This may be of interest to anyone thinking of buying a facelift W221 S350L BlueTec (or for those who are just curious)

I bought my S Class on 1st October 2021 after recently selling a 2013 SL350 and making £7k profit (which is a nice amount to be able to offset against repairs/maintenance for a while on the W221)

Here are details of the car and what I've spent on it in 2 years (to 30th September 2023)

First of all some pics

I purchased this car for £15k on 1st October 2021 from Praters in Leighton Buzzard:

S350 Long Wheelbase Bluetec Diesel, Registered 30th December 2011 (wow, just 2 days short of being a 2012 registered car)
Designo Diamond White with Black Passion Leather interior
42,826 miles (Current Mileage = 60,529)
2 Previous Owners
Full Mercedes Benz Main Dealer Service History
12 Months Warranty
£15k+ in Factory Fitted Extras:
- Reversing Camera
- Front Seat Memory Package
- Front Seats Comfort Ventilated
- Panoramic Glass Roof
- 20” AMG alloys – 5 Twin Spoke Design
- Ambient Lighting
- AMG Sports Package
- Driving Assistance Package (with Distronic Plus)
- Harmon Kardon Front Seat Entertainment Package
- Diamond White Metallic Paint
- Passion Leather

I planned on keeping it for a while and wanted to maintain the FMBSH so I took out a 3 year Service Plan (Services B, A and B) which was really good value as the next service due included Transmission Service

It was in fantastic condition and everything worked as it should. I did originally de-badge the car and changed the radiator grille to a different style but after a while I decided to get the car back to original so I bought a new original grille and replaced all the badges

All the parts I've bought have been MB original (except brake parts which were Brembo - which I believe were fitted when new). The Services were done at Mercedes Benz, Maidstone and the repairs done by Mertec in Rainham, Kent (a Mercedes Specialist). Here's the rundown:

Maintenance/Repair:
Service Plan (3 x Services: B/A/B) £1,800
Main Battery £158
Spring Links x 2 £756
Michelin Pilot Sport 4S x 5 £1,157
Nox Sensors x 2 £0
Adblue Control Unit £559
Lower arm bushes x 2 £205
PCV Valve £215
Thrust Arms x 2 £537
Airmatic Suspension Pump £461
O/S Wheel Speed Sensor £193
Steering Angle Sensor Rod £73
Engine & Gearbox Mounts £552
Brembo Discs & Pads All Round £609
Total £7,275

Cosmetics:
Cover Rails (Sill Plates) £226
Front Radiator Grille £508
Smart repair (Stone Chip) £150
Wheels Powder Coated £300
Consumables (Cleaning etc) £250
Total £1,434

Running Costs:
Diesel £3,018
Tax (2 Years) £515
Insurance (2 Years) £616
Total £4,149


TOTALS
Maintenance/Repair: £7,275
Cosmetics £1,434
Running Costs £4,149

Grand Total £12,858

The Nox sensors were supplied and fitted free of charge by MB Maidstone as the originals failed following the Diesel Software Update they performed. They were going to charge me for them but because the car had been serviced every year since new by a Mercedes Dealer, they eventually agreed to replace them without charge. During the software update it came to light that the AdBlue Control Unit had been removed. An "AdBlue Delete" had obviously been carried out prior to my ownership. The car would now not start until a control unit was refitted (which the dealer supplied and fitted). The "missing" AdBlue Control Unit was not noticed on MOT test or previous services by MB Dealer!

There may have been some other costs which I can't remember, but that's a fairly accurate summary I think (please let me know if you think I may have missed out something)

I'm hoping that the next couple of years aren't going to be as costly as the previous two because many of the parts will not need replacing for many years (fingers crossed!). Therefore this is not a typical "cost of ownership" scenario over a two year period. Future costs could include AdBlue tank, Airmatic Suspension Struts, Distronic Plus Radar Sensors and other electrical parts. Fingers crossed for now though!

Feel free to comment or ask any questions.

Cheers.

Spending about half the cost price of the car on repairs and maintenance in under two years seems a lot to me. Might make me think I'd bought the wrong one unless it was cheap enough......

It certainly is a lot and I'm hoping that the next few years will be kinder on my wallet!
 
It does seem to have been rather expensive, but your breakdown is a bit skewed: in the Maintenance/repair, if you take out the tyres and the brakes (which are consumables) and the Adblue unit (not the car's fault ;) ), then you get to £4950. Which is more reasonable.

But of course the money's still been spent . . .

And at the end of the day, for price you paid + your upgrades, you've got a very nice car . . :thumb:
 
One of my fav S classes and you take such good care of it! I love the Diamond white colour :)

Things can add up very fast. I haven't done a proper calculation on how much I've spent on both my S classes but I do have a rough idea.... Lets just say, I could have had another nice car but I'm not complaining as we all know this cars are not cheap to maintain :)

I love your S63AMG! It is absolutely amazing and I know you've spent multiple times on it what I've spent on my S350.

I'm retired and just wanted a reasonably economic (?) S Class to enjoy and care for.

Thank you! :)

No such thing as a cheap S class, AMG or AMG pack, they still can cost a bit 😁 but like you said, now it should be kinder to your wallet :)

That's a very interesting report, well done. I've a 2017 W222 S350D and its giving me food for thought about what may very well lay ahead!

How much of the costs you incurred were to bring it up to scratch at our best the start of your ownership, as opposed to stuff that needed doing later on?

When I bought it I knew the battery, lower arm bushes, brakes and tyres would need replacing within a year or two. The stuff that came to light later were the compressor pump, engine mounts, Thrust arms, speed sensor, spring links and PCV Valve. The airmatic pump was a surprise as it only came to light that it was missing when I had the official update done and it became obvious that the adblue had been "deleted" at some point before I purchased it.
 
I meant the Adblue control unit was a surprise, not the airmatic pump
 
Very nice. That's quite affordable in my opinion!

I've put about 4k of fuel in my daily E320 over the last 2 years as well, but so many more parts...

I'm sure that if you went full DIY, the OCD would catch up and it wouldn't have been any cheaper 😁

I currently have two E class (S211) with the older 320 variant of the V6 diesel, and have grown quite fond of this engine. Would almost dare say it's the best modern diesel out there (if you drive through the whole range like it was meant to at least).

Eager to get my hands on a middle of the road, cheap and reasonable, 2011/2012 long S or CLS Estate with this 350 diesel 😍
