What an awesome M5 shopping experience! It's sad to see your old M5 go after all the work you've put into it, but it looks like it will be in good hands with its new owner. And the new M5 is my favorite color combo! Looking forward to seeing what you do with it. Will you keep the Supersprint, or go back to Eisenmann? I'm guessing the latter because of TuV.

Haha I knew it wouldn't be long until you sold the silver M5, but you've found an equally stunning replacement! It's a bummer you had to have both M5's shipped to you from Italy, those twisty Italian back roads would be so much fun in an M5!

WOW. What a stunning country to look for M5s! I hope you bought them cheap! I'd love to get my hands on one!

Thanks! I wouldn't say it was cheap, I actually think I paid a bit too much but I did like this M5. The USA is full of them, just pick one. :D

Danke! A lot of work went into the silver one and I'm not sure if I'll get that lucky again and own an M5 that was as mint as that one.

Actually, Supersprint Magnum that's on this M5 does have necessary TUV approvals like Eisenmann Sport. I want to run Supersprint mufflers for a while just to get a better feel for them and make a comparison to Eisenmann and decide which one I like better for the long run. Though, I did just discover something on the car that won't pass TUV.

Thanks, Danny! It was shorter then I hoped for, that's for sure. I was dying to make that drive through Italy and then hit the Alps, would be an amazing experience. Sadly, it simply isn't possible since Italy doesn't have export plates and no one is crazy enough to let you drive on their plates through Europe. Shipping with the truck is the only way.

I did a visual inspection on the car and it's pretty much what I expected - typical M5 stuff.

Ball joints on both rear control arms are shot. Front thrust arm bushings are also shot and control arms appear to be original so I have a complete Lemforder kit coming to refresh the suspension. Power steering lines are leaking all over and made a big oily mess. I was expecting diff to be seeping oil because this was common on my previous M5s but it's dry.

Rear sway bar link failed spectacularly.



Then I discovered why are the cold starts loud and why Supersprint Magnum is louder than Eisenmann Sport mufflers which shouldn't be the case.

The car also has a Supersprint X-pipe. Somehow I missed this in Italy and normally I wouldn't mind this because it sounds awesome but this is a no-go for German TÜV. It's an instant fail at the inspection and now I'm trying to source original resonators. But, I might take it to the local inspection station and hope that the inspection guy is not familiar with these cars and overlooks this but I doubt that will work. They are usually thorough.

Supersprint mufflers have been on this car for roughly 15 years since production date reads 2003.



The parts list keeps getting bigger but hopefully first round arrives this week and the refreshment treatment of this M can be under way.

I'm in the UK, which makes Europe only a hop and a skip away!

Minus the purchase problems, a great "European Delivery!"


Sorry you sold the sliver M5 but glad the hiatus was short. Great pictures - thanks for sharing.

I was out of town on a road trip but just got caught up. Sad to see it go for sure but I totally understand. There's a certain level of joy that is only obtainable by restoring, and it's different than the kind you get while driving. Glad you found another quality candidate! The buying process definitely sounds like a nightmare so props to you for sticking it out!

This is how I was picturing everything once you agreed on the price:

There are good deals in the UK as well!

Thanks, Kevin! Glad you enjoyed the read. :)

Thanks, Kiz! The TiAg M5 will be missed for sure, but you are right, there's satisfaction and joy when restoring a neglected car and simply making it run better.

Haha, the dinner did look like that. Didn't have much of an appetite after but was glad it was over.

Great mix of car story, great sights and great food pictures. Thanks for taking time to do it!
Thanks, Z! You and I communicate daily and share our battles. Hopefully we'll properly catch up this summer in Europe!


Last weekend my girlfriend was out of town and the M5 got my full attention.

Started off with the easy stuff.
New wiper blades and cabin filters.





The car came with some sort of K&N air filters and one of them was actually falling apart. I don't have experience with them and didn't feel like experimenting so I chucked them away and went with good old MANN.



New timing chain tensioner.





New oil separator hoses. Old ones were so sticky and soft that you could stretch them like a gum.





New oil cap and trunk struts since the original struts were so weak.





Fresh spark plugs.



Rear sway bar links and bushings.



The ball joints on the rear upper control arms and guide links are toast.



Replaced the upper control arms and still waiting for the guide links to arrive.





