ML 350 engine light - help?

[M5V8 337]

so the wife's ML350 (2006) Mercedes engine check light came on.

I've had it scanned and they have told me the codes came up were 0750 & 0746

I can't find anything online. Anyone have a mercedes to english translation?

[M5V8 337]

couple more points. Car runs fine. Had recent service inc gearbox. On the wknd the check light went out. Weirdly.

But i suspect thats temporary.

what I have found:

P0746 Pressure Control Solenoid Performance or Stuck Off

P0750 Shift Solenoid A Malfunction

Anyone know what these mean? are these even correct?

It is possible that the error codes are a temporary thing. did you have the gearbox flushed with a flushing fluid?

No idea. It was done by dealership. Nearly $600 so better have!

I might enquire.

Cheers.

722.906 7sp transmission...

Does it shift smoothly at low speed? If you slow down to a crawl, then accelerate again?

Did the dealer replace the gearbox sump gasket and the filter? (For $600 I sincerely hope they did!)

[qube 3570]

cost me $600 at coutts mercedes just for trans fluid service.

[M5V8 337]

Yeah that's just the thing. It drives great. No shifting problems. The only thing is sometimes it makes a odd noise when putting in park.

I'd be more concerned if it was giving some indications.

I actually like driving it. (Just quietly)

Shh!

I suspect it could be as simple as marginally low fluid - that would give the two codes you're getting.

Take it back, say you've been getting this issue since they changed the fluid, and ask them to check/top up.

There are other possible causes, but that's the one which is most easily checked.

Yeah fair call too.

Thanks

After taking this to our local mechanic for a scan 3 times, with several different sets of codes displayed and $127 later we have been forced to take it to the Mercedes dealership.

wait for it.

Cracked intake pipe. $3500.

Cracked intake pipe. $3500.

What the hell are M-Class Mercs' intake pipes made of??? Pure platinum??!!!

Kind of scary that you can pick up a whole M-Class for not a lot more than the price of a new intake pipe... no wonder they're so cheap on TM.

Got a part number for it?

[M5V8 337]

Apparently there's a leak in the intake system somewhere. Of course Mercedes response is to replace the entire system.

Crazy.

Luckily I don't really care. it's under warranty so cost to us is negligible.

But $3500 is eye watering. No wonder the dealership is so flash.

Wise words kiddies. Get that warranty.

Sounds like normal #merctax to me, shits crazy. Be thankful its not got an AMG badge on it.

Small protip too, the dealer makes f**k all margin on parts, the mothership really puts the squeeze on them. Not much money in genuine parts these days.

That must take a load of with it under warranty on a similar note Clarkson forked out 1,200 pounds for the replacement of one coil pack on his merc and May and Hammond give him stick about it on last nights episode.

[KwS 2425]

Try doing the coil pack on a V12 merc, its all combined into one big unit (per bank) for a sweet sum of $3600+gst or so each. Nopenopenope

Bosses 2011 AMG CL63 needed new rotors and pads.. cost $12,000 heh

$4500 NZD just for the Front Rotors alone

i should see what the carbon ceramic brakes on the SLS at work are worth, just for giggles.

[KwS 2425]

Lawl, the front rotors on the SLS are a touch over 8K+gst each. Best not use those carbon ceramics very often.

So there's an end to this story.

$3500 of replacement intake system. Next day the light comes back on. Back to Mercedes it goes. They worked out there's a fault MAF sensor.

Light hasn't come back on since.

Now.

Question is. Was that the fault all along?

[_ethrty-Andy_ 2136]

So who paid the $3500 for the new intake?

[charles28 137]

ohwell, even if it wasn't the intake, it was cracked right? so was probably good to have it replaced anyway.. that is.. under the warranty.. if I had to pay $3500 for nothing i'd be quite upset.

[M5V8 337]

Breakdown insurance. This whole thing as cost us $250 excess.

luckly.

yes. I guess we have to trust mercedes that the intake was infact cracked, as they couldn't tell me where or were prepared to show me.
