Garage pulling piss?

johnty56

Dropped a 2007 Peugeot 307 1.6 hdi into a garage for my sister.

Had been going into limp mode, possibly after been driven with v low oil.

Garage are saying it is the glow plugs. The car starts fine, and the issue seems to start when the engine is warm.

surely the glow plugs are only an issue when starting the car, how would they be causing it to go into limp mode?

Any opinions would be appreciated as she is skint and really can't afford to be spending money on BS!!

Kopparberg Strawberry and Lime

It's very possible it is them.

If you want bring it elsewhere for a second opinion but that's more money

I think the glow plugs cause the same limp mode in the skoda's also...so it is quite possible.

Thanks for the replies.. just couldn
't see how the glow plugs could be the issue, but I suppose if is known that they can cause that issue then it may well be them!

I doubt it's the plugs. If the engine starts and runs ok for a while, then you don't need the plugs after that as it fires on compression. Has to be something else but I'm open to correction.

Might be better asking there

My Ma's diesel Ford Focus went into limp mode, garage said it was a dirty fuel injector fixed it but weeks later same thing again - She had to get all new fuel injectors,
Dirty/laundered fuel from no name garages was the problem she only buys diesel from big name garages now!

Modern diesels dont just use glow plugs on startup they are used untill engine is upto to operating temperature to help keep emissions down.

100% the glow plugs could cause this issue i only had a focus in this morning with the same issue.

Oh and good luck getting the plugs out of it in one piece that engine is prone to plugs seizing in the head.

I havent came across any 307 1.6 hdi that has gone into limp home mode with just glow plugs blown its usually another fault(s) that brings on limp mode.

Like that lads have said above the focus 1.6 tdci do go into to limp home mode with blown plugs.

What other faults apart from P1351 did they garage pick up..?
Is the 307 the 90 or 110 bhp engine...?

I have seen a 2005 307 and a 2007 407 in limp mode purely down to glow plugs.

Modern cars are designed to go into limp mode when anything that can cause an emissions problem goes faulty, it doesn't matter that it's an immediate problem or not. The idea is that you get it fixed and stop polluting the planet.

We had a 2007 S40 1.6D in this morning with the same symptoms as well and it was casued by the glow plugs.

On these HDIs, a lot of odd problems flag up from crap diesel. Garages will often diagnose ecu issues, glow plug issues, injector issues.. etc etc...people spend a lot trying to fix them.

Generally, instead of hurling parts at it, drain the fuel tank, , change the fuel filter and refill with clean diesel and a can of injector cleaner, and drive for a while...they "come back good..."..."amazingly"...this works so often that it is almost the first port of call..

Must be the changes in air temperature in the mornings.

Wont do much when you have glow plug faults and no fuel pressure faults.

Never! :P

My first vehicle when I was 17 was a 305 Diesel van..

Funny you lads mention the glow plugs.. We wired them through a relay (as the timing system messed up ) to a pushbutton on the dash. 5 "elephants" in the morning and 2 if she was sat for any more than 2 hours

You do this job to a modern diesel car and see the dash light up like a christmas tree !!

I used to have her full to the gunnels with home heating oil with a bottle of spry crisp and dry just to keep things right !!

Don't forget turning up the injection pump by a few turns. Massive trail of smoke and she'd go like the clappers.

Old Peugeots were desperate for doing that. Your one defiantly wasn't the only one with a heater button, that's for sure

The old diesel car would only light up the glow plugs for starting the engines

The modern Diesels can switch on the glow plugs when engine is running often to do with things like heavy loads so as to help stop the classic black smoke the diesel gives out under heavy loads and other reasons to complex to explain in one post .

IT would be logical to go into limp mode if something is not good . A example a O2 reading devise is dirty and isn't in the norms and so forth signals go to limp mode .

Tail Docker is correct that many problems in many diesel cars go away when the entire fuel system is cleaned out properly.

The Modern diesel fuel has typically ~7% bio fuel in it and many older and newwer diesels this stuff seems to gum up lots things especially if car isn't used in long periods .

In an older diesel Merc of my friend when we lifted the fuel filter after a one year stop to use it was mushy brown horrible stinky stuff there . We checked and it was all over the fuel system .

In the olden days this never happened with Diesel fuel as diesel fuel was 100% diesel fuel
The new EU mandated diesel fuels is bio diesel fuel formula and encourages growth of plants of some sort they call them algae or something and once this gets in the system it moves through the whole fuel system . Once in the fuel system it seems that it can grow back very quickly .

Changing the fuel and running through the farming diesel oil which has no bio fuel for few tanks cured that problem killed all the flowers in the tank and fuel system on the old fashioned Merc .

That farmers diesel fuel trick cant be done with modern diesel cars as the 7% bio fuel diesel hasn't got high sulfur content so that Particle filter can work .
The farmers Diesel will have high sulfur content and risk to possibly wreck the particle filter .

Also modern diesel car if they are the common rail inline injection system and the car spend most of its time running around in city traffic the hot fuel is returned to the tank .The fuel gets heated up as it passes into common rail and due to lack of fuel demand most of the returns back to fuel tank .This hot fuel has two bad effects .The heat breaks the bio fuel into nasty component that then go back to the engine later on engine . Also the hot fuel makes plants life grow more easily. Plant life in fuel systems can cause rich and lean running and the The Particle filter can start to block up from this unstable engine running

Also the normal reburn solutions might fail to kick in and particle filter blocks and puts car into limp mode .

It is really important if the car is used in heavy traffic during the week to go for a good burn in motor ways during the weekend to burn up this crap fuel and clear Particle filters
Then refill tanks to full to dilute nasty stuff in there .This also will help make the particle filter burn systems kick in.

Diesel cars that do mostly motor way driving during the week will be far less likely to get plant growth as most of the fuel from the common rail is used up and less hot fuel goes back to tank to poison the fuel

I dont think it special problem to Puegeut unless your main ECU brain has gone AWOL . However that normally shows up in different ways mostly refuses to start at all .
The ECU tend to go south after 7 years with most of them dead meat after ~12 years seems to be where pueguet seems to be at .
I just binned my petrol 1900cc 1996 convertible 306 due to untraceable engine running issues with management light on for months that I ran it .It was great fun for summer bought it for song and wasnt go to pay to repair it .Was great on highways smooth running but in town was chugging and blipping .Its Probably the brain was going south dont know winter is here too cold for covertable now