Now the big job that I did on Saturday. I diagnosed that the thrust arm bushings were shot with everything else appearing to be original to the car. I decided that the best course of action is to replace everything.

Bought complete Lemforder kit and Meyle HD sway bar links.





Back when I did the overhaul job of the front suspension on my old 530i with a friend, the biggest issue we had was with the sleeve coming out with the ball joint. We wasted so much time on that crap.

This time I wanted to be sure I have the proper tools for the job and I bought off Amazon this ball joint separator.



Which is the same tool as this one, just branded as KS Tools in my case- https://www.ecstuning.com/b-schwaben-parts/ball-joint-removal-tool-20-80mm/008958sch01a~sch/

This nifty tool saved me and worked great with one little modification. The bolt kept sliding so I drilled a hole in the swing arm to keep it place.





Apart from getting 3 complaints for working in the backyard of the place where I'm renting my garage, everything went swimmingly.
Once the ball joint lets go, it's like being shot at and scared the piss out of me. Though it is a satisfying bang. :grin

Lower control arms were okayish but everything else was toast.







Using my trusty torque wrench, torqued all of the ball joints to specification, finger tight for the bushings and then lowered the car - drove back & forth and onto the ramps for the final torque under the load.

This is a good website with torque specs for the suspensions which I cross-referenced with TIS - https://www.how2fixvideos.com/BMW_suspension_torque_specs.html





This was a hell of a job to do in one day. It was a pretty good workout that left me sore and took me about 45 minutes to wash all the filth away that I brought home.

Following this - on Monday I took the car to TUV to see what will they find and how big is my homework going to be.



The car failed the inspection but to my surprise not because of the X-pipe! The list was pretty short and embarrassingly enough the car failed the handbrake test and there was an excessive play in the right rear wheel.

The handbrake was sorta working in the past few days but I did feel it was on the weak side. This was a quick and easy fix by removing the rear wheels and adjusting the little gears for the parking brake shoes and readjusting the cable.

TUV guy wasn't precise with the play in the rear wheel and just wrote it off as a wheel bearing which I thought was unlikely. At first, I thought it might be the upper guide links but after double checking, the play is coming from the lower ball joint. The rubber on the ball joint is intact from the outside but if I hold the wheel at 12 & 6 o'clock there's so much play that I can move the whole wheel just by pushing with my thumb.
This isn't a quick and simple fix but I'll get it sorted next week, I have the parts and the ball joint tool on order and waiting for the delivery.

When I go back to TUV, they'll be looking only into these two things and hopefully that should be it. After seeing the roads in Italy on which this car was driven, it comes as no surprise that the complete suspension is shot. I'll be doing an alignment after I complete the work and probably later down the road I'll replace the struts and shocks, just gotta decide if I want to go with Koni yellows or pony up for the OE parts.

I did get to talk to the TUV guy when I went to pick up the car and he was a really nice guy. He's also a BMW enthusiast who owns E30 M3 and E34 M5 and gave me compliments about my M5. I didn't want to say anything, but there's no way that he missed the X-pipe. My guess is that there was some comradery between car guys and he turned a blind eye on it and I'm super happy that I don't have to swap it out. He himself said that the car sounds fantastic.

This is where I am at the moment and priority stays the same - pass the TUV and get it registered.
Future plans are Vanos maintenance and more general maintenance, refurbish the headlights with Hella G4 projectors, upgrade the Vanos accumulator - the start-up rattle when warm is simply unbearable, etc.

It appears so. I didn't have time to do research. They didn't exactly break up, you can see in the picture that the left one is missing the rubber seal which fell apart when I removed it.
The other one I kept and it looks to be washable and in good condition. Once I do more research on this topic, I can decide if I want to buy another one or stay stock. Thanks, JohnAnthony!

Nice work on getting all that sorted in 1 day! I used a similar ball joint separator and agree they're invaluable. That bang in the end is scary yet delightful at the same time!

Danke, Kiz! This tool is a must when dealing with ball joints. The bang just makes the win more special. :D

Thanks @sreten - Very informative, I found my favorite thread...!!!!!!!!
Thanks, man, appreciate it!

