What could possibly be saved from this one?

[q149]

Saw this nice one pop up today in Belgium: https://www.autojacques.com/schadeauto-schadewagen/car/17234747481409973157/bmw-z4-sdrive23i-2012/

Car seemed in excellent condition until it flooded. About 22000 miles (35000 km) on the clock, seems to be on a Luxemburg plate. Not that I will buy it, but I started wondering what could be reused? Engine with/without revision? Gearbox? All kinds of plastics, tyres, rims,...

Hydraulic pump from the roof will be toast I'm afraid

Everything with a switch, sensor ECU will be toast..a few metal parts and plastics ..about it..

 

[Mr Tidy]

I doubt it would be enough to cover the €5,600 price!

 

[q149]

But what about a flooded engine? The seller states engine ok, transmission ok. At the very least I doubt that the engine would be recoverable, not without a full revision. But I'm not a technician, so what are the experts thinking?

 

[q149]

Exactly what I was thinking

 

[q149]

I was thinking about the gear shift knob and covering, cause mine isn't looking great anymore. Except, mine is an M model and 5600 euro is a bit to much for a gear knob...

That a high water line!!
Bodywork may be OK, if it was fresh water and not salt water. As stated all electrics will be done for, but looking at it it's a very basic version anyway, so it's probably not worth the price, especially considering you can buy some UK cars at that price that are OK!

 

[Marcoose]

Most of the wheel assembly, suspension, transmission, chassis and bodywork should be good. Some of the trim too. They’re all made to sustain rain, water and bad weather in general. And the stubby aerial. A classic never dies.

 

[AnubisZed]

The thing is, the majority on here are from the UK, and thus by UK prices that's probably seen as not worth it. But that Z4 is in Europe, and the prices of cars and parts are higher, especially in certain countries, so for some that would be a decent deal!

Nothing wrong with a little ///M tax. :lol:

 

[Marcoose]

Precious :fuelfire:

Very true, prices throughout Europe are generally the same more or less be it France Germany etc and I know here in Spain that car in good working condition at that mileage would be worth around 25,000€. So for someone in Europe it maybe worth it, but not the case for the UK.

Engine, gearbox and diff not salvageable without full strip down..accessories like injectors, LPFP, alternator, water pump, a/c shot..

gearbox and diff not salvageable without full strip down

I'm not saying they are like new. The only way to really, really know is to strip them down. But unless the seals failed, the internals should've stayed intact. If the marks on the cluster is the water mark, that's not even 1 metre of water, less than 1 atm. And neither the gearbox or diff are assembled in vacuum. The seals should've worked just fine. Many cars, many BMWs have crossed bodies of water that deep and come out in perfect working condition.

Primary issue is corrosion caused by trapped water ..this eats in rapidly to bearing surfaces and hardened gear services etc..you may consider it..I wouldn’t ..

Only if the seals failed. In less than a metre of water, they probably worked.

All the units are vented so water will get in..but as I said feel free..I’d just buy the relevant part from a breaker..or if you shop around for that price you can buy a Zed that hadn’t been flooded

Then every car I've sold was doomed. Because for absolutely sure I've crossed half metre of water with every single one. I've only bought two new cars. I bet most of the used ones also had seen water above the diff line. I suppose I'm lucky.

Transient exposure at 50 cms is one thing..soaking at around a metre for several days /weeks is another
