Started my sunroof resot today.. Got a buch of debris and a few lbs of roof insulation out. Took the slider to an upholstery shop to be recovered, hopefully they can salvage the original material...
HUGE shout out to Mafia Don for the excellent DIY write up!
Yanked the front bumper to attempt to repair, too far gone and the side clip that slides onto the bracket by the wheel well was broken off. New one on order, $177 + 135 S&H. It'a a new aftermarket bumper, I'll post an update when I receive it to comment on finish and quality.
I had PO301 to 306 codes and so I changed all 12 plugs and boots. Plugs are 60K miles old so it is probably time anyway. Changed coils on 1-6, based on misfire codes. Also changed coil on #12 since it is difficult to get to. You have to loosen the wiring harness tray to gain easy access. #11 was done by the dealer a few years ago. I replaced #10 because the tip broke off when I removed the boot. Seems to run better , but have not driven on the road yet. Will watch to see if codes come back.
May order a new MAF Sensor since I also got a PO170 code.

It may be too late, but I did the same with all 12 coils. However, I found the identical Bosch coils at amazon.com for half the price the dealer wanted.

I think I bought my coils from Autohaus several years agoat $50-55 each. Much less than dealer. I just found the MAF on Amazon for $110. Finding inexpensive parts is almost as much fun as searching for a replacement W140, C140 or R129!
I probably need to replace both intake air filters. I can still feel a little shaking in the seat at idol. I am sure it is time to finally replace the engine & Tranny mounts.
Distributor caps and rotors, new wires, plugs and ignition coils, cleaned out the EGR, throttle body and MAF and still had energy for a bit of interior detailing.
Tomorrow, renew the hydraulic fluid in the reservoir and get an alignment.
Since the new bumper didn't fit, I cobbled together a solution to get the old one back on with some gorilla tape and a metal bracket...
If anyone wants a FREE bumper, you're welcome to come and grab it if you think you could make it fit. It's doable, I just don't have the skills or resources to make it happen.
Finished repairing the Duovalve with new seals and gaskets. I was hoping to fix a problem with the rear seat air pushing hot air when the A/C is running. Oddly, one of the vents blows cold A/C now and the other blow warm air.
I ‘ve driven my ’94 S500 cpe for 20 years . . . and it’s now 25 yrs old. It’s been the most reliable Mercedes that I’ve ever owned with maintenance costs being minimal. After I retired, it has spent a lot of time in the garage for lack of driving.
So it was time to give it some love . . . as this thread says.
1-Started with a radiator flush using just distilled water.
2- Oil change + filter
3-Replaced poly-belt
4-Replaced spark plugs (apx 10+ years old!!)
5-Replaced both side – distributor caps and rotors (apx 15 years old!)
6-Replaced both accumulators
7-Found and repaired ohmic connection to Aux Fans . . . no low speed
8-Replaced windshield washer fill tube and grommet
9-Replaced all four tires . . . 12 years old set
And here’s what it looks like today . . . still in the garage . . temp is 95F!
On my '94 S500, plugs, wires, ignition coils (MUCH easier to do if you take the left headlight off the car), distributor caps and rotors. The car only has 134K on it but, as far as I can tell, the coils and wires were original. Mileage notwithstanding, they're STILL 25 years old so it was time for a redo.
Tomorrow a fresh oil change, a full detail then into storage until Spring. She and my '95 SL320 have never seen a single snowflake and, as long as I hold the titles, never will.

I have a 96 S420 with over 202,000 miles,I'm gonna have all (4) BILSTEIN B4 OE REPLACEMENTS shocks installed and a pair of brand new rear springs installed tomorrow at an independent Mercedes Benz shop I've been dealing with....
Ever since I got my 2nd coupe on the road, something felt loose in the front suspension. I had replaced everything worn, including the idler arm bushings. I tried saving a little money, and rather than buy OE bushings from Mercedes, I went with a less expensive option. Lemforder bushings are...
Dear Gurus.
First off, I would like to thank all the contributors for their amazing work over here. I bought my W140 a year ago and did over 35K so far, and every single issue I had, I found the solution over here!!! Thanks!!! (y)
Now to the problem:
My 99 S320 (165K Miles) has been having...
My life in my previous home state was a bit different. I was a career bachelor. I knew many people and where to get things done. Since moving, the birth of my first who had very bad digestive issues and then my second I have not, suffice it to say, made the inroads in my new home town. So here...
Hope everyone is doing well and the card even better.
TLDR
99 S500 (built in 98 I think because of rectangular headlight shape, a little over 125k miles) help with exhaust. Do I need all 4 cats or can I just keep 2 if so what is situation with O2 sensors.
