I hope I have put this in right place … so I have a 2020 a35 29,000 miles full service history bought privately …so the management light came on .. on further investigation the garage are saying it requires new cylinder head ! And it’s a common issue on this car At a cost of £5000 + so I then came to this forum for help and see it’s a common problem .. Mercedes have said they will pay 75% but this feels so wrong surely they should be fixing this FOC has anybody managed to get it sorted with Mercedes covering the full cost … advise appreciated

Hi,

How did it go getting mercedes to good will your engine rebuild? I'm currently in contact with a garage now

I agree it should be FOC, I managed to get mine down from £5,400 to £1,400, but still not happy about it. I'm surprised no one has suggested a class action against Mercedes for a car with a faulty Cylinder head.

Hi,

was your car out of warranty when you got this reduced? my car is just under 4, so out of warranty in uk, but only has 33k miles on it. this does not seem like standard wear and tear with how much this has been reported. I was initially pushed back for good will but will be fighting this

Mine was 8 months out of warranty and had only done 20,000 miles. This is not wear and tear, it's a manufacturing fault which they are fully aware of. A guy at the garage said they've had some cars as low as 5,000 miles fail !!. I had bought the car from the dealer and had it serviced there, so when it failed I spoke to them. At first they offered £500 off, but I couldn't afford 5k for the repair but they must have heard my wife in the background saying she was going to put it on social media as she was absolutely disgusted. They phoned back a few minutes later and offered £1,400 which I accepted. I still feel ripped off at that, we shouldn't be paying for their mistakes in manufacturing. Hope this helps

Thanks for your update, so far They have offered to cover 75% of the cost which I have accepted but it will still set me back around 1500 ish. Currently without a car, could be for weeks depending on how much a courtesy car may be. I do feel like since there are so many issues with this Mercedes should do a recall to check the parts and replace them as good will as opposed to making Customers foot a heavy bill but my local dealership have been fantastic in assisting so I am very pleased with their help

There’s a certain amount of discrimination going on by M-B.
Because USA & Canada are more litigious that say UK/EU, all A220 / A35 owners have an extended 15 year engine warranty provided because of this issue. But not in the UK/EU or Rest of the World.

That’s M-B for you. And no, they are not a ‘premium brand’ per se. They may have some premium cars in their line-up, but they are not a ‘premium brand’. Good marketing and advertising though

Hello guys i'm new to the forum and would like very much if you can give me your opinion. I'm from Brazil, the a35 is not a common car here, but it's a dream. I found one 2020, out of warranty, with 51k km. There's no history of the cylinder head problem beeing fixed under warranty either.

From what I could see when reading the topics, the problem seems to have appeared more frequently before this mileage. Even so, I'm demanding a cylinder compression test before considering the purchase, do you think that this way I am relatively protected from the problem? and whoever had the problem fixed, has there been any case of the problem appearing again or with the new part number there are no reports? Thanks

My car was a 70 plate which is late 2020 and only had 33k miles when the cylinder head issue occurred. Ended up getting it fixed for 1100 gbp after i complained to Mercedes enough to get the initial 5000 gbp quoted reduced. I wouldn't risk it on an A35 after being stung like this without extended warranty and it has actually made hesitant about purchasing Mercedes in the future

Hi all,

Don't suppose anyone would know what / also have dealt with this kind of whistling noise from inside the cabin? It only seems to happen around 30-35Mph and it isn't every time the car is driven. It's just came back from Merc after having it's cylinder head repair and I was hoping everything would be fixed on it but possibly not... I haven't noticed any loss of power and there's no engine lights on (yet) but it doesn't sound like turbo to me so I am slightly concerned after the issues I have had so far that it could be a vacuum leak which would lead to more cylinder head issues

To add to this, there seems to be no difference if AC / heaters are on or off

You could have done a quick search of the forum!

Annoying whistling noise in cabin

Hi, I have an annoying whistling noise on my '19 plate A class (used, but had it less than a week!). It appears to come from one of the front vents, or the vent on the top of the dashboard. Strangely it's only really noticeable at speeds above 60mph and when the blowers are on. It also gets...

Scuttle Panel is firmly in place and is flush with the Glass. Above thread seems to mention speeds over 60 consistently but my issue is only roughly between 30 and 35. Can move this to another thread if there's one better suited, but this only really occurred after the repair so wasn't sure where best to put this
