Get it looked at, could be a failed lift pump which is not feeding enough fuel to the High Pressure Pump (which can cause damage and is expensive to replace) or a leaking injector(s) which could at best cause dilution of engine oil, at worst put enough fuel into one cylinder to cause a hydraulic...

The problem happens every 4 months so I’d need 3 oil changes a year at £200 plus an oil change and in between those I’ve have oil dilution and increased engine wear…sounds great for a £50k van There’s other issue like I’m going to Germany this summer for the football and will do 5000 miles but...

Absolutely must get that old oil tested to know exactly what metal is in that oil and the overall health of the engine. Bearing metals. Piston and ring metals. Cylinder surface metals. Could there be diesel diluting it. Soot levels. Assume you had a running in oil for first 500-1000kms and...

Thank you !

The oil sample from the failed engine maybe of limited value as the turbocharger failure will have introduced contaminants. If you are going to sample don’t do it from dropped oil, use a syringe and tube down the dipstick to avoid external contamination, probably the only data worth looking at...

Just had the latest analysis report back, very low contamination and viscosity very good, no recorded fuel dilution. 18 ppm Fe, 11ppm Al and 0.2% soot after 4772 miles on the oil. I wouldn’t mess about with mapping and Darksides DPF removal. The Tafmet solution is less than an hours work and...

@Ace has the vans oil level been increasing without adding oil? Valve gear wear doesn’t appear to be a common defect but if the oil were diluted with fuel reducing viscosity and film strength it could cause accelerated wear. Does the van have full service history?

My Mk7 golf is the 2.0tdi 150 and for the first five years was mainly only used for long journeys. It got high 50s in mpg and had no problems at all. Since lockdown and a change in work etc it isn’t used every day and generally for smaller around town trips, mainly ferrying kids to and from...

Monitor oil quality with oil analysis, disable STOP / START and being careful not to stop an engine after heavy acceleration would help prolong turbocharger life. Carbon contamination from EGR and fuel dilution from DPF re-generations is resulting in very poor quality oil before the oil change...

I missed that bit first time around, Run away, Long Life servicing is aimed at fleets with a company vehicle life of 5 years before selling off for others to suffer the consequences. IMO the synthetic oil can deal with the 20000 between oil changes, it’s just the high risk of engine damage from...

MSc in Space Technology and Engineering, so while I don't own a single spanner I have a very extensive knowledge of filters, lubricants, and particularly fuels, so I do know about things like lifetime fills. With modern machining tolerances etc, 20k mile oil intervals is perfectly fine if the...

From memory it takes 0.5L to raise from minimum to maximum oil level on the dipstick. Being 1.5L below minimum is very low. My 2016, CFCA 180ps oil level does not visibly reduce between annual oil changes (8-10K miles) and oil analysis does not show fuel dilution.

Reassuring as I just checked mine before we head off for summer hols and it’s the same level as yours. I too had a good look all round and squeezed the boots - all dry, no signs of a leak anywhere. I imagine it’s never been topped up. Will do this and keep an eye, feeding back if anything new...

Hi all, I recently picked up a 2009 VW Transporter 1.9 TDI as a non-runner project, and I'm having trouble getting it to start. I was told it wasn’t starting when I bought it, so this wasn’t a surprise, but I’m hoping someone can help point me in the right direction. Here's what’s happening...

...so he would perhaps advise changing the sensor, so at least you know you are back at square one. He (as does Sasquatch and I) think the oil dilution (in the main - there are always exceptions) should not be excessive. Yes, you will get some fuel leak past the piston rings, perhaps more so...

2% dilution is a cautionary level, 4% is the potential lubrication failure level for Diesel engine lube oil analysis. While there have been significant improvements in synthetic oil properties I think the source of the ‘don’t worry‘ opinion is the motor manufacturers themselves. Let’s face it...

As @DaveD said plus engine power is lost in churning oil and there is a far greater risk of crankshaft oil seal failures which are already a weak point on the T6. More importantly if the oil level increase is down to fuel dilution it is destroying the engine and turbochargers.

Always a good idea to regularly check the oil level and visual condition. Lights and bells are usually activated well after action should have been taken. It is possible to have fuel dilution and not have a raised oil level if the engine is consuming oil. Oil analysis is the only 100% guaranteed...

Hi everyone I really need some advise as I’m clueless and just the designated driver of T6,1 2021, 2.0 TDI, 12k miles After several hundred miles of motorway driving (2hrs / 1hr break / 2hrs) a warning light came on: ‘Oil level too high: workshop!’ I left it overnight and dipstick indicates...

Fuel dilution acceptable limit is 2% so I would get the oil and filter changed asap (if it were still running). You have 12000 miles entered as the oil mileage at the time of sample, is this correct? Seems odd to have such a round number. Without higher iron and alum’ content it would indicate...
