Help - petrol in a diesel engine!!!!

[Dieselman]

This was all done 4 days ago… yesterday I was driving the car and I noticed that when taking off at the traffic lights…. If I pushed the accelerator slowly the car would just lag and eventually take off just fine.. however if I pushed the accelerator down a little faster the car would start to shake almost like a manual and the engine would stall/cut-off completley

That sounds like the pump may be drawing air in under load. Have the dealer check the pipes they disturbed.

The stuttering, in particular where idling is def a symptom of fuel injector issues, just blast it through. you should be fine by the way. Good luck by the way, and the insurance should be fine as well as you took it a dealer to get fixed right away, any problems since are not your fault. 7k as well seems utterly mental.

oh yeah and even the £650 is very high for what they are doing, I guess you have already paid this.

In the good old days (up to 1980's) we used to put a couple of gallons of petrol into a tank of diesel every time we filled our trucks. I understand how trying to run a diesel on pure petrol could harm but a mixture of the two, especially 10 litres of petrol in say 70 litres of diesel Mix for our trucks was about 10 litres in 350 but this was through the whole winter not just a one off.
Are modern diesels really so sensitive and easily damaged?

If you pop in to Halfords or any car accessories shop, look at the row of fuel cleaners, injector cleaners and the like. Nearly all of them use the same primary ingredient - Diesel. The others use Kerosenes

I once filled a VW Passat 130 Sport PD Diesel with petrol and drove off, didnt get far before I stopped. The AA towed me to a indy garage who disconnected the fuel pipe from the fuel pump to the engine and just run the pump to drain the tank. They then put in a couple of gallons of diesel and told me to fill up at the first garage. They said no problems with petrol in diesel, worst is diesel in petrol.
I put in a full tank of BP Diesel Ultimate and continued to use Ultimate for the next couple of fill ups.
I think the petrol cleaned the diesel system out, the cars performance improved as did the fuel consumption. No new pump, no new filter, no new fuel lines etc and a total bill of approx £280.00+VAT.
Based on my experience with the VW Diesel, I'd say fill it up with a good quality diesel and then give it an Italian Tune Up for a few hundred miles.

The AA have dedicated patrols to deal with mis-fuels. They charge about 250 gbp for non members and 200 for memebers.

Details here.

AA Fuel Assist | Wrong fuel in your car

No idea what they actually do for that fee, but I'd consider paying it if I was stressing tot he degree the OP seems to be.

still ongoing problems

Hi Guys,

So far you's have all been an extremely great help… and I really appreciate all the time you's are all putting in to help me…

This is in relation to my previous post that I made… which can be read at the links below;

HELP ME PLEASE – POURED PETROL IN DIESEL ENGINE… I CANT SLEEP!!!! - MBWorld.org Forums

Okay since then I have taken everyone's advice and replaced the fuel filter with a new one… and this is exactly what the problem is with the car at the moment;

The car starts fine and runs absolutely fine for the first 5min of driving or so.. (basically until the engine warms up I presume)… After this period… when you are at the traffic lights for example… as you begin to take off… if you take your foot off the brake slowly and don't touch the accelerator at all the car seems to take off fine, no problems at all (keep in mind the car is an automatic)…. However, if you take your foot off the brake and hit the accelerator… the car almost comes to a complete stop for a few seconds (as if it was a manual and it was about to stall)… and then takes off again…. Also I have noticed the car is making a strange noise when idling at the lights (but this could be just me..) But the other issue is a definite… because it happened at every set of lights I was at…

Most likely the reason why the dealer couldn't find any faults with the car when they took it for a test drive… was because they didn't take it for a drive long enough… to the period where the engine warmed up and the issues occurred…. (Also keep in mind that the computers have not picked up any faults with the car at all)

I have called a number of different mechanics… and none of them seem to have any clue as to what could be causing this type of issue… I also spoke to a one mechanic who thinks it may be an issue with the injectors… as the injectors provide/spray fuel into the system…. Another said to check to make sure that the cable/connector to the air hose is connected properly…

Would anybody be able to provide me with any assistance…as to what they may think this issue may be… I am taking the car to a specialist diesel mechanic tomorrow to see what he thinks the issue may be (he will undoubtedly charge me an arm and a leg)… I cant believe how much such a small mistake has ended up costing me… £140 pounds for the air filter replacement… towing on multiple occasions… I have already spent approx. £1,300 pounds in total and the car is still not fixed!!! It is a little depressing because it will take me another 3 months worth of working to save up that amount of cash….

So if anybody could please help me… it would be much appreciated…
Thanks heaps guys

(PS. The car has been driven for over 125 miles (200kms) now… so I would have presumed that all of the diesel had been flushed out of the system by now… and the issue would have been resolved… but it doesn't seem to be the case)

This is nothing to do with the mis-fuelling, just take it back tot eh dealer and have them look at it as it wasn't doing it before they worked on it.

As an outside guess I wonder if it could be the EGR valve sticking open. Any black smoke?

Otherwise I'll go back to it possibly being an air leak into the fuel pipes.

Is it the same with the gearbox on both modes (C/S or whatever they're called now)?

Where are you, by the way, your language is a bit mid-Atlantic and you're talking in kms but using £?

Its obviously too late for immediate advise - but as already mentioned on the fourm, when this happens just call AA Fuel Assist. They will come to you day or night, and drain the fuel system, flush it clean and then leave you with £10 of diesel in the tank.

They charge £270 - £320 for the service dependant on your loyalty.

Once that is done (which yours was my Merc by the sound of it) - just fill it up with diesel, 1 can of BG244 cleaner - and take it for a blast on the motorway for a good 100 miles or so.

The BG244 cleans out the Egr valve and injectors etc - its available from ebay, powerenhancer.co.uk and some kwik-fits.

My father in law has put petrol in his C270cdi a few times, twice AA fixed , last time it was just a few litres so he went old school, and filled it with diesel and diluted it through (not recommended).

Last I heard, the AA only had 4 of these dedicated trucks for the whole M25 area so yes they will eventually come but sometimes they may be booked up for a week in advance so you have to wait.

Meanwhile, the petrol in your system is merrily eating into all your seals.

Best advice is to speak to a local garage who can do it much cheaper generally.

If you've not started the car and you are handy with a spanner, go immediately into the petrol station and purchase the appropriate quantity of jerry cans @ £5 each.

Then just pump out your tank by disconnecting the fuel pump outlet hose and apply 12v to your fuel pump, pumping it all out into the jerry cans.

Takes an hour or so and maybe £50 in jerry cans.

HOW MUCH!

We do it for about £100-£150 depending on how much fuel I have to dispose of.

 

[Dieselman]

The downside to using a local garage is you have to get the car to them, which isn't a problem if you have breakdown cover.

Spikes method is good as long as the car has an electric lift pump.
