Glow Plug Problems - Advice ?
Discussion
I have a Hyundai i30 Automatic, 1600cc diesel engine. In April 2015, I had problems in starting the car.
I took it to the Hyundai dealers and they replaced the glow plugs under the 5 year warranty, the car
was nearly 5 years old and had done about 57K. The dealership said that they had replaced all four plugs.
Recently I had the same problem, the car has now done about 62 K miles. he Hyundai dealership quoted a
price for removing the old glow plugs and inserting new ones.But with one provisor, if the glow plugs snapped
again then the cost would be in the region of £1,500, to take the engine out etc.
So once the mechanic had started removing the plugs there was no going back.They refused to give a 12 month
warranty from the first time when they first supplied the new plugs in April 2015.
What I want to know is this: Is it usual for glow plugs to "Go" within about 10 months and 5K mileage?
What do you think are the chances, of getting these glow plugs removed, without them breaking and having to take the engine out?

There is no simple answer for either issue.
If they fitted the first set and put anti-seize on the threads when they fitted them, then I wouldnt see too many problems removing them this time.
They probably didnt though.
And whilst they shouldnt fail so soon....it isnt to say it cannot happen.
Have they actually carried out any tests to determine if they are not working though ?
And if things seize and break...it can turn into a major cock up. Every engine will be different though, some easy some not.

The Glow plugs shouldnt go at 5K Miles if the vehicle was under average usageI took it to the Hyundai dealers and they replaced the glow plugs under the 5 year warranty, the car

If the vehicle was started and stopped 100 times a day over those 10 months and 5K miles then they would very likely fail
If the threads were supposed to have anti-sieze applied to them and that wasnt done you would then have a claim against the garage for poor workmanship
You mentioned somewhere that it was said "it looks like the plugs have failed", the plugs can be tested individually to prove which ones have failed, plugs very rarely all fail at the same time, sometimes the same plug fails time and time again
If plugs keep burning out it can often be caused by a heater plug relay/ECU fault keeping the power on the plugs all the time or at intervals even though the engine has started
Did the vehicle do 57K Miles on the original plugs? If you know and the answer is yes, get your thinking cap on
Very unlikely the plugs would have failed after 5k as others have said, unless they used the cheapest of the cheap replacements. More likely a fault with the relay/ecu for them and/or wiring I would have thought.
The trouble with the dealer is they'll probably just plug their laptop into it and go on that rather than making some basic electrical checks.
I'd complain since it's within 12 months of the work, or take it to a good auto electrician or specialist instead.

If the glow plugs are reasonably easily accessible then they are very quick and easy to test with a basic multi meter - the resistance should be less than about 1.5 ohms. If they are faulty then the figure is usually vastly higher than that.
When removing glow plugs it's very rare that they break because the thread is corroded / seized.
What happens is, carbon builds up around the glow plug aperture inside the cylinder head, then the plug snaps as the top part is twisted to try and undo it.
There are tools specifically for removing broken glow plugs, and if there is sufficient access the head need not be removed.

I would ring Hyundai UK or whoever is the importer, ask for their customer service dept, calmly state the facts of the case and ask for their opinion of the matter.
They will probably be non-commital but will investigate further.
5K miles is definitely not a satisfactory life for OEM quality glow plugs IMHO.
As Hyundai dislike poor dealers even more than the public do they should investigate whether the warranty claim was executed correctly.
Importers give goodwill warranty claims ( especially where the dealer is deemed to have been at fault),
but rarely admit the problem existed either with the vehicle or dealer !
Hope you get your problem solved without unnecessary expense.

This ^ and do what Auntieroll suggests The trouble with the dealer is they'll probably just plug their laptop into it and go on that rather than making some basic electrical checks.

I have contacted Hyundai, technical Dept, via email, and got a reply from a very pleasant female, who said the franchised dealership should be able to sort the problem out. I could not get any further technical information from her.
I have been to a service depot and asked them to replace the glow plugs, but NOT Hyundai make. I have yet to start the car up form cold to see if the new glow plugs make any difference.
I have have noticed that when the glow plug light come on in the dash, it illuminates for about 5 seconds, the new plugs probably about half a second longer.
Looking at some information on the WEB, it appears that the glow plugs should remain on for about 10--15 seconds. Does anyone
know if glow plugs in my car can be made stay on for longer. (.i.e. the dash light remains on for longer? ) or does it not matter?

Thanks for your help. I have contacted the Hyundai dealership, they will be looking at the problem, over the next 5 days, free of charge, they will let me have a courtesy car during this time.(car now out of 5 year warranty)
Looking at different forums, on the subject, they suggest starter motor problems, or a new fuel pump, and filter plus other suggestions,.
It looks to me that if Hyundai don't come up with a solution to this problem, the worse case scenario, is that I could be throwing £100's at the car to get it right.
I have contacted Hyundai H.Q. With this problem, only to say that the dealership, should be able to sort the problem out. I would strongly suggest, that they know about this problem and possible remedy, but are reluctant to talk about it.
Do I cut my loses, and buy a used petrol engine car, as the car's mileage in the last 12 months or so has dropped to 5000 miles per year?
The part exchange rate for this car is - £2500 to £3000.

Diesels are great these days...when they're working. They're power delivery can also make knocking about quite good.Looking at different forums, on the subject, they suggest starter motor problems, or a new fuel pump, and filter plus other suggestions,.

But when they go wrong, they can cost a fortune.
For such low miles I cant see any real reason to own a diesel. You'd easily find a modern petrol that will probably cost far less to run unless a lot of those miles are stuck in traffic, in which case a diesel will still use less fuel.

I ran a car with a dead glow plug. Started fine. I'm guessing GPs aren't the issue here
Some will, some wont.About 20 years ago I fitted an old 2.5 Isuzu engine from a pickup into an old car to knock about in. Never did wire in the glow plugs, and it started first time every time in any weather !
f
k it was slow though.And old Rover 2.0td I had only had 3 glow plugs installed, the 4th would ahve been behind the injector pump so almost impossible to access and it seems Rover decided not to even fit one there. ( head not drilled, so no accident either )
Yet other engines...even with 1 plug down and it can be a nightmare to get started
A number of members have asked "What is the starting problem?'
When I start the car up from cold, in the morning, I let the glow plug light go out on the dash.
I then try to start the car, it never (or hardly ever) starts first time. The second start up, it usually starts.
During the rest of the day the engine starts up first time.. I checked the voltage of the battery about
2 weeks ago, whist the engine was NOT running. The voltage was 12.89, which appears to be Okay..l
I have had 4 new glow plugs fitted, as the Hyundai dealership suggested, but the problem remains the same.

Does the engine turn over ? how fast does it turn over ? What is battery voltage when it is turning over ?
is this all the time everywhere when cold, or just sometimes ? etc etc etc.
