Timing chain OEM Audi or OEM FORD

Mate, this is probably the timing chain and tensioner.

You’ve already got **P0016**, stalling at idle, worse with start stop, and some cold start noise. That’s all early timing issues on these.

I had something similar just done. Started with leaking gaskets so I went on ahead and got the timing chain, cam phasers, water pump...all changed out.

My 4.0 V6 Mustang has not jumped timing and destroyed the engine despite the 4.0 being infamous for it at very low mileage. It's probably because I actually take care of my car and change the oil regularly.

My Q7 with the 3.0 Superchsrged has only adjusted timing due to chain wear by a degree or two from last I checked. 8 degrees is considered immediate chain replacement, and I have 100k miles

Seen a few comments about the 1.0 ecoboost wet belts. The post 2018 focus/fiesta moved to a timing chain on some cars (the only way to conclusively check this is by looking under the bonet)

The 4.0 SOHC timing chain is basically a deathnail to these because it's such a big labor intensive "engine-out" job. That and rust. The rocker panels under the plastic trim, etc. If the 5R55E transmission had problems, it was usually just a valve body problem, and you can buy a rebuilt upgraded valve body for $200. So it was an easy fix. Also a lot of body parts for these have become unobtanium. If you need a fender you'll need to find one at a salvage yard. Mechanically most of the parts were the same as a Ranger, so plenty of parts availability there.

Engine grenaded. Timing chain issue.

I decided against the allroad due to the ea888 engine issues. I can deal with some problems but was not willing to deal with the flawed and fragile timing chain/guide failures along with the low tension piston ring problems. It’s a shame because I love these allroads. I ended up buying a 2020 Volvo xc60 which thus far has been problem free but it’s not a forever vehicle and I’ll probably dump it when it gets close to 100k on the clock. It’s a real shame that Audi doesn’t seem capable of building a solid engine anymore. The Audi timing chain service will set you back $3-$5k and even more if the piston rings get clogged and stuck. Audi has known about both problems for many years and does nothing to improve this engine. Volvo had piston ring issues for a few years but addressed the problem in 2017 and up engines. I prefer a timing belt vs a chain. The Volvo timing belt interval is 150k miles and not terribly expensive. My ea113 VW timing belt is super easy to replace and has a 110,000 mile interval. From an engineering perspective the belt is superior with less weight and more teeth per area. If Audi would put the good old ea113 in an allroad I’d buy it. Keen Audi fans will note that when the tts came out Audi dusted off the ea113 to use in that highly boosted model because they knew it was a much stronger engine.

What I did not know is that the Audi timing chains are *designed* to stretch. Yes you read that right. They stretch. They use both metallic *and* interlocking plastic components and will slowly over time reach a point where your timing is subtly off (and the sensors "designed" to warn you of this do NOT warn you soon enough). This, combined with my wife largely driving it like a grandma, slowly and silently destroyed my catalytic converter required a massive overhaul of both the exhaust system and timing chain, pulleys, etc.

1976 Ford Custom 500, 400 ci, timing chain lifted off the sprockets, 3 cam lobes were rounded. Oil was regularly changed.
