Your TDI has been running 'high quality' B100. Bio is not of consistent quality in this country. I remember a post where you commented that it didn't run quite as well as it did in the past. Perhaps that's why. I am not against running bio. I prefer it when I can get it. However my car is old tech and you can run lots of stuff through it that you can't run through the newer DI diesels without trouble. A newer car with extremely high tech injection would only get what the mfg recommended as I wouldn't want to buy an engine or junk a car. Common sense prevails. I don't want to have to argue with the dealer over why MB should pay for an engine. This approach certainly lacks finesse. bluehorizon wants to run SVO in a CDI. Can you say no way Jose? Reread my post please. Running straight oil in that car will be trouble; I know now that no one here believes this so I encourage everyone to try, come back and post the results. Stay tuned, I'm going to find that reading material for you. If I recall I read it on the MBCA forums, about a year ago.

You are correct in saying that biodiesel is not of consistent quality. That is why I check with the supplier if the batch of fuel has been tested and meet ASTM specs. If they cant provide me with the test results then i wont risk running the engine on fuel of unknown quality. I constantly refer to this thread on how to find out if the biodiesel is of high quality and not bunk bio. http://forums.tdiclub.com/showthread.php?t=110004&highlight=pd+tdi+biodiesel "How-To: Using BioDiesel in PD-TDIs... begin by requesting and reviewing recent ASTM test results for the fuel. if your BioD supplier cannot provide you with recent ASTM test results for their fuel, my recommendation is "do NOT put it in your PD"."

The e320s run with B100 in Europe all the time, but it is EU standard fuel, not US.

I know of many hundreds of people running these New style Common Rail, HDi, CRDI, TDDI, MPi, Uni-Jet etc!(Including the CDi series Mercedes-Benz) on 100% BioDiesel with No Problems, and have done for a number of years. I know this, because They are My Customers for my fuel....  A Leading supermarket chain here in the UK sells a B30 blend and most makers now will honour warrantee for this popular fuel.... I even know of a couple of CDi Sprinter vans converted to Twin-Tank using straight veggy oil....They have been running a couple of years now too Dont be TOO QUICK to poo-poo something just because its not liked by some.....  BTW, The Warranty issue is Non issue..... The maker of the car, (In this case M.B.) do not warrant the fuel-system..... That would be Bosch. (assuming a Bosch system fitted....) Bosch guarantee the fuel-system they supply to M.B. They (M.B.) pass this guarantee on to you the Customer as part of the warranty. Now- The Common-Position-Statement, signed by All Major Injection equipment manufacturers......... This is the arrangement entered into by the FIE (Fuel-Injection-Equipment makers, ) such guys like Stanadyne, Bosch, Siemens, Diesel-Kiki, Denso, Delphi, Lucas/Varsity et. al... These guys have grouped together and come up with a warranty claim system, with regards to Fuel. What this actually says is-- If the fault can be attributed to the fuel, then the warranty claim should be rejected. This applied to ANY fuel--Including your beloved D2  .The fact that there is BioDiesel in the fuel-system is NOT a reason in itself to reject the warranty claim. They MUST PROVE that the FUEL has caused the faults, before they reject the warranty claim.....If you would like me to 'cut/paste' the F.I.E. Common-Position Statement, (Ex Delphi Direct C.D.) I will...... NO Fuel Testing and all that rubbish spouted earlier--Thats just total hearsay/nonsense......  Don't Knock it, Till You try it.....

MB does make the engine the bosch stuff is attached to and their approved use of Bio is limited to 5%.

Alastair, FYI I'm not a D2 lover and I wish I could get my hands on some quality biodiesel, especially the 2nd-generation kind. I did use B50 on a few occasions, until it just became too much of a hassle. I like biodiesel because of the higher lubricity & cetane, but I won't use it if I have to get raped getting it.
Biodiesel does have relatively low oxidative stability. I don't think there's enough evidence yet to say one way or another whether high blends are reliable, especially in high-pressure fuel systems where deposits may form. Also the new generation of clean diesels are supposedly incompatible with biodiesel, at least that's what the manufacturers claim. This concerns the purging of the particulate filter where the specific burning properties of D2 are relied upon. I agree with you regarding the rejection of warranty. However it's not too difficult for a dealer to "prove" that your bio mix has caused problems if you're foolish enough to bring your car in with fuel system problems and a tank full of bio.

