69 Plate in the UK simply means that the car was registered between September 2019 and February 2020. Has nothing to do with when the car was built. If the car was built and took a while to sell, it could easily be registered on a 2020 plate.
Thanks for the response. I've asked the dealer about this and the car I'm looking at had the replacement done. What im wondering now is if anyone knows after the replacement has anyone had any more issues with it, will I have to get them done again down the road or any other issues resulting from this? Ive done some digging around and cant seem to find anything about post replaced cylinder heads. (Also should I steer clear from this vehicle? 2020 Mercedes A35 with 22,0000 Kilometers)

I’m in the same position as a few others on this thread: A35 purchased new August 2019 and only done 8700 miles and so just over 4 months of warranty remaining. I also looked online at: Mercedes-Benz Extended Warranty to see if I could extend the warranty as I don’t want to take the risk of the cylinder head issue after the warranty is up. I entered my reg no and it said that no products were available for me to extend the warranty. I will ring tomorrow and see if I can obtain some assurance that the car will be covered in the event of this happening after warranty expiry, and if I can’t, then I’ll sell the car before it expires.
Crazy cos I love the car but I’m not willing to take the risk.

Thanks @Forrester.

For anyone who’s interested, my quote from MotorEasy was £51.22 pcm minus 10% if bought online today. That was the top product as they do 3 levels of extended warranty from what I could tell.

I also spoke with MB extended warranty today - believe this is sub-contracted out by them - and they said ‘no products available’ result was given because their online system only provides a quote if the car has 90 or less days remaining under warranty.

Anyway, he gave me a quote based on my mileage (8,705) for £323 for one year or £523 for two years. There was also an option to pay £36 per month which would be cancellable at any time. May well take up one of the options closer to the time to relieve the worry of the cylinder head issue possibly looming after the warranty expires. Food for thought.

Very glad to have come across this thread, I'd driven 2.5hrs in my 2019 A35 (25,500mi) up to the lake district for my girlfriend's birthday. About 30mins away from the hotel very similar symptoms to what others have mentioned (flashing engine light, misfires, vibrations, power loss) pulled over in the next town and called the AMG Roadside Assistance, and fair play to them they had a RAC mechanic there in 40mins who diagnosed the issue as a potential cylinder head failure using the logs from the OBD port. Due to it being a 4matic, he was unable to tow it to the nearest dealership, so I had an absolute nightmare over the weekend trying to arrange a replacement hire-car and transporter for the car to be taken to the nearest dealership due to it being a Sunday and in a remote location, I even had to log a complaint with Mercedes as the experience was so bad, over 40 phone calls over the weekend to get people to pull their fingers out and get me home.

I'm waiting on a full report from their initial inspection tomorrow, but reading through this it sounds like it's going to be up there for a couple of weeks. I'm amazed by the number of people that have had the same issue, even "none car people" have commented to me how bad it is for a relatively new car with average mileage for the age. I'm hoping the fix is known internally at Mercedes so it won't be too painful, but I'm not confident.

Also hoping that my Vauxhall Crosslander (whatever that is...) is swapped for something more appropriate if the diagnosis is that it's not going to be a quick turn around, but annoyingly as the dealership is 150mi away from me, I'm not sure how easy it's going to be for them to provide an "appropriate" courtesy car.

Seems the 19 plates are a ticking time bomb, I keep getting paranoid with mine when it does strange things, but I dont think its related to this, it sometimes bounces up and down on the revs going slow in reverse and 1st gear, dont know if this normal but its rare to see. Never had EML on or loss of power mine is a 70 plate, I've heard the part was revised in late 20 plate cars.

Update !!!
After acquiring information and specialist tools needed to remove the cylinder head, I finally found my problem. Removed the head this morning and straight away noticed how wet cylinder 3 was from unburnt fuel. I removed the inlet and exhaust valves on cylinder 3 only expecting to hopefully find a cracked valve. Instead I found that 1 of the exhaust valves was completely burnt out and pitted, therefore couldn’t be seating correctly. Hence my 40% compression loss. Just to double check I reinstalled the exhaust valves and poured fuel into the exhaust manifold to see if the valves would leak, and the valve that was burnt out and pitted leaked fuel everywhere. I couldn’t find any cracks what so ever within the head but I’m sending it away for skimming, pressure testing and valve re-lapping. I’m quite confident that it’s only this 1 valve that has been causing my cylinder 3 miss fire fault. I will update the page when I have the head back and ready for re-installing.

Well done to date. What you are doing is out of most people's league. Did you ask MB about an out of warranty claim initially.

there’s no damage to the valve seat that I can visually see but the pressure test will certainly identify if there is. Also I didn’t bother contacting Mercedes’ again after the trouble I had with them in the first place. They basically refused me as the car isn’t standard because of an aftermarket splitter kit and few other modifications.

Hi Max. Thanks for this thread, and I've made the point in earlier posts. I'm in exactly the same position as you, Sept. 69' plate with mine still under 8k, so feeling exactly the same trepidation on ownership even though I love the car. (and like you, also considered selling before potential issues arise)

Think I will go for the full 2 year deal when I can, so if / when I do eventually part with the car, that's a positive selling point for prospective buyers. As soon as my 90 days are here I will make the call.

If you don't mind, can you tell me which department you spoke to, and what number did you call?

Hi @Craig70, I forgot to ask if the warranty is transferable = I hope it is. I think I will go for the 2 year add on, too. Number I rang was 0345 641 9778. I think the answer machine offered choices and so you just select ‘new business’ or something similar, so no need to ask for department. Didn’t keep me waiting on hold for long. So fairly painless.

Morning @Maxspencer99. Be interesting to see if it is transferable!? Cheers for that, much appreciated (y)

That's balderdash! My warranty runs out in three weeks but I get the same response from that web page.
The costs don't seem too great to extend, though, so I'll phone them and get a quote. I wasn't going to bother until I started reading about these head issues. Perhaps it's a deliberate ploy to get us to fork out for extended warranties!

£523 for a 2 year warranty is very good, and it's certainly not a 'ploy' as the cost to replace the cylinder head issue alone will run in to the thousands, so they will be the losers out of that one.

Pretty sure I'll be taking out the 2 year deal.

''balderdash''......not heard that for years 🤣 🤣

If I were keeping my A35 I would 100% be taking out that extended warranty. What @Leww11 is undertaking is way beyond my capabilities, so I'd need the warranty to pay for someone else to repair my engine if my car were afflicted by this widely reported issue.

Just nice to have the piece of mind that if anything goes wrong with the car, let alone a major engine issue, you're covered.

Normally I don't take out extended warranties on anything, figuring that overall I'll be up even if I have to fork out occasionally. However, the cylinder head issue has worried me somewhat - our car's only done 13K in three years, so I've now broken my rule and taken out the extended warranty! As Craig says, £523 for two years isn't too bad (the one on my other car is £3K for one year!) so it's worth it for peace of mind.
So thanks for the info on this thread - it's been very helpful.

Incidentally, it is transferrable if you sell to a private buyer. If you sell to trade, you can get a pro-rata refund provided you haven't made a claim in that policy year. Both are subject to a £25 admin fee, which is fair enough.

I agree, £523 for an extended 2 year warranty is good value. A no brainer if you are keeping your car longer term.
