It would be useful to get a handle on what's going on with the A35 engine and how many are effected and how long MB are taking to get the cars fixed

This is what I have seen on Google AI. But lets not give it further airtime:
- Repair and Recurrence:
While a cylinder head replacement is a common fix, some owners have reported the issue recurring after the repair, suggesting a potential underlying problem or a flaw in the repair process.

😂A generalised response from Google AI about the perils of a repeated fault following a repair, with zero nuance about the specifics of the M260 engine, nor the difference between a repair carried out by a professional or not, whether it was a quality repair, or just a replacement without looking into further contributory factors etc.
Yes. Agreed. Let’s not give this any further airtime!!! 😂
Good luck but note from the experience of others that MB have been contributing to the repair.
Our 2019 A35 with 40k miles, which we have had since new and has had a very easy life last week, started to show an engine light. this was investigated by our local MOT man who was putting a new battery on the car at the time. ‘Cylinder 4’ was what came up on his computer. After putting a new coil on it we noticed the engine had started to feel a little jittery after it warmed up. It then showed an engine light again. (but it was not always staying or coming on constantly) We spoke to an independent MB specialist who advised a valve problem and this could also lead to a cylinder head replacement. He advised us that as the vehicle‘s warranty had expired but it had full MB dealer service history and was relatively low milage to book into a MB dealership and then after repairs plead for a goodwill gesture.
we dropped off the vehicle to my local MB dealership, they quoted £270 to investigate. They then came back with low compression and said that it would be £4,000 to take the head off to make further checks. I asked the MB employee if this was a known fault on the A35 (after i had read up on MB forums that the valves could be faulty on the earlier cars) and also mentioned to him the USA/Canadian MB letter. He said that he was not aware himself as he had not been employed at MB that long. I asked if there was any technicians that could advise me if this was a known problem with these engines but was told the only other person who could have assisted me was on annual leave. I asked to have a think about it before agreeing to pay 4k. When I called MB back to agree to the further investigation work I was informed that he had spoken to a manager who said that MB had previously given a 50% goodwill discount to someone who had the same issue, but could not promise anything until they took the head off to investigate the issue further.
i will update more in the next couple of days.
An update regarding our 2019 A35 AMG.
MB Dealership has confirmed a new cylinder head is required and quoted almost £6,000. Despite the vehicle having full MB service history since new and relatively low mileage, they have only offered a discount of 11%.

Within the dealership I use there is a warranty and claims manager. They contact MB about GW gestures. Either your dealership contact MB or you should for a GW gesture. Your quote in terms of what you will have to pay is too high compared to what others were achieving.
Will check that out, thanks for the advice.
Update regarding Manufacturer contribution for our 2019 A35 AMG:
After initially offering a discount of 11% against a quote of almost £6k to repair the cylinder head, Mercedes have come back via the dealership to offer a 40% goodwill gesture to the repair. Leaving us to pay £3750. As we have only been dealing with a chap from service reception at our local dealer, we will now contact the warranty and claims manager to try to push for more of a contribution from Mercedes.

Thanks for the update. Look forward to hearing if you’ll get any more from them.
We had a rather curt response from the service manager at our dealer who has informed us that the 40% is full and final contribution and that we have to either pay the 60% balance on the invoice or they will put the car back together as it is and then we would have to pay the diagnostic fee of £4500. And if we do not choose either option by the end of today we will also incur storage charges of £50 per day on top.
Shoddy garage behaviour. Contact the MB CEO.
