Hi there, 

 

I have been made aware of the injector issues regarding the MKII Superb - apparently due to it being assembled in India.

 

Long story short I was driving home in heavy rain last week and I got a light on to say the injector was gone on cylinder 3. 

 

Just wondering if anyone else has had a similar issue during heavy rain? I'm worried the fuel was contaminated with water and now I will be in line to change all 4 at €500 a pop!

 

Or hopefully this is just general wear and tear on a car with 160kms and it was just coincidental that it happened in heavy rain! Heres hoping anyway.

 

Any history or similar stories would be appreciated so I can fill in the gaps, thank you. 

Think we need some more information - which model year?Petrol? Diesel? Which engine..?

2012 1.6 Diesel Greenline - 160kms on clock

I would be checking the wiring first before getting worried about replacing 

They are not a common issue on these engines

I got a new one replaced at a cost of €490 fitted. 

 

Is there anyone that reconditions the old ones? Might keep it as a spare considering the price of them!

Also does anyone have any theories as to why the injectors go so easily in the 1.6TD and not the 2.0TD? 

 

I have seen some commentary online that some parts were made in India.

 

I had a theory myself that the injectors and other components are working overtime in the 1.6TD to get the emissions down to stringent EU levels - and if you remapped it you might get longer out of the various parts. Anyone have any thoughts?

More power means pushing more fuel into the engine, so the injectors and turbo have to work harder than they did before. You could probably just make that argument for emissions control components (EGR, DPF) if the soot loading was reduced by the remap, but it's pretty common for soot loading to go up after a remap, so they'll work harder too. The only relief you might get in a remap, if the tuner knows what they're doing and are willing to modify it, is to change warmup behaviour so that it happens more slowly. The standard map is designed to get as much heat into the DPF as quickly as possible so it runs a very aggressive warmup map: you might be able to adjust this in a remap, but that'd be down to finding a tuner that knows what they're doing.

I have an experienced tuner that has done the 1.6TD remap to 140bhp before. 

 

I was talking to a lad and he said you can get rid of DPF and EGR and write it out of the map also so it doesn't flash errors. How stringent are the NCT emissions regs? I would rather not pay Skoda a couple of hundred quid to clean my DPF and replace the EGR if I dont have to. 

I cant offer loads of help, but my 2011 1.6 has dropped injectors 3 and 4 within the year.

3 was most recent and in the rain but I dont think the rain was to blame, the car has been through far, far heavier stuff than that.

Mine has 150000 miles on the clock now so I have put it down to age.

I have spoken to a few people about it and haven't heard great things about the longevity of Siemens piezo injectors, a friend had them In a different car and had nothing but trouble, evidently it's the electrical side of the injector that gives up, so it's not even something that cleaning/servicing will help with.

Have you had the EA189 emissions recall carried out?

 

Where are you both located @skodaAH2019 and @Woosh, updating your location in your profile helps in these situations.

 

The EA189 recall is known to put additional strain on most of the fuel system and emissions related components, and if you're in the UK then there is a possibility your car is covered by Skoda's Trust Building Measure...

Hi Silver1011, I'm in southeast England, mine has never had the work done, I got a letter but even when chased got nowhere.

Having since read into it, I may well just avoid it anyway. I've seen plenty an account where people have had it reversed.

I am located in Republic of Ireland. However the car may have been imported from UK I am not sure. 

 

The car constantly feels like its being held back or restricted by the fuel map. A 1.6 TD should be a lot more powerful than 106bhp. For example my parents have a Golf 1.6TDI Matchline and it is 150bhp as standard. Surely this has something to do with it chucking out injectors at an abnormally high rate. 

From what @whoosh mentions above, it seems you're not alone. The Siemens piezo injectors fitted to the 1.6 TDI might be more problematic than those from other manufacturers?

 

A common fault with diesel fuel injectors is from contamination or by general wear and tear, as the nozzle can become blocked with carbon or foreign matter. This is a common problem if variable quality fuel has been used.
 
Another common fault by contamination or wear and tear over time is that the pilot valve within the common rail injector gets worn which causes your injector to back-leak which causes your vehicle to stall, run rough, have lack of power and eventually not run.

 

Sounds like it is simply wear and tear. Whilst 160,000km / 100,000 miles isn't excessive by modern standards, it isn't unusual to be having to pay out for things like injectors, EGR's, DMF's, DPF's glowplugs etc.

 

I'm not sure what type of injectors my 2011 2.0 TDI CR140 had fitted, but I sold it at 160,000 miles with no issues.

Just a further note, for piece of mind I spent out and had my remaining two injectors changed, it has transformed the car, pull much harder and more consistently, especially at lower RPM. 

I think it's safe to say the injectors were all just worn out.

The version of the 1.6 TDI fitted to the Superb is 105 bhp. Different models got different tunes, so you can't necessarily compare.
