I have trawled and trawled the internet with no definative answers.
I have had my seat leon 2008 mk2 for 7 years and have come across several electrical gremlins in that time.
The car was originally purchased with a battery drain - which was found to be the fuse for the 'telephone'
Since then we have had several issues with door lock modules giving up
Headlight faults even though the headlights work when switched on - but they do flicker on start up along with the reverse light and reg lights.
There has been an ignition fault on vcds for some time codes 00576/00884/00883/01744/00885 - dispite these codes the car runs fine for the majority.
Most recently we are having a slugish start issue that we cannot get to the bottom of - originally torsion was out which has now been corrected to 0.74° - if the exhaust cam is adjusted minutely the car will star very quickly but we loose ALL performance and finding the balance between starting and performance doesnt seem possible. Injectors have been replaced along with seals but no significant differance. Maybe in tank lift pump at fault also?!
The straw on the camels back has been the reverse light giving up but not identifying on the dash untill after a full day of trying to trace the wires and fault. We have lead this back to the BCM as the light board works and all wiring has a good level of continuity however we have 0.1v directly from the BCM.
Due to this accumulation of faults im now considering whether there could be a weakness within the BCM but whats the best way to know for sure?
Also if it is the BCM is it as straight forward as having someone mimic/code the second unit with my cars data?
Thank you for an help!
