Ok, totally newbie here, and just after some advice. My 65 reg Octavia started burning oil, leaving clouds of blueish smoke behind me, then the engine light came on, it was overdue for a service anyway, so took it to a local garage (not skoda specialists)

Diagnostics came up with a whole range of codes, but the main one was the egt sensor 3, this was replaced, and topped up with oil,

A DPF regeneration was done but on the road test, it was still smoking and used almost 4 litres of oil, the replaced sensor was also burnt out. The garage have basically said that it's looking like a new engine and turbo, but does anyone have any ideas before I take it in as I really don't want to be ripped off. Be gentle, I'm not the most technical of people! 🤣

Just for info, this is a picture of the codes found during the diagnostics

Difficult to pin point but worrying areas from the codes look like:

 

* High Pressure Fuel lines are reporting too low pressure (fuel pump or blocked fuel filter??).

 

* Turbo charger various faults. A blown turbo will exhibit the faults you are reporting.

 

The fact that sensors are failing sounds like they are failing due to oil saturation. The 1.6 or 2.0 tdi engines are good units if looked after. 

 

I would check to see if you also have oil in the coolant (blown cylinder head gasket) or the timing is massively out (indicating engine trauma). If none of those, then most likely a blown oil seal in the turbo. 

 

Any reason why you didn't take it to a Skoda Dealer?

 

Thanks for your reply, doesn't appear to be anything in the coolant, but sounds expensive regardless. The only reason it didn't go to the dealership is that the nearest one to me is about half an hours drive away, and I wasn't sure if it would make it, as it kept going into limp mode, and I don't know enough to know if it was safe to keep driving. Gonna have to bite the bullet though.

Thanks again 🙂

Sounds to me like its probably worth checking the Turbo.

It's a big bill to replace, but a whole lot smaller than a new engine

 

Step 1 - To check for head gasket a simple test is to look into the coolant bottle (Cold engine) and see if there are any oil deposits in there or it is an odd colour.

Step 2 - Check the dipstick and oil cap for white mayo type deposits in the oil.

 

Either of those signify that coolant and oil are mixing, which is a typical sign of head gasket failure. Smaller failures do happen that don't show this, but it's a simple check.

 

Step 3 - Check for oily deposits around the engine bay/undertray.

 

 

Before you go anywhere, check the oil level, make sure you have 1L or 4L of the correct oil in the car and breakdown cover. Also keep the revs low, so you're not using the turbo where possible (Below 2000 rpm).   Alternatively just call the breakdown cover for a tow to a dealer or VW specialist.

 

It might be worth asking for recommendations of VW specialists in your local area, as if it is the turbo, then it's going to be a sizable bill should you get the work done at the dealer.

 

 

 

 

 

 

 

Thanks so much, this is perfect!
