Default 407 Coupe Limp Mode

Have a 2006 2.7. Had the cambelt done last week, picked the car up last Thursday and it has been fine until yesterday. It now keeps going into limp mode, sometimes coming up with speed control system fault message but not always. No other fault messages coming up. Have tried disconnecting the battery to reset ECU, car was fine for about 10 minutes and then went into limp mode again.

Any suggestions gratefully received.

Chances are something has been disturbed / damaged / not re-connected properly after the cambelt work.

BSI reset next then diagnostic:

Its in a garage for diagnostic, well see what comes up.

Typically, it drove fine this morning, so only seems to happen when the car is warmed up, so bad connection somewhere seems a good bet.

Garage found a few fault codes which they cleared- p1351, 0408,0403 ( which I expect as EGR are blanked), p0104.

Car drive fine all day until I went out to pick up my girlfriend, the speed control error message came up again and it went into limp mode again, so it’s definately connected to the cruise control.

Cruise control issue will more than likely be a consequence and not a cause .

The air mass code is the important one

Cruise uses engine load signals to operate so if anything goes wrong with these signals cruise often becomes disabled .

How are the egrs blanked off ...are they plated off on the valves themselves ?

You need to look at both air mass signals in live data and log at various engine loads , they should be pretty even between the banks .

If they are not even the trunking from turbos to air mass meters needs to be checked for secure fitting :
If the turbo pipe work is good but the air mass readings are showing a big difference between banks .....next step ......

If the the egrs where plated off could the plates have fell out when any of the pipe work was removed for the cam belt job , one could be plated off and the other one is not

I work on site, drove from Fife to near Chester with no problems the morning, kept the CC turned off.

Will check hoses etc when I get a chance, but this does seem to point to the CC being the cause of the problem?

0% chance of it being the CC.

Try and get it on Peugeot Planet, it will give you an indication of what's going wrong that way. Standard diagnostics are pointless usually.
