Hi there,

basically got a tyre pressure warning come on,

checked tyres all were pumped and they were all pretty low

put 2.8 in the front and 3.2 in the rear as I'm always carrying 4 people, this is for the 19" M-Sport Alloys

does that sound right ? the back left was on 29 PSI, not sure what that is in bar, but was way below 3.2 which is what it said on the door panel

is 2.8 front and 3.2 good ? do you think it likey I have a slow puncture ?

do you know anywhere online I can order cheap replacements for RFTs ? I've got Bridgestones on mine RE050 or something . . .

My RFTs seemed to lose air every 2 weeks... once down to 16PSI! in a week!

There was never any damage or hole found etc.. so just keep an eye on it.

Remember to reset the tyre pressure monitor once you have corrected them.

I still get some leakage with my non-RFTs but very little.

yeah bit weird pumped em all back up to standarish pressures and went for a bit of a rag around london, came back and they hadn't budged a bit, will check em all again tomorrow see if there's any change

weird weird weird

One of the sure signs of underinflation is excessive wear at the outside edge of the front tyres. I tend to run my 335D with factory 19" at around mid-way between the normal and fully loaded reccomendations.

I'm having problems with my tyre pressures also.
according the sticker in the car it should run 2,5 bar.
when I checked them, they were all 2,3 bar, but all even.
The system, according to the book checks rolling diameter using the ABS system sensors. It assumes that the tyre pressures are low if the rolling diameter is outside the range, but it does not say what that range should be.
I have reset all tyre pressures to 2,5 bar now, and tried to reset the system as indicated, but it comes back. If I hold te toggle swith down, trying to get the reset word up, it displays a error code "cc-16" or "cc-63"

my vehicle is now only 3 months old. I don't drive it much as it is a second car. It only has 1500 km on it.
I wonder if the car standing for 10 days at a time causes flat spots, and those are detected.
the first time it came up I was driving, and the car already had 1100 km.
until then, I had not seen this symbol.

When the snow has gone, I'll take it back to the dealer, and get him to check those error codes.

I'm not so impressed with the Quality of this car. I've seen many little bugs show up in the short time I've owned it and driven it, but I'll report thos all out in seperate threads to see if any of you have the same issues.
