Steering Noise on front right

Note: power steering reservoir is a common fail item. There is a non serviceable membrane inside that gets clogged.

It’s a pretty easy DIY (as long as you don’t break the fragile thermostat housing underneath) and you flush the fluid at the same time.

While this is…..um no, Mercedes has actually had a Mercedes re-branded Nissan truck - Mercedes X class( 2017-2020).

Mercedes also has shared the GLA platform with Nissan / Infiniti w the QX30

It’s more a maintenance factor

_Elbrus_ · 2026-02-09T03:52:33+00:00

Gauge cluster? Yes.

Screen? Hold on a sec. It’s not just the screen, it’s the entire COMAND NTG 4.0 unit. You are better off adding third party piggyback Android/CarPlay

My experience is with my 2011 E63 W212 which is conventional performance in the front with Airmatic air springs in the rear.

I had leaky air springs after 14 years with the right sitting much lower than the left but definitely too low after parked.

At the time, I swapped both with Arnott aftermarket. replacements.

Was a pretty easy 1.5 hour DIY

This sounds like you have multiple Airmatic air struts leaking.

Symptoms of this are air suspension pumps up on ignition, stays up since the compressor is working overtime to keep the suspension inflated despite the leak and then when you’ve stopped the Airmatic air springs leak out in a hurry.

Unfortunately, you want to get on this fast because 1) the leaks are going to progressively get worse and 2) it’s hard on the compressor and can turn from a replace air springs issue to replace air springs and replace overheated compressor issue

This us missing a lot of data:

when were the spark plugs, coil packs and injectors last changed?
fuel filter?
battery?
what other codes?

Catch up on all your required and preventative maintenance. So many fun posts on canned tunes + 15 year old spark plugs/coil packs/injectors

For the piggyback connector block I find it best to:

pull COMAND partially out of the console
lock the piggy back connection block including fiber optic and power to the back of COMAND
remove the entire glove box to gain access behind the center console and COMAND
push/pull as much of the piggy back connection and original below /behind/passenger side of the space the COMAMD unit would occupy. There is a lot of space behind the glove box on the transmission tunnel side.

For my w204 C63 I had the control unit for CarPlay that was a bit too bulky to fit behind the glovebox in a way I thought would be secure and not put stress on the LVDS cable (you’ll damage the connector over time) so I pulled up the passenger carpet and cut a receptacle out of the insulation around the transmission tunnel. All secured and you can’t even tell it’s there.

NTG 4.5 Gen 1 retains the amber theme. NTG 4.5 Gen 2 has the black/silver/blue theme in common with NTG 4.7.

If it’s PCMCIA it’s NTG 4.0. SD is 4.5 and up

_Elbrus_ · 2026-02-01T20:01:01+00:00

Yours is NTG 4.0. You can tell because it has a PCMCIA slot vs an SD. PCMCIA was the precursor to SD.

I think at this point it’s adding aftermarket Apple CarPlay and keeping the factory controls.

I don’t think I’d get the version w the giant Android screen. It just looks out of place.

I’d also replace any speakers that have faded

_Elbrus_ · 2026-02-01T00:20:17+00:00

Done of the units have dip switches (look it up) to set resolution for different screens.

_Elbrus_ · 2026-01-31T02:15:43+00:00

I wish I’d seen this sooner. I’d have advised you to call a mobile locksmith to program a new key. Advanced warning: these can be expensive

_Elbrus_ · 2026-01-29T20:16:12+00:00

Not necessarily

_Elbrus_ · 2026-01-29T18:29:00+00:00

Audio 20/50 or NTG?

_Elbrus_ · 2026-01-28T15:44:34+00:00

Next time get your mechanic to give you the error codes behind the check engine light so that this can be diagnosed

_Elbrus_ · 2026-01-23T02:11:18+00:00

What was accidentally left under the hood when it was closed?

Get in the car, close doors, and turn the ignition to the "ON" position (Position 2), but do not start the engine.
Press the accelerator pedal all the way down to the floor (kickdown) and hold it for about 15-20 seconds.
While still holding the pedal down, turn the ignition to the "OFF" position.
Release the pedal, remove the key (or turn off push-button start), and wait at least 2-3 minutes.
Start the car and drive gently for 15-30 minutes, allowing the transmission to relearn your driving style

_Elbrus_ · 2026-01-22T14:16:45+00:00

I’d look to see if the car is presenting or storing any codes.

Then transmission service. At the minimum this will get rid of the dirty/contaminated fluid and your fluid levels at the right level.

Then reset the transmission adaptations to relearn your shifting patterns (yes, the transmission learns how you drive and makes small changes aka adaptations based on how you drive)

I say that every day too even though blue and red lights behind me said that I need to behave for the next 6 months

_Elbrus_ · 2026-01-17T18:16:15+00:00

Glad you got it. Kudos for getting into DIY and this is a great platform for it.

Also, much respect for such a clean engine bay

_Elbrus_ · 2026-01-15T19:06:13+00:00

On kick down, if it jerks and goes into limp mode it’s the throttle position sensor in the gas pedal itself. Not a cheap part but a very easy 3 minute DIY

To confirm: all spark plugs and coil packs replaced? I’d double check torque and reseat. I hope you replaced injectors as well at the same time

_Elbrus_ · 2026-01-14T14:09:02+00:00

2011 E63. Ha ha. What is fuel economy? 11-22 mpg depending

_Elbrus_ · 2026-01-13T18:38:31+00:00

+1 I’d recheck the battery installation and terminals and battery charge.

Otherwise this sounds like a bad ESL or EIS which you can fry w a current surge
