VW T5.1 excessive oil use

[hoddy]

Ok, I've got a plan.
2010 5.1 is leaking oil due to engine damage from EGR. Engine still runs well but comes up with fault codes / limp mode etc.
First step - prevent further damage
----> gut the DPF, blank the EGR, remap ECU and maybe a performance tune for a bit of power.
Second step - oil change maybe with a thicker oil to prevent excessive oil loss.
Third step - maybe can live with oil loss as long as engine still ok. If engine gets worse then I'd need a new engine but would not need DPF or EGR replaced as these would have already been dealt with.
Booked to have it done next Friday.

I spoke to a German mechanic the other day he specializes in VW AUdi BMW Mercs only , I broached him about EGR blanking DPF etc . He was very knowledgeable about possible problems that may occur down the track after around 20 to 30thou km after the mods are done . Apparently the EGR and its cooler is designed to keep the engine operating temp in a very defined range , without the EGR that will change and over time can lead to piston failure .

I would have thought it would run cooler, which is a good thing for Australian climate. And s free flowing exhaust can only be a good thing as well.
Given the engine I've got already has cylinder wear, and the DPF might not be in great shape neither, so I don't there's a lot to lose.

You can only work with that is in front of you, its worth a shot.

I had a older tractor and it needed new rings, but of course they were as rare as unicorn ****, and i wasn't able to source them anywhere

so i just used a heavier oil and it did the job.

Update:
Van has been getting worse last 2 weeks. DPF light coming on all the time, and going into limp mode quite a bit. Have been able to clear fault codes while driving using the VCDS, which is good for taking off from lights, going uphill etc.
But still bloody annoying.
Rather than a new engine have decided to gut DPF and blank EGR.
Just picked up the van from having this done. I also opted for a REMAP as well - why not - the engine needs replacing according to VW.

WOW - the van is punchy lively and has more power than when it was new! Am stoked.

Next step is to flush the oil out, along with the ferrous / silicon / crap from the corroded EGR.

Will change to a thicker oil - liquimoly 10W40 - which might reduce some of the oil consumption (was 1litre per 1000).

Will see how this existing motor goes - might still last some time.

How much approx. ?

[Bryn23]

awesome, hope you get more km out of the engine.

New oil will help, but interesting to see if does reduce the oil consumption.

would running a engine flush agent in the existing oil, help before new oil?

[hoddy]

How much approx. ?

It was $1300 quoted. But negotiated a bit less.
Includes: Gutting of DPF, blanking EGR, software deleting, Remap/ tune.

Given VW quoted over 17 K for new engine / DPF / sundries I reckon it's a no- brainer.

Local mechanic is going to sell me 20Litres oil, filter, and stuff to put in old oil before change. Apparently u let it idle for 10 mins with this stuff in, and then drain.

Sounds like a great plan, that should help clear out the crap in the current oil.

All up, its a risk worth taking, considering the cost of a new engine... i still can't get my head around $17k

... i still can't get my head around $17k

I know. It's like the quotes keep going up in 5k increments everytime someone posts here. I've decided to keep my 2010, in part because I didn't want to offload such a potential timebomb onto some other poor unsuspecting soul. I think I've decided when I get my first repair bill I judge is not worth paying I'll just wreck my vehicle and then try to find something else simple and reliable that I can stand to drive...or ride a bike

A few guys on the CFCA oil FB page have now done the complete DPF EGR delete with some pretty good results. One of the guys has put larger oil coolers on to help but his van never goes over 95°c and runs like a trooper. I've had my first oil test come back with high Ai & Si but I hope it's because the EGR was replaced half way though the service. It's now had another complete VW service and I need to do 5000km before the next test to see how the EGR is performing.

It would be good to have a proper temperature gauge in these vans!

DISASTER 2.0L T5 2011 Oil Consumption

EDIT: Head to page 8, you will find two people who have had the issue repaired under goodwill (both 2nd owners AND out of the warranty period), there is also a link to a facebook group, the group has details on which code you need to lool for on your EGR cooler if your motor is using LARGE amounts of oil, see my original post below...

Hey Guys,

Just found out my ex ambulance engine has broken/worn piston rings and needs a replacement. It sucked through 5Litres of oil in 2000kms

I know theres a thread somewhere on here about someone elses who has had the same problem.

Its the CFCA engine code. 2011 T5.1 2.0L Biturbo 132KW model

Has anyone managed to replace theirs?? and cheaply? I have found a couple of replacments on gumtree and ebay. But I want to fit it out as a camped and am scared it will just happen again.

The guys above supply a rebuilt motor which they claim will not lose oil.

Any ideas?
