oxygen sensors worth of $5600

[Rayray]

Hello everyone

Referring to my last post https://www.pistonheads.com/gassing/topic.asp?t=21...

After putting 98-octane fuel in my car (VIRAGE 2012), the emission faults appeared on my dashboard (P0171 and P0174).

I took the car to the dealership in Riyadh, and they told me the problem was the oxygen sensors.
They quoted me to replace 4 upstream and 4 downstream with a total of ($5600) !!!!!


My genuine question is: should I take the car home, or do I have to change the sensors?

[Simpo Two]

Is 'emission system service required' still coming on? How many miles have you driven since it began?

I'd want a second opinion.

Sounds very like the dealer has taken the fault codes entirely literally, and not actually investigated anything that could cause the faults to appear.

You got an assortment of good advice on the other thread. Even buying your own diagnostic tool is a drop in the ocean vs $5600.

Cheap oxygen sensors are never the way to go, neither is changing all of them because the garage doesn't understand how to perform a proper diagnostic test.

Any decent garage that understands how emission control systems work should have the capability of taking the diagnostic further than the dealer has. If it is an O2 sensor you can tell which one without even lifting the bonnet. Looking at generic OBD data and forcing the engine rich or lean isn't a tricky process.

I drove more than 100 miles on it and no issues.

The dealership is not much reliable. They went far by asking to change all the sensors.

And unfortunately in Riyadh no second opinion on V12 Astons.

They always do. Recklessly ask to change everything and more often they didn't even conduct a full check.

أظنك تتحدث عن حساس واحد، بينما أنا بحاجة لتغيير كل الحساسات الثمانية حسب كلام الوكالة.

Is there an auto diagnostics wizard anywhere? The man who solved my DB9's problem was nothing to do with Aston and didn't have AMDS, but he had brains and could read live data.

All I can add is that I got that emissions warning twice and it went away after about a week, no other noticeable issues.

Just buy the Aston Martin foxwell obd2 scanner and keep deleting the error message then.

Hello

I had two after market o2 sensors in my 4.3 Vantage since 2018 all is well no programming needed at all

Why would you try to argue about this when you clearly have no idea how any of this works?

Lambda sensors mark their own homework. Engine control sensors are not a good place to save money.

It's a good thing that catalysts and engine rebuilds on these are so cheap.
