VAG 170 PS Diesel Injector Failures - VOSA action

[Auric Goldfinger]

To be honest I don't know any more!

Did the problem get worse after the injectors were changed? Yes.

Was the problem there before and been made worse by the injector change? Possibly.

Is it actually the injectors causing the problem? Who knows!

I expect a slightly slower engine start in extreme temepratures but 3-4 seconds of cranking/spluttering isn't right.

The annoying thing is that there are others out there suffering this same issue.

After first fitting the new injectors they have been out on a number of different occasions to be checked and re-checked so I can only assume that they are happy that they are fitted and are working correctly. The saga continues!

Do you think it might help if " Someone else " i.e.:- another dealer had a look, they might just spot something that your dealer hasn't noticed. If they think they are fitted right first time, every time they put them back in they'll always put them back that way. Are the injectors made to fit in a special order or position or can the go anywhere, in and order

That was me, search for my 'Gritty Oil' thread.

I've since had the oil and filter changed and will be watching the level very closely to make sure that it isn't still rising.

jrw, was the diesel leaking out onto the ground or into the sump?

Well I've had my injectors done on my car on the 28th dec 2011 and I've had nothing but problems with the car. After I got the car back it cut out coming up to around about and it's feels really restrictive and not wanting to go. (if you get what I mean). So I phoned skoda up who said bring it back to the garage and they would have a look. In the mean time I popped open the bonnet and found diesel leaking from the fuel flitter. So I took it back to skoda who said that the issue had nothing to do with them and it was like that before they had a look at it. So I took it back to another garage who put a new fuel flitter in and it's been ok until yesterday when my exhaust control warning light came on. Do you think this has anything to do with the injectors and for the car feeling very restrictive?

Cheers rob

No need to touch the fuel filter when changing injectors so would on the face of it just seem like bad luck.

Ross - sorry, the answer to this is probably already buried in these 38 pages, but... My car is going to be checked to see if it needs new injectors in a couple of weeks when the MOT is done. To check if they need replacing, do they have to remove the injectors from the head?

Onto the ground - there was a puddle on the drive when she reversed off to go to work apparently.

They have to remove then cam cover to check the part number but not the injector.

Thanks

If after the inspection they are covered under the recall ask them if you can just have the new injectors to keep at home in the garage, they'll cause less problems there

[rustyGT]

Surely these problems have to be installation related...??

Mine struggled to start this morning in -2 temps, the first time it has struggled.

im also pleased to report no further DPF problems after my initial lot, I ran a tank of diesel with DPF cleaner it so maybe that snake oil has helped!

I'm also quite happy to report that, although my DPF issues havent gone away, since my full tank including a bottle of JLM DPF cleaner my problems seem to have settled (although not gone away completely!)

my step dad has a 170 pd vrs estate. got a call from dealer last week regarding "upgrade" of injector for free out of warrenty. dropped it off this morning and will hopefully be picking it up this afternoon.

Picked up my VRS TDi today and looking in the back of the service book under 'workshop entries' it was in for 'recall 23J7' on the 30 december last year at Lightcliffe Skoda in Warrington. Is the injector recall?

[Davidsr20]

They put a sticker in my boot floor to say the we're done.

[hatchy]

Sent an Email in the end to Lightcliffe Skoda and they can confirm that recall 23J7 was the injector recall. That's a weight of my mind that it's been done.

No known cure as yet I'm afraid, see here:

Mine's still like it too. Just haven't had any time to investigate further.

Hi Guys,

I have 57 plate Skoda Octavia vRS 170bhp and only had 4 months when the car cut out suddenly on the motorway doing 80mph. It was injector No.1, had it replaced by non-dealer, however I got in touch with Skoda UK and they're refunding me the costs and local Skoka Dealer will replace all remaining 3 injectors for free.

If you have this model car then ring your local dealer and get a new set of injectors for courtesy of VW group.

Good Luck

[silver1011]

Yep, that's pretty much what the previous 769 posts alluded to too

Glad you got it sorted, it's just a shame you hadn't seen this thread earlier and avoided a breakdown on the motorway.

I wonder how many other PD170 owners are out there that haven't been in for their FOC injectors...

[Nick P]

I wish I was one of those owners who haven't silver :(

[silver1011]

Me too Nick.

My oil cooler is leaking oil into the coolant.

What's the chances that the diluted oil caused by the incorrectly fitted injectors (that led to a failed turbo) has also damaged the seals in the oil cooler?

[Nick P]

you've got to wonder

[silver1011]

I was wrong, the two seals in the oil cooler are in contact with the coolant, not the oil, so I can rule out oil contamination as the cause.

The oil coolers are renowned for corroding internally apparantly. As the corrosion gets worse so does the amount of oil that escapes into the coolant.

I've been lucky by catching it early, the coolant is clean, there is just oil/sludge collecting around the edge of the header tank.

The guy at the dealer said that what normally alerts owners is the low coolant warning light, caused by the header tank being completely full of oil.

At this point it's a bigger job as flushing out the oil is a long job as it requires several flushes and a new header tank.

Skoda want £460 so I'm sourcing the part from a local motor factors and getting my friendly independant garage to do it for £40/hour instead of £90!
