Hi all!
Unfortunately, I have been having an Immobiliser issue with my Seat Leon Cupra 1.8T 52' (around 95,000 miles on the clock)
The car will not start, it sparks, boots up then shuts down after a second. This is due to the orange immobiliser light coming on and blocking the ECU, resulting in the car not being able to start.
Things I have tried are as follows...
- Checking any broken connections on the Gauge Cluster (all connectors flowing and soldering in reasonable form)
- Had a specialist come to program a new key - could not be programmed and was attempted with several different laptops, therefore seems the issue is with the car rather than the key transponder (I have a key-cover which gives me this service for free!)
From reading previous threads, the above attempts to resolve this issue seem to cross off some common causes of the fault. It is worth noting that the car has had some damp in it as the car got flooded whilst I went on holiday. The seals have been replaced and the car has been dehumidified, however it is looking like an electrical fault has developed since. However, there has not been any other noticeable electrical faults/glitches.
At the moment I am in a position where I do not know where the electrical fault will lie, either on the ECU side, Immobiliser side or somewhere in between! Professional investigation on VAG electrical faults can be very pricey in London and will not always guarantee a fix. The car is mechanically sound and I would love to get her back up and running again!
Also, I wouldn't mind getting some thoughts on disconnecting the immobiliser to get her up and running (until I can find a sustainable fix!) - or whether this would even get the car running! Leaving the car on for a few minutes and disconnecting/reconnecting the battery will get her started up but is far from an actual fix, therefore can be excluded from this thread
Cheers in advance for any advice!
