Hi - hoping someone can help.

Mercedes Roadside Assistance have told me I need a new Ignition Coil for my 2016 w205 C63 but Mercedes have none in stock ... and apparently the wait could be several weeks (!!). Unhelpfully, the prima donnas in Mercedes parts department are refusing to give me the part number but the Roadside man did give me the part number of A 177 906 02 06.

When I Google this part number it comes up as a GLC part number - so my question is ....... would anyone know if this is the correct part number for my w205 C63 too (I know they share some parts). if so I may have found one online which will save me a multi-week wait.

Many thanks in advance.
 
Check MB NEWCASTLE OR EDINBURGH would be my 1st port of call

@ iggu, could I ask what is your mileage when the coil started to cause problems? 🤔
 
Thanks for the replies folks. Here's what happened. Car is on 36700 miles and is a 2016 C63 Saloon. Driving home in slow/medium traffic the car suddenly began to shake, the amber engine warning light flickered, then went solid, then the car went into limp mode. The fault codes are:

P030022 Misfire Detected
P030485 Cyl 4 Misfire

The Roadside fella just logged these stored fault codes and said "need a new coil" straightaway. Then he said "you can't get any, global shortage" and he showed me the red status symbol on his laptop which showed they are out of stock across the MB network. I rang MB Warrington and MB Newcastle - and there does seem to be a shortage with no ETA for new stock. So theoretically the car is beached. However ... while he was here the car ran perfectly, no fault codes thrown up, very smooth.

I found one or two new, OEM ones online showing the part code above - but am just trying to confirm the part code is the right one for my car. Not proving easy to do this.

Meanwhile .... I have made 6 test-trips out in the car since, mostly gentle cruising with a couple of full-beans redliners. Nothing. Running perfectly. Full power, nothing untowards.

So ....... could the misfire be a one-off? Should I ignore it and see how it goes? Could the "need a new coil" just be a bog standard response? Could anything temporary (eg bad fuel) cause such a misfire?

Any help would be GREATLY appreciated. I don't minding spending the £££ on a new coilpack from a non-MB source if it fixes it .... but I don't want to go down this route if it isn't necessary.
 
If it's running now, maybe it needs a software update? Hopefully Jobsworth might chime in on some advice, he is extremely knowledgeable and knows this engine 😉
 
Just to muddy the waters, different Part numbers on this EPC.


As above, remove your faulty one and cross match the Part number.
Good advice from badgx above waiting for Jobsworth's input. He is an experienced MB specialist and owns this particular car himself.
 
A little research into who makes the part for MB might help you track down the replacement 👍
 
 
Call a dealer (or two...) and get them to give you the P/N. It's a joke that your local dealer refused. It's not like it's a big secret.

FWIW there are several threads on the US forums that list 177-906-02-06 as the correct P/N. There is one available on eBay here: MERCEDES-BENZ GLC X253 Ignition Coil A1779060206 NEW GENUINE | eBay (though it's in Europe so will have import duty etc.)

ignore the above p/n on second look.

These are on backorder. I had two in stock but I helped the new member on that other thread out with one, so I have one left. The new part number is A177 906 9500. The old part number is A177 906 4***The A177 906 4***s are known to be trouble

Don’t waste your time with secondhand of the older part number. That was the problem the OP in my linked thread had.

Ok thank you Jobsworth. Would you suggest parking the car up until I can track one of these new parts down?
Appreciate your input here.
 
Where are you based?
Cheshire - but would happily travel to get it sorted.
