Beautiful car 👍
 
Of course I like the interior - same colour scheme as my CLS - but that version of the S class is for me the best-looking of all; like the W140 back in the day, it has real "Get out of my way, peasants" presence.
 
Glad to see you back. Love seeing what your doing to your cars. Thought I was OCD, but I'm the equivalent of one of the East European car wash boy's with the dirty rag that does everything next to you:mad:👍
 
WOW! Sam, what Epic motors! 😎🙂👍

Thank you! :)

I really like light coloured interiors, it was the main thing that stood out when I saw the car for sale.
Haha :D, I do know what you mean, they do have a lot of road presence :)

Thank you! You’re very kind but there’s still lots of room for me to improve :)
Plus, my engine bay is not as shine as in your S63AMG :D

I have no words, just amazing. I thought my old was bad :oops:

😁
Thank you!
 
I watched a video from Exotic Car DIY regarding a oil pump solenoid sensor and how it actually helps if you disconnect the sensor.
I done some more research and I thought I'd disconnect the sensor on my S63.

I haven't driven the car as it has been sorned and will not be used until summer time.

For anyone that has an M157 or M278 engine, this might be useful information's and i thought I'd share it here too


Missing oil sensor:
There is a oil tap/plug on the oil filter base to use for a manual oil gauge or a sensor.

That is where MAX pressure is found near pump. MIN pressure is found all the way to rear bank1 where HPFP only gets what pressure is left over.

Meaning the pressure at filter is only a partial overall view. There is a pressure leakage right at timing cover that has no gasket and no silicone... we have not figured why MB wants no oil seal at timing cover.

> Proof in the pudding:
From the oil filter location you can chart pressure vs. RPM to evidence how ECU is forcing low-pressure below 3500.RPM.

The engine PDF description almost read nicely... Daimler wants "warm up the oil"....but there is NO FEEDBACK CONTROL to limp-mode when cheap valve gets stuck on low-pressure. It blows-up the engine piston/crankshaft bearings RIP.



managed pump pressure...

Now we know why the piston rings get stuck with burned oil carbon... Then it causes high blow-by crankcase pressure that blows oil out of everywhere possible: seals, plenum, vacuum pump, "oil-in-harness" CPS, ...

The design idea to warm up is all right and if it was well developed - When quarts of oil get vaporized you'd think it is hot enough so they can quit driving on low pressure to warm up the engine.
This feature is like the "Job of a summer intern" that never got completed - IT'S UNSAFE!

There is s big unspoken design gap about the VVT gears. They rely on pressure to work well. Low pressure virtually disablestge non-ratcheting tensioners and VVT that has to lock in neutral. That's the genesis of engine rattle wear.

> Idle quality:
Listen to the idle quality improvements with legacy oil pressure !!
The camshafts sound is quieter
The HPFP is much quieter
The tensioners hold the chain tight and
The RPM is evenly smooth instead of up/down
The cold engine warm-up high-idle is much shorter


> Closely matched Trims:
Trims are always somewhat matched to engine else a CEL flag is raised. More fuel means more power, that what we get here! Better burn allows more fuel delivery at lower RPM.

Here is how...
The smoother camshaft timing driven by the tight tensioners and the pressurized VVT gear allows the HPFP Qty valve timing to be exact in regard of 3/4 lobes showing up with minimal variations.

This means fuel pressure is well regulated not just averaged. In turn that allows for injector trim to chart better fuel maps from cleaner lambda sensors.
It does take about 1000Miles to reach that stage of improved engine driveability. Meaning improvements happen gradually starting from the first 10Miles test drive.


> Unnecessary chaos:

This feature introduces so much drama that its impossible Daimler isn't aware of it's negative impact with zero benefit besides service needs.

This is where the sensor is located..... [ not my pic ]



This are the results of disconnecting the sensor [ forum member Kevm14 from MBWorld ]

I cannot believe how snappy it is on a free rev right from idle. This translates to the rest of the improvements which I will summarize.

1) The part throttle response/torque delivery from a low RPM is totally smoothed out and stronger. I'm talking like 1000-2000 rpm situations where you roll into the throttle. It was unsmooth and would kind of surge before. I even threw a wastegate vacuum harness at it as well as a vacuum pump check valve, thinking that might help. Nope, it was the damn VVT not reacting right to low oil pressure due to the oil pump valve bleeding pressure at low RPM.

