Cravenspeed products are extremely reliable with issues only on extremely rare occasions. When an issue arises, Cravenspeed has always been very quick to resolve the problem to everyone's satisfaction.
I contacted Cravenspeed and they will contact you directly to see if they can work with you to restore your faith in their products.
In the rare case that the manufacturer does not correct an issue, we would step in and work with our customers to 'make it right'.

So I wanted to give an update to my oil pressure issue:
I had checked the grounding on the sending unit, double checked the wiring. No open grounds, solid grounding on the ground connection. No shorts. I took the plunge and bought a new oil pump and installed it, $500 later + another pan gasket. Still had the same oil pressure problem. I just couldn’t fathom this issue since the factory oil pressure sender was not sending a warning light and the car runs great and does not exhibit the normal symptoms of an engine with low or no oil pressure. Especially with the int & exh Vanos sprockets that are dependent on oil pressure.
Solution, I picked up an Auto Meter oil pressure gauge set. Swapped the sender and installed it in the engine compartment just to verify the Marshall gauge that came with the Craven Speed Gauge Pod set. Whoa... fully warmed up after driving about 12 miles up the highway and back and then let it sit and idle for almost 10 minutes, my oil pressure on the Auto Meter gauge never fell below 25PSI. OK, problem solved. Since I was already at this spot, I changed both the Marshall Gauges out with Auto Meter Pro-Comp gauges (oil pres and Temp) I realized something else. This car does not run as cool as I saw on the Marshall gauges. The Marshall Gauges showed this car running around 180-190. When in actuality, it runs around 210-220, which is spec. I contacted Craven Speed and Marshall Instruments, since this set is not even a year old and informed them. After numerous email exchanges, the conversations stopped and no one offered to replace or refund me for their CRAPPY parts. The gauge pod hardware is great and the Auto Meter Pro-Comp Lite 2-1/16" gauges fit. This will also save you about $300. But I would not recommend the Gauge Pod set with the Marshall Instruments Gauges. I bought 2 of these Craven Speed Gauge Pod sets with the Marshall Instruments Gauges, $600 a set. I will be changing out the gauges in my other R56 since it get some weird fluctuations in the temp gauge and I have now deemed these gauges as UNRELIABLE. What is even more disappointing as I have purchased multiple Craven Speed parts for my mini, and when the rubber hits the road, it was crickets with my issue. I am pissed that this car has sat in the driveway for almost a year for fear of oil pressure when it was never the problem, just faulty gauges.

If you have access to a 47 ohm - 100 ohm resistor you can easily verify the gauge is OK as follows:
- Disconnect the signal wire from the gauge.
- Install the resistor between the signal and ground connections on the gauge.
- Connect 12V Power and Ground connections to the gauge.
- For gauges with Type 1 or Type 2 sender: 50 ohms ~ 45 PSI, 100 ohms ~ 90 PSI.
- For gauges with Type 3 sender: 50 ohms ~ 90 PSI, 100 ohms ~ 70 PSI.
Most issues are due to incorrect wiring or sender hookup. Since the gauge is dropping to zero, could this be a grounding or wiring issue?

Good question, but sorry, not really an option.

I run synthetic 5W-30 high mileage motor oil currently. I have tried Castrol, Havoline, Valvoline, Penzoil, Mobile, and of course, the most expensive oil I have ever purchased, genuine mini from the dealership in Sacramento. None of which I kept in the engine for more than 100 miles trying to see if any of them made a difference. Yes, this is getting expensive!
The riser for the mechanical gauge supplied by Cravenspeed for the gauge pod accepts the original oil pressure sending unit. So it basically stays in the same location. No oil pressure warning light present. But this has me spooked so the car does not get driven.
I guess my next adventure is to drop the pan, again... and R/R the oil pump.

Looking for ideas. I added the Craven Speed Gauge Pod set to my Cooper after I did the last timing chain/guide replacement. These are cool, but I noticed that after my car is warmed up and driven, when I come to a stop or park, my oil pressure drops to 0 ( zero ). If I tap on the gas, is shoots back up to about 20psi. So, since my car has 140K miles and this is the second timing chain set, I decided this weekend to buy new cam sprocket bolts, remove the new timing chain set and do the Oil Pump drive chain kit. Mine was definitely worn, probably a good thing to do each time the timing chain and guides are replaced. But, it didn't cure the problem. I do have to say, the oil pressure gauge needle is more stable when it has pressure. before it kind of hopped around a bit.
If I am getting over 40psi when cold and averaging 20-35psi while driving, do you think its an oil pump? Never got an Oil light and still don't. I had to replace the Oil Pressure sending unit because it was leaking, so its fairly new.
Any suggestions would be appreciated.
the oil filter not seating / sealing correctly in the housing? (MINI filter?)
bypass valve or drain valve in the oil filter housing defective?
What viscosity oil are you using?
I presume the oil pressure sensor for the gauge is at the oil filter housing - or is it somewhere else?
