I once had a boat mis-fuelled with petrol (Volvo turbo-diesel) - ended up with estimated 40/60 mix! - engine ran slightly hot at full throttle, but only discovered mis-fuel, after several hours running, when I checked the tank. Fortunately, resulted in no discernible damage to the engine.

Unlikely to be the immobiliser - fault is more likely to be a faulty connection on the key switch. AFAIK, engine will crank (but not fire) if immobiliser chip incorrect or faulty.

Hello, welcome to the forum. Can you confirm whether the engine cranks-over on the starter motor when you turn the key?

Flash point of Diesel can be even lower if contaminated with other fuels - I recall seeing tests where flash point was found to be down to near room temperatures!

Does the aftermarket HUD on the dash work well?

Hello Nik, I can see no reason why it should - AFAIK, all it does is make the throttle response match the actual pedal position. Mashing the loud pedal to the floor from a standing start probably will.

Were the Police notified? They could prove whether or not she was on the phone.

Hello, welcome to the forum. It sounds as if it is attempting to do a DPF regen.

No, from what I've read in other sections of this forum, an issue can arise if the tensioner is past its best, and the vehicle is allowed to roll backwards with engine stopped and in gear. Apparently this can result in the chain jumping teeth on the chain sprocket.

If they're not prepared to cover excessive oil use, you should still be protected under consumer law - nice-looking car but if the warranty they are offering is as bad as you say, I'd recommend walking (or running) away.

Hi welcome to the forum, if you do go ahead with purchase, strongly advise taking it on an extended road trip, while under warranty, to check for excessive oil use. Insist on rejection for this reason being part of any warranty offered. I'd be interested in hearing of their reaction. Does the service history give any information regarding cam chain and tensioner replacement?

I'm assuming that because you have an EFB battery fitted, you do have automatic stop-start - is that the case? I would consider that battery to be in good condition. It probably could benefit from a recharge, but if it is 9 years old, it's doing really well. There is usually a date stamp on the top of one of the battery terminals (MMYY)

Hello, I would say that this will not be an issue, as you say, the oil will drain back from the tensioner while the engine is stopped. Just refill and restart as normal with one proviso - don't ever permit the engine to turn over in reverse direction while the cam chain tensioner is unpressurised.

@Rock_BatistaIf you would like to monitor battery condition, you could buy a hand-held battery tester - not as convenient as a button press on the dash - but guaranteed to be more accurate. Just need to be aware of the designed undercharging if you have automatic idle stop-start/smart alternator.

There is a test for octane rating - it uses a test engine and compares against 2,2,4 -Trimethylpentane and normal Heptane. You can buy a lab machine (for US$ 2000 😬) which, it is claimed, can give reasonably accurate results. Cheaper to buy a tank of 99 and check the knock sensor.

Hello, welcome to the forum. You say 'a red warning light' - which warning light was it? Oil warning?

Is it just me - or has there been a huge increase in people who think they are entitled to do whatever they like, too bad for anyone else who just wants to get on with their day?

There are suppliers who can supply a replacement key at less than 1/2 the dealer price - some branches of Timpsons (other suppliers available) for instance.

Get fluid tested if it hasn't been changed since new, replace if required. Check servo operation, bleed brakes, consider new pads if badly worn. All a lot cheaper than going up in size.

Topped up twice? - say 0.5 litre each top up, therefore 1.0 litres of oil used in 1500 miles. IIRC, VAG would try to claim that's 'within normal use' figures and refuse to fix anything under warranty 😒

Hello Alfie, welcome to the forum. How many miles have you run since you last topped up the oil? What is your engine code? (3 or 4 letters before engine number on the registration document) Excessive oil use is unfortunately well documented on the 1.8 TSI engine. Not sure why you are not seeing smoke from the exhaust - but I suspect that's where the oil is going. Do a search on this forum using your engine code.

It is possible that you will require a replacement key fob, it sounds as if your remote control function has failed. The immobiliser chip is separate from the remote control buttons and is passive (not battery powered). I believe it is possible, but a bit fiddly, to swap over the immobiliser chip into a new remote control fob.

We got SWMBOs Fabia from there, we were impressed with their sales team.

Good afternoon @ro0ter I would think that you are fully entitled to receive any information from your cars system - plus any supporting data regarding this 'event' that the dealer responsible has in their possession. This sort of ECU failure clearly is not normal for the many battery replacements being carried out - often by the owners themselves. I am more that a little concerned by your reference to the use by the dealer of a battery support 'charging robot' during this battery replacement - this was not necessary, and I wonder if they managed to reverse the connections at some point? In any case, I would maintain that their actions have resulted in serious damage to a vehicle that was operating correctly before delivery to them. If they refuse to accept this, I would suggest engaging legal assistance.

Agree, often find that bargain no brand button cells can be a waste of money. Duracell works for me - but have occasionally had relatively short life from some of them. A good idea to try and rotate use between keys too.
