V8V service - Emission Service Fault

[Graze01]

2007 V8VM 13,000 faultless km so far since July 16 (now at 43,000km)

had the car serviced today, all good, Sunshine Aston did a great job, good communication, loan car, drained catch can, used my oil, filters pads etc. Even the price was great (about 600GBP)

drove it home 80km - perfect

pulled into driveway & it stalled - said limp mode and showed attached


what does this signify (apart from the dealer may have done something wrong?)

Ive emailed the dealer & am sure they will respond just wanted to know likely cause - any advice welcome

car under extended warranty

Thats normally an O2 sensor playing up. Its ok to drive the car, as you can clear the actual message from the screen. However, it will continue to display the same message everytime you start the car.

To clear the message completely, you will need a On-Board Diagnostics, or OBD reader, quite cheap and easy to use (Amazon etc).

Buy one of those, use it clear the message and see if it reappears. If it does and its regular, you'll need one of your O2 sensors replaced. (If your car is under warranty/extended warranty it is covered)

Also make a note of the reader display, as you will then see, if it reappears, if it is the same problem.

This is a regular item on here with this message, it is nothing drastic, it sometimes appears if you haven't driven the car for a while.

I have this at the moment, and reader confirmed 02 sensors.... You can clear the warning triangle and message by pressing the 'read' button each time after you've started the car , which gives you back the digital speedo read out.... The engine warning light will remain on though.....

You can by a code reader from eBay for a tenner that will tell you what the codes are and clear them. I get them about once every few months typically relating to O2 sensors which I will have changed at some point

[telum01]

Almost impossible to know what caused that without using a code reader to start the diagnosis. There are so many things that can cause the emissions warning that you'll need to get the P codes just to start off. I use an Autel MD802, which works pretty well.

will wait for dealer to respond then sort it out

I reset mine using a cheapo reader but it keeps coming back code is P0410 secondary air system ... any ideas guys?

I thought it was the o2 sensors but that code is normally P0133

Sounds like Secondary Air Pump (obvious I know)....it pumps air into the exhaust gases to "clean" them up. It has a fuse so check that (i think it is F14 or F18 in the engine bay but cant see that in the handbook) and it has little valves that can fail if they get too moist. I have a friend in Florida (wet like Lancashire) who this happened too, he just took it off the car cleaned it put it back and all was ok and still is.....

[morty1961]

cheers mate, is the engine bay fuse box diagram and fuse listing shown in the maintenance section of the cars handbook?

[morty1961]

Fuses ok so guess its something a little more sinister

It will most likely clear itself after a few days." They all do that sir..."

[bogie]

Clear the code with OBD II reader and it may or may not come back. If you get the same code up every few weeks/months then investigate further. You can download the codes online in pdf from Aston tech info

There is a relay in the engine bay mounted on a bracket on drivers side inner wing area. Worth checking that is working. If you search hard on the web I found a circuit diag and Aston fault inding sequence for secondary blower motor. I discounted everything but the blower motor then took it into dealer. It was indeed a faulty pump which lives under intake manifold plenum.

Check fuses supplies etc.
