Hi.

I have a 2019 1.5 tsi on 60.500 miles. Its had every service and has always been looked after by the same Skoda/VW dealership.

I have the All In plan and this will expire in Dec.

Approx 2 months ago it developed a sudden onset engine noise. Its a tappety type noise that was most evident under load when pulling away or accelerating hard.

In late April the dealer looked at it and couldnt identify a cause without stripping the head off - I was quoted £1400 for just disassembly. I was informed if it wasnt a warranteeable fault I would be liable for any repair and reassembly costs. As the car drove without any issue it was suggested I took it away and drove to see if it worsened or a major fault occurred.

Fast forward 5 weeks and whilst driving I got an 'oil sensor fault' message and 'engine rpm reduced to 3ooo rpm' and went into limp mode. This was accompanied by a great deal more noise.

I attempted to carefully continue my short drive but the engine water temp went off the scale.

AA recovery under the warranty attended and identified various HISTORIC fault codes including a couple relating to the ACT system. The AA guy reckoned the belt/chain had a issue with either stretching or a guide had failed. The engine noise was massively worse and was audible at all times including tickover.

Its been checked over by the master tech at the dealership who has found the fault codes relate to just a failed fuse. This has been replaced and the car now operates properly.

But still has the noise which the dealership accept is much worse then 5 weeks ago.

They suggest its not as bad as when it was recovered as the oil sensor fuse failure would be responsible for a certain amount of noise.

But what about the 'Historic' fault codes relating to the ACT/camshaft/belt/chain?

My laymans understanding is a historic code is over a week old - so predates the sensor issue as a fuse either works or doesnt?

And an engine at just 60k on an automatic gearbox shouldnt sound like this and not be a warranty issue surely? I cant sell the car in the state and no-one would take it as a part-ex.

Has anyone any helpful suggestions please or similar experiences?

Thanks!

It is a BELT. What has the Servicing actually involved other then Oil & Filter and Pollen Filter. Were the spark plugs replaced at 4 years / 40,000 miles. Has the Air Filter ever been replaced, or looked at? Is the DSG getting a service before 80,000 miles or has it been done already? PS. XXXXXXXXXXXXXXThe Cam belt replacement was @ 5 years / 50,000 milers until 2023 when Skoda changed that. Maybe the Cam Belt and tensioners do need replaced.

Has the engine ever been run with low oil or coolant levels?

Did the sudden onset of the noise coincide with any service work?

Engine noise that you describe cannot be normal - did your Dealership advise against driving the vehicle until the cause of the noise was correctly diagnosed?

Significant increase of noise under acceleration sounds more like bottom end (crank or connecting rods) to me.

Its never been run with low coolant or low anything.

All service items including air filter and spark plugs were replaced 14 months ago at 42k.

Engine oil also changed every 10k

The gearbox oil was changed at 20k and then the mechatronic unit was replaced last july so assuming fluids would be changed again.

All at same dealership and all recorded on service history.

So warranty covering a faulty DSG. Yes oil and filter should be replaced when a MCU is. The Invoices should show they did change the Filter. 20,000 mile oil changed must have been because of reported issues. Really best you get a proper diagnosis while covered by warranty. The Cam Belt can be inspected, That is without a full strip down.
