2009 Cooper oil pressure indicator

[paulh2602601]

Greetings, everyone. I purchased a Cooper S with this defect. The apparent pressure sensor has been installed by a garage, suggesting it is an authentic sensor. Nevertheless, the light illuminates. No fault codes are associated with the issue; only the footwell module requires reprogramming. The battery was completely depleted.
It initiates on the first attempt and operates well at idle. The light activates once the engine has reached optimal temperature.
My inquiry is regarding the initial steps for inspection and replacement. ???


Thank you in advance.

The oil pressure light is unrelated to those codes, in my opinion. It is necessary to utilise a wet oil pressure gauge to ascertain the real-time pressure. It is common for an engine to exhibit oil pressure when cold, but as it warms up, the pressure may drop to zero, triggering the warning light. Likely causes include significant wear in the cylinder head where the camshafts are located, any grooves indicating irreparable damage, and potential crankshaft damage. To assess this, remove the sump and inspect the bottom surface; any grey colouration suggests that the crankshaft is compromised.

Thank you for your response. I anticipated that you would. I recognised that the codes were unrelated, yet I felt compelled to disclose them.
It appears that I will be undertaking one of your rebuilds, which I find rather agreeable, to be candid. Any recommendations regarding which components to get would be much valued. This mini is too valuable to damage, and my objective is to maintain these minis in operational condition. It has only completed 80,000 kilometres.

I utilise Yeo and Smith's machine shop in Plymouth, where an 81-year-old craftsman expertly grinds cranks. His ingenuity has greatly benefited me over the years. I also procure Kings bearings, which he sources in the appropriate sizes, along with rings. I utilise FAI and head bolts. FAI head gasket and FAI timing chain complete kit, including the oil pump chain kit, are excellent quality at reasonable prices. I utilise either Febi, FAI, or genuine oil pumps. Best of luck, as the initial attempt is usually challenging.

I greatly appreciate it. Your expertise is consistently valued in this forum. You ought to possess your own part.

In January, I executed a ten-year lease for my own mini specialist, to be named Mini Mike's Mini Specialist. Last week, I submitted my resignation at work, which was met with disapproval; however, I maintained a cordial demeanour and was offered incentives to remain. Nonetheless, I prefer to dedicate myself to working seventy hours a week for my own venture.

Your situation will improve—progressing positively, with additional minis to be preserved!

I believe it is time to proceed with my plan, which has been in development for several years. I aimed to minimise risks and avoid incurring debts while establishing it. I now need to purchase one or two two-post ramps; I have already acquired most of the necessary equipment, with significant expenses incurred for an Autel device and other diagnostic tools, including a scope. Additionally, I am considering constructing a DPF cat cleaner that can wash filters without necessitating their complete removal from vehicles, particularly for all Generation 3 cars, which require subframe disassembly. The remaining tasks can be accomplished with a day’s work on the floor, and cleaning the filters in situ will save vehicle owners approximately three hours. There remains the option for complete removal and remapping as well. I already work seven days a week, typically 10 to 12 hours on weekdays and 8 hours on Saturday and Sunday.
