Always that moment, at first start after any major engine work. You know you've done it all, there's no reason why it shoudl not start, yet we all have that apprehension. Yet, so rarely does it not work, but we all still worry. Well done, keep up the good work.
It was quite amusing to see the baffled looks of the two in the red Vauxhall next to you at the traffic lights, noticing you alone talking to yourself in the car 😂
Don’t forget the chain tensioners work off primary oil pressure, common problem on these is lazy tensioners leading to excessive early cam wear. I have a full Audi warranty rebuild on my 2015 Allroad at 30000 miles and a snip under £8000.
Dean, 13:25 to 13:29 there are two electric arcs on the module connected by the red wire that comes from the bulkhead (at the top of the screen). Also, it's hard to tell for sure, but the end of the red wire looks burnt. JUST THOUGHT YOU NEED TO KNOW ABOUT THIS...........
That was the power wire from the battery to the engine, I only screwed it on loosely instead of tight which is why you saw it arc. I then tightened it up 😄
@@SavingSalvage Thank God, came here to say the same thing noticed it at 11:17 and thought it was a bad connection on something, hell of an arc, got me worried.😀
I've got the same car same colour same year but the 320 bhp bitdi and I drop the oil every 6k... Well worth the cost of a Mann filter and about 7 litres of oil. I did a wheel bearing last week and broke the ABS sensor and had the same brake servo fault whilst I ordered a new ABS sensor. Love the A7 Tbh.. Mine has done 123k now and I've put 50k on it in just over 2 years.
I have the same bitdi engine and do oil changes every 10k miles and add liqui moly too. Touch wood at 162k miles the turbos and timing chain seem to be OK. 😬😂
Amen chaps change mine every 5k with liqui moly 5w30 molygen. I bought her with 32k and a year and a bit later am on 58k. I could not believe the later oil change intervals on Deans A7? 15 and 20k intervals are Audi having a bloody laugh?
Completely agree with you on long life servicing, i had to rebuild my c5 2.5TDI cams and followers worn out, the claims then were long life servicing to blame. Love the SQ5 i have brought some tickets.
I agree with you on the long life servicing. we have had four 2.0 TDI powered cars and the first thing my mechanic says is get it off long life and do it every 10k. We have never had an engine issue. The A7 is probably my favourite looking Audi and tickets will be bought.
Top work as usual! Just one thing and am sure someone will have noticed there was a spark on top of engine when you cranked the first time and then the second time may be a loose connection probably already sorted now though
Just FYI, you got a thums-up because the Quagmire clip made me laugh. Well done with the repair, glad it's back up and running. Motivation for me to get off my ass and sort mine out lol
Omg.. this job your doing all the time must be hard for regular car service guy, but not for you. You must love this job so much to take projects like that :D. Good job, keep up that positive attitude. World need more people like you. Thank you.
Hello from Ireland again, Dean. Jesus, looks like a massive job, bro. I know nothing about Car engines, Dean. I own a Motorbike Dealership here in Ireland. So all i can do is give you Moral Support, and tell you how Brilliant you are, at what you do. I watch you carefully because you always teach me something new, with every video. I dont bloody know how you can get an engine/gearbox in on your OWN. You're stone mad, Dean. 😂😂😂. Or, an Expert at your job. I think we know which one you are, bro. Im Praying to God himself that this works out, after all the crazy work you're putting into this build. Fantastic job, Dean. Keep up the great work. Lovely Q5. 🙏🙏👌👏👏👏👏👏👏👏👏👏👏👏
VAG Technic in Dudley can code out that low oil pressure for you so that the engine gets proper lubrication across the range - they do have some videos which discuss the issue
10,000 miles is the max for a petrol car, diesels contaminate the oil with carbon from the exhaust, this is abrasive and breaks down the oil fast…. 7,000 miles is the max between oil changes. This one step will extend the life of the entire massive but as most people lease cars and they are in warranty they simply don’t care, its the second owner that foots the bill.
True words, although I have had several company diesel motors, (BMW and Merc), and run them all to 100k plus over 3 years, on 20k intervals, but all motorway miles mainly, with no issues. The lowering of the oil pressure is insane by Audi😡
There is a flash at the back of the engine at first turn over with no fuel (11.20) and again but smaller at first start, maybe a short? Near the red wire
She's beautiful mate 👍🏾 smashed this one out the bag. Quick one Dean don't forget that towing cover on the bumper.. it's been doin my nut in 😂 keep up the good work 👏🏾
Thankfully the code for the servo fault went. Had a similar fault on a 17 plate a4. I believe there is a counter for x amount of brake depresses and the control unit tells you the servo needs replacing. If you send it off to a company such as Ecu testing they can fix it for £300 ish. For future reference.
These engines do not fail because of the 2-stage oil pressure.They fail because of the longlife intervals and driving on low revs all the time, especially while city driving. It is a highway car. I do know cars with those motors which have done 300-400 kkm and they are fine, but it needs a proper 0w30/5w30 oil changed every 10kkm and dynamic style of driving with a mostly highway driving.
Well said - the engine was designed for autobahn barnstorming and if you are not using it that way you've chosen the wrong car (engine). Of course many choose these engines and don't optimise them, hence all the problems.
2 stage oil pressure doesn't help matters - you're right re the longlife oil changes - but as you say yourself they spend a lot of time at low revs - technically in the low pressure oil window. There's also a design issue, also exacerbated by the low oil pressure to do with the variable valve timing gears, which rely on oil lash and at low revs its considered doubtful that they get enough 'quality' lubricant and by the time you factor in the longlife oil 'quality' you'll be looking at a bill somewhere north of £5k for parts alone on a car with as little as 70 or 80k on the clock. - I don't have a Q7 any more....
You need to change the brake servo sensor, failure to do this will result in ABS pump packing in. The cost for this will be in access in £1500 to £3000.
@1m30s thats utter insanity this (apparent) emission reducing stuff all things considered are an absolute net negative in their own right and ONLY a tax on the consumer one way or another inc maintenance/repair costs...
Although without the emission reducing tech you’d be pumping all that out of exhaust. Why should a passer by suck that up? Audi should have done a proper job in the first place
@@alexkemp9001stop buying crap from china, that would stop a lot of pollution from those massive container ship. Stop wars too. Karen's like you Keep blaming motorist.
I was going to suggest that. I have the 272bhp version and it’s in warranty but I am seriously thinking I need to get it done? What is your opinion when it’s in warranty
This year and spec a7 is my absolute dream car, love the looks and everything about it, its phenomenal but this oil pressure issue is definitely concerning, 100k miles and the bottom end is probably close to being gone! Apparently vag came up with a software update for there to raise the pressure but this is rubbish. Me ol 2l tdi volvo v50 is at 250k miles and still runs pornographical, bloody new cars...
When they are new from the factory, there is a setting in Basic Settings for running-in oil pressure that times out after 1000Km (700miles). If you have VCDS or similar, you can turn on the running-in oil pressure every 1000Km for maximum (conventional) oil pressure regime.
If the oil pressure is low by design in ecu, surely that engine failure would be a valid warranty claim no matter how old it is due to it being a issue at point of manufacture
Hi Dean you have done a great job there. On that model is there an engine ecu adaption through odis to up the oil pressure when you have fitted a new engine but using an existing ecu?
@@radovanondrejka3182 it does not have low oil pressure issue if the correct oil is used and replaced every 10kkm. It should be also driven properly, it is a highway not a city car. These motors are capable of making 400-500kkm if drove and maintain according to the rules mentioned above
Im not saying the pressure issue is right but i think its probably the quality of the oil that fucked this engine, the long service intervals. I do mine every 6 k
With what you were saying was the cause to oil starvation, whats changed to stop it happening again with this new engine? Has there been a software update?
More frequent oil.changes won't help with the issues with engines sizing up unfortunately..... only thing is remaping the oil pressure switch over.... which none uk main tuners do .... I did ask many of them and none had a clue about it.....

