Golf 7 TSI oil consumption

ahmedomar said:
I have a 2013 golf 7 1.4 tsi and it is now beginning to use up oil. In the past i never had to top up oil between services but now after doing 5000km after the 105000km service i had to top up and now again 2500km later. VW says it's normal. Is it really normal as it never did this before?

Normal

Its "normal" actually. To achieve emmisions and effeciency targets. tolerences in engines are actually a little "looser" to prevent too much friction. result is oil burns more than older tech where they a bit tighter and better sealed. Problem is that this "looseness" varies engine to engine.

my twincharged motor was also in spec until piston 3 said bye bye.

Is it normal according to us? no. is it normal for them. Yes it is. remember dieselgate? do what you must mein furer

Proof? That's complete bullsh*t.

How does loosening tolerances, which leads to blow-by help emissions? If tolerances are so loose in a piston cylinder, it means you have piston ring wear, and the rings aren't sealing.

Burnt oil causes carbon build-up and damages the cat. It pollutes too. That is NOT increased efficiency.

No other cars have this problem other than certain Golf Audi engines. It's a bad design. Burning oil is not a feature. It's a problem.

His car probably billows blue smoke too, which he thinks is normal.

BMW had a problem with their N42 and N46 engines found in the 1 and 3 Series from around 2004 to 2009 which had valve-stem seal issues.

The valve-stem seals would harden prematurely, causing oil to leak into the cylinder. This was identified by plumes of blue smoke from the exhaust, , most noticeable after idling for a while and then revving or accelerating.

I had this exact problem with my 1 Series, which BMW said was normal - but was an inherent design flaw. The only way to rectify the problem was to overhaul the valve guides, which was not covered by warranty. I had to fork out R35k+ to fix the problem at around 100k km in 2014.

The later models of the N42/46 engines were redesigned to combat this problem.

Well one could argue that if more of their cars do it than ones who don’t then it’s normal isn’t it?

I mean all of that being said even with the higher than expected oil usage (compared to other manufacturers and engines) it’s not like these engines don’t still last hundreds of thousands of kilometres without real issue.

They only seem unreliable because when VW/Audi fix the problem they end up rebuilding the entire thing at greatly inflated costs.

That doesn’t mean if it was left alone it would have had an issue down the line.

The truth is the Golf 1.4 TSI and early Audi TFSI engines don't last hundreds of thousands of KM's. These engines wear out prematurely... that's why they are burning oil! A worn engine burns oil.

Audi fixed their piston ring issue in their TFSI engines post 2012. It's well documented;

Oh no I’m well aware of it being corrected.

But I know of few 1.8T’s that had the oil problem and happily did over 200,000km and my own 2.0T was heavyish and did the same.

1.4’s seem to summer a premature death from simply working too hard.

Not really. Car was under maintenance plan. Never paid a cent apart from the time having to deal with various dealerships.

Dealership in Somerset west once forgot to put the oil cap back after a service. 1-2km after collecting the car there was smoke everywhere. Bunch of knobs working there.

The interns working at VW Bellville put the incorrect oil plug on my car during the oil consumption test. One would assume extra care would've been taken during such an exercise. Ended up with oil all over my driveway and another few hours at the dealership. A really frustrating time that was.
 
Compression test each cylinder and record readings.Then add a few drops of oil too each cylinder and repeat test.
There is a tolerance on dry readings and usually 10 % variance between each cylinder is ok.
If the wet cylinder readings increase a lot compared to dry readings then the issue can be oil blow between pistons and sleeves.Best is to consult a independant mechanic

This is what I found. Maybe he is wrong. it does make some sense to me.

My last car was a 2.0 TSI. I had it for 220000km from brand new.

After 100k km the wear begins and some oil usage occurs. Small top ups every 5k.

After 200k km it's much more than that. Granted the head was leaking and a fix later meant that it went back to no oil usage

Point is, the cars don't have gaskets but instead a green sealant that does crack after high mileage.

I still live my VWs even though I don't have one anymore.

On Friday morning there was a small puddle where the car was parked overnight yes. Otherwise no. But I'll take it in tomorrow.

That may be a good sign, these engines have exhibited issues with the oil cooler, have you checked to see if the oil and/or water have mixed? Where are you taking it in to?

Oil still looks good. That's the first thing I checked. Someone here advised silverton radiators. There is one close by so I want to stop there this morning. I noticed a puddle on the bottom cover also yesterday so I suspect something is cracked or loose somewhere.

Silverton Radiators are generally pretty good from what I have heard, I don't have personal experience with them. More than likely you have a cracked pipe or housing, common on many higher km VAG engines, I'll try find out where the 2.0 TDi's have common coolant leaks. Another thing to try, if you are using G12 or G13 coolant, it has a trace in it that shows up under black/UV light.
 
I think my radiator is broken. Just now greeted by a pool of water under the car and an empty reservoir. Wet spot on the side of the radiator.
 
Refilled, pressure test. Small droplet coming from fckng somewhere impossible to see. Will have to get this car to a mechanic. As if I can afford that now.

I will just drive until where ever this hole is gets bigger and hope it doesn't happen suddenly.