I replaced the rear right ball joint and fixed the handbrake last week, then took it back to TUV and this time it passed! :M5rev:



Customizing plates in Germany is very limited since you have to have 1 to 2 letters and 1 to 4 numbers in that order. I wanted to get M539 but it was already taken and not having enough inspiration at the moment, just added another M. :M5eyes:

Changing the rear ball joints was tricky but the press tool I bought made it super easy. It took no effort to remove the old ball joint and press in the new one.
The tension in the swing arm is pretty strong so I loosened the 2 rear bolts to make it easier to maneuver and avoid putting stress on the bushings. I did so much work on the suspension that alignment is a must in any case.

The tool that I used: Asta A-9055 - https://www.amazon.de/gp/product/B00IJD8YBW/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1











Both ball joints looked intact from the outside, but the right one was totally toast and it was the same with the left one, only that one didn't show any play in the wheel. Always a smart move to replace everything in pair when it comes to suspension.

Got the new rear guide links too. The rubber on ball joints was gone but they were still fully functional.





In the midst of that, I killed the 4 year old BMW battery with short drives. I could've probably recharged it and got more use out of it but having a good battery puts my mind to ease so I replaced it with trusted Exide 100Ah.



Next was sorting out the horrible shifting. I decided to try BMW MTF-LT-2 fluid which I got from my local dealer for $25 per liter.



I have no idea what they put in that poor gearbox but that stuff was just nasty. It came out all dark and smelling like death. Not to mention that it was overfilled and oil started coming out as soon as I removed the fill plug. This all made for one incredibly crunchy and sloppy shifting.

With the new fluid, crisp and precise shifting is thankfully back and now it feels like a proper BMW. Even the cold shifting is pretty good.

Next on the maintenance list were power steering lines. They were replaced at some point but from the looks of it, they used some custom made lines. It wasn't too bad but they were leaking at the PS pump and PS cooler.



Installed proper BMW lines, new reservoir and completely flushed the system.



Then some cosmetic touches.

New wheel center caps.





New hood roundel.





Removed the M5 badge from the interior trim which PO installed for the reasons I can't understand.





Having an M5 badge in a wrong place was really bugging me. Off it went and I used the badge I previously removed from the interior since it looked more fresh.





Secured in place with double-sided tape.



ZHP shift knob.



The famous rear view mirror leak didn't miss this M5. I ordered a replacement glass from X8R from the UK and did the repair on my own. They claim this is a permanent solution that will not leak again. It's fairly easy to replace and they have a youtube video for the whole process.







It worked out great and the mirror is fully functional again. Cost of the glass was $135 shipped.

I treated the car with much needed hand wash and went for a blast down the Autobahn. Man it feels good to be back behind the wheel of the beast.

I smashed the camera on my phone and the pictures are coming out weird, sorry guys for that.







I have to get an alignment done this week and I decided to replace the struts & shocks which will complete the suspension overhaul.
Original struts do feel tired and the rear ones have leaked at some point as there is oily stuff all over them.

Ideally, I would want to go with OEM shocks but they are only available from the dealer and cost stupid money. Koni yellows are half the price and I have been wanting to try them.
I find adjustability unnecessary for my use to be honest and just want to maintain the stock comfort ride. I did get in touch with Koni and recommendation from their engineers is that I keep them in factory setting 0 if I'm pairing them with stock springs which I'm planning to do. This combined with great feedback on the board gives me confidence and I'll order them in the next few days.

Excellent work! How lucky this car was to be saved by you. I still can't get over how nice the slicktop LMB looks. I would have given anything to have that extra headroom all these years, the lighter weight, and nice appearance. :)

Man, it's so damn satisfying watching you replace all this hardware. :)

Lower control arms were okayish but everything else was toast.



I need to replace the control arm bushing on the driver's side again and I'm trying to remember which one required the shock to be raised for nut access. Since you just did it, was it the rear/larger control arm or the forward/smaller one?

Removed the M5 badge from the interior trim which PO installed for the reasons I can't understand.

Put that badge back right now! How else will you know what you're driving?

Good call on getting the proper tool for the lower rear ball joints... the generic c-clamp style tool is a complete hassle to use otherwise. Both of my rear ball joints were shot so it made a huge difference in the ride and handling.

I love how you’re saving all these mildly neglected Italian M5’s, haha.

You have the best playground for the M5 with an actual Autobahn at your disposal.

What options are there for differential bushing removal kits, or is there a kit that does all 7 rear subframe bushes because most kits that do various models of bmw don’t actually say they can be used to swap out the diff bushes on an e39.
