Discussion
After a bit of advice re: TPMS - I had a puncture in one of the rear tyres of my 2009 DBS that was repairable, however, 24 hours after getting it repaired, I started the car, and got 'Check Tyres' warning on the dash. This persisted through a restart of the engine/system check, but the warning cleared after about 30 minutes of driving.
Any ideas? I'm guessing either a recalibration of the TPMS system is required (Smartire system on pre-2011 AM's don't auto-learn apparently) or could it possibly be down to the pressure in the tyre increasing after it had warmed up, and therefore the warning was cancelled? If the latter was the culprit though, I'd have expected to have had a specific warning for the wheel at fault, not just a general message (does the Smartire system tell you which wheel to check, or is it just a general message to 'check tyres'?)
Any help appreciated!

I did actually have a similar message at another time so I checked all 4 tyres and found that one tyre had lower pressure than the others. There is a possibility that the repaired tyre has not been sufficiently inflated so best check it with your compressor. That resolved my issue.
It could be as simple as that.

I've long given up paying attention to the TPMS, although it's annoying to have it show up.
TPMS reminds me of Mrs Bennet in Pride and Prejudice. "I have a high respect for your nerves. They are my old friends. I have heard you mention them with consideration these twenty years at least."

I had a puncture repaired on my old DB9 at Buckley Tyres without any TPMS issue so I'm not sure why you have one. Did you use a reputable repairer?
There are some on here that would detach their system in a heartbeat
Thanks for the replies chaps! There are some on here that would detach their system in a heartbeat
I got the dealer to repair it, so *should* be able to trust their work! I will be taking it back into them though, but I just wanted to know if this was a known issue.

This is what I'm leaning towards, hence the reason why I'm thinking that the pressure increased as it got warmer, and that resulted in the warning disappearing about 30 minutes into my journey. I'll get them to check the pressure when I take it back into the dealer. It could be as simple as that.

On the AM is the TPMS sensor attached to the valve? Did the fitters remove the valve? Sometimes the valve seat gets a bit corroded and you can lose pressure. Had this very issue sorted out FOC on my Lotus this weekend
In truth, I'm not sure... I wasn't present when the repair was done, but it's entirely possible... V8V Pete said:
My understanding is the sensors have batteries in them that eventually run flat and the sensors need replacing. Had one done on my 2009 V8V this year when changed from winter to summer tyres. No error messages since.
I had all four sensors replaced about six months ago, so I hope it's not anything to do with a battery (not even sure if the Smartire system has batteries to be honest)

If I had my tools here, or there were facilities at the local petrol station, I would have done this myself - I moved out to Dubai last year, and quickly learned that *everything* is done by somebody else! You can't even put fuel in your car yourself!
Apologies, hadn't realised you lived in that giant building site in the desert. Must admit to never looking at petrol stations to see if they have air lines. At least the fuel is cheap!TPMS worked nicely for me on my 2012 (registered) V12V recently. Had a nail in the centre of a tyre. Warning message on dash message centre as I started the car and appropriate lights on TPMS unit above passenger's legs to show there was a problem with one tyre. Blew tyre up enough to drive to nearest repair place without damage and had tyre repaired. Asked man to check pressures on all 4 tyres. All good since. That's the only time I have had a pressure warning. Tyre was saved by the prompt warning.

Yeah, roughly £17 to fill up the tank! Good job, as I'm filling it on a daily basis!OK, so it's definitely looking like it's the pressure in the tyre that was repaired being very slightly below the allowed parameter when cold, as it comes on when the car has been stood overnight or during the day whilst I'm at work, and then goes off within 5-10km of driving, so the pressure is increasing as the tyre warms up.
I'm going to check the TPMS system this evening when I drive home, and I'm expecting the corresponding light to match up with the tyre that was repaired. Out of interest though, I had a look at the TPMS under the dash when I arrived at work this morning (forgot to check when I first set off) and all lights (4x tyre indicators and another light that I'm not sure about) we blinking orange - is this what the SmarTire system does under normal operation, i.e. nothing wrong?

Thanks, that explains a lot! Tyre pressure was 25% below normal in one of the tyres... surprised that warming the tyre up can equal this out though! (unless of course it's an 'up to 25%' low warning light?)See the thread "TPMS Resync" at "6speedonline" forum for the PDF.
