Wordcar Posted January 26 Share Posted January 26 I own an F15 X5 40d with a mileage of 120,000 kilometres. The car had maintenance at a BMW store in late October. Since then, I have driven a short distance before noticing a banging sound coming from the engine. Finally, the BMW dealer diagnosed the issue this week and determined that the oil level was very low, with metal filings discovered in the engine. The recommended course of action is to replace the engine, which comes with a significantly high price tag. The problem I encountered is that I checked the oil level two weeks ago and it was OK, and there were no warning indicators. It seems that BMW may have neglected to replenish the oil during the previous two maintenance in October 2022 and October 2023. Do I possess a justifiable foundation to contest BMW?

SlayNeo Posted January 26 Share Posted January 26 Challenging BMW on a car with such mileage is unlikely to yield favourable results, since they are famously uncooperative when it comes to low mileage vehicles. Establishing their negligence in oil changes would be a challenging task; what evidence leads you to believe they have neglected this maintenance? Seek the expertise of a specialist to obtain their professional opinion on available choices and associated expenses. Link to comment Share on other sites More sharing options...
Wordcar Posted January 26 Author Share Posted January 26 Hello, I appreciate your response. The concern that troubles me is the reason why I am anticipating that a replacement oil filter and oil change will enable me to, at the very least, operate my vehicle to reach the nearby automotive repair shop and inspect it. Regarding their omissions, they simply failed to do it, despite covering a distance of 40,000 miles between maintenance intervals. Link to comment Share on other sites More sharing options...
Patagil Posted January 26 Share Posted January 26 Your vehicle is equipped with the N57 engine, which is well known for its susceptibility to crankshaft main bearing failure. This issue is also seen in the 740d and 640d models, as well as in the 330d vehicles used by the police. In 97% of cases, the engine is considered unusable. Rebuilding them is seldom feasible due to the deformation of the alloy cylinder block. You have two viable alternatives: acquiring a high-quality pre-owned engine from a reliable dismantler, or selling the vehicle in its current condition. Avoid pursuing the option of acquiring a refurbished engine. Link to comment Share on other sites More sharing options...
Wordcar Posted January 26 Author Share Posted January 26 Thank you for the message. I am still somewhat astonished that such an event can occur to a vehicle of this calibre. As you said, I will make arrangements to transport the vehicle back to the UK and locate a dismantler to get a replacement engine. Link to comment Share on other sites More sharing options...
JamesStv Posted January 26 Share Posted January 26 How can you ascertain that the oil was not altered? Furthermore, what were you billed for? Link to comment Share on other sites More sharing options...
Wordcar Posted January 26 Author Share Posted January 26 The oil was last changed 20,000 miles ago, and it was determined that it would not need to be replaced for another 4,000 miles. Link to comment Share on other sites More sharing options...
SlayNeo Posted January 26 Share Posted January 26 That is an exceptional BMW. I would never let the oil in my vehicle to exceed 10,000 miles under any circumstances. Link to comment Share on other sites More sharing options...
