If you look through my past posts you will see that I have had problems with limp mode before. Had EGR Valve changed in Mar this year then IPS motor. All has been well until last week. Car went into limp mode 3 times in one day. Took it to indie who found following faults, EGR Valve IPS Motor and a sensor that I cant remember. He did say that it could be clogged up again as I spend a lot of time in London and it had’nt had a blast for a few weeks. Booked it in for service as due in 1800 miles anyway. Decided to keep it in S mode instead of C. Following day put it into C got the hump with the sport suspension setting. Turned car off for 15 mins got back in it and straight into limp mode. Turned off an on again all well so left in S mode. Had it serviced yesterday including air filters as clogged again, they never last for 2 services and fuel filter. Car fine last night when I picked it up fast and responsive. This morning all well when started it. Stopped after 15 mins to put a letter in post box, did’nt turn it off but when I got back in it got the distinctive clonk when put into drive that means it in limp mode again. Had just put back into c mode prior to stopping. Turned off and on all well again. Stopped car after 10 mins and started all well still. The next start it was in limp mode but engine light on now!!!. Took it back to be plugged in and this time EGR Valve air mass to low. Cleared fault and he said it could be one of the MAF’s but as they about £300 not sure what route to go down. Car alright this afternoon right up until I put it into C mode, 20 secs later limp mode again. Is this a coincidence or is moving it from s to c mode causing the problem. Any thought welcome.
