well, a letter to the garage concerned, copy trading standards, with a copy of the relevant bit of your credit card statement might elicit some contribution a a gesture to customer service.

Then again, you might just bung in a small claims court claim, I think that's all online now, or go for mediation. You might win, it might cost you fifty quid...

I would do this, It's not for the money in particular but for the sake of others. Someone in the supply chain has been complacent, perhaps a claim may make them sit up and get it right in future. You're just 1 that's been affected, how many other's that you don't know about.

This, and make sure the repairers give you a sample of the fuel just in case it's wanted for analysis.

Unfortunately I would have to take a day off work and hire a van to go down to Dundee and fetch it so as much as I agree with you, that’s not practical.

Then maybe ask bmw to just pump out max of fuel, replace plugs and you take some fuel in jerrycan, bike will be rough first but it will get better, no need 400 for tank remove.

 

[ShakeyGS]

They’ve drained and cleaned the tank and replaced the plugs but still no joy. Next to be checked are the injectors and then after that I guess the fuel pump?

Hope warranty pays now if it is pump.

Except fuel already has alcohol in it, that’s what ethanol is.

And it won’t corrode the injectors, because it’s absorbed by the ethanol,

Petrol contains a large amount of water, that’s where the steam comes from out of the exhaust.

I'm not an expert on the subject. But as fuel is a hydro-carbon the water in the exhaust is a by-product from the combustion.
As for the water in fuel problems, here is an article that may shed a light on the issue:

Water has very little solubility in petrol as the petrol is hydrophobic.
Take a 20lt tank of fuel the actual water content if the petrol is water saturated is around 0.02% or 4mls tops in old money 1/2 teaspoon worth
So any more water that gets in tank will sink to the bottom.
That said a bit of ethanol there will possibly lead to phase separation, which has its own issues in a combustion engine.

As stated earlier when you burn a hydrocarbon in presence of oxygen then yes a by product in the exhaust gas is water of combustion.

Not on a 2016 bike

Luckily, it’s not the pump. It seems that the bike will now run but takes a good few turns to get started. Diagnosis is that the Cam Shaft ignition sensor is faulty.

Copy from google for better explaining.

As the camshaft position sensor weakens, the signal it transmits to the vehicle's ECM also weakens. Eventually, the signal will weaken so much the signal will switch off, and so will the engine. This can happen while the vehicle is parked, or while you are driving. The latter can be a dangerous situation.

Sounds like the fuel fill up was a coincidence. A faulty CPS should put up a fault code.

I’ll be asking why they only just found that…

because the info you gave them led them to assume it was contaminated fuel and they just took the easy way?

Fair comment although I would have thought that with the engine warning light on, the first thing they would do would be to run a diagnostic?

 

[SBD]

You said “BMW have confirmed contamination”.

Was this a case of “yeah, sounds like a dodgy fuel fill, let’s ream the poor f****r for 400 quid” or “we’ve dipped the tank/pulled off a fuel hose and detected an unauthorised mixture of substances in the fuel system and it will take 2.5 hours & new filters to repair”?

Because it sounds like the first one to me, but then again, I might be jumping to conclusions, like the dealer...

I had a Rover Montego years ago, which had a faulty crankshaft sensor. Weirdly it would bump start straight away, but trying to start on the key would just result in cranking. Took ages to diagnose and about 2 minutes to fix.

I think petrol contains no water at all!

No it does not, but when you burn it the chemical reaction creates some H2O as a by-product.

aye, doesn't take long to do diagnostics if the techie knows what he is doing. hope you get it fixed without having to sell bidy parts.
