Well not had her long and I haven't managed to get to the bottom of a very annoying hesitation, had various codes thrown up along the way, but the main one the comes back is the 17912.
She has a terrible hesitation at low revs turning into junctions roundabouts etc, but once a little up the revs is fine, there is also a louder intake type noise coming from the offside front.
When I first got it 14th February it had three codes logged
17912 - intake air system leak
18322 - fixed brake light switch
17413 - torque difference cylinder 2, limit value exceeded
I cleared these and one week later I had
17912 - intake air system leak
16955 -
16395 -
It was then serviced and we found a damaged intake pipe underneath and the EGR pipe had a split in it, these were all fixed
Then on the 24th March I had
17912 - intake air system leak
17413 - torque difference cylinder 2, limit value exceeded
16804 - catalyst bank 1, efficiency below threshold
Clearded these and have been using it a bit and then on the 31st March I got
16804 - catalyst bank 1, efficiency below threshold
Since then it has not thrown any codes up, still always drives the same with the hesitation.
I then noticed that there was damage to the wiring on the third coil pack not a lot but it could have shorted I guess or got the hump if it got wet?
Today I insulated each one separately and replaced that coil as I had a new one and figure it may have got damaged?
I have cleaned up the earth points on the top of the engine and behind the headlight and I read this on another thread.
I then found that the piece where the oil filler cap goes in seemed loose and when the engine was running I could hear it taking in air and causing idle to hunt a little if I moved it, there is also small traces of oil under it, could this be part of my problem? Would this move under normal driving conditions?
Does seem odd and how do I fix it?
I have tried searching for similar problems before posting but I am now stuck and wish it was fixed as we love this car but this problem is really trying our patience and my wife doesn't like driving it like this.
Cheers in advance
