It is liable to be only 1 of the 4 Spark Plugs in Cylinder 3 that this happens with.

This might be the Spark Plug that fails prematurely, and this will be the cylinder that then has loss of compression.

 

If you have Excessive Oil Use, Skoda UK Customer Services have been known to Refund the cars owner / driver and then have a 

diagnosis carried out to confirm the Excessive Oil Use is due to a Fundamental Design, Manufacturing, Component Choice, 

& Quality Control.

If you have a Manufacturers Warranty be sure that you use your Legal & Consumer Rights and get a Vehicle Fit for Purpose,

and that the Manufacturer deal with the Faults from the product they built and sold.

 

this link which was compiled by REVO will give you some idea of some of the faults, failures and possible issues since the Volkswagen Group released this engine with Euro 5 Emissions.

The reason for this link is that  no place do the Volkswagen Group compile the various possible failing of their engine.

They also do not give any information publicly on possible fault solving and attempts at resolves to reduce the high oil consumption 

where someone does have a badly manufactured engine which might need upgraded parts or even replacement.

THREAD TITLE: vRS Mk. II 1.4 litre twincharger oil consumption issues

 

SUMMARY

 

The Skoda vRS Mk. II uses a 1.4 litre twincharger engine. There are two variants of this engine - CAVE until 2012 and CTHE from 2012.

 

Page 145 of Owner's manual (LINK) includes the following observation:

“The oil consumption may be as much as 0.5 litres per 1,000 kilometres depending on your style of driving and the conditions under which you operate the vehicle. Consumption may be slightly higher than this during the first 5,000 kilometres.”

 

There have been a number of instances of this engine using more than ½ litre per 1,000 kilometres (621 miles). This does not apply to all engines and the reasons for the problem are not clear.

 

Following an oil consumption test Skoda have tried various remedies to reduce this oil consumption.

 

 

WHY SHOULD YOU CARE?

 

The most obvious short-term result of excessive oil consumption is that you as owner / driver will have to pay out to replenish expensive oil. However, there are other consequences, the plugs are likely to be covered in soot and oily deposits with the potential result of damage to one or more, most likely in cylinder number 3. The valves may also be covered in soot and oily deposits, the exhaust may suffer damage.

 

If it can be demonstrated that your car is suffering excessive oil consumption and you are still covered by the Skoda warranty you will be entitled to get the problem resolved at Skoda's expense. If you have additional warranty cover you may find yourself embroiled in some debate as to whether you are the victim of a known manufacturing problem but you should still be covered. If your warranty has expired you may be lucky and find that Skoda will make some sort of contribution towards the cost of rectification. The nightmare scenario is that you might find yourself faced with the need to get your engine replaced at a cost of thousands of pounds!

 

 

THE TEST

 

If you believe that your vRS is using an excessive amount of oil, you can ask a dealer to conduct a test to determine whether or not it is within the limit. They may try to charge you for conducting this test, it is quite likely that if you are well within limits they will insist on your paying for the test.

 

The test consists of draining the oil; replacing the filter; putting in exactly 3.6 litres of oil; draining and weighing the oil; replacing the drained oil; sealing the oil filler and dipstick; having the owner drive a few hundred miles; draining and weighing the oil for a second time. By comparing the weight of the oil before and after the mileage covered, this somewhat crude test should allow a calculation to be performed which will show how much oil is being consumed per 1,000 kilometres.

 

If the test is carried out on your car you should insist on being given a hard copy of the test results and receiving a detailed description of the exact procedure followed.

 

 

THE ATTEMPTED REMEDIES

 

The most extreme attempt at a remedy is to replace the engine or part of it. Other than that, there have been various attempts over time to solve the excessive oil consumption such as replacing the piston rings, modifying the breather and applying an ECU update.

 

The most recent and potentially promising fix involves fitting different oil spray jets (squirters) which are mounted just above the crank, point under the piston skirts and spray the underside of the pistons with oil to cool them.

 

 

CHECKING THE OIL LEVEL

 

It is advisable that you should regularly use the dipstick to check the oil level rather than relying on a warning light. The manual gives the following advice on checking the oil level:

• Ensure that the vehicle is positioned on a level surface and the engine has reached its operating temperature.
• Switch off the engine.
• Open the bonnet.
• Wait a few minutes until the engine oil flows back into the oil sump and remove the dipstick.
• Wipe the dipstick with a clean cloth and insert it again to the stop.
• Then pull out the dipstick again and check the oil level.

The oil level should be within or fractionally above the hatched area, NEVER below the hatched area.
If the oil level is within range A (above the hatched area) no oil should be added.
If the oil level is within range B (within the hatched area) oil CAN be added. This may bring it to just above the hatched area.
If the oil level is within range C (below the hatched area) oil MUST be added.

 

Skoda typically use Castrol FST Fully Synthetic oil.

For Annual Fixed Servicing the approved oil is VW 502 00 (5W-40) -or- VW 504 00 Long Life Full Synthetic. (5W-30)

For Variable Fixed Servicing it is VW 504 00 Long Life Full Synthetic. (5W-30)

The oil capacity is exactly 3.6 litres, you should NEVER overfill.

 

Operating temperature probably means about 80°C; God alone knows what "a few minutes" means; frankly checking when cold makes more sense but there you go.

 

 

Other details some of which it might be worth including are:

• tips for persuading a dealer to carry out the test and not charge for doing so
• contact details for possibly relevant people at Skoda

I don't know who (if anyone) it is worth contacting at Skoda?
