Car Types
I will be updating sub pages of this topic for more specific help and instructions on different car types. Your comments on different car types are very helpful to other unfortunate drivers, please keep them coming!!!!
Audi;
Audi’s have a fair share of misfuelings, they have some fantastic diesel engines and are becoming very popular, here’s a short piece on how to fix the a misfuelled AUDI.
A3, has the same under bench tank system as a golf, so if you have misfueled an audi, and not driven it, simply yank up the back seat bench – which unclips, and unscrew the tank cover, you can then directly access the tank and drain the fuel from the audi – without having to go to an audi main dealer for wrong fuel removal

Hi,
My mum has accidnetley put petrol in her deiesel 2008 corsa. I’m happy working on cars, but cant find anywhere on line which suggests how to drain the tank.. Any advice would be grateful..
mums eh.. who’d have em?
Corsa, disconeect the feed pipe to the fuel fump and crank the key from o to just before starting position, you should get out a cup full at a time, rinse and repeat and you will empty it, keep in mind the ABC’s A) your battery might start to die so Keep jump leads handy B) when its empty fill it with clean diesel and turn the key 3 more time to clean the pipes C) mum’s come in useful, dont put her in a home just yet, a well domesticated mum can clean, cook, do the washing and attend to a myriad of chores
Hi……my husband (shamed to admit) said he put £10 of petrol into our Audi A3 1.9 TDI Sport and then filled up with Diesel, to make it a full tank. Said it will do it good and clean everything out, as he said he noticed it was not it’s usual zippy self. We then went on a hour journey onto the M62 Westbound and then same journey back, all seems ok. But still sceptical, and both my dad and brother in law said what a load of rubbish it will not do it good….and i am on my own all week it as had some spluttering and yesterday it would not start first time, did on the 2nd? Help any advice? And is it good or bad? He said he does this on his VWT4 van so once a month would not harm it??? HELP!
Thanks
Hi, sounds like you might want to have a fuel drain done on that, some cars are more touchy about it than others, I dont want to say your husband is wrong….. but
Hi great site
Ive put wrong fuel in my Q7 i was told go to a sender unit under seat i cant find it but cant seem to get under seat – car has been sat for 2 days any advice would be grateful as dont want to pay audi prices!
Cheers
Hi Rob, The sender is under the back seat, lift out the seat bench seat – a hard tug will do it
Hi, i have an 05 mazda 6 diesel and i’m not sure if i put petrol in it, i topped up £40 as normal and drove it about 8 miles home, it did feel slightly lumpy at low speed, but when i put my foot down it was ok, nearly home the engine started sounding noisy and when i got back it wouldn,t start straight away and when it did start it ticked over ok, but when i revved the engine it juddered and sounded loud…with a large puff of white smoke, as i say, i dont know if i put petrol in, sounds stupid i know, but i was kinda on auto pilot!!….would these symptons be a fuel mix up????
Hi Jon, yes that sounds like youve put the wrong fuel in, when an engine is already warm it can just about cope – which yours did, but they will not start from cold with the wrong fuel, a fuel drain on that is a straight forward job for a fuel mechanic
Hi have put in 60 pounds pounds of petrol in my Bmw X5 2007 Diesel. tried sucking out some from fuel neck got about 40 liters then stoped, Gauge showing half full, like you said in one of your cars lift up seats in rear and go to sender unit,Yes we find but a silver strap around the unit we cant get to it at all, tried rachet still no joy. Looked around engine cant find fuel line. Any help or information greatly recieved tanx. Called BMW garage Quoting hundreds of pounds, no way. Regards kevin. Any photos to show details would be great. Cheers.
Hi Kevin, no photos of x5 fuel system but if you unbolt the plastic engine cowling you will see the fuel lines,on the tank is the silver strap round? – if it is then needs quite a hefty smack to unscrew, I use a very large screwdriver and a rubber mallet, hit it hard (man hard) and it will untwist, call me on the phone if you run into trouble with it
