Diesel Contamination

I fill up at my tesco garage every 2 weeks. Last time I filled up was on Sunday. I have since driving 200-300 miles since then. Anyway last night I drove for about 20 seconds turned round the corner and my car went dead. I thought maybe I never had enough power to keep it going in 3rd. Anyway I tryed to start the car and it wont start. Error message coming up saying engine fault contact workshop. And the orange rope on the dash is flashing yellow.

Got the car into SEAT today. They 1st came to say it was a dodgy wire. After a bit they came out with some diesel in a glass and are stating its been contaminated. I know that I have not put any petrol in there. They aint quite saying its petrol but it has been contaminated.

Then they bought out another glass of someone elses diesel. The other one did smell stronger and was a little bit clearer but nothing else.

Anyway they are going to flush the diesel out my car and put new diesel in there. And if the car starts then they are going to put it down to this. They said it wont be covered by the warranty if this is the case.

Feel like I been robbed if this is the case how can my diesel be contaminated. They said I would have to take it up with TESCO who I fill up with every 2 weeks.

I just hope it does not come down to that and its something else.

What do you guys think anyone had any problems with this error on the dash or with contaminated diesel?

Where do you fill up usually?

I remember a big hoohar about Tesco diesel last year.
#3
Tesco it is, I always fill up there.
#4
Sounds feasible to me that the tanks in the ground have become contaminated, which in turn has lead to your problem. If Seat say that this is the issue, then they are right about taking it up with Tesco but you'll need a report from Seat claiming contaminated diesel.

Fill up elsewhere. I only use Shell, ASDA and Sainsburys. Mainly shell because its near home. :thumbsup:

Have filled up once and it before that warning.
#6
Yeah ill get a report from SEAT. They also holding back some of the diesel incase it is for me to take to Tesco.

I never knew this could happen with putting the right fuel in the car can still contaminate it.

Looks like from now on will have to use somone else.

Whats morrisons like?

Couldn't tell you, but would use a non-supermarket supplier if you top up all the time. As they make money on there fuel supermarkets don't so they buy it off other suppliers. Seems to happen a lot.:thumbsup:

ahh right. any incentive schemes these non supermarkets have? Tesco have clubcard points.

Yeh i suppose.

Shell do points also for example.

so you filled your car up with diesel; drove 200-300 miles on it then it packed in...mechanics check and there is diesel in your tank

somnething is missing in these chain of events

True but i'm sure it can happen with a chemical build up in the diesel pump? Could be wrong though guessing.
#12
The problem you'll have is proving that they supplied contaminated fuel. It's fine to say that you only ever fill up at Tesco, but no court is ever going to believe you without proof.
Get a sample of diesel from the tank, contact Tesco and ask them to investigate, they may tell you to sod off, but they may investigate. Have a word with trading standards officers and give them a sample of the fuel, they may take up the case and check Tescos tanks. Much as I'm sure that you think you're right the outcome may not be too good, the obvious question is how come you managed 200-300 miles before the contamination took effect. Find out from SEAT what the actual engine fault was, you wouldn't get an alarm with contaminated fuel it had to have been something else. This may indicate whether the contaminated fuel caused the fault or not, for example a dodgy cam sensor would not be affected by bad fuel but an oxygen sensor probably would.

Good luck.

did you annoy a child? they may have wee'd in your diesel
#14
its happend before with tesco getting pumps mixed up cars only managing to go 50 yards b4 conking out and they paid out all repairs and compo to all affected but in your case you seem to be the only 1 affected so youl probably stuggle to prove anything
#15
In future, dont goto a dealer, plug your car into Vag Com !!!
#16
So now Seat service technicians have chemist/chemical engineering degrees and doctorates and have analysis equipment built into their eyes and nose? Amazing how far we have come.

Good point. I missed that. I thought he drove 20 secs after filling. Most likely someone has emtied water or something into your tank to nark you.

Just rang them and they cant give me a progress report as the technian has gone home and they cant find the reports. Gotta wait all over the weekend now as a tehnican wont be in till monday. Monday they will give me a call. More stressing and waiting.
#21
Well is diesel suppose to be clear?

They shown me my sample and another sample.

Never know what they do behind close doors.

I would have thought that if it was something to with the fuel at Tesco, then you would have had people in this thread saying "Yeah, that happened to me this week too" by now.


I hope this is the case so it would help us all out.

Won't be recorded if he fills up at Asda in between.:o

I filled the tank fully cost me near £55 and got 200 miles before it went dead. Am no buisness miler. Only got 19k miles on it since december 2006
#29
Chances are the whole tanker was contaminated.

Hope you get your car sorted soon mate.
#30
there is no way you would have been able to do that amount of mileage if your Tesco petrol was contamintated sounds to me like someone has it in for you or it was something else wrong and your garage is pulling a fast one

Got to agree, if the fuel was contaminated at source you would not have gone far...

You really have to some digging here and find out (Ask people that work at Tesco, Pump etc) if anyone else had a problem

A problem like this if widespread is not easily kept quiet....

Thats your best bet, meanwhile expect the bill, get it paid and see how next week goes...

If it happens again, you know you have another problem, also keep to Shell or Esso for the next couple of fill ups....

Thats what I thought I could not go 200 miles otor so from sunday afternoon to thursday night if the tank was contaminated.

The SEAT garage have not said its deffo this, but they are going to flush all the diesel out put new diesel in and see if it starts. If it does they are going to put it down to this. IF not then its something else not to do with it.

Thing is they was showing me my diesel and then another sample did look slightly different but not that noticeable. I never seen them take the diesel out my actual car they just came back with a glass of mine and glass of another and said look at this.

I hope its not a big problem they are trying to get out of in the warranty and trying to get me under osmething ill have to pay for.

What happens under warranty I know it cost me nothing but does the dealer get the costs back from SEAT themselves.

What do you mean someone has got it in for me? What could they have done?

Yes but unless the tank was empty the contaminated fuel would have blended in with good fuel still in the vehicle thefore taking time to cause running issues.
#35
I mostly run the car down to the light comes on. Just stressing me out now. £12k car and dont know whats wrong with it.

Shell do points also for example.


Shell do points, but not as good as clubcard

BP do nectar - again not as good as clubcard

Morrisons you get points and once you have enough you get a £5 voucher

Asda do nothing

Someone who actually knows stuff will pick up on this properly I'm sure, but isn't it the case that you're not supposed to run the fuel down to zero? It's meant to be bad for the engine, I've heard.
#38
I dont always let it run to the limit, I normally fill up before or when the light comes on
#39

I think what happens there is, any gunk ( Technical term ) that is in the fuel tank would get disturbed more as the level falls and would then get sucked into the filter and start clogging it up.
I don't know if that is an old wives tale but it sounds feasible to me.


That would fit with contaminants clogging the engine and causing this breakdown, wouldn't it?
#40
Yeah just have no idea of whats going on till monday then ill know for sure whats gone on.

Ill update on here as soon as I know.
