Scary dashboard warning lights on DB9

[Philip0]

I got my 2007 DB9 back from Works Service today - had a regular service, plus a replacement trasmission oil cooler set and replacement glass PRND swtiches (which I provided).

On its return it had the following warning lights on the dash,,,,







The car runs perfectly well.

Simon at Works Service advised that I take it to a local dealer to have it checked. Local dealer is too busy (to fix someone else's issue?), so;

- are these serious, especially the gearbox message?
- are these fault codes likely to rectify themselves after a few runs?
- can I clear them with a OBD2 reader?
- is there likely to be a fault with the new glass "D" switch? It seems to work OK but I need to press it right in the middle.

All advice or previous experience gratefully received.....

Sometimes they get their knicker in a twist - especially if the gearbox actually works and feel attached to the car! Mine said something silly the other day - 'virtual dipstick glitch' or something - was all fine the next morning Power it down for 20 mins and have another go.

I think I would be on the phone to the service manager at Works and making sure they come and collect it, sort it and then return it FOC pretty pronto.

They should bring you a replacement vehicle to use whilst they are doing so too.

I've had the gearbox warning a couple of times. For me it wasn't anything serious.... Essentially If I don't fully depress the gear switch selector then it gives me this message. Not sure its the same for yours but give it a try.

I had the emissions one too. I took the car for a blast and let the engine rev hard and it went away.

I can get the gearbox fault on demand. If I pull both paddles for neutral then it's fine. If I and press the N then it always says that message (both cases after driving and waiting at lights / in traffic)

I have just had a firmware update so we'll see if it persists. Neither message are fatal but better to get them checked.

Had this on occasion if I try to put into drive or reverse too soon after starting . Possibly a low voltage thing? If I wait a couple of seconds it is fine.

Of note when I had the electric seat recall done they also said they did a software update on the gearbox. (2005 car).

The people on here are right that these error messages are often nothing, however the diagnostics are there for a reason so there is always the chance something went wrong while it was being worked on. Since it's just come back from Works with these errors showing they should absolutely take care of it.

A couple days after my brake pad service warning came on I got the emission service one too. Replaced the brake pads, wear indicators and the emission went away too. I'd think Works would have taken your vehicle for a quick ride after any service. I vote they should fix also.

Thanks, all for your advice - it seems that if the car is started and then the PRND buttons are used quickly and not pressed firmly into centre (so much for a fast get-away?), gearbox and/or emissions fault messages can intermittently appear.

It is now rectified after;

- 3 trips out to get the car fully to operating temperature and then fully cooled down
- Erasing faults with OBD reader
- Putting battery conditioner on so battery is fully charged
- Taking care to press the PRND buttons fully and centrally

Which remedy worked, I'm not sure, but at least I'm reassured that there is no gearbox problem. Thanks again for those who gave useful advice.
