The Diesel ECU Repairs guide to identifying water damage associated with your vehicle's ECU
Rainy season has arrived and for any vehicle owners who have experienced an ECU malfunction as a result of water ingress, you already know the impact that this kind of electrical damage can cause. Unfortunately there are several models of vehicle that are very susceptible to this type of ingress due to the way the ECUs are positioned.

Common Signs & Vehicle Models
If you happen to be the owner of a Vaxhaul Corsa 1.3 diesel, sorry to say you are particularly prone to a water damaged ECU of this kind. Here at Tamar Electronics, we specialise in diesel engine ECU repairs and the Corsa is one model we see regularly during wet weather periods.
The Corsa however isn’t the only model that finds itself susceptible in this way, as many others also find their way into this category depending on the age of the model. The VW Golf is another such vehicle that can be placed into this “water damaged” category amongst others.
We would always recommend checking your model in our “common problems” page which has been designed to make it easy for you to find your car and check the common ECU faults associated with that model.

Get Your Vehicle Tested
In terms of typical symptoms, there isn’t one but rather a number of possible things. Of course the only way to be sure if to have your vehicle ECU tested (which is actually a much lower cost than taking it to a garage in the first instance).
Here at Tamar Electronics we offer testing services for all DIESEL vehicle models - please note we only service diesel models however and not petrol versions.
So whether you find yourself experiencing intermittent start-stop problems that leaves the mechanic scratching their heads, or if you find that when you push the throttle, you get nothing happening (sometimes accompanied by warning lights on the dash). It could be advisable to rule out the ECU as the cause of the problem before taking your car to a garage and ending up with a hefty bill as a result.
