hi guys had almost a year free trouble driving with my leon cupra r on a 04 plate but yesterday i was driving on the motorway when i lost power and the engine warning light came on (static orange )i pulled onto the hard shoulder and phoned rac . it turned out to be number three coil pack the rac fitted new coil pack (not vag ) and everything seemed to be fine engine warning light was out car was running fine but his diagnostics computer was still showing a fault which read cylinder c secondary circuit malfunction pending. we got home with no trouble but this morning i started the car and engine warning light was back on but with no difference to performance etc

im wondering if anyone might know what the fault could be and do you think the car is ok to drive until i find out the problem as the car drives fine ?

thanks in advance

just been looking at the coils and the clips for holding the connectors for the wiring are broken so someone has been in at them before i bought it . anyway i was wondering if i could change the wiring harness ? i done this with my 200sx as it was faulty was just a case of unplugging it and plugging in the new one and if the harness id faulty could this be the fault the rac were coming up with ? (cylinder c secondary circuit malfunction pending.)

thanks

Id disconnect the battery for 10mins (you need the radio code) which will reset the ecu. Then see if the fault returns.

With the CP not being VAG could it be this causing a fault light?

Find someone local with vagcom and get it scanned if the fault returns.

Mine also has a few splits in the wiring insulation but has never caused running problems

thanks mate will have a look and see if i have the code for radio (i couldnt live with out it lol) and disconnect the battery and she what happens

i have put a post up to see if anyone has got vagcom in the durham area but not got a replay yet

think ill buy a second had vag coil to see if that sorts the problem and if so ill bite the bullet and get four new ones

thanks
