Over the years on my P38 4.0 V8, 2.5dHSE and recently my L322 4.4 V8 I have suffered power drains.
On the P38s they just flattened the battery.

On the L322 this meant the usual litany of AC, power steering and air suspension faults – as well as flattening the battery. Initially, installing a fresh new battery would cure these issues. Then eventually they came to stay.

Apart from a recent trip to France, when the car performed faultlessly for 5 days, until after a thunderstorm in Dijon, all the the problems returned. I thought about water ingress but a lot of people said this wasn't the case

At my wit's end I decided to sell the car for what I could get.Then a garage I trust suggested I try Cartronics in Byfleet (near the M25 in Surrey). These guys had the car for over a week.

Eventually they found the problem. An ECU underneath the front passenger footwell was sitting in an inch and a half of water. This particular module is impossible to get hold of, so they repaired it put in it a plastic bag and mounted it higher up than before. They also drilled a small hole in the floor to drain any other water.

The bill wasn't small, but the car now runs perfectly. I can't praise Cartronics enough.

Spammer

Not sure I'd recommend an outfit that took a week to find 1 1/2" s of water sloshing about

I wouldn't trust an owner who had his AC on continuously trying to keep his glass clear,

more spanner than spammer.

I hope he informed his insurance company of the structural mod.

Single round through the floor ?

Yes, from below if you live in Ireland.

Always good to keep the aircon on continuously especially in winter even if you don't have water sloshing about, the ECU's do not like humidity.

Hi All,
I concur, air con on, even the wet kids and dog are enough to throw my electrics off line. I have three dehumidifiers in my SC and have to dry out every two weeks. I'll be looking at the said location for water now we have hit the rainy season. Cheers.
Tricky.

As much as I bow to anybody that can get into a box of trickery and fix it.
Not sure drilling a hole is the final fix more a band aid. And surely it can now come up into the hole now.
I would be more interested in knowing where did the water come from in the first place.

As I do,

but sounds like this one needed a lifeguard.
