from the last oil change). The following day I went to Automobile Bavaria in Bucharest, Romania and explained to them the whole situation. They took the car in and after a day of diagnostics they came to the conclusion that they had no idea what was the problem with the car. They manually checked oil pressure and it was ok. The error code that shown up was 30C1 DME: Engine-oil pressure control, static. They instead decided to raise the idle speed, and said that it should solve the problem. I am attaching the operations report from them and their bill (bill3.pdf).
On the 21st of January 2013, I went again to the dealer because of a burning oil smell inside the cabin. They came to the conclusion that there were multiple gaskets leaking oil, and I should change them, and so I did. Again wasn’t expecting this problem from a 100 000 km “premium” car... Attached is the bill I received from Automobile Bavaria Bucharest, Romania, where I changed all the affected gaskets (bill4.pdf).
Today, 12th of February 2013, the low oil pressure light came on again. Also only at idle, also not reappearing after the engine was shut off and restarted.
Now, given the fact that no one knows what is wrong with the car, I have no idea what to do next with the low oil pressure problem, and so I am expecting a response from you on how I should proceed.
I can’t stress enough how disappointed I am in the reliability of an otherwise great car...
