Hi folk,

 

looking for advice for my 2012 vRS Tdi octavia. After 500 miles motorway journey to Manchester I have experienced multiple times engine power loss lasting around 1 to 2 seconds with glow plug and DPF dash lights and on other occasion tyre pressure monitor warning and traction control off signs along with RPM needle dropping to 0. Couple of days after that car would not start at all.

 

All fuses and relays checked and in good working condition.

 

Another issue is with connecting any diagnostic device giving Linkage Error messages. Even with battery disconnection and reconnection same fault message appears.

 

Thanks

i had this issue last year, things i checked, instrument cluster, fuses, ecu, changed battery, it turned out to be the canbus module, (it had water in module) mine would start then cut out,

yours seems to not start at all, sorry i cant help any further,

 

Thank you 111zah111 for reply.

 

I have also noticed that that some of the fuses in E-box in engine bay have no power while ignition is on.

Check your battery ground lead and starter motor connections.

Update:

 

After couple of weeks trying to figure out what is happening I have decided to get in touch with local car electrician. On his arrival he found broken wire from engine bay fuse box that leads to ECU.

 

Broken wire was caused by battery tray chafing on the wire loom.

Thanks for letting us know.

Unfortunately, ECU had to be replaced as well as. With new ECU car is in working order again.
