I dont think any 1.6d was ever "born" with this gasket.When did they add in this new gasket? My car is a 67 plate, but comes under as 2018
They changed over to a 3 pot 1.5d for the 2020 onward astra, and i dont think there were any mention of this gasket before 2020.
They had this campaign, where if a costumer complained about chain rattle, they could fit this gasket to mitigate the problem, but that was only in 2021, until december 31, 2021.
Your 2018 is definitively not factory fitted with the gasket as far as i know, in 2018 they were still holding on to their "It's not a fault, it's an engine characteristic"
You know, this was back in the days where people would have been able to claim warranty repair on the engines if they admitted they were faulty or had subpar components and they had just been forced to dump a shit-ton of money into all of these diesel's to fix the clutch/brake problem.
The gasket and repair procedure only came out when warranties had run out.
Total coinsidense offcourse.
They were able to do the full chain/guide/tensioner/gasket repair on Stellantis bill, but this was reserved for people that :
1. Were long time loyal costumers
2. Had every stamp in the book, and only from vauxhall workshops
3. People they deemed likely to buy a vauxhall next time as well.
Even if you had every stamp in the book, and bill's that said that the right oil was changed, and at the right intervals, they would refuse you, this was pure damage control, for people deemed good, return costumers.
The "We will add the tensioner gasket for free" atleast here, looked more like a money-grab as you had to sign a deal, that said that they would disassemble the engine to fit the gasket and possibly replace the tensioner, but that if they found further damage to the chain guides, you would have to either.
1. Pay the price of taking the car further apart, to get to the chain guides, and so on to replace them. (Estimated price £2000+)
2. Pay the price of fitting the tensioner yourself.
So if THEY deemed it needed further repair, the "For free" part totally vanished.
To be honest, i did not trust vauxhall enough to essentially hand over my credit card, and let their moral and ethics, dictate how much money they would take from me.
