Firstly, I would like to say hi to all that may take sum kind of interest in my problem.
My name is Jon and ive owned this cdti for 10 months now and still haven't managed to solve error p2279 (air intake leak)
Work so far: tested by my self and at vaux main dealer
All boost pipes including intercooler.
All vac pipes.
Wiring loom tested according to main steeler.
Pre cat cleaned out.
New egr valve replaced and software updated.
New Map sensor.
New Maf sensor.
New Inlet manifold and actuator.
New Boost control valve fitted.
New Glo plugs.
Symptoms: Car starts fine ticks over very nicely... When it reaches 85 deg (temp) it shows P2279 intermittently.. could be 5 mins or fifteen mins into journey. Always accurs when leaving a motorway and then braking.
From what i gather there is a ambiant air sensor on the ECU that can very rarely go wrong as its a Bosh. But im starting to think thats mines gone dodgy and needs replacing.
Has anybody thats owned a cdti experienced similar proplems to mine (only post I found almost identical to this was a Polish guy and after translating he still didn't find a fix but had not changed his ECU)
Ive spoken to a firm in Nottingham for a replacement ECU tech 2 removed and my mainsteeler about a new key and chip ready for programming. roughly £450 all in.
If there is anyone thats got the same problem then this post may help as i will not give in untill ive fixed it
