When will you sell your X5?

Over the years I discovered Mahle Behr radiator to be as good as BMW OEM radiators, at least on the M52, N54 and N62 engines. I also tend to stay clear of OE electronic components but I'm wondering if I'm making a mistake here by making a swiping dismissal. One strategy I use to keep costs down is to leverage FCPEuro's lifetime replacement guarantee even if their prices tend to be on the higher side due to their business model.

I would be happy to help. I'll answer here your question but to not cloud or misdirect the thread my email is [email protected].

In most cases, Lemforder, TRW, Corteco (in that order) are fantastic choices for OE suspension components across BMW models. All three of those companies provide their services to BMW OEM to build suspension components for them. While the standard of testing or QC of those companies isn't maybe the same standard as branded BMW OEM parts I can say it's not very far off.

In regards to cooling system components, depending on what parts you are replacing, Graf, Pierburg, Geba have high quality / BMW OEM supplied parts for lets say waterpumps & such. If speaking about hoses, I have very good experiences with Gates but usually stick to BMW OEM unless the price difference is outlandish. Expansion tanks, ALWAYS BMW OEM. Radiators, Behr, Mahle, or OEM as I've had a few QC issues with Nissens even though I believe they are a BMW OEM supplier for some models.

I usually run BMW OEM electronics. In regards to FCP Euro, we have an account with them but rarely use them. I understand the comfort level with their warranty on parts as a hobbyist but as a repair facility we don't use them often. I will say, FCP Euro has a fantastic wholesale department & sales team.

I always use OEM gaskets unless we are on a budget. For instance, I've used 4 different companies offerings for OFHG's as well as cooler gaskets & they ALL leak prematurely. BMW OEM QC crushes the competition when it comes to very small margin for error parts like a rubber gasket or seal.

Oil filters, Sometimes Mann, Mostly Mahle, Rarely OEM (Unless it's part of one of our larger services like crank hub or rod bearings or if requested.).


I hope this helps

EDIT: Sorry if I missed a company or two that make quality parts. There are so many out there and these stand out to me off the top of my head.
Notable mentions - URO, Textar, SHW, VNE, LUK, Continental, Dayco, Sachs, Bilstein, Hengst

Clearly many, many parts are being made still for our E53s, and others are not. As of this past Wednesday I'm sporting a cool Trifecta of lights and have been researching causes and fixes. Thankfully there is lots of great info on this, and other sites. Much of what it could be is very much available new, but it doesn't seem that the DSC module and compressor are being manufactured any longer. I've managed to find a few in stock, but they are crazy money now.

it seems strange to me that so many parts on our cars have multiple manufacturers, but a few don't seem to be supported at all any longer. Fortunately, if I'm lucky enough it will be a wheel speed sensor, or steering angle sensor, both of are still made by several mfrs.

That said, it is a pretty standard Bosch DSC unit from that era and I wonder if I can get the same model from audi, porsche, etc. and flash it. Assuming someone still mfrs these things.