2) Idle quality is improved in general. It's just smoother.

3) Revving response in park/neutral as the video shows is extremely crisp. I can't believe it actually.

4) And here's one that really blows me away. I thought I had MCT clutch chatter, like when slowly moving off the line, up a slight hill or something. I just figured, hey, it has 102k on it, it's going to chatter a little bit. Well, the MCT engagement is COMPLETELY smooth now. Like I said, I am blown away. Forward, reverse - it's totally smooth. I was convinced it was the MCT! It was just the engine running unsmoothly.

5) Actually the transmission shifting itself seems smoother to me (up and down).

Now do I think this really adds any peak power? No, because the oil pump valve would already be closed in those situations. But for all the situations where you are at part throttle, especially at lower rpm, this made a huge difference. Oh, and no CEL. Engine sounds healthy and strong. I have zero concerns about any downsides to this. I think it is all upside, incredibly.

Alright, now someone else try it! You're welcome in advance for bringing this to the W212 AMG forum, even though it seemed to be known to the M276 community already.

I couldn't stop driving it when I was done.

I missed this post Sam, just read it now. Have already unplugged mine as you can see from my other post.

The revs are definitely snappy as I also described this in my thread. I thought my mind was playing games. I reckon the 4 bars enables the cams to adjust much quicker. I also like the idea of the oil sprayers in full time employment, should help with cooling and lubrication. 🙂

Sound wise I think its slightly quieter by a very marginal amount. However having said that my engine is quiet anyway to start with. I have taken some before and after sound clips, using a directional Rode mic, will try and upload later.

Definitely warms up a tiny bit faster than before which is an improvement, which means as I can drive off much sooner from cold. 🙂👍

My friend said the same thing about the revs and he noticed the gear changes seems to be better also? Comparing the smoothness of the gearboxes between my S63 and the S65, I prefer the 5 speed gearbox 🫣. I know some might not agree. Obviously the gear box in the S63 is faster but I love how smooth the 5 speed box is.

🤣🤣🤣
Looks like it's worth unplugging that sensor 😁
 
Wow it looks great here!
 
Not much to report apart from getting a new plate for the S63AMG.

I have a few plates that say OCD as a joke as most of us car enthusiasts seem to have a bit of an OCD when it comes to our cars :D
The current plate that’s on the car also says OCD but I wanted something different.

The plate for the S65 says V12 I OCD and I thought if I could get a similar plate for the S63, it would be quite cool to having matching plates for both cars.

After contacting DVLA and being told that the plate was available, I said I was happy to go ahead and buy it.
It’s not that simple as DVLA auctions any plates that have not been for sale before and there’s no buy it now price.

I got told I’d have to wait 6 months until the plate would go on auction. 3 months later, the plate appeared on their website and I had to wait another 3 months until the auction would go live.

I was a bit worried if I’d be able to buy it as other people might now be interested in buying the plate.

The plate went up for sale and after 6 anxious days, the plate was mine :)

I haven’t assigned the plate to the car yet but I will be doing that soon.

Here it is



And the S65



The M3 plate

Brilliant! Love um. Even the BM.
😉🙂👍
 
OCD, pretty unusual name, thought your name was SAM :banana::mad::banana::);):oops:

Sam aka Mr OCD 🤣

Given the plates are all OCD, I’m amazed they’re all incorrectly spaced…….🙄🤣

I guess you could say I'm not a true OCD person 🤣....... In my case OCD stands for Obsessive Car Disorder 😁
 
If you lived around here you would not do it...i guess the cops don't have as much to do around here!!..A silver C Class owning neighbour of mine is back on stock 19 plates (it was something like K834LES)....spaced to look vaguely like his name K Beale's. He got stopped a while back and warned and the DVLA was told .. .got stopped a second time.... letter from the DVLA... plate confiscated. He could buy it back....but unless he miss spaces it, it looks like nothing anyway....so now just sticking with stock plates. They can do it so easily as you don't pay to ever own the plates, just use them so the DVLA still owns them and can take them back in such circumstances pretty easily.


....... and before anyone says its a rare occurrence... thats true.... this is only the second time I've heard of it happening and the first time was back when I was working in the trade 20 odd years ago.
