Hello..

Seriously gutted at the time of writing this.

I have a 2004 307 XSI HDI SW with 85000 miles.

Will start with some background info as to when some issues started.

I filled up with some Tesco Fuel the other day when travelling back from Buxton. While on the motorway the Anti-pollution message came on. Before it came on the car was doing a similar hesitation to when the EGR is playing up.

As soon as the Anti-pollution message came up the hesitation went away. The car was not going into limp mode. Everything wass working great and revving as it should?

The Weird thing is that the car was driving better after the fault came on.

I lashed some Millers Ecomax additive in and it cleared it for a bit and then the AP fault came on again. It finally went off yesterday after filling with with some Nitro+

Drove it last night 120 miles round trip with no problems what so ever. No hesitation, No smoke, Everything fine. MPG was 62 for the journey.

This morning I took the kids to school. Car started and ran perfect.

THEN!! Taking the car for its MOT an hour later after taking the kids to school driving along at 30 mph, the car just lost power. Wouldn't rev, HUGE amounts of white smoke. Some tapping from the engine and then stalled. The anti pollution fault came on the dash..

Now it does not turn over. :nono:

First thing I thought was the cam-belt had gone. Took off cover and checked the belt and its fine so its deffo not that.

The weird thing is that when it happened I turned off the ignition as soon as I noticed the weird noise and smoke but the engine kept on running on its own for about 15 seconds?

Any ideas?

Cheers.

E2a: It happened right outside a recomended independent Pug specialist and they took it back to their garage so hopefully I'll have an idea what it could be.

Did you not get a diagnostic done after the pollution message came up?
If you ran the car with a blocked DPF it can cause a huge amount of back pressure leading to Turbo damage among other things.
Does it not click or anything when you try to turn it over?

If its a good specialist they will tell you what's wrong.

White smoke doesn't sound good at all. That's going to need recovering to a garage and proper diagnosis I'm afraid.

PS- what's with this new fangled trend for chucking in a fuel additive when a car starts acting up? If it were that easy no one would ever sell spanner again.

It turns over and 'wants to start' but never quite kicks in.

I hope its the diesel pump that has gone. After it happened I pumped the prime pump on the top of the engine a few times and then tried to start it. It 'Nearly' started but never quite kicked in.

ha-ha. Yea. I thought by putting in the Millers that I was doing good. I'd heard about dodgy Tesco fuel before and it AP Fault came on and started hesitating after I filled up with it..

So you didn't get a diagnostic done? The car was trying to tell you something was wrong :rolleyes:
Wait until the diagnostic comes back it could be a number of things hopefully something simple.

I know. The scan was due to be done last night but I was racing my bike in Rhyl so could not make it for the scan.

Forte is no good for Wipers.. Get some Millers Ecomax! :D

I know lots of people say to keep clear of supermarket fuels but not all supermaqrket fuels are bad. I've run a Honda FRV on Tesco diesel for four years with no issues. I also ran a 2004 Laguana and two 307's on Tesco diesel with no ill effects. The fact this happened after you used Tesco fuel is nothing more than coincidence. The same issues would no doubt ahave occured at the same time regardless of wether you used Tesco, BP, Esso, Shell Nitro+ or even witch p**s.

Failing to follow up the initial warnings quickly enough is probably more of a contributory factor than using Tesco's fuel.

I was going to sort this for the OP. He contacted me to say the EML had come on after a tankful of Tesco diesel but then went off.

As he lives five minutes away we were going to hook up Planet just as a precaution.

right some good news and bad news. :rolleyes:

Car will start and run with Easy-Start but will not start on its own, so at least the engine is still working :thumb:

There are a lot of fault codes but they said they could possibly be from when the car "died" and we were trying to start it.

Get live data readings for fuel pressure etc while cranking this is much more useful than codes codes generally tell you what has already happened live data tells you what is happening NOW :)

Okay cool cool. Will ask them to check if that's possible tomorrow.

One thing the mechanic was saying was that he thought the engine was turning over too easy as if there was no compression!

What could cause a loss of compression/pressure that would make the car not start?

Low compression would make it hard to start could be caused by various things belt having jumped a few teeth for example but again live data readings will check cam and crank sync although if 16 valve it also has a chain that can jump too :(

If belt has jumped teeth and especially if 16 valve it will have broken some rockers meaning some valves are not opening but this would not really explain the smoke.

thanks mate. when they got the car running with the 'easy start' the garage said it seemed to run normally and it did not seem like the belt had jumped. :confused:

I normally always use a bit of millers but did not have any this time round when filling up..

Okay anyway. Slight update on the dead car. Popped into garage while I was out training before.

They have found that when cranking the engine there is no fuel getting through the Diesel pump? We know there is Fuel getting to the self prime unit and to the Diesel pump but not through it.

Hopefully that could be the reason why its not working.

Obviously that was "possible" fault and not 100% confirmed but at least its progress :) -

Am I right in thinking this is the Diesel Pump below? Not bloody cheap are they :eek::eek: -
