- In this video, Mike outlines the bolt on to the engine emissions devices and emissions related diagnostics which can develop problems and trigger the seen all too often and dreaded ‘check engine’, or ‘emissions system failure error’ messages on your Aston Martin V8 and or V12 engined car.
Mike identifies the most failure prone systems as being; Secondary Air injection, Exhaust Gas Recirculation and failures with exhaust gas oxygen sensors.
Mike then goes on to outline how each one of those systems functions, and the reasons behind why they were added to your car.
But more Importantly, Mike outlines a more and better cost effective approach to resolving such issues, rather than just handing over buckets of cash at main agents for components and repairs which aren’t actually needed to make the engine work or to drive the car.
For the Aston Martin V8 Vantage, DB9, Rapide, DBS, V12Vantage, Aston Martin Virage and new Aston Martin Vanquish, Rapide S and V12VS models. If you have an emissions system related engine problem, probably, its the independent networks you need to seek out for them to put the car back on the tarmac at the most cost effective repair price.
After digesting the information in this video, you will be able to make an informed decision which type of maintenance and repair options is the best suited to look after your Aston Martin.

I'm grateful Mike answered the phone when I called him in panic from the dealership, otherwise I could have had an expensive day. My tale of woe: I had previously had the EML/ emissions warning light a few times, read and reset the code and didn’t worry about it. But thought I’d get it checked by the dealer before the warrantee ran out. After a long drive (although not chore in an Aston) and an hour of diagnostics, an air leak was found with the secondary air injection system that the dealer said would likely take another 4 hours of diagnostics to locate (not fix, locate @£240 ph). They couldn’t say whether this would likely be covered by the warrantee or describe what parts it comprised of. Suggestion was then made that I should leave the car as it might not be safe to drive. So lesson learnt about both warrantees and dealerships. Thanks again Mike for taking the time to explain what the secondary air injection system does, and for offering a sensible approach to the problem.👍
That shop rate is not to be taken seriously. I can’t believe they have the nerve to demand that rate, and that people pay it.
@@lebojay It was a shakedown, pure and simple, especially the whole 'car might not be safe to drive' crap 🙂. But if people aren't aware there's an alternative, they have little choice but to pay.
There is just no substitute for good honest genuine advice.
100% respect and trust for Bamford Rose.
Other garages to pay you how to do their jobs , priceless😂, keep up the great work
Excellent description of the secondary air system, I had no idea how limited its use was. (PS can you increase volume of your videos please, they are much quieter than the adverts which blare way too loud after your dulcet tones 😀)
These recent videos from Mike are another level at the moment. Well done.
Car guru and stand up comedian. Excellent video.
I think people like you make Aston Martin cars better than how its now. Thanks for all the videos you post.
Best Vantage video I’ve seen
Thanks Mike for another excellent informative video!
You help keep these cars with people who are passionate about them and not just for those with a lot more money than sense!
Well said and looking forward to my visiit to BR this week
Great video - very funny and informative.
Great video as usual Mike 💥👌
Fantastic. Mike, or anyone for that matter, does anyone know any specialists who might take a similar approach with similar age Ferrari?
Does removing secondary air or egr mean an emissions fail at mot time?
Another GREAT video for important advice....
Having two Maseratis and a Jaguar XJR, I'm constantly thinking of selling one or two and buying an entry level V8 Vantage 4,3 manual.......And as my sister lives in Cornwall(and I live in Finland😂) ...I am very tempted to make the journey and bringing the possible subject to Your care for proper maintenance!
Thanks, Mike... If you had kits for these deleted components and ways to program the ECU for someone in the USA, I would definitely eliminate this on my V8VS.
Great advice 👍 keep the vlogs coming 😊
Informative video, specifically about the secondary air pump.
