Glow plugs cannot be removed

[Robs1000rr]

Hi all
My t6 204 sportline went in to Vw to get no2 glow plug changed as was a fault on that one.
I said while you are they just charge all off them .
Got a phone saying two of them are stuck and did I want them to try and remove them but said if they break it will be around the 5k to get it fixed.
Told them no but can anyone advise a company who specialise on removing stuck glow plugs or do I have to bite the bullet and take the 5k cost to fix it.
Live in north east of England
Any help would be good
The van is running ok but now I know I have this problem would like to see if I have any other options open.

Glow plugs are for cold starting.

Did you have a drivability concern before?

How did you get the no2 glow diagnosis?

Google ‘glow plug removal specialist’ or ‘injector removal specialist’. There are plenty.

Hi all
The van drove ok and stated ok but just kept throwing engine management light on all the time after resetting the light . Kept coming up with no2 glow plug circuit on my code reader.

It won’t be doing any harm but as winter sets in you might find the engine is firing on three cylinders when first starting.
Try soaking the seized glow plugs with a good penetrating oil, apply while engine is warm but not full running temperature and avoid driving for at least a few hours, preferably overnight.
Do this daily for a couple of weeks and then have another attempt at removing the glow plugs.

Thank you will give that a go

After lots of penetrating oil for a few days ref DXX above, you should try and remove the glow plugs when the engine is hot. However, you need to fit the new ones when the engine has cooled back down.

The 5K cost to remove the glow plugs is when they have snapped in the cylinder head and ideally you remove the head so you can drill the old plugs out and fit thread inserts for new plugs to be fitted. It is possible to do this with the head still fitted as I've done this on a Ford Puma 2.4 but it takes a lot of time and patience and a bit of ingenuity to make sure the heating element can be extracted and no swarf drops into the combustion chamber.

It worth noting that when glow plugs do snap, its above the thread so you can continue to drive the vehicle, it just won't start as well and will throw up errors when it tries to use the plugs as part of the post-heat emissions reduction function.

I had this issue in October last year. Faulty glow plug. My local garage managed to remove/replace two, a std plug and the sensor plug. But despite days of soaking the other two wouldn't budge.
Happily this faulty plug had no affect on the driving. Sadly I had a similar issue with my Passat a couple of years ago and the engine went into Limp Home mode. Very frustrating to have no power and hold up traffic on the motorway as the car had no power, for something that only heats the cylinders in cold weather....

Did you manage to get the glow plug. Currently with the same issue.

No luck with mine stuck well in and do not want to move .

Thanks for the reply. I take it you haven't had further issues and just lived with it?

 

[Robs1000rr]

Given up on trying to fix it as running ok at the moment but just saving up so when it becomes an issue can sort it then or px it into dealers for a newer one .

My worry with leaving it would be the possibility of extra soot created on cold starts causing problems with the dpf. Maybe someone on here more knowledgeable than me could advise??