The 'D2' comment wasn't directed at anyone specifically, Sorry if it sounded as such....
Unfortunately the 'premium' attached to BioDiesel by the 'tree-hugger' brigade doesnt help in its uptake. Of course people are not going to use it if its perceived as too expensive--Except the 'minority' of course.... The Oxidation stability is directly related to the feedstock oils. Soy based biodiesel (apparently common in the U.S...?) has a poor oxidation stab. but conversly, Rape M.E. is very good. There are specific additives such as Baynox that improve the stability tremendously. Quality Biodiesel conforming to ASTM and EN standards will have been tested for oxidation stab. as a part of the 20 odd tests that comprises the ASTM/EN Standard.... Providing the fuel has been made to a very high standard it will be as safe, if not better in most vehicles. Unfortunately, There is a LOT of really cruddy fuel out there which gives it ALL a bad name.... DPF issues.... Well, PSA-the makers of Citroen and Peugeot vehicles fit DPF systems to most of their ranges with Diesel engines these days. These vehicles are warranted to use 30% BioDiesel and will not affect the operation of that system. Its interesting to note the reason why there 'Could' be an issue with the DPF system. Periodically, the engine-management will deliver fuel on the Exhaust-Stroke so as to clean this filter.... The issues with BioDiesel, is not that it wont clean the DPF, but rather will contaminate the lubricating oil, by way of hitting the cylinder-walls. This is expected and doesnt matter with std. D2.... Std. diesel will evap out f the lube, and be routed via the oil-breather system to the inlet-manifold where the vapour will be burned.... BioDiesel doesnt evap out of lube-oil, so can build up. This could cause issues if the vehicle isnt serviced correctly.... A responsible BioDiesel supplier will know this issue and advise his customers accordingly to change the lube at half the makers recommendations when running BioDiesel..... Another issue is that POOR quality fuel could cause the Adblue cartridge to be used up too quick, but this usually only happens when some pilluck tries to use straight veg in his new HDi or what-have-you..... BTW, The 'Main Stealer' will not diagnose the fault that caused an injection-pump or injector to fail.--They will diagnose its faulty, and change it--never what CAUSED it to fail--- They are specifically told NOT to open such devices up, as to do so, would break seals and often special tools are needed for daft 'security type' screw-heads,... but to return them to parts HQ for shipping to Bosch (Or whoever...)--Therefore, it would be impossible (Unless cruddy and obviously 'faulty' fuel was found in the vehicle) for the Main Stealer to diagnose whether the Fuel had actually CAUSED the fault. He MAY Suspect, but it HAS to be proven to be sited as the warranty claim rejection--Its a legal issue.... (Dealers themselves dont really care who pays. Its easier for them just to replace a part under warranty than reject the claim and have a very unhappy customer in their show-room, when they are trying to sell that new ML320!) BTW, When was the last time you heard of BioDiesel causing a valve to fail or a piston to blow through....? Engines themselves don't know or care what they are fed with providing its of suitable quality and combustability, which good BioDiesel obviously is!

small concentrations of bio maybe, but definitely do not attempt SVO. These cars have been converted to SVO and have had major problems, I've seen it first hand. It may run fine at first, but it will have major problems with in 30-50K, if not sooner. Never grease a bluetec, never. If you want to run SVO, do it an older car.
I am not anti SVO at all, I have run over 200K since 2000 on SVO and love it all the way, but not in a common rail, especially bluetec (or any other exhaust after treatment) equipped common rail. They are just too expensive to fix. Ruining fuel systems, exhaust systems and perhaps engine/turbo in these cars would be extremely expensive. IDI:Best, the ultimate DI: I have had good luck with an older TDi, drove it 75 K on SVO (275K total) ran great when sold, I'm fine with SVO in these if cared for properly. PD Tdi: no thanks CDI/CR: No way
