Recently had a minor oil leak on my Yeti 1.2, the low oil level sensor did not detect low oil level so ran low on oil.

Recovery to local garage who repaired leak which was coming from a plastic cover on rear of engine, oil filter also replaced as it was blocked.

After driving car for 2hrs, red oil pressure warning indicator came on, stopped car checked oil level, which was O.K, no noisy tappets either.

Restarted car, fault condition cleared and drove on with no problems with engine, low oil pressure lamp came on again on return journey.

Same as before, stopped and restarted engine after checking oil level. Back to local garage who replaced oil pressure sensor, but this has not cleared the problem which reoccures

after driving car for a couple of hours, around 120 miles. Also noticed engine is very hot and will not always start straight away, O.K from cold.

Have been advised the problem could be caused by oil starvation as opposed to oil level & pressure.

Has anyone experienced similar symptoms, any suggestions or advice will be most welcome, as I don't really want to get rid of the car. My local garage have advised an engine rebuild with new parts is likely to be in excess of £1.5K!

I'm concerned that the oil filter was blocked. I'd be looking at that again if I were you, then onto the sump removed and check the oil pick up pipe.

I had this happen on an old Golf GTI. Fine until the engine was really hot, then all the crud on the bottom of the sump was sucked up and blocked the oil strainer. Totally did the engine in, con rod through the block. Get the sump off asap and clean it out along with the oil strainer. 

Sounds like the normal 'fail' on the 1.2 TSI of leaving behind the old o-ring when changing oil filters.

Filter needs removed to check.

PS

Re Faults ,

or as it is, just a Low Oil warning or Low oil pressure are not cleared, just you open the bonnet for 30 seconds and the lights or message might go off for 60 miles.

The oil is still low, or the oil pressure is low.

That should not happen unless wrong/crap oil used or very infrequent maintenance.

Very true but the symptoms fit exactly. My Golf had no symptoms at all until I took it on the motorway and got it really hot, oil light came on. Took it straight to a dealer to check the oil pressure, checked fine, the light had gone out as the crud had dropped off the strainer. Went back on the motorway, ignored the light and wrecked the engine. It was an old motor, I had done oil changes as required but the previous owners obviously had not.

The OP that had an oil leak and then a oil filter changed has describe what sounds like a oil filter fitted without the 'o' ring removed.

But it takes under 15 minutes to find out. And the person that made the error to apologise.

At least! And refund any charges related to the oil pressure switch change, if the filter error is confirmed.  Watch out for waffly coverup stories if you do take it to the same place for this to be checked.

If that wasn't the case before, check carefully that it completely goes away after the oil pressure problem is resolved.

And, indeed, the checks for the extra O-ring should be done at no charge.

That sounds more like a cooling problem.

Stripped the engine afterwards, loads of crud in the sump which was clogging the strainer.

1.2tsi cbza/cbzb engines

 

These engines are not known for sludge or debris build up in the sump, the chain would have expired long before that happens. 

 

90%+ likelihood that they just left the old oil filter O ring behind and this gives this symptom.

 

To the OP, do not continue to drive until this is resolved, the oil pump is currently returning most of the oil to sump straightaway without going round the engine. There is likely very low oil pressure/flow through the engine, the warning light comes on when the pressure is virtually nil. So camshafts/bearings/followers/high pressure fuel pump, valve seals, crankshaft large/small end bearings, piston/cylinder walls, turbo bearing, chain already may have all suffered damage. Driving with no or extremely low oil pressure is more than often terminal.

 

Get that oil filter off and fish out the extra O ring out asap!

 

If you cant DIY, make sure you witness the mechanic doing it in case there's any denial/cover up. Its only 5 mins to do. This engine has the easiest oil filter removal/refit of any engine (though a filter removal tool is usually required because of over tightening).

 

Then think about what compensation is due for negligent work and possible consequential damage to your engine.

^ Just adding an @ZouchM to hopefully bring the OP back to this thread to read the above.

A progress report will be good once there is some.

That was only possible if 50 years ago or no maintenance for 10.000s of miles, not on a modern engine with the correct oils.

It was 1997 on a B reg Golf GTi Mk2 with a lot of miles on the clock.

And I've seen it on a 1995 Vauxhall with high mileage and uncertain history (originally a company car, so probably minimally serviced even early in life).

Many, many cars on the road - even with modern engines - have poor or non-existent servicing.

 

Many people come into my wife's workplace and by the cheapest oil they can, because "oil's oil".

Can anyone confirm if the Yeti actually has an oil level sesor, or is it just a warning for low oil pressure, which is all most cars used to have.

 

As my car is parked on a steeply sloping drive I rarely get around to looking at the dipstick as I have to move it to a level area first.

It is just a low oil pressure warning.

I think all VW group cars that can be on variable-interval servicing have the oil level/temperature sensor.  If you have a display of oil temperature anywhere, then you have the level/temperature sensor.

Fairly easy to spot sticking up into/through the bottom surface of the sump, usually. 3-wire connection, if I remember right.

Which would be all very well, but my Octy (Elegance TDi110) has level and pressure, can be run on variable, but no oil temperature display.

I didn't say that an oil level/temperature sensor guaranteed an oil temperature display, just the converse. 

My Polo has nothing displayed, but I can query level or temperature with VCDS, and I suspect that the alert would trigger if the level were ever low.

No, on a Yeti there is an oil temperature sensor and an oil pressure sensor. There is no oil level sensor.

Evidence?

Cos I find that hard to believe.

Haven't got access to circuits just now, but look forward to scrutinising later.