Regarding the different exhaust system layouts, one question springs to mind, though: The post-2010 4.7 V8 engines no longer had the (external) EGR valve but were instead fitted with a primary cat in the exhaust manifold and a secondary cat further down below - so quite similiar to the V12 layout, it seems. Does that mean that these engines lost the secondary air injection (like the V12)? And does that mean that these engines use an "internal" exhaust gas recirculation by valve overlap instead (like the V12)? If so, why is "cat ingestion" an unknown quantity on the V8 engines? Thanks for an answer.
Brilliant
my question in is how do you program the ecu to not read these items anymore.
i see these issues quite commonly. i fitted a quicksilver headers and hi flow cat to a v8 vantage and no they get cat efficiency codes.
the air injection sucks, it was causing problem in the 90's astons aswell.
I see a cost effective performance improvement by deleting the gas recirculation valve / pipe and an ecu update. Would the difference be noticeable on a v8 vantage?
I didn't realize you played basketball Mike
I like most people who watch your channel know how important stopping misfire damaging the cats is, but I’d like to know what is the actual cause of misfire on the V12.
Plugs and coil packs, especially the two pin coil packs on early DB9s
Makes me wonder what weight savings you could make from these cars…
Over here in the States, you could get away with all of these changes in some States, some of them in some States and none of them in some States. As a general rule the more blue the State is, the less you can get away with. In NH where I live they typically don't inspect every emissions component, just the basic stuff like the cats need to be physically present (or something that looks like them at least) but the OBDII monitors, including the cat efficiency monitor do need to be completed. So a high flow cat is fine as long as the monitor atill passes. Depending on the age of car you can get away with one monitor not completed. If there's more than one monitor not completed you do get a 2 month temp inspection sticker and have to make sure all the monitors have passed in that time. You only get one 60 day temp sticker in a calendar year so if it takes longer then you end up having to drive illegally in order to complete all the monitors. For something like the cat monitor, it would be easy to modify the post O2 sensor to dampen and average the signal good enough to pass the monitor if the cats were missing, but doing that or modifying any emissions related software is illegal, plus any savy Inspector knows what an exhaust with no cats smells like even if the OBDII monitor has been 'persuaded'. I believe messing with the OBDII S/W to change parameters or defeat checks is a Federal crime under the Federal Clean Air Act. Some States have no inspection at all so you will likely get away with anything, some like CA have a full inspection of all components and any modifications have to the CARB certified and they also do a sniff test. Even the cats are different (more $$) in CA, NY, VT and couple more States because the limits are stricter. Even old cars have to have all the original emissions parts present. I have a V8V. but if I had a DB9 I would definitely bend the rules a bit in order to avoid major cat failure. A fine is a lot cheaper than a new engine. But basically in some States your car still has to prove it has everything it came with and can pass a smog test and/or OBDII monitor test and have of course no OBDII DTC's present.
Sounds like you need to move to Texas. You'd be most welcome. 🇨🇱
Politics aside, revenue generated from repair of emissions systems problems seems to be the motivation for testing. Georgia being a prime example.
I think you need a bigger bin !
Are there any equivalent tips specifically for the V12 engines?
Eg can you simply open up the V12 primary cats, remove the ceramic core and then weld the outer shell back up again?
What BR do is remove the manifolds, cut open the cats, extract the ceramic blocks, weld them back together, put flanges in the downpipes (so they’re easier to refit and remove, if I remember rightly), remap the ECU and fit a 3 stage exhaust switch for factory/closed/open. I had my DB9 done, along with their high flow secondary cats and the sound is amazing, along with how much more free revving the engine is. I’ve recently got a bad misfire and I’m so glad that I had the exhaust work done, to prevent engine failure. I drove the car 300 miles round trip to BR for the misfire diagnosis too - which could’ve been catastrophic if the ceramic cats were still present.

They DON'T just cut the cats open and remove the core. Their manifolds are purpose built and use no part of the original manifold. I'm just looking for a cheaper alternative for the short term. My budget doesn't stretch to the car PLUS all the desirable mods. At least not to begin with! I'll have to keep saving up, even after I get the car!! The car is the first step - and then I can gradually modify it to get to my ideal!
You enjoyed doing that far too much.