I learned about the low oil pressure from VAG Tecknic channel. They have a PCM software update that will change the oil pressure at lower rpm.
Great work as always Dean.
You can mapp the oil solenoid out and give it the full pressure on lower rpms!!
I think you have to code the injectors to the ecu aswell if you put ,,new,, injectors to the engine

Re the oil pressure, I wonder does the variable oil pressure compensate for wear in the bearings as the miles clock up.
Great car, respect for going for a new engine
Do you flush the oil feed for the turbos??? And the turbos As doesn't it have the engine oil run in them and will have chunks in as well.

I may of commented before watching the whole thing but can the low oil pressure thing be coded out of the ecu? Sounds like a nightmare to be honest.

Back to watch the last 10 secs as per Instagram lol RS7 ❤️❤️
Whats with the RS7 badge on the front grill? It's really hard to spot as there is a link to another video in the way
So basically sort the oil pressure issue in low rev and change oil every 6k-10k and the 3.0tdi is not a bad buy?
Would it be worth ecu remap to sort the oil pump pressure below 2500 revs?
isn't there a way to deactivate and always set the solenoide in the open position so that you have normal oil pressure and not restricted pressure ?
The sparking at the back of the engine on the red wire!
Yeah didn’t tighten the bolt up, was only on lose.
Did you put the injectors in the Same holes ??.. if not your going to program the injectors to the Ecu to the new cylinders

After the first drive did you have to drain oil for metal shavings? Or do they come pre broken in from Audi?
